Every few years, Betelgeuse does something to grab the attention of astronomers, then the press gets excited, and everyone worries unnecessarily.\u00a0 I remember back a couple of decades reading that Betelgeuse would be the most likely cause of another mass extinction of life on earth. <\/em><\/p>\n

The only certainty is that Betelgeuse will<\/strong> blow–but the question is WHEN. Could be today, could be thousands of years from now. It might have already happened, we won’t know until some 640 years (give or take a couple of decades) after the event.\u00a0\u00a0 <\/em><\/p>\n

Orion is a winter constellation, and easy to see as it is one of the largest, and the 3 belt stars are quite obvious.\u00a0 —CPL<\/em><\/p>\n

When Betelgeuse does eventually go supernova, the brightness will rival a full moon<\/h6>\n

The dramatic dimming of a giant star has astronomers wondering whether it’s getting ready to explode.<\/p>\n

Betelgeuse \u2014 the red shoulder on the left side in the constellation Orion \u2014 has dimmed by a factor of about two<\/a><\/u>\u00a0since October, a change that has never been documented before.<\/p>\n

“We know that it’s the dimmest it’s been observed ever, based on the data we have,” said Stella Kafka, chief executive officer of the American Association of Variable Star Observers<\/a>.<\/p>\n

What makes this development particularly\u00a0intriguing to astronomers is that the\u00a0star is slated to explode in spectacular fashion: a supernova. Astronomers estimate\u00a0this will happen relatively soon \u2014\u00a0in astronomical terms anyway. It could be today, tomorrow or 100,000 years from now<\/u><\/a>.<\/p>\n

And when Betelgeuse goes supernova, astronomers estimate\u00a0it will be as bright as the full moon and visible\u00a0even during the day.<\/p>\n<\/div>\n
