Astronomers report the rapid transition of WOH G64 from a red supergiant to a yellow hypergiant, based on photometric and spectroscopic observations published in Nature Astronomy.

Star maps and charts are a mainstay of both amateur and professional sky observers. Whether it's on a simple seasonal map or in a comprehensive atlas, the stars listed appear steadfast and constant.

A distant star dimmed by 97% for nearly 200 days. Astronomers say giant rings around a brown dwarf or super-Jupiter may explain it.

One of the largest stars close enough for us to estimate its size, WOH G64, appears to have gone from red to yellow in 2013-14, indicating a temperature rise of about 1,000°C (1,800°F). Last year it ...

Astrophysicists have achieved an eye-opening leap in understanding stellar death, capturing unprecedented, detailed images of two exploding stars that demonstrate these blasts are far more complicated ...
