Space object which wiped out the dinosaurs 65 million years ago, it might be a comet impact, not an asteroid, a new study indicates.

180-kilometer Chicxulub crater, located in Mexico, was established as a result of the collision, which led to the extinction of the dinosaurs and about 70 percent of all species on earth, according to many scientists.

The spacecraft for the collision of an asteroid in 2022


Scientists from Europe and the U.S. to confidently move promote in their plans to make a deliberate collision of a spacecraft with a giant asteroid in 2022 to look into the depths of such visitations.

Ambitious European mission Asteroid Impact and Deflection Assessment, or AIDA, consisting of two satellites (one of which will be built by scientists from the U.S., and the second - the European Space Agency), is scheduled to start a three-year journey to the asteroid Didymus and his companion. Didim not dangerous for the Earth, so it is well suited for this kind of research, scientists said the mission at the 44th Annual Conference of the moon and planets, on Tuesday, March 19.

MESSENGER sees the smooth side of Mercury


During the two years of its location in orbit around Mercury, NASA's MESSENGER spacecraft has made ​​more than 150,000 images of the planet closest to the Sun, the solar system, first giving us the opportunity to think about the extremely rough, parched surface of the planet in feature. But not all areas on Mercury look stern and sinister: it also has a smooth side, you can see on the picture, published today.
