Take a close look at the stunning image above showing a newly formed impact crater on Mars: The blue streaks of material, known as ejecta, radiate 9 miles from the 100-foot crater, according to NASA.
The picture was taken from orbit by the Mars Reconnaissance Orbiter on Nov. 19. The same area was imaged by the MRO's Context Camera in July 2010 and again in May 2012 — with no crater in the first and a telltale surface scar in the second.
Parliament in London is an old-fashioned place. When members gather in the House of Commons, the sea of faces is generally wrinkled, white and male.

Aston Martin, James Bond's conveyance of choice, has expanded its recall of vehicles built since 2007 because of problems with fake plastics from China.
In a letter last month to the National Highway Transportation Safety Administration, Aston Martin said it had received reports that throttle pedal arms broke during installation, and it discovered that "initial tests on the failed pedal arm have shown that the Tier Three Supplier used counterfeit material."
If you don't know the meaning of a word, says Mary Caton Lingold, you can look it up in the dictionary, but if you don't know what a particular sound sounds like, where do you go? (Besides NPR, of course.)

The teenage years are a tumultuous time, with about 11 percent developing depression by age 18. Lack of sleep may increase teenagers' risk of depression, two studies say.
Teenagers who don't get enough sleep are four times as likely to develop major depressive disorder as their peers who sleep more, according to researchers at the University of Texas Health Science Center in Houston. They tracked the habits of more than 4,000 adolescents over a year.
