    The supranova model for gamma-ray bursts, originally proposed by Vietri & Stella (1998), has several unique features that make it attractive for the interpretation of GRBs and their afterglows, and it has emerged as a promising candidate for modeling the evolution and environment of at least some GRB sources.

    One type of supernova is caused by the “last hurrah” of a dying massive star. This happens when a star at least five times the mass of our sun goes out with a fantastic bang! Massive stars burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of energy, so the center gets very hot. Heat generates pressure, and the pressur...

    These spectacular events can be so bright that they outshine their entire galaxies for a few days or even months. They can be seen across the universe.

    Not very. Astronomers believe that about two or three supernovas occur each century in galaxies like our own Milky Way. Because the universe contains so many galaxies, astronomers observe a few hundred supernovas per year outside our galaxy. Space dust blocks our view of most of the supernovas within the Milky Way.

    Scientists have learned a lot about the universe by studying supernovas. They use the second type of supernova (the kind involving white dwarfs) like a ruler, to measure distances in space. They have also learned that stars are the universe’s factories. Stars generate the chemical elements needed to make everything in our universe. At their cores, ...

    NASA scientists use a number of different types of telescopes to search for and then study supernovas. One example is the NuSTAR (Nuclear Spectroscopic Telescope Array) mission, which uses X-ray vision to investigate the universe. NuSTAR is helping scientists observe supernovas and young nebulas to learn more about what happens leading up to, durin...

    A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun.

    Jun 15, 2024 · 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 resemble novae in several respects.
