SN 2006gy [See Link] 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 [See Link]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 [See Link] 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 events
Supernovas are the explosions of large stars in space.
no
Stars do not create supernovas. Supernovas happen to stars. A supernova is when a star, bigger than our own sun, explodes due to the lack of gas they need.
Astronomers over many years have observed different stars. They have observed a creation of a new star (not really but like one day there will be nothing, the next maybe a small gleam and eventually a star) and the death of a star (supernovas, collapsion)
Star Dust from supernovas is what makes technically 'everything' in the Universe.
They are not. A supernova is an explosion of a star. Blue stars usually end their lives in such explosions.
In space.
A great energy and light is produced by the supernovas. Therefore, a great number of photons is produced.
Christmas is usually observed on December 25, though some countries may observe it on other days.
