The comet formed in a cold and distant part of the early Milky Way up to 12 billion years ago, putting it just under 2 ...

Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising ...

Two powerful instruments of the NASA/ESA/CSA James Webb Space Telescope joined forces to create this scenic galaxy view. This spiral galaxy is named NGC 5134, and it is located 65 million light-years ...

At roughly 250,000 kilometers per hour, comet 3I/ATLAS did not merely enter the inner solar system; it tore through it at a ...

Webb has captured the haunting “Exposed Cranium” nebula—an otherworldly cloud shaped by a dying star that looks remarkably like a brain inside a skull.

The Gaia telescope spotted more than 6,000 sunlike stars, all of which appear to have migrated from the galaxy's center more than 4 billion years ago.

Our sun and a host of "solar twins" may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.

An object older than the solar system is crossing familiar planetary territory, and spacecraft built for entirely different missions are turning into a makeshift deep-space observatory to study it.
