The Supernova Group at the Center for Astrophysics | Harvard & Smithsonian has cataloged thousands of supernova “light curves”: the increase and decrease of light emission during and after the explosion. These light curves are helpful for identifying the atoms and molecules present in the supernova, measuring the distance to the supernova ...
Keplers supernova med navnet SN 1604, hvis eksplosion kunne ses på jorden i 1604. Da SN 1604 er ca. 20.000 lysår fra jorden skete eksplosionen i år 1604-20.000. Billedet er fra ca. 2004 og supernovarestens sky set i jordens afstand er ca. 14 lysår bred og er med nogle "falske" farver, da det er sammensat af 3 billeder med "farverne ...
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. As these stars burn the fuel in their cores, they produce heat. This heat produces pressure that pushes outward against the forces of ...
Type Ia supernova. At the core of a planetary nebula, Henize 2-428, two white dwarf stars slightly under one solar mass each are expected to merge and create a Type Ia supernova destroying both in about 700 million years (artist's impression). A Type Ia supernova (read: "type one-A") is a type of supernova that occurs in binary systems (two ...
Supernova on tähden räjähdys, joka voi syntyä kahdella eri tavalla. Massiivinen tähti voi luhistua fuusion loputtua oman painovoimansa johdosta neutronitähdeksi tai mustaksi aukoksi tai kaksoistähdissä valkoinen kääpiö voi kasvattaa massaansa yli Chandrasekharin rajan. [1] Supernovia esiintyy keskimäärin 50 vuoden välein linnunradan kokoisissa galakseissa. [1] [2] Kun ennen ...

Sep 23, 2021 · In 1987, there was a supernova explosion in the Large Magellanic Cloud, a companion galaxy to the Milky Way. Supernova 1987A, which is shown at the top of the page, is close enough to continuously observe as it changes over time, thus greatly expanding astronomers' understanding of this fascinating phenomenon.
