Astronomers Think A Cosmic Zombie Is on the Loose

 

Astronomers think there could be a “cosmic zombie” on the loose in the galaxy due to the reason that usually when a supernova occurs, it wipes out the igniting white dwarf star which happens to be unlucky enough to be trapped in the middle of it. However it appears with the discovery of what scientists have found, this may mean a few white dwarfs endure through their own personal apocalypses and leave behind what NASA has designated as possible zombie stars.

A group of astronomers searched through information taken from the Hubble Space Telescope and discovered a star that looked as if it survived a frail supernova. This kind of supernova is known as a Type Iax. The type is not to be mixed up with brighter supernovas which are called Type Ia. The zombie creating supernova has been given the title SN 2012Z. It is located around 110 million light years away from the Earth.

The Hubble was able to capture images of the star’s host galaxy a number of years before the supernova happened, therefore giving astrophysicists both a before and an after observation of the occurrence. When they discovered the remnant of the star, it was described as being one of those “ah-ha moments.”

Curtis McCully, who is a graduate student and also the chief journalist of one of the papers written about the zombie star, stated that he and his astronomy team were extremely shocked to see anything at the site of the supernova. They thought the system would be much too dim to see, like in prior searches for usual Type la supernova progenitors. He added that it was exciting when nature ended up surprising researchers. His investigation report is scheduled to appear in the next edition of the science journal Nature.

The reality of a zombie star is presently considered a theory. However astronomers are hoping that further interpretations of the region in 2015, after the light dimmed from the supernova, will sanction the finding. The zombie star might have numerous others just like it in the cosmos. Astronomers have at present found at least 30 mini-supernovas that are possible white dwarfs. That alone may not be enough to meet the requirements to be considered a zombie star but it is probably getting close.

Repeating: apparently there could be a “cosmic zombie” on the loose in the galaxy. This is because usually when a supernova occurs, it wipes out the igniting white dwarf star that happens to be unlucky enough to be trapped in the middle of it. However it appears that with the discovery of the zombie, a few stars might endure through their own particular apocalypses and leave behind what NASA has designated as zombie stars.
