Giant Red Star Betelgeuse Will Take Another 1,00,000 Years to Explode, Says Study FOLLOW US ON: A recent study has found that even though it may seem that the giant red star Betelgeuse is ready to die any moment, it will take another 1,00,000 years for it to actually perish. A team of international scientists led by Meridith Joyce from the Australian National University (ANU), which included five other members Shing-Chi Leung, László Molnár, Michael Ireland, Chiaki Kobayashi, and Ken ichi Nomoto published their findings in The supergiant star is a part of the Orion constellation and has piqued scientists interest due to its conspicuous behaviour lately. In a statement to the Australian National University, Dr Joyce said that normally Betelgeuse is one of the brightest stars in the sky, but her team observed two drops in the brightness of the star since late 2019. This development prompted the speculation that it could explode soon but the study offers a di ....
Study of Supergiant Star Betelgeuse Unveils the Cause of its Pulsations; Recalibrated its Mass, Radius, and Distance Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020 (Figure 1), which has prompted speculation that Betelgeuse may be about to explode. Fig 1: Recent brightness variations of Betelgeuse. Stellar pulsation causes the star’s brightness to vary, but the large dip in brightness in early 2020 is unprecedented. A comparison of direct images of the surface of Betelgeuse between January 2019 and December 2019 show that large portions of the star faded in December 2019, which could indicate a dust cloud appearing in front of it. The images were taken by the European Southern Observatory’s (ESO’s) Very Large Telescope. For brightness data, see the cap ....

Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020 (Figure 1), which has prompted speculation that Betelgeuse may be about to explode. To find out more, an international team of scientists, including Ken ichi Nomoto at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), conducted a rigorous examination of Betelgeuse. They concluded that the star is in the early core helium-burning phase (which is more than 100,000 years before an explosion happens) and has smaller mas ....
