Betelgeuse typically shows only small brightness changes near to magnitude +0.5, although at its extremes it can become as bright as magnitude 0.0 or as faint as magnitude +1.6. Betelgeuse is listed in the General Catalogue of Variable Stars with a possible period of 2,335 days. [ 8 ]
This red giant star will, one day, explode as a supernova. Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star ...
An asteroid will briefly eclipse Betelgeuse, a bright star in the Orion constellation, causing it to disappear from view for those in a narrow strip of the globe.
Humanity has marveled at the vivid star Betelgeuse for many millennia. Over two thousand years ago, this imperious red object in the constellation Orion caught the eye of the Roman poet Horace:But ...
The Orion region showing the red supergiant Betelgeuse. Red supergiants are rare stars, but they are visible at great distance and are often variable so there are a number of well-known naked-eye examples: Antares A; Betelgeuse; Epsilon Pegasi; Zeta Cephei; Lambda Velorum; Eta Persei; 31 and 32 Cygni; Psi 1 Aurigae; 119 Tauri
Antares, like the similarly sized red supergiant Betelgeuse in the constellation Orion, will almost certainly explode as a supernova, [61] probably in 1.0 to 1.4 million years. [10] For a few months, the Antares supernova could be as bright as the full moon and be visible in daytime. [53]
Betelgeuse has entered an uncommon period of brightening again, this time rising in brightness by around 50 percent. Is the star about to go supernova?
Astronomers pointed powerful telescopes at the red giant star Betelgeuse, confirming theories that the star had not almost exploded a few years ago, but it did experience a dimming event.
