There’s a visitor in town, and its name is 3I/ATLAS. The presumed interstellar comet presents a rare opportunity for astronomers to study an object born a long time ago in a star system far, far away.

Scientists say the colour shift in interstellar comet 3I/ATLAS is due to gases in the comet's coma reacting to solar heat.

The interstellar comet 3I/ATLAS is just days away from coming as close to Earth as it will ever get. Here's how you can track ...

Astronomers have been scanning the skies for alien radio signals for decades, but so far they’ve heard nary a peep (with one possible exception). But according to a recent study, that could be because ...

At 150 light-years from Earth, the Hyades cluster is the nearest star cluster to Earth's solar system and scientists have long wondered if some of those stars are home to alien planets. Now, that ...

Peering through a cosmic keyhole at distant baby star, astronomers may have opened a new window on the deep past of our own solar system. Weighing in at 0.6 solar mass, HOPS-315 should someday grow to ...
