Betelgeuse showing signs of supernova explosion explodes to full moon-level brightness
by
The brightness of the first star Betelgeuse in Orion is so low as to be unprecedented in the history of observations, and is pointed out as a sign of a supernova .

To astronomical observation team of Villanova University in the United States, Pennsylvania, in December 2019, 'Since October 2019, the star of Orion Betelgeuse and brightness of has become a half, was recorded observation all-time low' announcement Did.
'The darkening of Betelgeuse indicates that a supernova is about to occur. I don't know exactly, but if the explosion occurred,' said Malcolm Davis, senior analyst at the Australian Institute for Strategic Policy . It will shine as bright as a full moon, 'he wrote on Twitter.
#Betelgeuse is dimming, which is an indication that it will go supernova soon-when we don't exactly know.When it happens (it would have actually happened ~ 690 years before we see it on Earth given the star's distance) it will be as bright as the full moon.https: //t.co/dPYMROKn9A

Amateur astronomer and planetarium operator Dave Eagle commented on how Betelgeuse exploded, `` When Betelgeuse is brightest, it looks like a full moon, but unlike the moon, Betelgeuse is small. because the point, and you will be Orion looks pretty strange, ' said we.
He added that the effect of supernovae on the Earth is not that the gamma-ray bursts generated by the supernovae ionized the Earth's atmosphere and caused a large-scale forest fire to trigger human bipedalism. of whether ' research results from the fact that there is also such as supernova of Betelgeuse is in the past a significant impact on the human race had been also feared the possibility.
However, many experts point out that Betelgeuse's supernova is unlikely to have any significant effect on Earth. In Reddit of online bulletin board Andromeda321 Yvette Cendes Mr. astronomers who are active as is, as 'Betelgeuse supernova is or after 100,000 years if longer, it seems that it is after at least a few million years' post .
'Speaking frankly, it's hard to predict when Betelgeuse's life will expire. We don't know if it will be tomorrow, 50,000 or 100,000 years, but it will happen in our lifetime. The probability of doing so is very small. ' Also, physicist Adrian Mellot, who discussed the evolution of mankind caused by the aforementioned supernova, said, `` Betelgeuse, which is about 200 parsecs (about 600 light years) from the earth, will not cause serious consequences. '' He pointed out that even if Betelgeuse exploded immediately, it was too far away and had little effect.
Nevertheless, the Betelgeuse supernova, which is 200 parsecs, which is fairly close in space, is definitely a valuable astronomical phenomenon. 'Whatever happens, it's worth seeing. It's a once-in-a-lifetime time for a supernova to occur in our galaxy,' said David Boyce, director of physics at Uppingham School in the UK. It will be a good memory for the children. '
Whatever happens it will be worth watching.A supernova within our galaxy is a once in a lifetime spectacle.One as close as #betelgeuse would be one to wake the kiddies up for.
