THE STAR THAT WAS OUSTED

When news first came out from NASA about an amalgam of stars that were kicked out of the galaxy by a gigantic black hole, it sparked intrigue. However, the news about the star was soon accompanied by the ousted supernova which it eventually turned into.

In lieu of this news that was released on the 13th of August, a paper was published with the findings of the phenomenon in Monthly Notices of the Royal Astronomical Society. The findings include the author’s theory on the origins of the outcast supernova.

LEARNING MORE ABOUT THE OUTCAST SUPERNOVA

What is known about it is that the stars were flung out of the Milky Way by the gigantic black hole to where it say outside the system at a fast rate. However what was an interesting observation was that in studying the Hubble’s older images of the stars speeding to the outskirts was that the galaxies around were old and mergers.

Additionally, the location of the supernova indicated the stars that formed the supernova were old as well. Following this line of thought, the supernova may have had a companion, one that originally triggered the transition into supernova, becoming the outcast supernova the Hubble saw.

THE TRANSITION FROM BINARY STAR TO SUPERNOVA

Ryan Foley, the author of the aforementioned paper published a few days prior, theorized that a pair of black holes in merging galaxies could potentially create a slingshot effect to shoot the binary stars out into the universe just like it did with the outcast supernova. The process involves stars getting dragged into  a black hole toward the center of the galaxy, and then get precariously close to another, external black hole that flings the unfortunate stars out of the galaxy.

After the stars are flung out, they slowly move closer and closer together, speeding up all stellar bodies’ aging process. The reasoning is that the stars grouped together are mostly white dwarfs; quite old, and at such magnificent speeds one dwarf shreds another.

As the remnants of the shredded dwarf hit the remaining one, it triggers the explosion needed to create a supernova. Thus, we have the outcast supernova without the trademark mega-explosion one would expect.

This brings us to the more interesting of why these things occurred. To keep up with the latest findings of the Hubble Telescope, you can follow it here.

Origins of the Outcast Supernova

The beasts of the universe confirmed! - http://clapway.com/2015/07/08/millions-of-hidden-black-holes-may-exist-in-our-universe-164/

The notion that the universe is likely filled with millions of supermassive black holes is quite disconcerting, yet that is exactly the conclusion arrived at by several scientists who recently used NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) satellite and uncovered the existence of five supermassive black holes which they had previously been unable to see.

The Quest to Find Hidden Black Holes

The five supermassive black holes that the scientists uncovered had previously been obscured by enormous clouds of dust and gas. It is commonly understood that supermassive black holes exist at the center of large galaxies, but most of the time, scientists are unable to fully confirm their presence because they are covered by vast quantities of dust and gas that most telescopes are not capable of piercing through.

However, astronomers from Durham University in the United Kingdom who were conducting research on black holes were finally able to pierce through that veil. They achieved this when they aimed the NuSTAR satellite at nine galaxies and discovered that five of them had been hiding supermassive black holes at their centers.

Horrors Spread Across The Universe

Durham University’s George Lansbury, who led the study, stated, “Thanks to NuSTAR, for the first time, we have been able to clearly identify these hidden monsters that are predicted to be there, but have previously been elusive because of their surrounding cocoons of material.”

His team’s findings were presented in Llandudno, Wales, at the Royal Astronomical Society’s National Astronomy Meeting and published in The Astrophysical Journal. In a chilling statement, he added, “Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole universe then the predicted numbers are huge and in agreement with what we would expect to see.”

The Power of the NuSTAR

NASA’s Nuclear Stereoscopic Telescope Array (NuSTAR) satellite was launched in 2012 and detects black holes by searching for the highest-energy x-rays. These highest-energy x-rays are much stronger than typical x-rays and can therefore be detected by telescopes equipped to find them.

Daniel Stern, a scientist for NuSTAR at NASA’s Jet Propulsion Laboratory in Pasadena, California, said of NuSTAR that it “allows us to see how big the hidden monsters are, and is helping us learn why only some black holes appear obscured.”
