The surface of Mars is a well worn place in the Solar System, heavily pounded by countless meteor impacts. And some of these craters are hundreds of millions of years old. So it’s unusual for there to be a completely fresh impact on the surface of Mars: but that’s just what NASA scientists discovered looking through a recent batch of images returned from NASA’s Mars Reconnaissance Orbiter.

You’re looking at a composite of two images taken by the Mars Context Camera, an instrument on board the Mars Reconnaissance Orbiter the most recnt one on the right and an older photograph taken of the same region in February 2012 on the left. On the older one there was just a bunch of old craters. And then, in the newer image, taken June 2014, this fresh scar on the surface of Mars is clearly visible. (learn more)

Biggest metor impact on the Moon recorded.

The University of Huelva has released (see above) images of the high-speed impact of a wayward space rock on the surface of the moon last year triggered the brightest lunar explosion ever seen, scientists say.

Video footage of the record-breaking meteorite strike on the moon, which occurred on Sept. 11, 2013 and was unveiled today (Feb. 24), shows a long flash that was almost as bright as the North Star Polaris. That means the boulder-sized meteorite's lunar crash could have been visible to anyone on Earth who happened to be staring up at the moon at 8:07 p.m. GMT, weather permitting.

The following video is a simulation of the chain of events that leaded to the impact.

Scientists Find New Type of Mineral in Historic Meteorite

NASA and co-researchers from the United States, South Korea and Japan have found a new mineral named "Wassonite" in one of the most historically significant meteorites recovered in Antarctica in December 1969.

The new mineral was discovered within the meteorite officially designated Yamato 691 enstatite chondrite. The meteorite was discovered the same year as other landmark meteorites Allende and Murchison and the return of the first Apollo lunar samples. The study of meteorites helps define our understanding of the formation and history of the solar system. (read more)
