Space Supernova Hd Wallpapers Desktop And Mobile Images Photos Supernovae can expel several solar masses of material at speeds up to several percent of the speed of light. this drives an expanding shock wave into the surrounding interstellar medium, sweeping up an expanding shell of gas and dust observed as a supernova remnant. Astronomers captured a glimpse of the innermost layers of a massive star before it exploded in a supernova, changing their understanding of how stars evolve and die.
Supernova Remnant R Spaceengine For the first time, astrophysicists detected a supernova embedded in a wind rich with silicon, sulfur and argon. observations suggest the massive star lost its outer hydrogen and helium layers long before exploding. discovery offers direct evidence of the long theorized inner shell structure of massive stars.
. Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A supernova is what happens when a star has reached the end of its life and explodes in a brilliant burst of light. Supernova, any of a class of violently exploding stars whose luminosity after eruption suddenly increases many millions of times its normal level. the term supernova is derived from nova (latin: “new”), the name for another type of exploding star.

Supernovae are thus essential to life. after a core collapse supernova, all that remains is a dense core and hot gas called a nebula. when stars are especially large, the core collapses into a black hole. otherwise, the core becomes an ultra dense neutron star. A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe— black holes. the crab nebula is the leftover, or remnant, of a massive star in our milky way that died 6,500 light years away. Supernovas are some of the brightest events in the universe, occasionally outshining entire galaxies at their peak. many supernovas can be seen from billions of light years away, and nearby supernovas in past centuries have been visible during the daytime. A supernova is not just a star’s death—it is a dramatic event that reshapes the cosmos. these cosmic explosions are responsible for creating the elements that make up the earth and life itself, and they play a critical role in the evolution of galaxies and stars.
