Star Antares and its vicinity, at Scorpius Constellation. Dr Brown says there's definitely no reason to be concerned about what Betelgeuse will do for now. "It's sufficiently bright that you can see it even if you're in the city and you've got city lights around you, you can see it in the suburbs, you can see it in the country. The following video animates the current motions of stars in Orion, projecting them 450,000 years in the future. Notice Betelgeuse and Rigel on either side of the short, straight row of three medium-bright stars. "As it has done plenty of times in the past, Betelgeuse will eventually gain brightness again and all will be back to usual," he explains. Many astronomers are confident that Betelgeuse will go supernova at some point, but it's more likely to happen tens of thousands of years from now. Bételgeuse (forme internationale : Betelgeuse) est le nom propre de l'étoile qui a été approuvé par l'Union astronomique internationale le 20 juillet 2016 [7]. Scientists have been discussing a number of scenarios trying to explain its behaviour. "It is unusual in our lifetimes for Betelgeuse to be this faint, but in the overall lifetime of red giant stars, which is thousands and thousands of years, it's not necessarily that unusual.". Pronounced "beetlejuice", the star is roughly 10 times bigger than our Sun in mass. "The dimming of the brightness is the typical behaviour of the star. "It's unusual for us to see Betelgeuse this faint, but red giant stars are quite variable and Betelgeuse doing this isn't necessarily out of the ordinary over the scale of many thousands of years," he says. One of the world's most recognisable stars is starting to look very different — and it's got the astronomy world talking. The star, named Betelgeuse, has dimmed its brightness so significantly that you can see the difference with the naked eye. Betelgeuse is an excellent example of this — in just 100,000 years, it will leave its home in the Orion constellation. As the winter months progress, January and February, at the same time it will be higher in the sky allowing an optimal observation. In terms of our lifetimes, unfortunately, we're probably going to miss out on seeing Betelgeuse go supernova, which is sort of a pity because it would be quite a show.". Betelgeuse is a red giant star in the constellation Orion, one of the most familiar constellations in the night sky.

"We see Betelgeuse now as it was about 700 years ago, so it's possible that Betelgeuse went supernova 500 years ago, and we wouldn't know about it for another two centuries," Dr Brown says. "One of the beautiful things about Orion and Betelgeuse is it's one of the brightest, most recognisable constellations in the sky," he says.

It's pretty easy to find if you haven't looked at it before. Even if Betelgeuse did go supernova, we won't see the light show instantly. There's been speculation that this dimming means Betelgeuse will turn into a supernova, which has some astronomy fans excited. We could keep our focus on the fires, say, rather than worrying about Betelgeuse going supernova on us. Macquarie University Astrophysicist and science communicator Angel Lopez-Sanchez says if Betelgeuse does explode, it will be visible during the day and could take months to fade.
