Betelgeuse has hit the headlines in recent weeks as astronomers noticed that it was gradually dimming. Stars supernova when they are at the end of their lives and have run out of fuel after many millions of years.
Now, researchers have noticed a strong burst of energy coming from near to the star, which one astronomer had hoped was a result of Betelgeuse undergoing a supernova. The opulence is short-lived as the fireball fades away”, NASA said in a statement. After Itagaki informed NASA, the space agency started observing it using the Hubble telescope, located in space. Mr Howell added: “It isn’t Betelgeuse blowing up because: The burst might not even be real. If the star continues to follow above periods, light minimum should occur soon.”. Yahoo fait partie de Verizon Media. This yardstick is needed to calculate how quickly galaxies appear to be flying apart from one another, which in turn provides an age estimate for the universe”, NASA said in a statement. 01:02. The supernova SN 2018gv was first discovered by an amateur astronomer, Koichi Itagaki from Japan in 2018. For reference, smaller stars like the sun will live for around 10 billion years.
However, as it turned out, the gravitational wave data was more likely a glitch in the system.

Gravitational waves are caused by calamitous events in the cosmos such as neutron stars colliding or black holes merging, which produce such a powerful shock that it sends ripples through the fabric of space-time.
CTRL + SPACE for auto-complete. I was mostly joking (but I did walk outside because I couldn’t resist).”. No neutrinos were detected.

newspaper archive. Betelgeuse’s dimming is well explained.”. “The type of supernova seen in this sequence originated from a burned-out star — a white dwarf located in a close binary system — that is accreting material from its companion star. When the white dwarf reaches a critical mass, its core becomes hot enough to ignite nuclear fusion, turning it into a giant atomic bomb.
