Infant, 30-Year-Old Black Hole -Youngest Ever Discovered

Youngestnear It's estimated that there are millions of unseen black holes in the Milky Way. The ghosts of once massive stars. This composite image by astronomers using NASA's Chandra X-ray Observatoryby shows a supernova within the galaxy M100 that may contain the youngest known black hole in our cosmic neighborhood.

The 30-year-old black hole could help scientists better understand how massive stars explode, which ones leave behind black holes or neutron stars, and the number of black holes in our galaxy and others.
The 30-year-old object is a remnant of SN 1979C, a supernova in the galaxy M100 approximately 50 million light years from Earth.

Data from Chandra, NASA's Swift satellite, the European Space Agency's XMM-Newton and the German ROSAT observatory revealed a bright source of X-rays that has remained steady during observation from 1995 to 2007. This suggests the object is a black hole being fed either by material falling into it from the supernova or a binary companion.

"If our interpretation is correct, this is the nearest example where the birth of a black hole has been observed," said Daniel Patnaude of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. who led the study.

The scientists think SN 1979C, first discovered by an amateur astronomer in 1979, formed when a star about 20 times more massive than the sun collapsed. Many new black holes in the distant universe previously have been detected in the form of gamma-ray bursts (GRBs). However, SN 1979C is different because it is much closer and belongs to a class of supernovas unlikely to be associated with a GRB. Theory predicts most black holes in the universe should form when the core of a star collapses and a GRB is not produced.

"This may be the first time the common way of making a black hole has been observed," said co-author Abraham Loeb, also of the Harvard-Smithsonian Center for Astrophysics. "However, it is very difficult to detect this type of black hole birth because decades of X-ray observations are needed to make the case."

The idea of a black hole with an observed age of only about 30 years is consistent with recent theoretical work. In 2005, a theory was presented that the bright optical light of this supernova was powered by a jet from a black hole that was unable to penetrate the hydrogen envelope of the star to form a GRB. The results seen in the observations of SN 1979C fit this theory very well.

Although the evidence points to a newly formed black hole in SN 1979C, another intriguing possibility is that a young, rapidly spinning neutron star with a powerful wind of high energy particles could be responsible for the X-ray emission. This would make the object in SN 1979C the youngest and brightest example of such a "pulsar wind nebula" and the youngest known neutron star.

Comments

OF COURSE, NASA would NOT come out and say, "THIS IS PLANET X !"

But they would START by providing you with a piece of information that ENSURES that you will NEVER conclude it is Planet X, then at sometime in the future they will say, "Opps, we made a BOO BOO, that object is actually moving towards Earth VERY RAPIDLY !!!!!!"

By ensuring you can not call it Planet X they completely control the conversation and any new info about the object from then on.

IF you DO conclude it IS Planet X in-spite of what NASA claims then you don't need them to tell you what is going to happen next, thus, THEY STOP CONTROLLING YOU !!!
