The closest supernovae in almost 25 years

Astronomers have spotted the closest supernovae in almost 25 years, only 21 million light years away.

The supernova, dubbed PTF 11kly, occurred in the Pinwheel Galaxy, located in the “Big Dipper,” otherwise known as the Ursa Major constellation. It was discovered by the Palomar Transient Factory (PTF) survey, which is designed to observe and uncover astronomical events as they happen. “We caught this supernova very soon after explosion. PTF 11kly is getting brighter by the minute. It’s already 20 times brighter than it was yesterday,” said Peter Nugent, the senior scientist at Berkeley Lab who first spotted the supernova. Nugent is also an adjunct professor of astronomy at UC Berkeley. “Observing PTF 11kly unfold should be a wild ride. It is an instant cosmic classic.”

Astronomers expect the supernova to continue to brighten over the next two weeks, when it should be visible to anyone using binoculars.

When dust, pebbles, rocks, and boulders act like liquid

The science team of Lunar Reconnaissance Orbiter released an intriguing picture yesterday of what scientists call a granular flow down the side of a five mile wide crater on the far side of the moon. Looking at the image, one would swear that the darker material flowing down the slope of the crater rim is a lava flow frozen in place.

However, according to the scientists, that is not what it is. Instead, this is merely debris left behind from an avalanche.

The immediate consequences of the Progress freighter failure

The immediate consequences of the Progress freighter failure:

The longer term consequences? Congress will anguish over the lack of a shuttle. Some will demand more money for the program-formerly-called-Constellation, while others will demand more money for the new commercial companies. In either case, they will ignore the reality of a bankrupt federal government that simply can’t afford either at the moment.

Many businesses are considering dropping healthcare when Obamacare goes into effect in 2014

Depending on the survey, from 9 to 30 percent of all businesses are considering dropping their employer-sponsored healthcare plans when Obamacare goes into effect in 2014.

In other words, Obama was lying when he said you could keep your plan under Obamacare.

Note too that poll numbers continue to show a solid majority of the public wants Obamacare repealed.

Capturing an asteroid into Earth orbit

orbital path after asteroid capture

Want to mine an asteroid? Rather than travel to it with all their mining equipment, three Chinese scientists have proposed a better way. In a paper published today on the Los Alamos astro-ph preprint website, they have calculated the energy required to shift the orbits of the six thousand near-Earth asteroids and place them in Earth orbit for later mining. Of these, they found 46 asteroids that had the potential for such an operation, and two likely candidates for a space mission. One 30-foot-wide asteroid, 2008EA9, will actually be in the right place for this technique in 2049. As they write,

It can be seen that the velocity increment of the 2008EA9 is relatively small (-1.00km/s) and it will very close approach [approximately 645,000 miles] to the Earth in [February] 2049. Moreover the size of the NEO 2008EA9 is very small so that the capturing of it is relatively easy.

The real problem, of course, is adding that small “velocity increment” to the asteroid.

The Alarming Significance of Culture

The alarming significance of culture.

During a recent conversation with a close Jewish friend I asked him what he thought separated Jews from most other ethnic groups. I was expecting him to talk about how a shared history of oppression had strengthened Jews and brought them closer together. But his answer was both surprising and controversial. “Unlike gentiles, especially Christians,” he said, “Jews do not believe in an after life as such. There is no God up there dictating your lot in life. We don’t believe the meek shall inherit the earth. We truly believe in the power of an individual’s free will, guided of course by right principles.” [emphasis mine]

Cops confiscate cameras at Ohio Republican congressman’s town hall

Freedom of speech alert: Cops confiscate cameras at Ohio Republican congressman’s town hall. With video.

According to the cop on the video, he was following instructions from the Congressman. Either way, the cop should be fired for violating these citizen’s rights.

And it doesn’t matter if a Democrat or Republican does this. It is wrong, it is disgusting, and it is inexcusable. Such politicians should be kicked out of office immediately.

Progress freighter launch fails

The launch of a Progress freighter to ISS today has failed, with the freighter ending up crashing into Siberia.

This is very bad news for the station. Everyone in the space industry knows that with the shuttle gone, it will be a challenge to maintain supplies to the station’s the six-person crew. Losing just one supply ship will strain the station’s supplies, if not now in the long run for sure.

Worse, this is the first launch failure of the Soyuz rocket that puts both Progress and manned Soyuz capsule into orbit in more than eleven years. The next manned crew is scheduled for launch on September 21. Whether this failure will delay that launch remains unknown.

Budget Office: this year’s deficit to hit $1.28 Trillion

According to the Congressional Budget Office, this year’s deficit will be about $1.28 trillion, the third highest deficit in history, exceeded only by the previous two budgets of the Obama administration.

Note also that any cuts mentioned in the above article are not cuts, merely reductions in the overall growth of government. (Another example of a journalist lying for the government.) All told, the federal government will still continue to grow in the next few years at a pace that far exceeds inflation, the economy, or anything you can imagine in the real world.

NASA’s costs estimates too low for Congress’s heavy-lift rocket

Surprise, surprise! An independent analysis of NASA’s budget estimates to build Congress’s heavy-lift rocket, the program-formerly-called-Constellation, are untrustworthy and likely low.

“All three program estimates assume large, unsubstantiated, future cost efficiencies leading to the impression that they are optimistic,” the team said in its key findings. A risk assessment revealed the funding reserves projected for all three programs are insufficient, according to Booz Allen Hamilton. NASA has not disclosed its internal cost estimate for the Space Launch System. “Due to procurement of items still in development and large cost risks in the out years, NASA cannot have full confidence in the estimates for long-term planning,” the executive summary said.

This project is nothing more than Congressional pork. It will never get built. Sadly, it might waste a lot of money before it never gets built.

Earthquake in Virginia

Quake map

A 5.9 magnitude earthquake hit Virginia at about 1:51 pm (Eastern).

I am in Maryland, just outside the beltway, and felt something like an earthquake about five minutes ago. The house started to shake, then settled, then shook again. Quite startling. I opened the front door the same time a neighbor did. She had felt the same thing.

The above quake was more than 90 miles away. I wonder how bad it is there, considering the eastern U.S. rarely experiences quakes and has made no preparations for such a thing.

Bigelow in negotiations to supply privately-built modules to ISS

Bigelow Aerospace is in negotiations with both NASA and Japan to supply ISS with privately-built modules

The module could be rented out as an ISS storage unit, making the station less dependent on frequent resupply flights, says Hiroshi Kikuchi of JAMSS. To show that the modules are capable of safe, crewed operation, Bigelow is also negotiating with NASA to attach one to a US-owned ISS module.
