When stars explode as supernovas, they can cause serious cosmic carnage. Is Earth in any danger from any nearby stars?

A new model based on the famous alien-hunting Drake equation suggests that some parallel universes within the hypothetical "multiverse" could have higher chances of containing extraterrestrial life than our universe.

From nebulas and black holes to baby star nurseries and ancient collisions, the universe has never looked more beautiful thanks to NASA's $10 billion-telescope.

Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen gravitational triad. The system's unique configuration suggests that the black hole was not created as scientists initially expected.

Some of the earliest galaxies found with JWST are also the brightest. That's a problem for our ideas about the universe.

Using the Gaia space telescope, astronomers have observed 55 massive stars ejected from their home star cluster in the Large Magellanic Cloud at speeds equivalent to 80 times the speed of sound.

The Dark Energy Camera imaged the Rosette Nebula, capturing a kaleidoscope of color created by the star cluster born within it.

Using NASA's exoplanet-hunting spacecraft, TESS, astronomers and citizen scientists have discovered a record-breaking system of three tightly bound stars that could fit between the sun and Mercury.
