Astronomers have ruled out alien origins for interstellar visitor 3I/ATLAS, confirming it's a natural comet--not an extraterrestrial spacecraft--while revealing clues about its ancient birthplace beyond the solar system.

Some of the earliest images ever taken in the wake of massive star's death give astronomers important clues about what triggers a supernova.

Interstellar comet 3I/ATLAS is glowing brighter and defying all cometary science. Astronomers are baffled by its intense energy and unique chemical signature, suggesting this visitor is not a typical icy body.

When an asteroid threatens Earth, astronomers use a rating called the Torino scale to communicate the risk. Richard Binzel, who invented the scale, tells New Scientist about his 50-year career in planetary defence ...

Astronomers detected the first radio signal from 3I/ATLAS (natural hydroxyl confirmed). Discover the low-latitude impact danger zones and follow the upcoming Juno observation.

The shimmering Pleiades star cluster has just shed its millennia-old reputation as a collection of Seven Sisters. Thanks to new data gleaned from the TESS and Gaia star-tracking spacecrafts, astronomers have revealed that this iconic group is part of ...

The mysterious object feared to be an alien space craft as it flies through space at mega speed has sent its first radio wave signals, but boffins believe there's a clear reason behind it ...

Astronomers using the James Webb Space Telescope have uncovered a trove of complex organic molecules frozen in ice around a young star in a neighboring galaxy -- including the first-ever detection of acetic acid beyond the Milky Way. Found in the ...

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars -- a first in astronomy. The system's compact, cold nature defies conventional theories of planetary ...
