Answer: Betelgeuse is 650 light years from Earth so it takes light 650 years to reach us . If the explosion happened in the Year 3000 AD, then we will see the light arrive in the year 3650 AD, 650 years AFTER the event occurred.
Betelgeuse is around 700 light-years away. This means that it takes the light from this star about 700 years to reach Earth, so if you see Betelgeuse in the night sky, you're seeing the star from about 700 years ago.
Assuming that our fastest spacecraft can travel at about one light-year per 20,000 years, it would take us 12,800,000 years to reach Betelgeuse. This distance should provide some relief to those worrying about Betelgeuse going supernova in the future.
Either way, it seems likely that Betelgeuse will be the Milky Way galaxy's next supernova but this wouldn't happen anytime soon. It could even be another 100,000 years before Betelgeuse's light is finally extinguished.
Now consider this: It's believed that Betelgeuse, a giant red star in the constellation Orion, is approaching the end of its life cycle. Most scientists believe it will become a supernova in the near future.
LIVE Betelgeuse Supernova Explosion Is Finally HAPPENING NOW!
Is Betelgeuse exploding right now 2023?
Although some hype up Betelgeuse's looming doom, its coming explosion, called a supernova, might not happen for at least tens of thousands of years, if not more like some 100,000.
While Betelgeuse's supernova is not expected to cause direct harm to life on Earth, it could potentially have some atmospheric effects. The explosion would release a burst of ultraviolet radiation, which could deplete the ozone layer temporarily.
Whenever Betelgeuse does blow up, our planet Earth is too far away for this explosion to harm, much less destroy, life on Earth. Studies indicate we'd have to be within 160 light-years of a supernova for it to harm us. And Betelgeuse is perhaps four times this distance.
“We conclude that Betelgeuse should currently be in a late phase (or near the end) of the core carbon burning,” the paper notes. “After carbon is exhausted in the core, a core-collapse leading to a supernova explosion is expected in in a few tens [of] years.”
Gaia BH1 is located 1,560 light-years away from Earth, while Gaia BH2 lies around 3,800 light-years away. Even though this means both black holes are located in Earth's backyard (in cosmic terms, at least),they are still over 10 and 20 times as far away as the Hyades cluster and its potential black hole duo or trio.
While it is challenging to accurately determine the exact year when Betelgeuse will go supernova, astronomers have made predictions based on observations and scientific models. As of the latest research, it is believed that the supernova event could occur within the next 100,000 years.
The closest star to us is actually our very own Sun at 93,000,000 miles (150,000,000 km). The next closest star is Proxima Centauri. It lies at a distance of about 4.3 light-years or about 25,300,000,000,000 miles (about 39,900,000,000,000 kilometers).
The largest known star in the universe is UY Scuti. It has an estimated radius of 1.188 billion kilometers. If UY Scuti were the center of our solar system, its photosphere, or outer shell, would reach just past the orbit of Jupiter.
Betelgeuse is an enormous star. If we were to place it at the center of our solar system, it would extend all the way to Jupiter. The star's size, combined with its position in our galaxy, the Milky Way, allows astronomers to study Betelgeuse in better detail than most stars.
Dr Stanimir Metchev also said that it was unlikely that it would happen in our lifetime. He said the last stages of a star's life can last hundreds of thousands of years.
Betelgeuse does not have any planets orbiting it, as far as we know. Additionally, the position of Betelgeuse is RA 05 h 55 m 10.3053 s, dec+07° 24'25.4” [1-4]. FIG.
Factors such as stellar mass, nuclear fuel consumption, and shock wave propagation influence the duration of such events. While estimates suggest that Betelgeuse's supernova could last anywhere from weeks to months, the precise timing remains elusive.
This fiery demise is what astronomers call a supernova explosion, and in the case of Betelgeuse, it will be a spectacular sight for observers on Earth. Since the star is only 650 light-years from Earth, those layers of gas and dust will shine as bright as the full moon in our sky for several weeks.
Betelgeuse is a so-called red supergiant, 887 times as large as our own sun. Its surface, like the sun's, resembles boiling oatmeal as blobs of gas rise, conveying heat and energy.
Jupiter's perigee – or closest point to the Earth for 2023 – comes at 21 UTC (4 p.m. CDT) on November 1-2. That's when the distance between the Earth and Jupiter will be at its least for 2023.
The presence of iron-60 suggests that Earth was hit by supernova ejecta as recently as a few million years ago. Based on the threats posed by gamma-rays and cosmic rays, astronomers have already concluded that we are relatively safe; there are no nearby supernova candidates that can pose a threat to life on Earth.
Our sun isn't massive enough to trigger a stellar explosion, called a supernova, when it dies, and it will never become a black hole either. In order to create a supernova, a star needs about 10 times the mass of our sun.
