The health dangers of wearing a mask improperly

1:40 pm

Our new dictators in government and its bureaucracies are now attempting to impose a new “normal” on society, demanding that everyone where a mask wherever they go in public. They claim this is to “slow the spread of COVID-19”, but if you try to pin down the actual science that supports this claim, you will routinely have trouble finding it.

What you instead will find is that there is substantial peer-reviewed research that not only questions the usefulness of widespread mask use by the public in ordinary settings, but also notes serious health risks that can be caused by the masks themselves.

Today I want to take a look at the failure and absurdity of widespread mask use, using as my guide the very instructions given by the Mayo Clinic and the World Health Organization (WHO). What I am going to do is review these instructions, step-by-step, noting the absurdity of their expectations and the risks they scoff over so nonchalantly.

First, let’s look at the claims made by the Mayo clinic:

Amazing layers

11:07 am

Bedrock layering in Holden Crater
Click for full image.

Cool image time! The science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) today released a cool captioned image entitled “Exquisite Layering”, showing a place on the floor of Holden Crater where the dust and sand that normally covers most of the Martian surface has been wiped away, cleared off because these layers are on higher sloping terrain.

The image to the right, cropped to post here, focuses in on that exposed layering, believed to be sedimentary and must have therefore happened in the eons following the impact that caused the crater.

Overview map

The overview map to the right shows with the red box the location of this layering inside Holden Crater. The map also illustrates why this crater was considered a candidate landing site for Curiosity. Like Gale Crater, it has evidence — the large meandering canyon system flowing into the crater — that suggests it had once been filled with a water lake. These sedimentary layers support that hypothesis, suggesting that this lake was intermittent. Each time it refilled and then dried up, it laid down a new deposit of those sedimentary layers.

Almost all COVID-19 deaths occur in long-term nursing homes

9:06 am

Not only has the death rate for the Wuhan flu inflated falsely by government officials, they have obscured the fact that almost all the deaths have occurred not in the general population but within long term medical health facilities for the elderly.

Fact #1: 1.7% of the population in the US resides in long-term medical care facilities (LTMCFs) and total 5.7 million.

Fact #2: The residents of LTMCFs accounted for 38,800 or 53% of all COVID-19 deaths (based on recent data). The rest of the country, the 98.3%, have experienced approximately 34,600 deaths, or 47% of the nation’s total COVID-19 deaths.

That means the death rate, deaths expressed as a percent of those living in medical care institutions, is 0.682%, more than 50 times the death rate of the rest of the population at 0.012%. The death rate for the overall populations is 0.022%.

That should leave you speechless.

In other words, the death rate for the Wuhan flu is pretty much the same as the flu, and is really only a threat to the elderly sick. Protect that population, as Florida did, and you reduce the risk to everyone to practically nil.

Which means the demands upon us all — the lock downs, the social distancing, the requirement to wear masks — are all fake theater and are pointless in all ways but one: They give power to the thugs now running our government.

COVID-19 deaths likely inflated by a minimum of 25%

8:57 am

The number of people listed daily by state governments throughout the United States are likely inflated by 25%, based on the policies from numerous different health departments.

The policy has been to count any death with even the slightest hint of the Wuhan flu, even without any tests, to be caused by it. This was discovered in Colorado when they listed a death as caused by coronavirus, when in reality it was a drunk who died from alcohol poisoning. The state was forced to change its counting system, slightly.

Colorado has switched to a dual recording system. It still keeps a broader category of “deaths among cases,” and the smaller category of “deaths due to.” But you have to go directly to its web site to see that. The number still reported to the CDC and thence to data aggregation sites like Worldometers or the Johns Hopkins Coronavirus Resource Center to count Colorado deaths and U.S. deaths remains “deaths among.”

The dual system essentially amounts to an asterisk. Nevertheless, the difference is marked. The “due to” category is about a fourth smaller than the “caused by” one. And there’s no reason to think it’s different in other states. So when the nation hits the 100,000 Covid-19 death mark soon, if you subtract 25%, it would still be proportionately far less than half the 1968-1969 “Hong Kong Flu” (H3N2) which killed an estimated 100,000 Americans at the time — or 170,000 when adjusted for U.S. population increase.

And no, the economy wasn’t destroyed and constitutionally protected civil liberties suspended for the Hong Kong Flu.

Democratic Party states like Pennsylvania, New York, Illinois, and others have all been found to fudge their numbers in the same way, and don’t yet make it obvious that they are doing so.

Weather improves for tomorrow’s manned Dragon launch

8:39 am

Capitalism in space: The weather outlook has brightened tomorrow, increasing the chances that the SpaceX’s manned Dragon capsule will launch as scheduled.

No major technical issues of any significance were under discussion Monday, but the weather could be a factor. Forecasters initially predicted a 60% chance of a weather-related launch rule violation, but Mike McAleenan, launch weather officer with the 45th Weather Squadron, said conditions appeared to be improving somewhat. “If I was to issue the forecast today, right now we would probably be down to 40% chance of violation,” he said. “We have a bit more rain to go here and maybe another round of afternoon thunderstorms tomorrow, but … it looks like much less (cloud) coverage. So we have some hope for launch day.”

But McAleenan’s forecast does not include downrange conditions in the Atlantic Ocean along the Crew Dragon’s trajectory where Hurley and Behnken could be forced to ditch in the unlikely event of a catastrophic booster failure during the climb to space.

SpaceX managers will assess a complicated mix of weather models, high-altitude balloon data and actual wind, rain and wave data from multiple buoys along the ground track to determine whether conditions, on average, are acceptable for launch.

The launch is set for 4:33 pm. I will embed SpaceX’s live stream here on Behind the Black tomorrow earlier in the day, when things begin..

West Point Band and Glee Club – Mansions of the Lord

6:01 pm

A evening pause: For Memorial Day. The words:

To fallen soldiers let us sing
Where no rockets fly nor bullets wing
Our broken brothers let us bring
To the Mansions of the Lord
No more bleeding, no more fight
No prayers pleading through the night

Just divine embrace, eternal light
To the Mansions of the Lord.
Where no mothers cry and no children weep
We will stand and guard though the angels sleep
Through the ages safely keep
The Mansions of the Lord.

LauncherOne flight terminates early

2:26 pm

Capitalism in space: The first demo flight of Virgin Orbit’s LauncherOne rocket ended almost immediately after the rocket made a clean separation from its 747 first stage.

Cosmic Girl took off just before 12 PM PT (3 PM ET) from Mojave Air and Spaceport in California. The aircraft was piloted by Chief Test Pilot Kelly Latimer, along with her co-pilot Todd Ericson. The aircraft then flew to its target release point, where LauncherOne did manage a “clean release” from the carrier craft as planned at around 12:50 PM PT (3:50 PM ET), but Virgin noted just a few minutes later that the mission was subsequently “terminated.”

No one was hurt in the failure, but no word yet on what happened.

They had warned that this first test flight might not reach orbit. Nor should anyone be surprised, as first flights of rockets often fail. Nonetheless, this failure will hurt the company effort to gain launch contracts.

In space exploration, freedom wins again

1:56 pm

Douglas Hurley and Robert Behnken, with Falcon 9 in background
Dragon astronauts Douglas Hurley and Robert Behnken
with their Falcon 9/Dragon in the background

This week we shall once again see a demonstration of the power of freedom, and it will not be a demonstration by protesters in Hong Kong or Michigan or New York against the petty dictators who rule them.

No, it will simply be the launch of an American rocket, owned by an American company, putting two Americans in space. While most reports of the manned Dragon launch on SpaceX’s Falcon 9 rocket will properly focus on the new engineering and the specific achievement — the first American manned space mission in almost a decade — few will recognize how it is freedom, that forgotten word, that more than anything made it possible.

And it has always been this way, since the very beginnings of the space age. As John Kennedy expounded in his 1961 speech committing the U.S. to a lunar landing, that commitment was to demonstrate that a free people and nation could do it better:

Launch date for UAE’s Hope Mars orbiter set

9:27 am

The new colonial movement: Japan and the United Arab Emirates (UAE) have set the launch date for UAE’s Hope Mars orbiter, now scheduled for July 15 with a launch window that closes on August 13.

If all goes well it will enter Mars orbit in February 2021.

The probe is a UAE project in name only. Much of it was built in the U.S. by U.S. companies, working with UAE engineers and scientists. It is also being launched by Japan.

Regardless, the training and knowledge obtained by those UAE engineers and scientists is the real point of the mission. The UAE wants to diversify its economy away from oil, and it is trying to use the excitement of space exploration to do it. It hopes these engineers and scientists will use what they learned to come up with new projects that in the future will be built entirely in the UAE.

Russia says it will oppose Artemis Accords

9:18 am

My heart be still: Roscosmos head Dmitri Rogozin declared today that Russia “will not, in any case, accept any attempts to privatize the Moon.”

“It is illegal, it runs counter to international law,” Rogozin pointed out.

The Roscosmos CEO emphasized that Russia would begin the implementation of a lunar program in 2021 by launching the Luna-25 spacecraft to the Moon. Roscosmos intends to launch the Luna-26 spacecraft in 2024. After that, the Luna-27 lander will be sent to the Moon to dig up regolith and carry out research on the lunar surface.

Rogozin is doing the equivalent of a 2-year-old’s temper tantrum. Being a top-down authoritarian culture that likes to centralize power with those in charge, Russia doesn’t like Trump’s effort to regularize private enterprise and private property in space, including the administration’s new requirement that any international partner in its Artemis Moon program must agree to that effort.

Russia would rather we maintain the status quo as defined by the Outer Space Treaty, with no private property in space and everything controlled by UN bureaucrats and regulations, who are in turn controlled by the leaders from authoritarian places like Russia.

If Russia wants into Artemis, however, it looks like they will have to bend to the Trump accords. Or they will have to build their own independent space effort, competing with ours. Their problem is that their own program has been incredibly lame for the past twenty years, unable to get any new spacecraft or interplanetary mission off the ground.

Maybe the competition will help Russia, as it did in space in the 1960s. Or maybe they will simply help Biden get elected, and then all will be well! That brainless puppet will be glad to do the bidding of Russia and China, and will almost certainly dismantle Trump’s policies in favor of private enterprise.

More good news on the Wuhan flu front

8:59 pm

Two stories today suggest again that there is no reason to fear COVID-19, especially if you are healthy and young.

The first story suggests that social distancing, masks, and the incessant cleaning of surfaces are ridiculous over-reactions and likely unnecessary. Nor am I surprised. We have always had similar expectations from all other flu-like illnesses, and have never required these paranoid requirements in the past. It is time for them to stop.

The second story provides more evidence that the epidemic is dying, as predicted and like all similar flu-like epidemics.

The team has recruited 10,000 people to test the vaccine, some of whom will be given the vaccine and others a placebo. But as it is unethical to purposely infect people in the trial with COVID-19, participants will be asked to go about their normal routine in the expectation that some will be exposed to it naturally. However, that is unlikely to happen if the virus is not spreading, meaning that no conclusions can be drawn one way or the other about the vaccine’s efficacy.

Hill expects that fewer than 50 people in the test population will catch the virus, but if less than 20 test positive the results may be useless “It is a race, yes. But it’s not a race against the other guys,” he said. “It’s a race against the virus disappearing – and against time. We said earlier in the year that there was an 80% chance of developing an effective vaccine by September. But at the moment, there’s a 50% chance that we get no result at all.

Let me repeat this: They have 10,000 volunteers, and expect fewer than 50 of those to get infected with the Wuhan flu. In other words, this seasonal epidemic is going away, as such things do. It might return in the fall, but expect that return to be smaller, and hopefully if some government officials get their brains out of their behinds and focus on protecting the sick elderly, it will have little impact.

In any case, the evidence continues to point to the end of the epidemic, and in the process the discovery that the virus is relatively harmless to almost everyone. People have got to relax and stop being so afraid. It is not the bogey-man the press and the politicians have claimed it to be.

Court rules fossils belong to landowners

9:12 am

The Montana Supreme Court has ruled that any fossils found on private land belong to exclusively to the landowners, and that no rights accrue to any owners of the land’s mineral rights.

The Montana Supreme Court this week ruled that fossils are not legally the same as minerals such as gold or copper. Therefore, Montana fossils, including a dramatic specimen of two dinosaurs buried together, belong to people who own the land where they are found, rather than to the owners of the minerals underneath that land.

The 4-3 decision upholds the way U.S. scientists have long approached questions of fossil ownership. It appears to defuse a potentially explosive 2018 ruling by the federal 9th Circuit U.S. Court of Appeals that fossils went to the owners of mineral rights.

The outcome is a win for scientists who had warned that tying fossils to mineral rights could make it harder to get permission to excavate and could throw into doubt who owns fossils already on display, says David Polly, an Indiana University paleontologist and past president of the Society of Vertebrate Paleontology.

Because the earlier 2018 federal court decision was later appealed and the court then referred the case to Montana’s Supreme Court, this decision settles the dispute nationally as well.

That absurd 2018 9th Court of Appeals decision illustrates how insane that specific federal court had become, packed with many radical leftist and partisan Democratic judges. In the past three years however the balance of that court has been significantly changed, so expect fewer such crazy rulings.

Florida’s successful response to COVID-19, based on the DATA

12:15 am

This review of the success of Florida’s government, led by Republican Governor Ron DeSantis, in containing the Wuhan flu epidemic while not shutting down his state unnecessarily, can be summed up with this one quote from the article:

So how did DeSantis go about responding to the epidemic? It began with the data.

At the outset, DeSantis looked at South Korea’s experience, Then there was Italy: “I think the median age of fatality was something like 82 in some of those areas in Northern Italy … That really helped inform the strategy to focus most of our efforts on the at-risk groups.”

The DeSantis team also didn’t put much stock in dire projections. Instead, “we started really focusing on just what we saw.” [emphasis mine]

What the DeSantis team did was focus on protecting the elderly population, as shown by the data, while allowing the rest of the younger population to pretty much go about their business.

At the same time, Florida was giving its counties latitude in how they reacted to the crisis. “I said from the beginning,” DeSantis explains, “we’re a big, diverse state. Even at this point, 60 percent of our cases have come from just three counties.”

DeSantis issued his own statewide order, but he argues that it was more flexible and less prescriptive than those of other states. “We basically had businesses operating. We had the day cares open, we had recreation open, and my order never actually closed any businesses. We allowed them to operate within the context of just limiting contact between people outside the household.” [emphasis mine]

If only more governors had taken this common sense, rational approach, based on the available data, not on models that were nothing more than panicked opinions of doom. Had more done this, there would have been less panic, fewer businesses nationwide destroyed, fewer old people in nursing homes dead in New York, Michigan, and other Democratically-controlled states (where their idiotic governors forced infected patients into nursing homes), and millions still employed in viable prosperous businesses.

Instead we are now faced with a possible depression, imposed on us by incompetent governors nationwide.

CDC confirms COVID-19 tiny death rate, comparable to flu

9:35 pm

Are you enraged yet? The CDC has confirmed that the death rate for the Wuhan flu is probably less than 0.4%, slightly higher than the flu’s 0.1%, but when all factors are considered, including the data that shows it is almost completely harmless to everyone but the elderly who are chronically sick, the disease is essentially just another new flu epidemic, requiring no extreme measures other than acting to protect the vulnerable.

Plus, ultimately we might find out that the IFR [infection fatality rate] is even lower because numerous studies and hard counts of confined populations have shown a much higher percentage of asymptomatic cases. Simply adjusting for a 50% asymptomatic rate would drop their fatality rate to 0.2% – exactly the rate of fatality Dr. John Ionnidis of Stanford University projected.

More importantly, as I mentioned before, the overall death rate is meaningless because the numbers are so lopsided. Given that at least half of the deaths were in nursing homes, a back-of-the-envelope estimate would show that the infection fatality rate for non-nursing home residents would only be 0.1% or 1 in 1,000. And that includes people of all ages and all health statuses outside of nursing homes.

There’s more. Read it all.

What infuriates me the most is that the early data (not the fake models) all pointed in this direction, quite clearly, as noted in detail in this March 17 post, just when panicked state governors were beginning to impose totalitarian rule by edict. Even then it was clear that lock downs made no sense, and would only worsen the situation.

I repeat: Any disease like this requires a rational aggressive and focused response. We can’t ignore it. People need to voluntarily self-quarantine if they feel sick, or if they have older and sick relatives living with them. We should also wash our hands regularly, and avoid unnecessary physical contact with many other individuals.

At the same time, we mustn’t waste our energies doing things that are unnecessary, foolish, or downright counter-productive, such as releasing entire prison populations into the general population.

We also should be outraged by politicians who are using this situation not to deal with it but to impose their pet totalitarian rule over the population, such as passing entirely irrelevant gun bans and shutting down businesses willy-nilly and imprisoning everyone in their homes.

These actions will do little to ease the epidemic. Instead, they might worsen the situation by causing panic (as they have apparently done). Panic is not what this situation warrants. Instead it needs a calm rational response, something that only civilized rational people can give it.

Are we that? Watching what is happening I must sadly say I have my doubts.

In retrospect, it appears if many of our leaders have any rationality, they apply it exclusively to creating schemes for increasing their power and ability to oppress everyone else. Serving the nation and its citizenry appears the last thing on their mind.

U.S. universities have pocketed $6 billion from hostile enemy countries

8:57 pm

Our new fifth column: An investigation by the Department of Education has found that U.S. universities have taken $6 billion in unreported donations from hostile coutnries, all of which could be in violation of the law.

A probe by the Department of Education into colleges that accept foreign investments and donations has uncovered $6 billion in previously unreported foreign donations from US adversaries including China and Russia, a report said Friday.

House Republicans were monitoring the investigation into the schools to determine if they were violating Section 117 of the Higher Education Act of 1965, which prohibits an “Institution of Higher Learning” from failing to properly report foreign gifts of $250,000 or more, Town Hall reported.

It also appears that some of those universities are now uncooperative, apparently placing their loyalties more with their foreign backers than with their own country.

This evidence is not surprising, and is reinforced by the numerous arrests in recent months of many university professors taking money secretly and illegally from China. The culture in the American university community has been downright hostile to the United States for decades. In the past it was dressed up as their effort to not be jingoistic. That was a long time ago. For at least two decades the academic community has been an anti-American fifth column, working as much as it can with foreign powers to both indoctrinate its students against their own country, while providing aid and comfort to authoritarian countries like Russia and China.

More pits found on Mars

3:04 pm

Pit near Hephaestus Fossae
Click for full image.

Overview map

Since 2018 I have made it a point to document every new pit image taken on Mars by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The list of can be found at the bottom of this post.

In the most recent release from MRO, a number of new pits were photographed. All continue to suggest that Mars has a lot of underground voids, some caused by lava flow, some by tectonic activity, some by water ice erosion, and some almost certainly caused by processes we don’t yet know. The images also suggest that we have only identified a small fraction of those underground voids.

The first image to the right, cropped to post here, shows the one new pit in the northern lowlands of Utopia Planitia, near a series of meandering channels and canyons dubbed Hephaestus Fossae and Hebrus Valles.

This appears to be the fifth such pit found in this region. Previously I had documented the first four. The overview map to the right adds this fifth pit. Note how the pit is much closer to the head of Hephaestus. In the full image you can see fissures both to the north and south, as well as many nearby aligned depressions, suggesting the existence of more underground passages, some possibly linked to voids under this very pit.

The pit itself seems filled, with no apparent side passages, though to the southwest there might be something leading off in the shadows.

The overall terrain in this region, including these pits, the fissures, and the many aligned depressions, strongly suggests a lot of underground voids. As I noted in 2019:

Star to get within a trillion miles of Sun in 1.4 million years

10:04 am

Using the precise location and motion data obtained by the space telescope Gaia, astronomers have identified a star that 1.4 million years will come within a trillion miles of the Sun.

That distance puts it well within the outer parts of the theorized Oort cloud at the edge of the solar system. Since the star, Gliese 710, has a mass half that of the Sun, it will thus disturb many objects in that Oort Cloud, causing many to eventually fall sunward and produce a hail of comets several million years later. It will be, for a long time, the brightest object in the night sky, by far.

The data also identified a number of other stars that have in past or will in the future get close to the Sun. The most important result is not that these close approaches occur, but that they have found that they are relatively rare, and even the closest, Gliese 710, never really gets that close.

The universe is big, far bigger than we can really imagine.

“Spots” orbiting Milky Ways central black hole

9:19 am

Using the ALMA ground-based telescope array in Chile, astronomers have detected two energetic “spots” that appear to be orbiting Sagittarius A* (pronounced A-star), the super-massive black hole at the center of the Milky Way.

The spots appear to be regions in the accretion disk surrounding the black hole that are emitting energy.

Their scenario is as follows. Hot spots are sporadically formed in the disk and circle around the black hole, emitting strong millimeter waves. According to Einstein’s special relativity theory, the emission is largely amplified when the source is moving toward the observer with a speed comparable to that of light. The rotation speed of the inner edge of the accretion disk is quite large, so this extraordinary effect arises. The astronomers believe that this is the origin of the short-term variation of the millimeter emission from Sgr A*.

The team supposes that the variation might affect the effort to make an image of the supermassive black hole with the Event Horizon Telescope. “In general, the faster the movement is, the more difficult it is to take a photo of the object,” says Oka. “Instead, the variation of the emission itself provides compelling insight for the gas motion. We may witness the very moment of gas absorption by the black hole with a long-term monitoring campaign with ALMA.” The researchers aim to draw out independent information to understand the mystifying environment around the supermassive black hole.

Everyone please repeat after me: Though this scenario makes sense, based on the facts and our knowledge, there is a lot of uncertainty about these conclusions.

The only opposition that will matter to today’s lock down fascism will be opposition expressed in the ballot box

2:07 pm

In the past week or so there have been numerous stories in the press suggesting that Americans have finally lost patience with the unreasonable Wuhan flu lock downs that have been arbitrarily imposed in the past two months by elected officials, sometimes indefinitely, for no justifiably rational reasons.

In Michigan there were armed protests, and then barbers began publicly defying the lock down orders of their fascist governor.

In New Jersey a health club defied the order of that state’s fascist governor and reopened to cheers from its customers.

In Baltimore a pastor stood at the pulpit and ripped apart the shut down order by that city’s health department.

In Minnesota the Catholic church announced it was reopening for church services, in direct defiance of the orders of that state’s governor.

I could cite many other examples, across the country, in both conservative and liberal states.

Are these push backs necessary? Certainly. These fascist governors and mayors, most of whom have been Democrats, have imposed unreasonable and blatantly illegal arbitrary restrictions on the freedoms of Americans, which must be resisted at all costs.

Are these push backs real? Forgive me if I must sadly remain skeptical. For fifty years I have watched as politicians, mostly from the Democratic Party but with more than ample support from large numbers of Republican Party hacks, have slowly but steadily worked to erode the freedoms of Americans.

Trump exiting Open Skies treaty

11:02 am

According to anonymous sources, Trump has decided to pull the U.S. out of the Open Skies Treaty, negotiated in 2002 to allow countries to overfly other nations freely.

President Trump will be pulling the United States out of the Open Skies Treaty, an agreement between more than 30 countries that allow for those involved to fly in each other’s air spaces, a senior administration official confirmed to Fox News. The New York Times first reported that Trump was planning to withdraw from the agreement, worrying NATO member nations who are concerned that once the U.S. is out, Russia will block their flights, which provide valuable surveillance of their own borders.

U.S. officials have warned that Russia had been violating the treaty already by not allowing flights over areas where military exercises were taking place or sites where Russia had nuclear weapons deployed. Each nation in the treaty agrees to make all its territory available for surveillance flights.

Note also that China is not a signatory.

Not surprisingly, their Democratic Party allies, always ready to aid other countries over U.S. interests, are already blasting this decision by the Trump administration.

Google steals; distorts search results to hide it

10:18 am

Reason 10,328,467 to stop using Google: Google routinely steals the intellectual property of others for its own benefit, and then distorts all search results to hide any news stories that report on this theft.

The author at the article documents in great detail Google’s history of theft. He then compares search results from Google, Bing, and Yahoo to show how Google then manipulates search results to hide any stories that report these thefts.

The bottom line: Stop using Google! There are plenty of other search engines, some of which, like DuckDuckGo, that protect the privacy of your searches. Google is a corrupt, unethical company that needs to lose business, fast.

A Jupiter Trojan asteroid spouts a tail

9:54 am

The ATLAS telescope has discovered the first Jupiter Trojan asteroid to spout a tail like a comet.

Early in June 2019, ATLAS reported what seemed to be a faint asteroid near the orbit of Jupiter. The Minor Planet Center designated the new discovery as 2019 LD2. Inspection of ATLAS images taken on June 10 by collaborators Alan Fitzsimmons and David Young at Queen’s University Belfast revealed its probable cometary nature. Follow-up observations by the University of Hawaiʻi’s J.D. Armstrong and his student Sidney Moss on June 11 and 13 using the Las Cumbres Observatory (LCO) global telescope network confirmed the cometary nature of this body.

Later, in July 2019, new ATLAS images caught 2019 LD2 again – now truly looking like a comet, with a faint tail made of dust or gas. The asteroid passed behind the Sun and was not observable from the Earth in late 2019 and early 2020, but upon its reappearance in the night sky in April of 2020, routine ATLAS observations confirmed that it still looks like a comet. These observations showed that 2019 LD2 has probably been continuously active for almost a year.

While ATLAS has discovered more than 40 comets, what makes this object extraordinary is its orbit. The early indication that it was an asteroid near Jupiter’s orbit have now been confirmed through precise measurements from many different observatories. In fact, 2019 LD2 is a special kind of asteroid called a Jupiter Trojan – and no object of this type has ever before been seen to spew out dust and gas like a comet.

There are a number of mysteries here. First, why should it have suddenly become active, since its orbit is relatively circular (similar to Jupiter’s)? Second, it had been assumed that the Jupiter Trojans had been in their orbits for a long time and had long ago vented any ice on their surfaces. This discovery proves that assumption false. It suggests that either this asteroid is a comet that was recently captured, or that things can happen on these asteroids to bring some buried volatiles up to the surface, where they can then vent.

Above all, this asteroid shows that it is dangerous to assume all Jupiter Trojan asteroids are the same. I guarantee when we finally get a close look at a bunch, when the Lucy mission arrives beginning in 2027, the variety will be quite spectacular.
