What makes a Nazi?

The user's manual for today's pro-Hamas demonstrators
The user’s manual for today’s
pro-Hamas demonstrators

If you have any doubts that we live in a revised version of 1930s Germany, you need only open your eyes for only a few seconds and read these stories below. The list is hardly comprehensive, as it only provides a small sampling of the vicious, violent, and hateful demonstrations, riots, and violence that began after October 7th in support of the rape, torture, and murder by Hamas of more than 1,400 Israelis, many of whom were women and children, and have since morphed into an anti-Jewish compaign designed to intimidate and oppress Jews everywhere, merely because they are Jews.

The mob in front of the Israeli embassy in the third link above made very clear, in blunt chants, what all these pro-Hamas demonstrators want, as well as who they are:

The nearest star-forming region, as seen in infrared by Webb

The nearest star-forming region, as seen by Webb
Click for original image.

Time for another cool image on this somewhat quiet Monday. The false-color infrared image to the right, reduced and sharpened to post here, was taken by the Webb Space Telescope, and shows the Rho Ophiuchi star-forming region, the nearest to our solar system at a distance of about 460 light years.

It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disc, the makings of future planetary systems.

The young stars at the centre of many of these discs are similar in mass to the Sun or smaller. The heftiest in this image is the star S1, which appears amid a glowing cave it is carving out with its stellar winds in the lower half of the image. The lighter-coloured gas surrounding S1 consists of polycyclic aromatic hydrocarbons, a family of carbon-based molecules that are among the most common compounds found in space.

There are two features that are most compelling to me in this image. First, the red hydrogen jet that cuts across the entire right half of the image from top to bottom. At the top you can see how that jet is pushing material before it. Second, we have the cave-like structure surround S1, the central star. The yellowish cloud is almost like a hand cupped around that star.

A galaxy of violence

A galaxy of violence
Click for original image.

Time for another cool image! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope, and shows a well defined spiral galaxy face-on in optical wavelengths.

This whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core, known as an active galactic nucleus (AGN), so it is referred to as an active galaxy. Even more specifically, it is categorised as a Type-2 Seyfert galaxy. Seyfert galaxies host one of the most common subclasses of AGN, alongside quasars. Whilst the precise categorisation of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby ones where the host galaxy remains plainly detectable alongside its central AGN, while quasars are invariably very distant AGNs whose incredible luminosities outshine their host galaxies.

In contrast, the core of our own Milky Way galaxy is very quiet, which is likely a factor in why it was possible for life to form on Earth.

Webb takes another infrared image of Uranus

9:32 am

Uranus as seen in infrared by Webb
Click for original image. Go here for Uranus close-up

Astronomers have used the Webb Space Telescope to take another infrared image of Uranus, following up on earlier observations with Webb in April.

The new false-color infrared picture is to the right, cropped, reduced, and enhanced to post here. Though the close-up of Uranus is in the left corner, the overall view is somewhat wider than the image I highlighted previously, showing many background galaxies and at least one star. The star is the spiked bright object on the left. In false color the galaxies all been given an orange tint, while the blue objects near Uranus are its moons. Because Uranus’s rotational tilt is so extreme, 98 degrees compared to Earth’s 23 degrees, its north pole is presently facing the Sun directly, and is in the center here.

One of the most striking of these is the planet’s seasonal north polar cloud cap. Compared to the Webb image from earlier this year, some details of the cap are easier to see in these newer images. These include the bright, white, inner cap and the dark lane in the bottom of the polar cap, toward the lower latitudes. Several bright storms can also be seen near and below the southern border of the polar cap. The number of these storms, and how frequently and where they appear in Uranus’s atmosphere, might be due to a combination of seasonal and meteorological effects.

The polar cap appears to become more prominent when the planet’s pole begins to point toward the Sun, as it approaches solstice and receives more sunlight. Uranus reaches its next solstice in 2028, and astronomers are eager to watch any possible changes in the structure of these features. Webb will help disentangle the seasonal and meteorological effects that influence Uranus’s storms, which is critical to help astronomers understand the planet’s complex atmosphere.

If you want to see what Uranus looks like to our eyes, check out the Hubble pictures taken in 2014 and 2022. Though fewer features are visible in optical wavelengths, those two images showed long term seasonal changes.

Webb has now revealed some shorter term changes.

UK finally gives Saxavord spaceport a license

11:33 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea.

The Civil Aviation Authority (CAA) in the United Kingdom finally issued a spaceport license today to the Saxavord spaceport on the Shetland Islands, thirteen months after the application was submitted.

This license however does not mean that launches will take place anytime soon. First, Saxavord will have to resume construction of its facilities, which ceased earlier this year because of the CAA hadn’t issued the permit. Moreover, this license does not allow launches. As noted by the CAA:

Spaceport licences allow a person or organisation to operate a spaceport, they are granted in the UK under the Space Industry Act 2018 (SIA). For a launch to happen an operator will need to have developed and proven their technology, be operationally ready, and have a launch licence from the UK Civil Aviation Authority. [emphasis mine]

The highlighted language is especially crushing, because it literally forbids the launch of any new untested rocket. Since every single rocket so far being developed for these two spaceports is new and untested, none will be allowed to launch unless they move operations elsewhere. This requirement explains for example why the startup ABL shifted its next launch from the Sutherland spaceport — it had hoped to launch this year — to Kodiak, Alaska. Orbex will have even more problems, as it has signed a fifty year lease to launch its new Prime rocket from Sutherland, with its rocket factory close by. If it can’t test fly Prime from Sutherland the company will be very badly hampered.

Even if these companies eventually get launch licenses for their untried rockets, expect such approvals to take a very long time, based on the CAA’s past and present history. It took the CAA almost a year to approve Virgin Orbit’s launch license, essentially bankrupting the company.

Nor are my conclusions here — which I have been stating now for more than a year — simply opinions. They have now been confirmed by a new report issued only a few days ago by the UK Space Agency, which admitted the following:

Chinese pseudo-company launches satellite

9:45 am

The Chinese pseudo-company Ispace today launched what is only described as a “prototype recoverable experiment spacecraft” by another Chinese pseudo-company, its Hyperbola-1 rocket lifting off from the Jiuquan spaceport in the northwest of China.

China’s state-run press now routinely makes no mention of these pseudo-companies. In the past China would tout them in an effort to make the rest of the world believe, falsely, that it had its own competitive and growing space industry. Now it appears the Xi government has decided it doesn’t like the growing and somewhat independent success of these companies, and is making it clear to all that, in the end, everything they do belongs to the government.

The leaders in the 2023 launch race:

91 SpaceX
61 China
17 Russia
8 Rocket Lab
7 India

American private enterprise still leads China in successful launches 104 to 61, and the entire world combined 104 to 96. SpaceX now trails the rest of the world combined (excluding American companies) 91 to 96.

Environmental groups file another complaint attempting to stop SpaceX launches at Boca Chica

3:45 pm

In what is now becoming a routine process of harassment, several environmental groups have filed another complaint against the FAA and Fish & Wildlife for eventually issuing a second launch license to SpaceX, permitting it to do its mid-November second orbital test launch of its Starship/Superheavy rocket from Boca Chica, Texas.

In the supplemental complaint, the groups — Center for Biological Diversity, American Bird Conservancy, Carrizo/Comecrudo Nation of Texas, Inc., Save RGV and Surfrider Foundation — allege the FAA failed to properly analyze the environmental impacts of the first Starship launch before issuing a revised license for the second launch that took place Nov. 18.

That new licensing process included an environmental review by the U.S. Fish and Wildlife Service (FWS) regarding a pad deluge system that SpaceX installed on the pad to prevent damage like that the pad suffered during the first launch. The FWS concluded that the deluge system would produce no significant environmental changes.

The environmental groups argue that both FAA and FWS fell short of what was required under the National Environmental Policy Act (NEPA) to review the environmental impacts of Starship launches. The FAA, it stated in the complaint, “once again failed to take the requisite ‘hard look’ at the impacts of the Starship/Superheavy launch program through a supplemental NEPA analysis.”

Let me translate what this complaint really says, and I can do it only a few words: “Your review didn’t come to the conclusions we want — which is to block all work by SpaceX — so that we can do what we want!” Both the American Bird Conservancy and the Surfrider Foundation simply want unlimited access to the region for their own recreation, while the Center of Biological Diversity is only interested in stopping all human development anywhere — until it can settle its frequent lawsuits against the government and pocket its payoff.

As for Carrizo/Comecrudo Nation of Texas and Save RGV, both are bogus organizations. The first is for a almost non-existent Indian tribe that never even lived in this area (they were based in Mexico), and the second claims it represents the people of the south Texas region who want SpaceX’s work stopped. Since almost everyone in Brownsville and throughout the region is celebrating the new prosperity brought to them by SpaceX, it is essentially a front group for the Marxist environmental movement that hates all prosperity. It doesn’t represent anyone really in south Texas.

As before, this complaint will have to be fought, wasting time and money.

Russia launches weather satellite

3:29 pm

Russia early today successfully launched a new weather satellite, the second in a new constellation, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan.

The flight path took the rocket north, with its lowers stages crashing in landing zones in Russia.

The leaders in the 2023 launch race:

91 SpaceX
60 China
17 Russia
8 Rocket Lab
7 India

American private enterprise still leads China in successful launches 104 to 60, and the entire world combined 104 to 95. SpaceX now trails the rest of the world combined (excluding American companies) 91 to 95.

Chevrolet – A Holiday to Remember

6:01 pm

An evening pause: Yes, I know it is a commercial, but it is right for the season. And it reminds us of the never-ending human desire — not often possible — to always believe all things can be made better. Such a belief enriches us. We should never lose it, no matter how bad things become.

Hat tip Mike Nelson.

  • Relativity touts its newest rocket engine

    • After its first and only test launch of its Terran-1 rocket, it went back to the drawing board, shifting to its bigger Terran-R rocket. This tweet is its effort to gain some press, since it will not be launching again for several years.
