If Betelgeuse were too close to Earth, the eventual supernova could cause an extinction here on Earth. However, even at 530 light-years distance, our planet will still be safe from the eventual ...
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 ...
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 ...
As seen from Earth, Betelgeuse as a type II-P supernova would have a peak apparent magnitude somewhere in the range −8 to −12. [183] This would be easily visible in daylight, with a possible brightness up to a significant fraction of the full moon, though likely not exceeding it. This type of supernova would remain at roughly constant ...
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
Intermediate "super-AGB" stars, around 7-9 M ☉, can undergo carbon fusion and may produce an electron capture supernova through the collapse of an oxygen-neon core. [ 24 ] Main-sequence stars, burning hydrogen in their cores, with masses between 10 and 30 or 40 M ☉ will have temperatures between about 25,000K and 32,000K and spectral types ...
Damian Lillard is the only one going supernova these days. The Hubble Space Telescope revealed why nearby red giant star Betelgeuse became surprisingly dim late last year, according to a new study.
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [93] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [99] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [100]
