Eye of Sauron measurements are being put into practice by space researchers this week based on a giant black hole. Called “Sauron” due to the massive structure set within an active galaxy that looks eerily similar to the red eye of destruction from the iconic “The Lord of the Rings” movies, this hole will be used as a measuring tool for big cosmic spaces. Travelers Today News shares this Friday, November 28, 2014, that the galaxy is currently being called NGC 4151, but might do with an apt nickname like “My Precious.”
They may not be to conquer Middle-earth, but Eye of Sauron measurements are still being put into full use as a valuable space tool for gauging distances this week. With this “Sauron” black hole in tow, scientists are going to have a more consistent way of trying to measure massive celestial expanses. The hole is deep within a far-off galaxy that appears somewhat comparable to Sauron’s ever-searching eye atop the tower of Barad-dur.
In order to get a grasp on how these researchers plan on taking advantage of the new technique, understanding a bit behind this measurement tool and how specifically black holes “perform” are of critical importance. As many scientists can tell you, gas out in space is always being absorbed at a rapid pace by black holes that are in active states. This gas reaches incredibly hot temperatures while being drawn in, and eventually looses a form of UV radiation. This gas is eventually then redistributed as heat, dust, and debris that continually orbits around the hole, making it seem bigger than ever.
“Using telescopes on Earth, we can now measure the time delay between the ultraviolet light from the black hole and the subsequent infrared radiation emitted from the dust cloud,” Darach Watson, who work as an astronomer and black hole expert at the University of Copenhagen. “The time difference is about 30 days and because we know the speed of light, we can calculate the real physical distance between the black hole and the encircling dust.”
It might not appear to have much practical significance, but this Eye of Sauron measurement technique using the galaxy’s black hole is important to space scientists and astronomers alike. A precise measuring method or system will allow experts to gauge vast distances in a more uniform, accurate way as a result. The press release provided via United Press International News goes on to share:
“We calculated the distance to be 62 million light years,” Watson added, once again alluding to the Eye of Sauron black hole. “The previous calculations based on redshift (a change in the wavelength of the light due to the velocity of the object away from us) were between 13 million and 95 million light years, so we have gone from a great deal of uncertainty to now being able to determine the precise distance.”
Ultimately, the emergence of this updated technique should give scientists a more thorough and defined grasp of several important aspects of these cosmos. Two of these include how quickly certain areas of the universe are enlarging at a given time and how large certain black holes or remote galaxies may truly be. The new approach to measuring distance in space is shared in the latest edition of the Nature journal, so it seems like more information about the mysteries of far-off phenomena are being unearthed each and every day.
These Eye of Sauron measurements aren’t the only interesting space tool in existence being examined by scientists this week. The discovery of an invisible force field around planet Earth has also been recently found by experts on the cosmos. Apparently, this powerful shield protects our atmosphere from the harmful radiation caused by superfast electrons and other particles bouncing through the space. One scientists compared the phenomenon to an encircling “glass wall” around the world.
