a supernova is an stellar explosion extremely luminouse and cause a bright radiation.
I recommend for you to understand the supernova the link provided in the related links box below.
What else can I help you with?
How bright was the brightest supernova in the universe?
As of January 2016 the brightest supernova reported was ASSN SN 15lh. It had an absolute magnitude of - 23.5. For comparison, the absolute magnitude of the Sun is 4.83.
What is the magnitude of cassiopeiae?
Cassiopeia A is a supernova remnant in the constellation Cassiopeia.It has no single point of luminosity, so no definitive magnitude can be attributed to it.
What might you expect the peak apparent magnitude of the Betelgeuse supernova explosion to be?
Big
What is the magnitude of Cassiopeia A?
The magnitude of Cassiopeia A, a supernova remnant, varies depending on the wavelength observed. In visible light, its magnitude is around 12.2, making it too faint to be seen with the naked eye. At radio wavelengths, it is much brighter due to synchrotron radiation emitted by high-energy electrons.
What is the magnitude of SN 1604?
SN 1604, also known as Kepler's Supernova, had a peak apparent magnitude of about -2.5. This makes it one of the brightest supernovae observed in recorded history. Its absolute magnitude at peak brightness is estimated to be around -19.3, indicating its significant luminosity compared to typical stars.
What is the absolute magnitude of 1987A halo?
The absolute magnitude of the 1987A supernova shock halo is estimated to range between -9 to -10 magnitudes in the visible light spectrum. This value indicates the intrinsic brightness of the halo if it were observed from a standard distance of 10 parsecs (32.6 light-years).
How long does the process of a supernova take?
A supernova is when a massive star explodes.The first possible supernova was after the death of the first stars, which would have been about 13 billion years ago. The last supernova could have been today.
IS S Doradus going to exsplode?
Probably. It is an extremely bright star (a very high absolute magnitude), with a high mass, and such stars tend to end up as a supernova.
How many times bigger is a supernova than a nuclear explosion?
The lowest energy release in a supernova is about 1.5E44 Joules, the highest energy release in a nuclear explosion (i.e. the Soviet Tsar Bomba of 1961) was about 2.17E17 joules (although significantly larger yields are possible, nobody has seen any reason to build one).This is 27 orders of magnitude between the smallest supernova and the largest nuclear explosion that was ever done!!!
What is the stars absolute magnitude?
A star's "absolute magnitude" is a measure of its absolute (or real) brightness. It is defined as the "apparent magnitude" the star would have at a standard distance of 10 parsecs, which is equal to 32.6 light years.
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.
