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 ...
One of the biggest and brightest stars in the night sky has left astronomers puzzled after it has faded dramatically over the last year. Some have speculated that this is a sign of an impending ...
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? Betelgeuse Is Being Weird Again
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]
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae.
The constellation Corona Borealis as it can be seen by the naked eye. Alpha Coronae Borealis (officially named Alphecca by the IAU, but sometimes also known as Gemma) appears as a blue-white star of magnitude 2.2. [12] In fact, it is an Algol-type eclipsing binary that varies by 0.1 magnitude with a period of 17.4 days. [13]
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.
