As Betelgeuse burns through fuel in its core, it has swollen to massive proportions, becoming a red supergiant, the latter phase of giant stars. When the star explodes, the event could be briefly ...
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 suggest it is both smaller — and closer — than astronomers ...
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.
The 14th magnitude asteroid was predicted to occult Betelgeuse approximately 12 seconds; Betelgeuse was expected to dim by about 3 magnitudes. [17] The prediction was at first uncertain, visible on a very narrow path on Earth's surface, its width and location being uncertain due to lack of precise knowledge of the size and path of the asteroid ...
Prominent stars in the neighborhood of the Sun (center) This list of nearest bright stars is a table of stars found within 15 parsecs (48.9 light-years) of the nearest star, the Sun, that have an absolute magnitude of +8.5 or brighter, which is approximately comparable to a listing of stars more luminous than a red dwarf.
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]
Betelgeuse—the star and not the slimy, suit-wearing demon—is one of the most celebrated celestial objects in the night sky. Found in the constellation Orion, Betelgeuse is extremely bright ...
The larger northern Winter Hexagon includes seven of the twenty-two first-magnitude stars visible in the sky, with Pollux, Capella, Aldebaran, Rigel, Sirius and Procyon, and with the 2nd-magnitude Castor on the periphery, and Betelgeuse off-center. [4] Adding Betelgeuse then it is known as the Heavenly 'G'. [5]
