An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . SUPERNOVA 1987a . This Hubble Space Telescope image shows the remnant of a supernova a star that blew itself to pieces. We first saw the light of the explosion on Earth in 1987, and this image was taken in 1994. The remnant of the explosion itself is the blob of stuff in the center; the rings are regions of material ejected by the star earlier in its death throes. ... Return to An Ancient Universe . ...

... Supernovae physics (from Wikipedia ): A supernova is a stellar explosion that creates an extremely luminous object that is initially made of plasma ionized form of matter. ... The explosion expels much or all of a star's material at a velocity of up to a tenth the speed of light, driving a shock wave into the surrounding interstellar gas. ... Working on a time series of images in the Large Magellanic Cloud he detected a flaring star, possibly a supernova located in a distant galaxy behind the LMC. ...

When most people think of a supernova (SN), they picture a single massive star exploding. ... The way the physics works, if the supernova expels more than half the total mass of both stars combined, the two stars will fly apart. For example, let's say the star that blows up masses 10 times the Sun's mass, and the companion masses twice the Sun. ...
