Our sun and a host of "solar twins" may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.

Stellar activity and plasma turbulence could distort narrow radio signals before they leave their home planetary systems, potentially explaining part of the long silence in the search for ...

Scientists in China have developed an AI model that analyzes stellar data from different telescopes, helping astronomers combine survey data.

A violent outburst from a nearby star has given astronomers a rare, close-up look at how stellar tempers can threaten the habitability of surrounding planets. The event, a powerful solar storm ...
