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. ... it is rare for space rocks to ...
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?
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—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 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 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 ...
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]
