For the better part of a century, we believed there were nine planets in our solar system, with Pluto being the farthest from the sun. Since the discovery of more Pluto-sized dwarf planets, that ...

For the first time, NASA’s James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles, often originating from the Sun, become trapped in a ...

Astronomers have tracked several meteorites that dropped in on Earth back to their origin, space rocks in the main asteroid belt between Mars and Jupiter.

The findings provide strong evidence that four giant exoplanets 130 light-years from Earth formed much like Jupiter and ...
