NASA's Hubble Space Telescope captured an astounding image of spiral galaxy NGC 4051
The Galaxy lies 45 million light-years from Earth in the southern part of Ursa Major I Cluster. There have been several supernova hosts.
The first was discovered in 1983 (SN 1983I), followed by another two decades later (SN 2003ie).
Both are categorized as Type Ic supernovae produced by the nuclear collapse of a massive star that lost its outer layer of hydrogen and helium either by wind or mass transfer to a
A third supernova was registered in 2010 (SN 2010br ).
All three events, according to NASA, were seen scattered throughout the middle and spiral arms of NGC 4051, which sits in the southern part of Ursa Major I Cluster.
"Especially rich in n spirals," according to NASA, Ursa Major is a subset of the larger Virgin Supercluster, which also houses the Milky Way.
Supernovae occurs in the last stages of a star's life after it has burned through its entire hydrogen and has moved on to helium. If it is massive enough, the star can begin to melt other elements such as carbon, neon, oxygen and silicon.
Finally, the core can grow so large that it cannot support its own mass, and as a balloon inflated past its breakpoint – the core suddenly collapses and creates a shockwave that causes the rest of the star to explode in a supernova .
The detonation can become so light that it briefly releases the star's entire homosexual axis. In fact, explosive light and material outbreaks in our Milky Way have been mistaken for new stars, where no one apparently existed before.
If the original star was big enough, the dense core could collapse under its own gravity and become black hole.
