Betelgeuse, one of the most luminous stars visible from Earth, continues to surprise astronomers. The red giant’s brightness fluctuations have long intrigued scientists, but new research ...

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

As 319 Leona passes in front of Betelgeuse and blocks its light, a very slight star shadow will fall across Earth’s surface. However, while the occultation of a star by an asteroid is typically ...

The gaps in these measurements happen when Betelgeuse appears in Earth's day sky, making it impossible to take precise brightness measurements. During this observation gap in 2020, NASA's STEREO ...

Despite Betelgeuse’s impending explosion, Earth is safe. At around 650 light-years away, the star is too distant for its radiation or shockwaves to reach Earth with dangerous intensity.

Average stars like our sun die ignominiously. They swell to enormous size, cool from yellow to red hot, and shed most of ...

An asteroid the width of Manhattan will be close enough to Earth tonight to be seen with ... of the belt to the left shoulder — the famous Betelgeuse — and follow that in a straight line ...
