This long exposure picture of a tiny patch of sky in the constellation Fornax spotted about 5,500 galaxies from the very beginning of the universe. Take a close look, because you will see that these early galaxies are often strange looking. I have cropped out one just example to the left to give you an idea.
The next great comet?
Amateur astronomer Jason Lewis sent me an email today describing how the amateur astronomy community is abuzz with the discovery of a new comet, presently dubbed C/2012 S1, that is due to make its dive around the Sun in late November 2013 and pass closest to the Earth in January 2014 at a distance of about 37 million miles. Based on the preliminary numbers, this comet might be one of the brightest in years, almost certainly a naked eye object and visible to everyone from both the northern and southern hemispheres.
To quote the comments from one astronomy forum:

Astronomers using the Chandra X-Ray Observatory have found that the Milky Way is surrounded by a halo of hot gas.The uncertainty of science: Astronomers using the Chandra X-Ray Observatory have found that the Milky Way is surrounded by a halo of hot gas.
The uncertainty of science: Astronomers using the Chandra X-Ray Observatory have found that the Milky Way is surrounded by a halo of hot gas.
This is the key quote:
The estimated mass of the halo is comparable to the mass of all the stars in the galaxy. If the size and mass of this gas halo is confirmed, it also could be an explanation for what is known as the “missing baryon” problem for the galaxy.
“Missing baryon” is another way to say “dark matter.” In other words, this discovery might prove that it isn’t necessary to invent exotic unknown particles of physics, such as the Weakly Interacting Massive Particles (WIMPs) to explain the missing matter. The missing matter might simply be this hot gas, previously undetected.

I especially like the research where scientists performed MRI brain scans on pumpkins, Cornish hens, and dead fish. And they even got a signal from the dead fish!
Newly released results from Dawn have found evidence of hydrogen on the surface of Vesta
Newly released results from Dawn have found evidence of hydrogen on the surface of Vesta, which also suggests that the asteroid once had water. More here.
The article focuses on the possibility that the hydrogen originally came from ice placed there by icy asteroids. While likely, this remains only one possible explanation.
Hundreds of peer-reviewed papers in the field of anaesthesiology are about to be retracted because their data was fabricated.
Hundreds of peer-reviewed papers in the field of anesthesiology are about to be retracted because their data was fabricated.
After more than a decade of suspicion about the work of anesthesiologist Yoshitaka Fujii, formerly of Toho University in Tokyo, investigations by journals and universities have concluded that he fabricated data on an epic scale. At least half of the roughly 200 papers he authored on responses to drugs after surgery are in line for retraction in the coming months.
Like many cases of fraud, this one has raised questions about how the misconduct went undetected for so long. But the scope and duration of Fujii’s deception have shaken multiple journals and the entire field of anesthesiology, which has seen other high-profile frauds in the past few years.
Fujii’s work was published in many different journals, where it appears none of his referees ever checked his data. Worse, this is not the first such case in this field.

After postponing Juno’s second midcourse correction burn, engineers have now successfully completed that burn.
After postponing Juno’s second midcourse correction burn last month, engineers have now successfully completed that burn.
NASA’s Juno spacecraft successfully executed a second Deep Space Maneuver, called DSM-2 last Friday, Sept. 14. The 30 minute firing of its main engine refined the Jupiter-bound spacecraft’s trajectory, setting the stage for a gravity assist from a flyby of Earth on Oct 9, 2013. Juno will arrive at Jupiter on July 4, 2016.

Weird Planet fractals
An evening pause: There is really a very thin line between math and life.
The scientists who took the first image of single molecule in 2009 have improved the resolution of their images.

They not only can see the molecule, they can now detect the differences between the atomic bonds holding the different atoms together.
The first results from the two GRAIL space probes have revealed the Moon has a much thinner crust than previously believed.
The uncertainty of science: The first results from the two GRAIL space probes have revealed that the Moon has a much thinner crust than previously believed.
These preliminary results have also found that the Moon’s surface topography closely matched the variations in the gravitational field, and that there appears no evidence in the gravitational field of the giant ancient impact basins that scientists have for decades assumed were there, based on surface evidence. This last result is especially surprising, and will force an almost complete rewrite of the Moon’s geological history.
Interestingly, these results are only peripherally related to GRAIL’s main research goal, which was to map the Moon’s deep structure and core. I suspect there are even more surprises coming when this data gets released.
The science cuts from sequestration
The journal Science today published this detailed look at the cuts that would occur in all the federal government’s various science programs should the automatic budget cuts outlined in the sequestration legislation occur on January 2, 2013.
Not surprising, the article includes a great deal of moaning and groaning about the terrible harm the cuts would have on science research should they occur. From the Obama administration:

A new and very large study now suggests that — even though no one really knows why — acupuncture might actually be effective.
The uncertainty of science: A new and very large study now suggests that — even though no one really knows why — acupuncture might actually be effective.
The key mystery here is the lack of any explanation for why acupuncture seems to work. And without that explanation, a large number of doctors will justifiable still refuse to use it as a course of treatment.
