The star Betelgeuse is about 425 light-years away If it explodes tonight what would happen?
I would like to explain that in fact, Betelgeuse is closer to 640 light-years away than it is to 425 ly. So, if it goes supernova tonight, the light from this massive explosion would take 640 years to get to Earth. So, we would observe this supernova only 640 years after it has actually happened.
What else can I help you with?
When will betelgeuse die?
Betelgeuse is observed to be very unstable as of now, with large charges luminosity. It is expected to die within the next few thousand years. In fact, it might already be dead, but the light from the resulting supernova explosion could still be in transit. It takes around 640 years for that light to reach us.
What is the life cycle of a star like betelgeuse?
Betelgeuse is a red supergiant star in the late stages of its life cycle. It will eventually explode in a supernova, creating heavy elements and releasing a vast amount of energy. After the explosion, it may form a neutron star or a black hole, depending on its mass.
Is there a planet called Betelgeuse?
No one knows when it actually will become a supernova but it will take hundreds of years for the light to reach us It could be anytime. Betelgeuse is about 640 light years away. So it could have exploded anytime since 1370 (The year when the first steel crossbow was used in war) and we still wouldn't know it. Astronomers believe that the supernova from Betelgeuse will be observable by human civilization. It has recently been reported to have shrunk in diameter by 15% since 1993. It would seem that it is "pulsing", expanding and then contacting. A sure sign of a star at the end of its life. Betelgeuse is estimated at 20 solar masses and rather old, between 3.5 and 6 million years, for such a heavy weight. When Betelgeuse does explode, it will create a new major object in the winter sky. A planetary nebula will replace Betelgeuse as the shoulder star of Orion. Because of its orientation, it is unlikely to cause any major effect on Earth. Some doomsayers have said that Betelgeuse will explode in 2012 - if this is the case, we won't know until the year 2652.
Does belguese have any moons?
A star can have planets, those planets can have moons: that's the heirarchy. Actually Betelgeuse is a red giant, which means that any planets it might have had are likely to have been swallowed up as the star expanded, which is what will happen to the Earth when the Sun swells up. But it won't happen for the next few billion years.
The chemical changes that happen when a firework explodes are?
When a firework explodes, a series of chemical reactions occur, primarily involving the rapid combustion of oxidizers and fuels. The heat from the ignition initiates these reactions, producing gases, light, and heat. This results in the release of energy, which creates the vibrant colors and loud sounds associated with fireworks. Additionally, the formation of new compounds, such as metal salts, contributes to the visual effects.
When did Betelgeuse incident happen?
Betelgeuse incident happened in 1979.
What will happen when Betelgeuse explodes?
If the Sun was replaced by Orion's star Betelgeuse , its size would completely engulf the earth. Also it would extend past the orbit of Jupiter, and most of the planets would be inside the star including Jupiter. Betelgeuse would outshine the Sun like our Sun outshines the Moon. Unfortunately the Earth would have a "Front Row Seat" when the Red SuperGiant blows itself into oblivion. The explosion would be so bright that the star in Orion (constellation) which is 640 Light Years away. Days would still change from day into night, but for a few weeks or so it would appear like there are two Suns in the sky. this is what would happen when Betelgeuse explodes :)

Did betelgeuse die?
The death of a star is an event that stretches over hundreds of thousands, if not millions, of years. The exception is the explosion of a star, which can happen in as little as one day. Betelgeuse is considered to be a dying star. We know for sure that it did not explode at any time up until roughly the year 1370, because when we look at Betelgeuse in the sky tonight, we see it as it was in 1370, and the light that left it at that time is just reaching us now. It might have exploded since then, but we won't know that until we can see it. For example, if Betelgeuse exploded in 1776, then we'll see the explosion some time around the year 2415 or 2420.
