New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder to detect.

Comets are often treated as leftovers, but sometimes the leftovers become the primary focus. That is the case with 3I/ATLAS, only the third known interstellar object seen crossing the solar system, ...

What can a piece of debris from another star tell astronomers about planets they may never see directly? The answer has changed dramatically since the first confirmed object from another star crossed ...

Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to detect.

The first bubble of hot gas seen around another star has been spotted around the "Moth," just 117 light-years away.

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 ...

Object 3I/ATLAS is now too far from Earth to aim a telescope at, but prior observations showed some unusual behavior. The anomalous nature of the object led astrophysicist Avi Loeb to apply a thought ...

Remember 3I/ATLAS? Yes, the interstellar comet that made plenty of headlines in 2025 is still romping through our solar system.
