Mature galaxy cluster found in young universe

A mature galaxy cluster has been found by astronomers at a time when the universe is thought to be only a quarter of its present age.

This discovery could be very significant, since astronomers think mature galaxy clusters need time to form, and shouldn’t exist in the early universe. “If further observations find many more [of these clusters] then this may mean that our understanding of the early Universe needs to be revised.โ€

The icecaps of Greenland and Antarctica: are they melting?

NASA scientists have published a paper warning that there is growing evidence that the melting at the polar caps is accelerating. From the press release:

The pace at which the polar ice sheets are losing mass was found to be accelerating rapidly. Each year over the course of the study, the two ice sheets lost a combined average of 36.3 gigatonnes more than they did the year before. In comparison, the 2006 study of mountain glaciers and ice caps estimated their loss at 402 gigatonnes a year on average, with a year-over-year acceleration rate three times smaller than that of the ice sheets.

Several things to note after reading the actual paper:

Climate science hearing changes nothing

There was a hearing in Congress today on climate science, though it apparently changed nothing: the Republican leadership in the committee is going to proceed with legislation to try to roll back the EPA regulations relating to carbon dioxide imposed by the Obama administration.

The most interesting detail I gleaned from the above article however was this quote, written by the Science journalist himself, Eli Kintisch:

The hearing barely touched on the underlying issue, namely, is it appropriate for Congress to involve itself so deeply into the working of a regulatory agency? Are there precedents? And what are the legal and governance implications of curtailing an agency’s authority in this way?

What a strange thing to write. If I remember correctly, we are a democracy, and the people we elect to Congress are given the ultimate responsibility and authority to legislate. There are no “legal or governance implications.” If they want to rein in a regulatory agency, that is their absolute Constitutional right. That Kintisch and his editors at Science don’t seem to understand this basic fact about American governance is most astonishing.

Some detailed analysis by scientists of meteorite fossil paper

Here’s some detailed analysis by scientists of the meteorite fossil paper.

Once again, there is a great deal of skepticism, most of which appears reasonably and justified. Though a number of scientists have applauded his work, it really looks like Hoover does not have sufficient evidence to claim his samples are alien biology. However, this quote stands out:

It appears likely that Hoover’s study may soon be ignored by the majority of the scientific community, instead of enjoying a healthy debate such as that raised by McKay’s 1996 paper on the Mars meteorite. Redfield says that a microbiologist that she knows refused to read it. [emphasis mine]

That hardly seems the right response from an open-minded scientist.

More evidence Penn State’s investigation of Mann was a whitewash

More evidence that Penn State’s investigation of IPCC climate researcher Michael Mann was a whitewash.

The key point is that the Penn State investigators never interviewed a principal who was able to confirm or deny a key charge against โ€œHockey Stickโ€ lead author of โ€œHide the Declineโ€ infamy Michael Mann. This individual has now been interviewed, and what he told federal investigators has indicted Mann and Penn State.

I have noted this already, the very week the Penn State report was issued, but it is nice to see there is further evidence to confirm my conclusions.

A lean future for U.S. planetary missions

Planetary scientists make their recommendations for the kinds of planetary missions they think the United States should do for the next decade. And it looks like a lean future, as the scientists also note that their primary recommendations, missions to Mars and Europa, should only be built if their budgets can be trimmed significantly:

NASA’s top priority, according to the survey’s recommendations, should be the Mars Astrobiology Explorer Cacher, or MAX-C, which could help determine whether Mars ever supported life and offer insight on its geologic and climate history. It would also be the first step in an effort to get samples from Mars back to Earth. However, the report said this mission should only be undertaken if NASA’s cost is about $2.5 billion, which is $1 billion less than independent estimates provided to the panel. The mission would be run jointly by NASA and the European Space Agency, according to the survey.

A mission to Europa and its subsurface ocean — which might support life — should be the second priority mission, the experts said. But its estimated price tag of $4.7 billion may make it too expensive without an increase in NASA’s planetary science budget or a paring of the mission’s costs. [emphasis mine]

Planetary scientists reject meteorite fossil paper — without reading it

Richard Kerr of Science is attending the annual Lunar and Planetary Science Conference in Texas, and has written a short article describing the reaction of planetary scientists to the meteorite fossil paper by NASA scientist Richard Hoover. Their reaction, hostile and disinterested, isn’t pretty. These two quotes will give you the flavor:

Whether they have closely examined the paper by astrobiologist Richard Hoover of NASA’s Marshall Space Flight Center or only heard about it in the hallways, the reaction is the same: not again.

Rather than taking a look themselves, researchers have other things in mind. One leading scientist half-jokingly suggested hanging Hoover in effigy in the conference center lobby.

NASA Statement on Astrobiology Paper by Richard Hoover

In an unusual move, NASA has issued a statement on the alien fossil paper written by Richard Hoover. Key quote:

While we value the free exchange of ideas, data, and information as part of scientific and technical inquiry, NASA cannot stand behind or support a scientific claim unless it has been peer-reviewed or thoroughly examined by other qualified experts. This paper was submitted in 2007 to the International Journal of Astrobiology. However, the peer review process was not completed for that submission. NASA also was unaware of the recent submission of the paper to the Journal of Cosmology or of the paper’s subsequent publication.

This suggests that Hoover was having trouble getting published in one journal, and did an end-around to get published in a journal more agreeable to his conclusions.

Though this does raise questions about the validity of the research, it is always the research itself that matters. In this case I remain skeptical, but intrigued. I really would like to know why the peer-review process on Hoover’s paper was taking so long at the International Journal of Astrobiology. I would also love to read a critique of Hoover’s papers from scientists in the field.
