An all-new meteor shower makes its debut tonight, and astronomers say it could put on a show starting as early as 10:30 p.m. ET Friday and peaking early Saturday. Called the Camelopardalids, the shower is named after the giraffe constellation. It's expected to be visible in nearly all of the U.S., if skies are clear.

"No one has seen it before," NASA says, "but the shower could put on a show that would rival the prolific Perseid meteor shower in August."

Before and after shots taken by a Mars-orbiting satellite have detected a newly created impact crater half the size of a football field near the planet's equator.

NPR's Joe Palca says that while objects are striking Mars all the time (with big chunks surviving until impact, thanks to the Red Planet's thin atmosphere), this is the first time scientists have been able to determine the exact day a meteor struck – in this case, sometime on March 28, 2012.
