The location of the volcanoes on Titan are not where scientists had expected them to be.
The uncertainty of science: The location of the volcanoes on Titan are not where scientists had expected them to be.
As Io moves closer to Jupiter, the planet’s powerful gravity pulls hard on the moon, deforming it. This force decreases as Io retreats, and the moon bounces back. This cycle of flexing creates friction in Io’s interior, which in turn generates enormous amounts of volcano-driving tidal heat. Common sense suggests that Io’s volcanoes would be located above the spots with the most dramatic internal heating. But Hamilton and his colleagues found that the volcanoes are significantly farther to the east than expected.
Many of the news headlines, including the article above, have trumpeted how the volcanoes on Io are in the wrong place. (See also this article.) Not. The theories were wrong, not the volcanoes. Nature does what it wants to do. It is our job to figure out why.

Using Hubble astronomers have confirmed that it was a yellow supergiant star that was the progenitor for the nearest supernovae in decades that occurred in 2011.
Using Hubble astronomers have confirmed that it was a yellow supergiant star that was the progenitor for the nearest supernovae in decades, that occurred in 2011 in the Whirlpool Galaxy.
The uncertainty of science: As I noted in 2011 when the yellow supergiant was first detected in pre-explosion images. no theory at that time had ever proposed this kind of star as a supernova progenitor. The discovery has thus required the theorists to come up with new theories.

The scientists who attempted to re-invent Michael Mann’s hockey stick global warming graph and were caught fudging their data have admitted their data is worthless
The scientists who attempted to re-invent Michael Mann’s hockey stick global warming graph and were caught fudging their data have essentially admitted that their data is worthless.
This is what they say in a FAQ they have added to their paper:
Q: What do paleotemperature reconstructions show about the temperature of the last 100 years?
A: Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the 20th century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used. Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions. [emphasis mine]
They are basically admitting that the data used to create the temperature rise of their hockey stick during the past 100 years is unreliable and therefore useless for scientific purposes. Which raises the question: Why did they publish it in the first place? See especially this analysis of this paper and the press’s reaction to it by climate scientists Roger Pielke.

North Korea says it has authorized plans for nuclear strikes against the United States.
Bad: North Korea says it has authorized plans for a nuclear strike against the United States.
But, while Pyongyang has successfully carried out test nuclear detonations, most experts think it is not yet capable of mounting a device on a ballistic missile capable of striking US bases or territory. Mounting tension in the region could however trigger incidents on the tense and heavily-militarised border between North and South Korea. There was no immediate American reaction to the North’s latest statement, but US Defense Secretary Chuck Hagel said Pyongyang represented a “real and clear danger” to the United States and to its allies South Korea and Japan. [emphasis mine]
Right now North Korea almost certainly cannot hit the U.S. with an ICBM. However, South Korea and Japan are very very very exposed.

“The SLS program should be canceled now to free up approximately $10 billion programmed for this decade.”
I’m both glad and not surprised that some heavy hitters are beginning to say this. As I noted last year, as the commercial space program begins to show success the politics will increasingly favor it over the very expensive and not very productive NASA-built Space Launch System.
Be prepared for SLS to steadily lose political support in the coming years.

An audit of California’s fiscal state has found it to be $127 billion in the red.
The day of reckoning looms: An audit of California’s fiscal state has found it to be $127 billion in the red.
Were California’s state government a business, it would be a candidate for insolvency with a negative net worth of $127.2 billion, according to an annual financial report issued by State Auditor Elaine Howle and the Bureau of State Audits. The report, which covers the fiscal year ending June 30, 2012, says that the state’s negative status — all of its assets minus all of its liabilities — increased that year, largely because it spent more than it received in revenue. [emphasis mine]
None of this is a surprise. California voters chose Jerry Brown and the Democrats to lead them into more debt.

Astronomers watch the central supermassive black hole of a galaxy eat something, either a planet or a brown dwarf.
Astronomers watch the central supermassive black hole of a galaxy eat something, either a planet or a brown dwarf.
Astronomers were using Integral to study a different galaxy when they noticed a bright X-ray flare coming from another location in the same wide field-of-view. Using XMM-Newton, the origin was confirmed as NGC 4845, a galaxy never before detected at high energies. Along with Swift and MAXI, the emission was traced from its maximum in January 2011, when the galaxy brightened by a factor of a thousand, and then as it subsided over the course of the year. “The observation was completely unexpected, from a galaxy that has been quiet for at least 20–30 years,” says Marek Nikolajuk of the University of Bialystok, Poland, lead author of the paper in Astronomy & Astrophysics.
By analysing the characteristics of the flare, the astronomers could determine that the emission came from a halo of material around the galaxy’s central black hole as it tore apart and fed on an object of 14–30 Jupiter masses. This size range corresponds to brown dwarfs, substellar objects that are not massive enough to fuse hydrogen in their core and ignite as stars. However, the authors note that it could have had an even lower mass, just a few times that of Jupiter, placing it in the range of gas-giant planets.
