A nearby galaxy is undergoing a major transformation, and astronomers are watching the process unfold in real time ...

Astronomers trace the Small Magellanic Cloud’s unusual stellar motions to a past cosmic encounter.

T he first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. It was 2018, and the discovery had just ...

The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors—a small, gas-rich galaxy visible to the ...

The Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors, is undergoing a transformation visible from the southern hemisphere. This change is due ...

Galaxies carry the imprints of past encounters. When they pass near one another or collide, gravity pulls their stars into ...

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

Astronomers detect a laser-like signal coming from colliding galaxies 8 billion light-years away. A cosmic mystery.

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

The violent collision of two neutron stars is providing new insights on how the universe’s heaviest elements were created.

Despite years of debate and follow-up studies, an odd streak of cosmic light still defies a final explanation. Is it a giant ...

Astronomers have collected evidence of a violent collision between two planets in a distant star system. The first clues of this cataclysmic event came when a rather boring star began behaving very ...
