If Betelgeuse Explodes, Just How Bright Will It Get?

Wired  

Theres a famous star that I'm sure you've seen in the sky. This red supergiant has dimmed repeatedly in the past few years, which could mean that it's ready to go full supernova quite soon—and by “soon” we mean within the next 10,000 years. However, this is countered by the outward-pushing force from the core, so the star remains fairly …

Betelgeuse, star doomed to explode anytime, eclipsed by asteroid in deep space

India Today  

Astronomy enthusiasts across Europe had their telescopes trained on the night sky in anticipation of a significant celestial event—the occultation of Betelgeuse by asteroid Leona. Betelgeuse was supposed to dim at least 3 magnitudes when asteroid Leona passed in front of it. Betelgeuse, a red supergiant star located in the constellation Orion, was expected to dim significantly — by at …

Associated Press  

CAPE CANAVERAL, Fla. — One of the biggest and brightest stars in the night sky will momentarily vanish as an asteroid passes in front of it to produce a one-of-a-kind eclipse. The rare and fleeting spectacle, late Monday into early Tuesday, should be visible to millions of people along a narrow path stretching from central Asia’s Tajikistan and Armenia, across …

Betelgeuse is a red supergiant star, the western shoulder of the hunter Orion. So if Betelgeuse went supernova yesterday, we would only know 642 years from today. Basically, our best shot is that Betelgeuse went supernova 642 years ago today. Aliens “might” use a recent supernova in the Pinwheel Galaxy to communicate with earth. The aliens sent us a message …

Explained | Will Betelgeuse, the red giant star, blow up in your lifetime?

The Hindu  

The bright red star Betelgeuse, called ‘Thiruvathirai’ or ‘Ardra’ in Indian astronomy, is easily spotted in the constellation Orion. In massive stars like Betelgeuse, the carbon-burning stage lasts only up to a few hundreds of years, after which the star ‘dies’ and collapses into a supernova within a few months. Likewise, the researchers say Betelgeuse’s observed pulsation matches theoretical estimates …

Astronomers have determined after studying data from Nasa's Hubble Space Telescope and a number of other observatories that the bright red supergiant star Betelgeuse essentially blew its top in 2019, losing a significant portion of its visible surface and creating a massive ‘surface mass ejection’. “If placed at the centre of our solar system it would reach out to the …

Every journey has a beginning and an end, and so is the case for cosmic objects, one among them is a red supergiant star — Betelgeuse. Betelgeuse is the nearest red supergiant star to Earth and it garnered global attention when it suddenly began dimming in 2019. Astronomers have now confirmed with evidence that the bright red supergiant star did …

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, which included five other members — Shing-Chi Leung, László Molnár, Michael Ireland, …

Firstpost  

The unprecedented drop in its brightness observed last year led to speculations that the star may be about to explode. Researchers from Ken’ichi Nomoto at the Kavli Institute for the Physics and Mathematics of the Universe conducted a rigorous examination of the star and concluded that the star is in the early core helium-burning phase and has smaller mass and …

'Traumatic Outburst': NASA's Hubble Telescope Finds Why Betelgeuse Star is Dimming

News 18  

he mysterious dimming of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into space, forming a dust cloud that blocked starlight coming from the star's surface, show observations by NASA's Hubble Space Telescope. The dust cloud formed when superhot plasma unleashed from an upwelling of a large convection cell on the star's …

CNN — Betelgeuse, the red supergiant star that acts as the shoulder of Orion in his constellation, intrigued astronomers when the normally bright star showed signs of unprecedented dimming in December. New research has suggested that large star spots, like sunspots on our sun, are on the surface of Betelgeuse and causing the dimming. And the most probable cause of …
