Red supergiants (RSGs) are stars with a supergiant luminosity class (Yerkes class I) of spectral type K or M. They are the largest stars in the universe in terms of volume, although they are not the ...

An investigation using the star-surveying Gaia space telescope revealed that the Barbá 2 is packed with red supergiant stars, stars that can be hundreds of times wider than the sun and up to ...

This is an artistic impression of a red supergiant star surrounded by a veil of circumstellar material before explosion as suggested by early time observations of type II supernova. Disclaimer ...

In late 2019 the red supergiant closest to Earth, Betelgeuse, began to rapidly fade in brightness. Initially thought to be a sign that the star was about to go supernova or that it experienced a dust ...

One of the largest known stars, UY Scuti is a red supergiant with a radius 1,700 times that of the Sun, located 9,500 light-years away. Known as “Herschel’s Garnet Star” due to its red hue, Mu Cephei ...

Betelgeuse’s future supernova won’t harm Earth, but close cosmic explosions could strip our ozone, risking life. Gamma-ray ...

"And yet there's still room to make significant new discoveries: in this case, a sunlike star hiding in plain sight, in the immense glare of a red supergiant. That is what excites me the most." ...
