The James Webb Space Telescope (JWST) has once again unveiled groundbreaking insights into the universe, this time highlighting the incredible starburst activity in Messier 82 (M82), also known as the ...

Astronomers have created the most detailed image of a galaxy of its kind ever seen. The “incredibly detailed” picture shows ...

"Civilizations like this that consume stars, which we call 'stellivores,' would be able to expand in energy use beyond the ...

“ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain ...

Stars spend 90 percent of their lives in their main sequence phase. Now around 4.6 billion years old, Earth’s sun is considered an average-size yellow dwarf star, and astronomers predict it will ...

Paired with the star’s surging luminosity, this means that gas will start to flow away from it, creating a “stellar wind” that can eventually eject more than half the star’s total mass.

“ASKAP J1832–0911 is currently the only LPT detected with (pulsed) X-ray emission — perhaps unsurprisingly, given its extreme radio brightness and the potential correlation between the radio and X-ray ...
