Hubble tracks the aftermath of a possible asteroid collision

Using the Hubble Space Telescope over the last ten months, astronomers have tracked the decaying aftermath of a possible asteroid collision. Key quote:

Astronomers think a smaller rock, perhaps 10 to 15 feet wide, slammed into the larger one. The pair probably collided at high speed, about 11,000 mph, which smashed and vaporized the small asteroid and stripped material from the larger one. Jewitt estimates that the violent encounter happened in February or March 2009 and was as powerful as the detonation of a small atomic bomb.

The image sequence below, taken from the original paper describing the discovery [pdf], shows the slow changes that have occurred since January. At the moment scientists do not have an satisfactory explanation for the nucleus’s X-shaped pattern in the earliest images.

We won’t release our contributors because the adminstration will then harass them

Is this how a government in a free society functions? The Chamber of Commerce won’t release its contributors because they fear the administration will harass and threaten them. And they have experience to back that fear up. Key quote:

What this administration wants is a list of who the companies are who are contributors, and we saw last year . . .when we very publicly ran ads against the Patients Protections and Affordable Care Act . . . there was an attempt to try and find out who were the corporations that were contributing to that effort. When some of those corporate names were divulged, not by us, by others, what did they receive? They received protests, they received threats, they were intimidated, they were harassed, they had to hire additional security, they were recipients of a host of proxies leveled at those companies that had nothing to do with the purpose of those companies. So we know what the purpose here is. It’s to harass and intimidate. [emphasis mine]

That the White House and President Obama are right now willing to accuse their opponents of all manner of evils (taking money from foreign governments) without any evidence is further evidence that there are reasons to fear them.

MTV Denies That Obama Telecast Is Political

How stupid do they really think people are? MTV and Viacom deny that a one hour Obama telecast only three weeks before the election, A Conversation with President Obama, is not political and does not require them to give equal time to Republicans. Note that the White House came up with the idea, and that the audience is being pre-screened in advance.
