Black hole emits fire consuming cosmic Spaghetti: Study
What is Spaghettification
Black hole emits fire consuming cosmic Spaghetti: Study –When an object approaches a black hole, they become elongated under massive gravitational force – an event which is known as “spaghettification.” The black hole then swallows its cosmic meal, before finally emitting a loose massive fire.
Let’s understand the phenomenon
This is the first time that the scientists have recorded this volatile event. By examining the infrared light from the black hole disruptions, which was captured and “echoed” by the surrounding space dust, two different research teams measured the intensity of the blaze.
“The black hole destroyed everything between itself and the dust shell,” lead author Sjoert van Velzen, a postdoctoral fellow at the Johns Hopkins University, said. “It is as though the black hole cleaned its room by throwing those flames.”
A star being consumed by a massive black hole
Whenever a black hole consumes a star, it releases a huge amount of energy. This phenomenon is known as a “stellar tidal disruption,” which produces bright blaze surrounding the black hole’s phenomenon horizon. Few of such events have been described in the recent years, but they were not able to provide details beyond the mechanics of the activity.
These Black hole blazes are loaded with the X-ray and ultraviolet radiations, which vaporize dust and the other small pieces of matter.
But those particles can survive the radiation only at a certain distance, leaving a shell of the superheated dust, a few trillion miles away from the black hole’s center.
The surviving dust itself gives off the infrared radiation, echoing the blaze. This infrared outburst can be detected up to a year after the blaze hits its brightest peak, say the researchers.
By using the data from NASA’s Wide-field Infrared Survey Explorer (WISE), the researchers were able to capture the “light echoes”, and by measuring the delay between the original eruption and the infrared copy they could finally determine the distance between that black hole and the dust.
The WISE spacecraft performs a scans in every six months, so these researchers were able to capture those gradual changes in the emission.
This technique known as a photo-reverberation, allows the scientists to grab new information about the stellar tidal disruptions and the location of dust circles around the black holes.
“This study of ours confirms that the dust is there and that we can use it to determine the amount of energy generated in the destruction of a star,” co-author Varoujan Gorjian, an astronomer at NASA’s Jet Propulsion Laboratory, said.
