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.
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.
What kind of storms do black holes and supernovas cause in Earth's upper atmosphere?
None for now. However, should a supernova explosion occur in our "neighborhood" (anywhere within a few thousand light-years in this case!), the strong radiation might have a severe impact on life on Earth.None for now.

Can the earth go supernova?
No. There are two ways of generating a supernova: a star at least 8 times the mass of the sun collapsing and exploding or a white dwarf interacting or colliding with a companion star. Our sun is not massive enough to explode when it dies and does not have a companion star.
When will canis majoris go supernova?
It is difficult to predict exactly when Canis Majoris, or Betelgeuse, will go supernova. It is expected to happen within the next 100,000 years, but could occur sooner or later. When it does happen, it is likely to be a spectacular event visible from Earth.
How many light years away does a Supernova have to be to destroy Earth?
For a supernova to directly destroy Earth, it would need to be less than 10 light years away. However, even if a supernova were to occur farther away, its effects on Earth's atmosphere and climate could still be substantial.
Can a supernove occur on earth?
No, the earth is much too small to be able to be capable of a supernova event. These are only possible in stars much larger than the Sun.

Does earth have storms?
Yes. Our planet has snowstorms, hurricanes, thunderstorms, excessive rain, etc.. Although this doesnt occur often.
What makes a supernova occur in a star's lifecycle?
A supernova occurs in a star's lifecycle when it runs out of fuel and its core collapses, causing a massive explosion.

When will 24 hours of light exist on Earth because of a star going supernova?
When the second largest known star, in the universe, goes supernova, this will occur. (Estimates range from this happening in the year 2012, all the way to one million years from now.) The name of this giant star is Betelgeuse.

What is the Vela Supernova?
The Vela Supernova is the remnant of a supernova explosion that occurred in the Vela constellation about 11,000 to 12,300 years ago. It is located about 800 light-years away from Earth and is one of the closest known supernova remnants to us.
Is a supernova bigger than earth?
Much bigger. Earth is a relatively small planet, much smaller than even a dwarf star. A supernova is a very large star exploding.
