Comet 3I/ATLAS was first identified by the Asteroid Terrestrial-impact Last Alert System (ATLAS), a global network of four ...

Astronomers have, for the first time, captured what they believe are the very first moments of rocky planet formation around ...

A young sunlike star called HOPS 315 seems to host a swirling disk of gas giving rise to minerals that kick-start the planet formation process.

Discover 3I/ATLAS, an interstellar comet with a reddish hue, rich in water ice, and possibly predating the solar system.

Billions of years ago, in the frozen edges of the solar system, a violent impact shaped one of space’s oddest pairs. Instead of a typical planet-moon setup, Pluto and Charon became a binary system.

There’s a giant ball of ice barreling through the solar system right now, and it’s bigger than any we’ve seen before. It poses no threat to Earth, but this comet, called C/2014 UN271 ...

The sun will reach solar maximum, or a peak in activity across its 11-year cycle, about a year sooner than originally predicted. Auroras, solar flares and space weather are all expected to increase.

The mystery of our solar system’s missing super-Earths and sub-Neptunes is not yet solved. Studying these exoplanets is one of NASA’s top priorities and JWST plays a pivotal role.
