NASA's Hubble Space Telescope also took images of the supernova's host galaxy — NGC 1309, located 110 million light-years away — in 2005, 2006 and 2010 before the explosion took place. Type II supernovae are distinguished from other types of supernovae by the presence of hydrogen in their spectra. However, current computer modeling suggests that a core bounce does not quite provide enough energy to power a supernova, there must be more to it. For more information on how nothing is sometimes leftover, read the following article: Can a Star Explode without Leaving any Remnant?

One possible scenario for this system the researchers modeled is that it originally consisted of two stars — one weighing four times the mass of the sun, and the other seven times the mass of the sun. You don’t have a Christian Science Monitor Instead, this Type Iax supernova resembles a nova star explosion — a much-less-powerful stellar blast — called V445 Puppis, an explosion in the Milky Way that astronomers detected in 2000. It is estimated that tens of thousands of these tiny particles pass through the human body every second of every day over the course of our entire lives. –20 < M > 160 Will end with a supernova and a black hole. The maxima may be about 10 billion solar luminosities. They do interact with normal matter, but quite infrequently.

Type II supernovae are not observed to occur in elliptical galaxies, and are thought to occur in Population I type stars in the spiral arms of galaxies.
