Physicists have analyzed two enormous black hole mergers that happened one month apart and have come up with tantalizing evidence that rare "second-generation" black holes were involved.

Interstellar comet 3I/ATLAS is briefly out of view as it travels around the sun this week, but researchers and amateur astronomers used spacecraft data to track its progress right up until perihelion.

Researchers armed with a new "photonic lantern" device have discovered an unexpectedly asymmetrical disk of gas swirling around a mysterious star 162 light-years from Earth. The new technology could revolutionize ground-based astronomy, the researchers claim.

New ESA simulations suggest that a solar storm on par with the 1859 Carrington Event could wreak havoc on Earth-orbiting satellites — and it is a question of "when," not "if" this will happen, experts say.

Scientists have spotted elusive "magnetic waves" in the sun's atmosphere that may explain why the sun's corona is much hotter than its surface.

New observations from the James Webb Space Telescope have uncovered five complex organic molecules trapped in the ice around a star outside our galaxy. This cosmic first hints that the stuff of life may be widespread throughout space.

An astronomer in Italy caught a fortuitous image of the bright comet Lemmon seemingly entwined with the glowing trail of a "shooting star."

While scouring images from the James Webb Space Telescope, astronomers spotted Capotauro, "one of the most puzzling discoveries" to date.

Astronomers have found signs that the small icy world Chiron, orbiting between Saturn and Uranus, may be forming a new ring system in near-real time.
