To give a sense of scale, if Betelgeuse were placed at the center of our solar system, its surface would extend beyond the ...

Betelgeuse, approximately 100,000 times as luminous as the Sun and 400 million times its volume, is nearing the end of its life. As a variable star, it pulses with a heartbeat-like rhythm.

Nobel Prizes honored research in biology and AI, including foundational work on artificial neural networks, which enable machine learning and other ...

Co-author Meridith Joyce and her team have proposed an out-of-this-world theory: Betelgeuse may have a partner, affectionately dubbed "Betelbuddy." This sun-sized companion star could be ...

New images created by the Hubble Space Telescope show that Betelgeuse — one of the brightest stars visible from Earth — wasn’t dimming because it was about to explode, but because there was ...
