The widely talked about Comet 3I/ATLAS will pass by the sun on Thursday, but it will be December before stargazers can get a glimpse of the object.

A distant gas giant the size of 10 Jupiters is now the first planet outside Earth's solar system to be mapped in three dimensions.

Researchers rarely get a glimpse of an interstellar object up close like 3I-ATLAS, so they have jumped on the opportunity to learn about its composition, which can reveal how planet systems are made.

The comet – named 3I/ ATLAS – was discovered this summer and led to excitement because it appears to be an interstellar comet, which has made its way to us from another solar system. It is only the third visitor of its kind, and this time scientists have been able to track its journey and study its characteristics in particular detail.

The James Webb Telescope captures the beginning of planetary formation around the young star HOPS-315 for the first time.

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and Earth. The authors dubbed it Planet Y.
