Any of various very massive, large, and bright stars, such as Betelgeuse or Rigel, having a luminosity that is thousands of times greater than that of the sun. When a supergiant collapses into a supernova, it may result in either a neutron star or a black hole. ...
that they stand out in external galaxies. There is an upper limit to the absolute bolometric magnitude of cool red supergiants (–9.7), so the brightest supergiants can be used as approximate distance indicators. Examples of supergiant stars are Rigel and Betelgeuse in Orion, Antares in Scorpiu...

Betelgeuse—one of the most prominent stars in the Milky Way, a part of the Orion constellation—still seemingly acts like a normal star, and may even be recovering. After analyzing the 2019 data, astronomers have concluded that this is behavior we’ve never seen before in a normal star. ...
The star named Betelgeuse is an example of a red supergiant, located on the right shoulder of the constellation Orion. VY Canis Majoris is another example and is one of the largest known stars.What is a Red Supergiant? There are several types of stars that appear in the night sky. They ...
Supergiants are rare and short-lived stars, but their high luminosity means that there are many naked-eye examples, including some of the brightest stars in the sky. Rigel, the brightest star in the constellation Orion is a typical blue-white supergiant; Deneb is the brightest star in Cygnus...
“We still have much to learn about supernovae and related objects and phenomena, but I think this research will help astronomers fill in some of the blanks,” said Taniguchi. “The giant star Betelgeuse (on Orion’s shoulder) could go supernova in our lifetimes; in 2019 and 2020 it...
