Year: 2011

The first observations of a star, just prior to going supernova

1:30 pm

Astronomers have for the first time observed the changes that took place in a binary star system in the years before one star in the system erupted as a supernova.

In the first survey of its kind, the researchers have been scanning 25 nearby galaxies for stars that brighten and dim in unusual ways, in order to catch a few that are about to meet their end. In the three years since the study began, this particular unnamed binary system in the Whirlpool Galaxy was the first among the stars they’ve cataloged to produce a supernova.

The astronomers were trying to find out if there are patterns of brightening or dimming that herald the end of a star’s life. Instead, they saw one star in this binary system dim noticeably before the other one exploded in a supernova during the summer of 2011.

Key quote: “Our underlying goal is to look for any kind of signature behavior that will enable us to identify stars before they explode,”

The supernova in question, 2011dh, was the closest supernova in decades, occurring in June 2011 in the Whirlpool Galaxy (M51). See my previous posts here and here.

A new Rasmussen national poll: Gingrich 45% Obama 43%

A new Rasmussen national poll: Gingrich 45% Obama 43%.

Last week, Gingrich trailed the president by six. Two weeks ago, he was down by twelve. Earlier in the year, both Rick Perry and Herman Cain followed a similar path to take a slight lead over the president. However, in both cases, their time as frontrunners quickly came to an end. Neither man led the president more than a single time in a Rasmussen Reports poll. It remains to be seen whether Gingrich follows that path or is able to retain his status as the leading alternative to former Massachusetts Governor Mitt Romney.

Note that every candidate has polled ahead of Obama at one time or another, suggesting to me that the public wants Obama out, and is fishing for the candidate to do it.

Weather, not climate

10:35 am

From Walter Russell Mead: Weather, not climate.

Those Via Meadia readers old enough to remember Hurricane Katrina can no doubt remember the many moralizing predictions of smug and condescending green climate hacktivists that followed: global warming was going to mean more hurricanes and bigger ones. Our coasts were toast; it was baked in the cake. The rising sea level combined with the inexorably rising number of major hurricanes were going to knock the climate skeptics out of the park.

Well, no. Andrew Revkin has called attention to this post from Roger Pielke’s blog which shows that as of today it has been 2,226 days since the last major hurricane (Category 3 or higher) hit the US mainland. Unless a big hurricane hits this winter, it means we are on track to break a 100 year record for the longest gap between major hurricanes hitting the coast. (The last Big Calm was between 1900 and 1906.) [emphasis mine]

Canada has joined the United States in raising objections to a planned $100-billion a year climate fund

12:48 am

The gravy train is ending: Canada has joined the United States in raising objections to a planned $100-billion a year climate fund.

I like this quote describing the U.S.’s objections:

Heading into the United Nations climate conference in Durban this week, the United States has made it clear it will not support the current proposals for the climate fund over concerns about how the money would be raised, lack of verification of how it is spent, and an unwillingness of major emerging countries to commit to legally binding emissions reduction. [emphasis mine]

Other than these minor points, everything about the fund is above board and legitimate.

Despite earmark ban, some lawmakers continue to try to give money to hundreds of pet projects

11:06 pm

The battle over earmarks.

The efforts to resurrect spending on pet projects reveal the tenuous nature of current reform efforts. Two senators have publicly called out their colleagues and will introduce legislation Wednesday that would ban earmarking with the force of law. “I have heard too many appropriators say informally that they are very hopeful that we can get back to earmarking in the future with few restrictions,” said Sen. Claire McCaskill (D-Mo.), who is co-authoring the bill with Sen. Patrick J. Toomey (R-Pa.). “That has come out of the mouths of Democrats and Republicans.”

What I glean from this article is that a good number of legislators are still trying to sneak in their earmarks, but that they are finding it increasingly difficult. Unfortunately, it also appears that too many of them are still succeeding.
