Supernovae are very violent events resulting at the "death" of a star. Typically, they are detected by the very large amounts of radiation energies they release. Supernovae release beams of X-ray and Gamma radiation which instruments like telescopes and special satellites near Earth can detect. The creation of one also releases a great amount of visible light (unlike something like a black hole, for example, which is impossible to see with the naked eye but releases enormous amounts of other radiation that are obvious to special observation equipment).
What else can I help you with?
When was the earliest detected Supernova?
The earliest recorded supernova was observed by the ancient Chinese astronomers in 185 AD. The supernova, now known as SN 185, was visible in the night sky for several months.
How did supernova SN 1987A differ from most other observed supernovae?
Supernova SN 1987A was the closest observed supernova to Earth in almost 400 years, allowing for detailed observations. It was also the first naked-eye supernova since the invention of the telescope. Additionally, SN 1987A marked the first time neutrinos were detected coming from a supernova, which provided valuable insights into the explosion process.
How many gamma rays travel after a supernova?
Gamma rays from a supernova can travel vast distances, potentially out to light-years away from the source. They can be detected by astronomers on Earth using specialized instruments, giving us valuable insights into the explosion and its aftermath.
How many neutrinos from supernova SN 1987A were detected on Earth?
There are somewhere around 65 billion neutrinos per second passing through every square centimeter perpendicular to the Sun. By far the majority of those also come out the other side... baryonic matter is essentially transparent to neutrinos.
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 is the adverb phrase of a black hole is the remains of a supermassive star after a supernova?
"after a supernova" is the adverb phrase in the sentence.
How did supernova 1987 get its name?
The name is formed from SN (yes SuperNova), the year of discovery, then followed by a one or two letter designation. SN is optional.The first 26 of the year get designated with an upper case letter from A to Z. then, pairs of lowercase letters are used, starting with aa, ab.... etcetera Historical supernovae were known simply by the year they occurred: SN185, SN1572 SN1604. Since 1885, the letter notation was used.
What gives a star light?
supernova supernova
When was Supernova released?
Supernova was released on 01/14/2000.
What was the Production Budget for Supernova?
The Production Budget for Supernova was $60,000,000.
What is the name of an explodeing star?
It's Called A Supernova
What is the name for a supernova cloud?
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
