The Earth "changes the colour" of asteroids by shaking them up as they pass, according to scientists. Researchers report that this solves the mystery of why the meteorites that land on the Earth often do not match the colour of asteroids in space...

A large space rock may have exploded over Antarctica thousands of years ago, showering a large area with debris, according to new research. The evidence comes from accumulations of tiny meteoritic particles and a layer of extraterrestrial dust found in Antarctic ice cores.

There is now even more evidence that life on Earth may have been seeded by material from asteroids or comets. Prior research has shown how amino acids - the building blocks of life - could form elsewhere in the cosmos. These molecules can form in two versions, but life on Earth exclusively uses just one of them. Now an Astrophysical Journal Letters paper shows how conditions around a far-flung star could favour the formation of one type...

A meteorite found in Antarctica could lend weight to the argument that life on Earth might have been kick-started from space, scientists are claiming. Chemical analysis of the meteorite shows it to be rich in the gas ammonia. It contains the element nitrogen, found in the proteins and DNA that form the basis of life as we know it.
