The Sun is the star at the center of the Solar System. It is a massive, ... The Sun does not have enough mass to explode as a supernova. Instead, when it runs out of ...
In approximately 300,000 years, WR 104, a triple star, is expected to explode in a supernova. It has been suggested that it may produce a gamma ray burst that could pose a threat to life on Earth should its poles be aligned 12° or lower towards Earth. However spectroscopic observations now strongly suggest that it is tilted at an angle of 30 ...

These explosions — billions of times brighter than the sun — destroy the star, often leaving behind a black hole. Supernovas are also a useful tool for astronomers to measure distance.
Once a star like the Sun has exhausted its nuclear fuel, its core collapses into a dense white dwarf and the outer layers are expelled as a planetary nebula. Stars with around ten or more times the mass of the Sun can explode in a supernova as their inert iron cores collapse into an extremely dense neutron star or black hole.
The moon will appear to move in front of the sun beginning at 2:07 p.m. on April 8 in Rochester, New York. The window of totality is just 3 minutes and 38 seconds, with variance for location, and ...
A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate.
This combination of brightness and distance implies an extremely energetic source. Assuming the gamma-ray explosion to be spherical, the energy output of GRB 080319B would be within a factor of two of the rest-mass energy of the Sun (the energy which would be released were the Sun to be converted entirely into radiation).
