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 ...
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 ...
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 ...
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]
The secondary companion is a yellow main-sequence star of spectral type G5V that is a little smaller (0.9 times) the diameter of the Sun. [15] Lying 75±0.5 light-years from Earth, [16] Alphecca is believed to be a member of the Ursa Major Moving Group of stars that have a common motion through space.
The Hubble Space Telescope revealed why nearby red giant star Betelgeuse became surprisingly dim late last year, according to a new study. It was likely not a precursor to a supernova explosion.
