Will Betelgeuse explode in ‘tens of years’? – EarthSky
3 juin 2023A new paper suggests that Betelgeuse, the nearest red supergiant star to Earth, is a good candidate for the next galactic supernova. The star is in the late stage of core carbon burning and could explode soon, according to the paper. The paper also points out that the exact evolutionary stage of is not known and that the supernova timescale is uncertain.

9 juin 2023The 2,200-day (or 6-year) period isn’t generally considered part of these ins and outs, and is instead dubbed a long secondary period, a feature of unknown origin common to one-third of supergiant stars. If the 420-day period is the primary one, then Betelgeuse would have the diameter of 800 to 900 Suns lined up in a row.

Betelgeuse is a red supergiant star that will explode as a supernova sometime in the next 100,000 years. Astronomers simulated what humans will see on Earth when the star dies, and found that it will be as bright as the half-Moon for over a year. The supernova could also affect wildlife, astronomers and instruments.

Betelgeuse went dark, but didn’t go supernova. What happened?
Betelgeuse, the second brightest star in Orion, dimmed for no apparent reason in late 2019. Astronomers speculated that it was about to explode, but it returned to normal brightness by early 2020. The dimming may have been caused by a big cloud of dust blocking its light, or a change in its convection cycle.

Betelgeuse is a red supergiant star that will explode in a supernova in the future, but the exact date is unknown. The Australian researchers have calculated that it will be around 100,000 years from now, based on its size and pulsations. It is 530 light years from Earth and much smaller than previous estimates.

What is Betelgeuse? Inside the Strange, Volatile Star
3 mai 2023Betelgeuse is a red supergiant star that has a distinctive orange-red hue and is one of the brightest and largest stars in the night sky. It is nearing the end of its life and will explode in the future, but it has not done so yet. In 2019, it dimmed by 60% for several months, which puzzled astronomers and led to a new discovery of a giant cloud of dust blocking its light.
