NASA Chandra X-Ray Observatory Detects 'Completely New Type of Cataclysmic Event'
A mysterious flash of X-rays probably ensuing from a "completely new kind of destructive event" in a house has been discovered by NASA's Chandra X-ray Observatory, a study says.
While the scientists believe the flash of X-rays, that stemmed from a faint, tiny galaxy regarding ten.7 billion lightweight years from Earth, doubtless comes from some kind of harmful event, they're unsure what caused it.
"We could have ascertained a totally new kind of destructive event," same study author Kevin Schawinski, of ETH urban centre (Swiss Federal Institute of Technology in Zurich) in Schweiz. Whatever it's, lots a lot of observations area unit required to figure out what we're seeing," Schawinski additional.
The X-ray supply, set in a very region of the sky called the Chandra Deep Field-South (CDF-S), has exceptional properties.
Prior to Oct 2014, this supply wasn't detected in X-rays, then again it erupted and have become a minimum of an element of one,000 brighter in very few hours. After a couple of days, the supply had pale utterly below the sensitivity of Chandra.
Thousands of hours of bequest information from the astrophysicist and Spitzer house Telescopes helped verify that the event doubtless came from a faint, tiny galaxy regarding ten.7 billion lightweight years from Earth.
For a number of minutes, the X-ray supply created m times a lot of energy than all the celebrities during this galaxy, same the study printed on-line within the journal Monthly Notices of the Royal Astronomical Society. Ever since discovering this supply, we've been troubled to know its origin," same Franz Bauer of the Pontifical Catholic University of Chile in Santiago.
"It's like we've a puzzle, however, we do not have all of the items," Bauer additional.
There area unit 3 main potentialities to clarify the X-ray supply, in step with scientists.
Two of them invoke gamma-ray burst (GRB) events that area unit jetted explosions triggered either by the collapse of a vast star or by the merger of a star with another star or a region.
If the jet is informed towards the world, a burst of gamma rays is detected. because the jet expands, it loses energy and produces weaker, a lot of identical radiation at X-ray and different wavelengths.
Possible explanations for the CDF-S X-ray supply, in step with the researchers, area unit a GRB that's not pointed toward Earth, or a GRB that lies on the far side the tiny galaxy. A third chance is that a medium-sized region chopped a star.
None of those concepts fits the information dead, once more} again, we've seldom if ever seen any of the projected potentialities in actual information, thus we do not perceive them well in the least," study author Ezequiel Treister, conjointly of the Pontifical Catholic University, noted.
