They also produce long-duration gamma-ray bursts, which are among the most energetic events observed in our universe. When it will happen, VY Canis Majoris will explode releasing the energy of more than times that of a supernova, and enormous quantities of gamma rays.
This explosion will not affect Earth as the hypergiant is too far away, but if there are any planets near VY Canis Majoris which host life, it would be completely eradicated. The hypernova explosion is estimated to take place in around After the star explodes, it is speculated that its remaining core will collapse and result in a black hole.
VY Canis Majoris is surrounded by a complex asymmetric circumstellar envelope caused by mass loss from the star itself. VY Canis Majoris is one of the largest known stars by radius, luminosity, and mass in regards to typical red giants. VY Canis Majoris has been estimated to have around 17 solar masses, but its radius is a whopping 1. The hypergiant is also around VY Canis Majoris is, in fact, cooler than our sun, with estimated surface temperatures of around 3.
One of the first recorded observations of VY Canis Majoris occurred in Most stars end their life in a supernova explosion, in the case of VY Canis Majoris, it will end its life in something around times greater than a supernova, a hypernova. VY Canis Majoris has been estimated to have around 8.
It is much younger than our sun. Did you know? If a car going with a speed of m. The white arrows and transparent circle show the general spherical flow of matter outward.

Although VY Can is about half a million times as luminous as the Sun, much of its visible light is absorbed by a large, asymmetric cloud of dust particles that has been ejected from the star in various outbursts over the past 1, years or so. The cloud then passes in front of the star, making it look much fainter.
The constellation hosts the brightest star in the night sky, Sirius. VY Canis Majoris is much fainter — to the eye, anyway. The star also is about times wider than the Sun. When they reach the surface, some of the gas flies out into space. It eventually cools and forms a cloud of dark dust.
That appears to have happened at least four times in the last years.
