Supernovas are massive stars that have exploded. It is not a name for a single star.Therefore their distances are varied.
The Crab nebula (A former supernova) is located at a distance of about 6,500 light years.
SN1987A (Seen in 1987) is about 168,000 light years from us. So the supernova occurred around the time of the emergence of homo sapiens.
SN2006gy (Seen in 2006) is about 238 million light years from us. So it exploded around the time Vertebrates ruled the world!!
Vela exploded approximately 11,000-12,300 years ago (and was about 800 light years away).
What else can I help you with?
Who was the Danish astronomer who proved that a supernova was far away?
Tych Brahe
How far is the crab nebula?
The crab nebula is estimated to be about 6,300 light year away.
How far is supernova from the sun?
Supernovae can occur at varying distances from the Sun, ranging from hundreds to thousands of light-years away. When a supernova occurs within our Milky Way galaxy, it can typically be tens to hundreds of light-years away. However, there are some exceptionally bright supernovae that can be observed even at greater distances.
What would happen if all the suns that can go supernova went supernova at the same time?
There are huge spaces between stars. The biggest threat to Earth would be the gamma radiation emitted, which could sterilize the Earth from as far as 10 light-years away.
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.
How far from a supernova do you have to be to be safe?
About 50 to 100 light-years as the closest safe distance between Earth and a supernova. But, if a supernova to go off within about 30 light-years of us, that would lead to major effects on the Earth, possibly mass extinctions.
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.
What was the first supernova called?
Probably the Vela supernova in the southern constellation Vela. Its source supernova exploded approximately 11,000-12,300 years ago (and was about 800 light years away).
Is Betelgeuse going to destroy earth?
No. Some time in the next million years Betelgeuse will explode as a supernova, but it is too far away from us to damage the earth. All we will see is Betelgeuse getting a lot brighter in the night sky.
When was the last super nova seen in the milkey way galaxy and who saw it?
SN 2006gy was an extremely energetic supernova that was discovered on September 18, 2006. Although about one hundred times as luminous as SN 1987A, which was bright enough to be seen by the naked eye, SN 2006gy was more than 1,400 times as far away as SN 1987A, and too far away to be seen without a telescope.SN1987A was a supernova in the outskirts of the Tarantula Nebula. It could be seen with the naked eye from the Southern Hemisphere.It was the closest observed supernova since SN 1604 The light from the supernova reached Earth on February 23, 1987.SN1604 was seen on October 9th, 1604 generally a supernova occurs once every fifty years but the universe has been in a drought for these supernatural awesome eventsSN1987A was a supernova in the outskirts of the Tarantula Nebula. It could be seen with the naked eye from the Southern Hemisphere.
Could a supernova on Jupiter cause the earth to be pushed off it axis?
Only a very, very few stars have mass enough to become supernova. Jupiter is a planet not a star. It is far to small to become a star, let alone a supernova.
Is far far away a place?
Far, far away is a saying that means something is literally far away.
