Just like the mischievous Tim Burton character of the same name, the red supergiant star Betelgeuse's head shrank. Scientists watched the star blast its outer surface into space in 2019, an ...
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. ... be visible to millions who ...
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 ...
Consequently, it is likely that Betelgeuse has not always had its current motion through space but has changed course at one time or another, possibly the result of a nearby stellar explosion. [ 107 ] [ 157 ] An observation by the Herschel Space Observatory in January 2013 revealed that the star's winds are crashing against the surrounding ...
Antares, like the similarly sized red supergiant Betelgeuse in the constellation Orion, will almost certainly explode as a supernova, [61] probably in 1.0 to 1.4 million years. [10] For a few months, the Antares supernova could be as bright as the full moon and be visible in daytime. [53]

These parameters are all consistent with those estimated for Betelgeuse. [11] The initial mass of Mu Cephei has been estimated from its position relative to theoretical stellar evolutionary tracks to be between 15 M ☉ and 25 M ☉. [11] [15] The star currently has a mass loss rate of (4.9 ± 1.0) × 10 −7 M ☉ per year. [11]
However, even at 530 light-years distance, our planet will still be safe from the eventual explosion. Skywatchers observing Betelgeuse should also keep an eye (or two!) out for the Orionid meteor ...
