Many red supergiant monster stars lurk in a Milky Way cluster astronomers have discovered with the Gaia space telescope. The cluster, Barbá 2, could help understand why some stars become black holes.

Because the red supergiants in this cluster are still relatively bright, Figer’s team estimates that the star cluster is relatively young, between 8 and 10 million years old.

A massive cluster of red supergiants--super-sized stars on the verge of exploding--was recently discovered in the Milky Way by a group of stronomers using infrared technology to penetrate the ...

Betelgeuse is having a moment. The famous red supergiant star in the constellation of Orion has been visibly dimming in recent weeks, leading some to ponder whether it might be about to go ...

Like many similar red supergiants, KQ fluctuates slightly in brightness, causing the overall magnitude to change between 4.82 and 5.17. Open cluster M46 lies just over a degree east of M47, so it ...

The scientists looked at stars in the Perseus stellar cluster — a region with a high concentration of stars, particularly red supergiants, located around 7,500 light-years from the solar system ...

Venus continues to be the “Morning Star” in the east before dawn, albeit it has become dimmer — but still bright — as it ...

Red-supergiant supernova images reveal secrets of an earlier universe An international research team led by the University of Minnesota Twin Cities has measured the size of a star dating back 2 ...

About 11.5 billion years ago, a distant star roughly 530 times larger than our sun died in a cataclysmic explosion that blew its outer layers of gas into the surrounding cosmos, a supernova ...

Astronomers just found a time-lapse view of star exploding 11.5 billion years ago. Using a massive galaxy cluster as a magnifying lens, the Hubble Space Telescope captured the images of the ...
