(These are seen only in spiral galaxies,… Read More; cosmic rays. Supernova - Supernova - Type I supernovae: Type I supernovae can be divided into three subgroups—Ia, Ib, and Ic—on the basis of their spectra. They are classified as supernova I and II, depending on their solar luminosities. (What kind of companion star is best suited to produce Type Ia supernovae is hotly debated.) Astronomer Johannes Kepler started observing the supernova on 17 th October 1607 and hence, it is named as SN 1604. The latest observed supernova was in Andromeda Galaxy in 1885 and is known as S Andromedae.
26. Type 1a supernova 1994D exploded near the outskirts of galaxy NGC 4526. Type I supernova has a peaked maxima (about 10 billion luminosities) and then gradually disappears. In supernova: Type II supernovae. Type Ia. These result from some binary star systems in which a carbon-oxygen white dwarf is accreting matter from a companion. It is the largest explosion that takes place in space. A supernova is a large explosion that takes place at the end of a star's life cycle.

A supernova is the explosion of a star. (Grades 5-8) series.

This article is part of the NASA Knows! On the left is Supernova 1987A after the star has exploded. The so-called classic explosion, associated with Type II supernovae, has as progenitor a very massive star (a Population I star) of at least eight solar masses that is at the end of its active lifetime. Supernova Facts: 26-30. A supernova (/ ˌ s uː p ər ˈ n oʊ v ə / plural: supernovae / ˌ s uː p ər ˈ n oʊ v iː / or supernovas, abbreviations: SN and SNe) is a powerful and luminous stellar explosion.This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. Type I supernova is further divided into Type Ia and […] The last known supernova explosion in our galaxy Milky Way was SN 1604. On the right is the star before it exploded.
