Astronomers have just uncovered a giant cavity in our galaxy, and it was hiding in plain sight. Sitting between the Taurus and Perseus molecular clouds, this 500-light-year-wide bubble was long ...

Astronomers have captured the clearest picture yet of how massive stars are born, revealing a dramatic interplay between ...

SN2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its ...

In a galaxy some 450 million light-years away, a brilliant flare of light revealed a probable black hole that suddenly woke from its slumber to snack on a passing star. This is not, in itself, a ...

Hubble has helped uncover a white dwarf that’s likely the result of two stars crashing together. Carbon traces in its atmosphere tell a story of a cosmic merger, a rare phenomenon previously invisible ...

Astronomers have seen a lot of stars explode, but one unusual stellar death is forcing them to rethink what they thought they knew. In 2021, a star about 2.2 billion light-years away ended its life in ...

A new peer-reviewed study finds that early planet formations were assembled from fragments of earlier bodies within the Solar System.

The discovery of a rare runaway galaxy suggests some isolated systems were shaped by past group interactions before being flung into solitude.

Astronomers observed something incredible in a region that not much was expecting—a planet-scale object drifting alone in ...

This massive star-forming cloud is working surprisingly fast. A maelstrom of star formation close to the center of our galaxy has been revealed in two different wavelengths by the James Webb Space ...
