It depends how far it is.Super nova's are VERY big.you would probably not see it but they are big.There were no close super nova's near earth.They were all at the other side of the galaxy or somewhere in another galaxy.

How far is the closest star to earth?
The closest supernova, or more correctly supernova remnant, is the Vela supernova remnant [See Link] in the constellation Vela. The "guest" star exploded about 11 - 12,000 years ago and is located around 800 light years from Earth.
A supernova explosion was observed on earth in 1987 but the explosion actually took place about 16900 years ago how is this possible?
The speed of light is about 300,000 kilometers per second (186,000 miles per second). So by the time you even got past typing the first letter of this question, you, the Earth and everything else you know would be obliterated. It would have taken approximately one-sixth of a second for the light from the supernova to reach Earth.
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.
Who named the supernova star?
A supernova is not a single star, but an event that occurs to the most massive stars when they reach the end of their life. Therefore it cannot be named. See related questions for details on Supernova
What happens to the moon during the daytime?
nothing. earth turns around, when its night in your country you see moon when its morning earth turns and you see sun
How long would it take for us to see a supernova on earth?
That depends entirely on how far the supernova is from Earth. If it is our Sun going supernova, a little over 8 minutes. And a few Milli-seconds later all life on Earth would be gone. Any other star, it would just appear slightly brighter for a while and then disappear. It could take centuries for the light to reach us.
Are supernova dangerous to the earth?
A near Earth supernova [See Link] is a supernova that occurs close enough to the Earth (less than 100 light-years away) to have noticeable effects on its biosphere. Gamma rays from a supernova induce a chemical reaction in the upper atmosphere, converting molecular nitrogen into nitrogen oxides, depleting the ozone layer enough to expose the surface to harmful solar and cosmic radiation. This has been proposed as the cause of the Ordovician extinction - [See link], which resulted in the death of nearly 60% of the oceanic life on Earth. Type Ia supernova [See Link] are thought to be potentially the most dangerous if they occur close enough to the Earth. Because these supernova occur from dim, common white dwarf stars, it is likely that a supernova that could affect the Earth will occur unpredictably and take place in a star system that is not well studied. The closest known candidate is IK Pegasi [See Link] Recent estimates predict that a Type II supernova would have to be closer than 26 light-years to destroy half of the Earth's ozone layer.
Can you see a supernova from earth without a telescope?
In some cases, yes. It depends on the magnitude of the supernova and how close it is. Some are even bright enough to be seen during daylight.
If a white dwarf steals another stars hydrogen what happens?
It becomes a Type Ia supernova [See Link]
What is a supernova and how many are there?

Would Earth be affected when VY Canis Majoris explodes as a supernova?
Given the fact we are 5000 light years away from VY Canis Majoris, I doubt it would do much damage to Earth. However, Earth could be hit by a large gamma ray burst, but that is unlikely. Also, when the star does explode we will be able to see it from Earth, and it will outshine the galaxy for weeks and months.
How long would it take to see a star explode on earth?
That depends on how far away the star is. If the exploding star is 1,000 light years away we would see the supernova 1,000 years later. If it is 2,000 light years away we would see it 2,000 years later.
If mars were to explode would you be able to see it from earth?
Yes. You would. Mars can be seen from Earth because it's so close to us. But if the whole planet were to blow up or explode, we would be able to see it. Whatever what the explosion would look like if it happens to Mars, then surly we could see it.
If a star near us went nova would we be able to see it on earth?
Yes. If it were big enough and near enough, we might even be able to see it in the daytime, like the 1006 supernova. We expect the star Betelgeuse, the red giant star at the shoulder of Orion, to go supernova "sometime soon". However, "soon" to an astronomer means within the next few thousand years, so don't go expecting it this week. If\\\WHEN Betelgeuse goes supernova, it will be brighter than the Moon.
When has a supernova ever hit the earth?
If a supernova - or any star, for that matter - would have hit Earth, the Earth would have been utterly destroyed. Earth still exists, ergo this didn't happen._____________________However, it is likely that a supernova - more precisely, SEVERAL supernovas - CREATED the Earth.The Earth is made of heavy elements; iron, lead, uranium, gold, and heavy metals in addition to the lighter stuff like carbon, oxygen, silicon, and magnesium. The point is that the original Big Bang was composed of mostly hydrogen, a little helium, and traces of lithium; the LIGHTEST elements. So where did the metals come from? Supernova explosions are the only way that heavy elements can be created and thrown back into space.So the dust and gas left over from a few supernovas gathered together as a nebula. But what would cause a nebula to collapse and form a star and a solar system? Our theories indicate that the shockwave of a "nearby" supernova might easily have been the final impetus to cause a nebula to coalesce and form a solar system.Other supernova explosions may have been responsible for some of the mass extinctions that we see in our historical record. Several times in the past, we know that most living things on Earth all died quite suddenly. Some of these - for example, the dinosaurs - were probably caused by asteroid impacts into the Earth. But some may have been caused by the radiation from a supernova explosion.
What would a supernova look from earth?
Nobody really knows. However we do know that is a spherical object - not an oblate spheroid - about the size of Manhattan (about 12km in diameter) with a very smooth surface. Smoother than anything on Earth. A young one will be very hot, and it will have a massive gravitation density. See related questions.
