What Is a Supernova NASA ~ A supernova happens where there is a change in the core or center of a star A change can occur in two different ways with both resulting in a supernova The first type of supernova happens in binary star systems Binary stars are two stars that orbit the same point

Supernovae Information and Facts National Geographic ~ These stars end their evolutions in massive cosmic explosions known as supernovae When supernovae explode they jettison matter into space at some 9000 to 25000 miles 15000 to 40000

List of supernova candidates Wikipedia ~ Type II supernova progenitors include stars with at least 10 solar masses that are in the final stages of their evolution Prominent examples of stars in this mass range include Antares Spica Gamma Velorum Mu Cephei and members of the Quintuplet Cluster

What Is a Supernova Discovery Death and Explosions Space ~ Type Ia supernovae are generally thought to originate from white dwarf stars in a close binary system As the gas of the companion star accumulates onto the white dwarf the white dwarf

supernova Definition Types Facts Britannica ~ Supernova any of a class of violently exploding stars whose luminosity after eruption suddenly increases many millions of times its normal level When a star ‘goes supernova’ considerable amounts of matter may be blasted into space with such a burst of energy as to enable the star to outshine its entire home galaxy

Supernovae The Deaths of Massive Stars ~ Supernovae come in two flavors Type 1 and Type II with subtypes such as Ia and IIa A supernova explosion often blows a star apart leaving behind a massive core Some supernova explosions result in the creation of stellarmass black holes Stars like the Sun do NOT die as supernovae

Betelgeuse Supernova or Fading Star Answers in Genesis ~ According to theories of stellar evolution massive stars such as Betelgeuse end up as red supergiants just before exploding as supernovae The process of becoming a supernova supposedly is presaged by increasing instability

What Is a Supernova NASA Space Place – NASA Science for ~ 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 6500 lightyears away

Supernova Wikipedia ~ Type Ibc and IIL and possibly most Type IIn supernovae are only thought to be produced from stars having nearsolar metallicity levels that result in high mass loss from massive stars hence they are less common in older moredistant galaxies

Betelgeuse The Eventual Supernova Space ~ Betelgeuse is a star nearing the end of its life Because it is creating heavier and heavier elements in its core that could be used for stars after it dies a NASA story once dubbed the red giant a workaholic The star is a famous one among amateur astronomers not only for its size and brightness
