Astronomers have captured the death of a red supergiant star for the first time. The real-time discovery was published Jan. 6 in Astrophysical Journal and led by researchers at Northwestern ...

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.

Red supergiants are supergiant stars of spectral type K-M and a luminosity class of I. They are the largest stars in the universe in terms of physical size, although they are not the most massive.

Astronomers are still making new discoveries about the red supergiant star Betelgeuse, which experienced a mysterious "dimming" a few years ago.

The star is a red supergiant (like the famous Betelgeuse) and it sits in the Large Magellanic Cloud, a dwarf galaxy that contains some 30 billion stars.

The companion star, if it exists, is roughly the same mass of our Sun, and may explain Betelgeuse’s long secondary period (LSP)—a 2,170-day (6-year) cycle during which the supergiant dims and ...

The star was a red supergiant star, and while not the brightest or biggest stars out there, they are massive in volume. In fact, the scientists say the star was at least 10 times more massive than ...

Betelgeuse, the famous orange-red star shining prominently against the twinkling cohort of the Orion constellation, will soon go dark.. The supergiant star will take a notable absence from Orion's ...

The red supergiant Betelgeuse, a colossal star in the Orion constellation, experienced a massive stellar eruption -- the likes of which have never been seen before, according to astronomers ...
