Billions of light years away in a remote part of the universe, two neutron stars—the ultradense remnants of dead stars—collided. The catastrophic cosmic event sent light and particles, including a ...

Neutron star collision in merging galaxies reveals how cosmic destruction forges heavy elements like gold, offering clues to the universe's chemical evolution.

How is it that galaxies merge and collide but the universe is expanding and everything is moving away from everything else? Justin HammersleySterling Heights, Michigan Whether or not galaxies merge ...

The James Webb Space Telescope has peered through cosmic dust to reveal new details and a stunning image of a rare type of galaxy. The space observatory's latest image shows the Cartwheel galaxy, a ...

Looking ahead: Future Euclid observations will enable scientists to watch how galaxy collisions spark bursts of star formation, fuel shrouded black holes, and unleash energetic feedback. According to ...

Astronomers used AI to search 35 years of Hubble data and discovered over 1,300 rare cosmic anomalies hidden in plain sight.

NASA’s James Webb Space Telescope (JWST) has captured images of a distant galaxy that is forming a peculiar cosmic structure resembling a question mark. This observation, revealed in a study published ...

Scientists have long thought the Milky Way galaxy would someday collide with its closest neighbor, Andromeda. However, new research suggests the future of our cosmic home is more uncertain than ...

A 50-million-light-year-long flow of hydrogen gas has been observed linking two tiny galaxies 50 million light-years away, giving astronomers a spectacular view of how galaxies attract, warp, and ...

A strange line of dwarf galaxies may have been the result of a bullet-like cosmic collision. Michael Keim at Yale University and his colleagues used the Keck Observatory in Hawaii to study a unique ...

Using early data from the European Space Agency’s Euclid space telescope, astronomers have analyzed over one million galaxies to test a long-standing idea in astrophysics: that galaxy mergers help ...
