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 ...
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 ...
Betelgeuse is a red supergiant star about 700 light-years away that serves as the shoulder in the Orion constellation, according to NASA. Given its intense luminosity, Betelgeuse is what ...
A supernova (pl.: supernovae or supernovas) is a powerful and luminous explosion of a star. ... [240] the red supergiants Betelgeuse, Antares, and VV Cephei A; ...
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 ...
A supernova can briefly emit as much energy as an entire galaxy, brightening by more than 20 magnitudes (over one hundred million times brighter). The supernova explosion is caused by a white dwarf or a star core reaching a certain mass/density limit, the Chandrasekhar limit, causing the object to collapse in a fraction of a second. This ...
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.
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 ...
