New Southwest Research Institute-led modeling indicates the main belt asteroid (52246) Donaldjohanson may have formed about 150 million years ago when a larger parent asteroid broke apart; its orbit ...

"We now have the first outlines of a geologic map of the asteroid belt." Ten years ago, Jenniskens teamed up with astronomer Hadrien Devillepoix of Curtin University and colleagues in Australia to ...

"This has been a decade-long detective story, with each recorded meteorite fall providing a new clue," said one astronomer.

In a review paper, astronomers trace the impact orbit of observed meteorite falls to several previously unidentified source regions in the asteroid belt. Where do meteorites of different type come ...
