The atmosphere of Earth during the Mesozoic era, between 252 and 66 million years ago, contained far more carbon dioxide than it does today and total photosynthesis...
The first bodies to form in the Solar System acquired their materials from stars, the presolar molecular cloud and the protoplanetary disk. Asteroids that...
The previously unknown nucleus aluminum-20 has been observed for the first time by detecting its in-flight decays.
