Could Betelgeuse already blown up?
It's possible, yes. Betelgeuse is a red giant star that is going through the last stages of life, as viewed from earth. The light from the star takes several hundred years to reach us though, so it's possible that the star has already come to the end of it's life in that time. When it comes to the end of it's life it will explode in a supernova explosion. We should be able to see this from earth, the explosion would be so bright that we could see it during the day.
What would happen if Betelgeuse exploded?
If Betelgeuse (beetle juice) exploded then we would experience a supernova. actually Betelgeuse already had it's supernova. It's predicted that earth may see the supernova in around 2012-2013 around that year. Editing Correction: You can't detect a star going supernova before the light has reached us. This answer is biased. Claims of Betelgeuse supernova light reaching us 2012 is false. In fact it might not even go supernova the next 100'000 years. It might also be that Betelgeuse has a unsymmetrical shape and therefor is seen as shrinking. Either way, it would light up the sky as much as the full moon for a few weeks and then be visible to the naked eye fading for about a year. Also Betelgeuse is too far away from our solar system (640 Ly) to do any harm.
Would it be possible to see the star Betelgeuse even if that star had died hundreds of years ago?
When we look at stars, we are seeing the light that they are emitting. That light could have left them many years ago. The light from Betelgeuse takes over 640 years to reach us. So if it exploded today, we would not see that explosion for over 640 years. So it is possible that it is already gone, but the light that left before it went is still coming towards us.
How long does it take light to reach earth from Betelgeuse?
Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time at all in cosmic terms, but in terms of a HUMAN lifetime, it probably will NOT happen while we're alive to see it. But it could. In fact, Betelgeuse might have exploded 500 years ago, and we wouldn't know it for another 140 years!
Is betelgeuse a main sequence star?
No, Betelgeuse is not a main sequence star. It is a red supergiant star, which is a more evolved stage in the life cycle of a star compared to main sequence stars like the Sun. Betelgeuse is near the end of its life and is expected to go supernova in the relatively near future (on astronomical timescales).
Is Betelgeuse an unlucky name for a boat?
Maybe because an oil taker named Betelgeuse exploded in 1979 and many were killed, it was called the Whiddy Island disater.
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.

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.
Would it be possible to see the star Betelgeuse even if that star had died hundreds of years ago?
When we look at stars, we are seeing the light that they are emitting. That light could have left them many years ago. The light from Betelgeuse takes over 640 years to reach us. So if it exploded today, we would not see that explosion for over 640 years. So it is possible that it is already gone, but the light that left before it went is still coming towards us.

What is the life span of Betelgeuse?
Betelgeuse is only about 10 million years old - and is close to death already. It has already exhibited, an expansion and contraction of it's outer shell, which is a sure sign, that it will soon (astronomically) come to a final end as a supernova.
Have all of the stars you see in the sky all ready exploded?
No, not all stars we see in the sky have already exploded. Stars that are visible to us are typically within our own Milky Way galaxy and are at various stages of their life cycles. Some may have already exploded in supernova events, while others are still actively shining.
Is betelgeuse Latin?
No, the name Betelgeuse comes from Arabic.
