This mission follows NASA’s Psyche spacecraft on its journey to a rare metal-rich asteroid, believed to be the exposed core ...

In Earth's early days, it was slammed by protoplanet Theia. This left our world spinning on a tilted axis. But what if the ...

Bennu is believed to have originated from the shards of a much larger world. Curiously, asteroid Ryugu, sampled by the ...

Earth may not have to look quite so far for its moon because when our young planet was in a catastrophic collision with a ...

Did you know that there are actually two different sets of seasons, and thus two different winters, every year?

Apollo samples provide evidence: Researchers analyzed Moon rocks brought back by the Apollo missions and, for the first time, ...

The Moon is getting 1½ inches (3.8 centimeters) farther away from the Earth every year. Scientists measure the distance to ...

The giant protoplanet Theia, which collided with Earth 4.5 billion years ago, originated from the inner solar system and likely formed closer to the sun than Earth. This was discovered by a research ...

A collision between Earth and a massive Mars-sized protoplanet likely caused the formation of our moon. Now scientists from the Max Planck Institute suggest that doomed planet was likely a rowdy ...

Proto-Earth is the term used to describe the earliest days of our planet, the body from which our pale blue dot evolved. At this stage of its geological evolution, it likely existed only for a ...

Dust particles spotted around a young star support an idea about how planets are born. Planet formation is a paradox: according to standard theory, dust grains orbiting newborn stars should spiral ...

Researchers have discovered a young protoplanet called WISPIT 2b embedded in a ring-shaped gap in a disk encircling a young star. While theorists have thought that planets likely exist in these gaps ...
