Ever since scientists started looking at meteorites with microscopes, they’ve been puzzled–and fascinated–by what’s inside. Most meteorites are made of tiny beads of glass that date back to the ...

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

Astronomers might have found evidence of a structure located farbeyond Neptune, potentially giving us clues about the solar system’s primordial past. This discovery involves a dense concentration of ...

"During the early solar system's game of cosmic billiards, Earth was struck by a neighbor,” said Dauphas. “It was a lucky shot. Without the moon's steadying influence on our planet's tilt, the climate ...

Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered ...

Moon’s precursor planet, Theia, disappeared billions ago, leaving scientists no direct chemical evidence to support the hypothesis. Now a team of astromers in France, Germany and the United States ...

Pluto hasn't been a planet for almost 20 years. In the early 2000s, scientists discovered several objects of a similar size to Pluto. So, during the summer of 2006, members of the International ...
