New research investigates how relativistic jets from a supermassive black hole has been shaping the Teacup Galaxy, giving it its iconic handle.

Astronomers have discovered several fascinating features in galaxy cluster Abell 1213 such as a central galaxy with a 1.66 million light-year-long radio "tail" and remains of galactic mergers.

Even quiet red dwarfs are prone to extreme outbursts that put our sun to shame, with significant implications on the search for alien life.

An image from the Hubble Space Telescope captures an irregular spiral galaxy known as NGC 5486, which lies close to the much larger and well-known Pinwheel Galaxy.

New James Webb Space Telescope observations reveal that the galaxy GS-9209 had its star-forming power abruptly “quenched” by mysterious forces after millions of years of productivity.

When the universe's first stars emerged from the cosmic dark ages, they ballooned to 10,000 times the mass of Earth's sun, new research suggests.

The James Webb Space Telescope (JWST) has dazzled us plenty already, but the best is yet to come from the observatory, mission team members say.
