Astronomers found no radio signals from the comet that would suggest it is an extraterrestrial spacecraft. 3I/ATLAS was confirmed as the third known object to enter our solar system from interstellar ...

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.

In a stark deviation from what astronomers once believed about planetary systems, researchers have discovered that planets larger than Earth but smaller than Neptune are surprisingly common in the far ...

3I/ATLAS, an interstellar object whose unusual motion has ignited debate over possible artificial origins Astronomers are baffled by 3I/ATLAS, a newly discovered interstellar object that appears to be ...
