Indian Scientists Discover Rare Black Hole: In a recent study published by Monthly Notices of The Royal Astronomical Society, Indian scientists discovered a supermassive black hole in space.
The enormous black hole is located about a billion light years from Earth.
The black was discovered spewing jets of fire in a single direction, which has created quite a stir in the scientific community as only one side of the jet of fire is visible.
Although it is common for supermassive black holes to emit strong jets of radiation and particles, this black hole is quite an enigma. As the jets emitted by black holes are always launched in pairs and move in opposite directions at incredible speeds.
This rare “dragon” black hole is located in the galaxy RAD12 and launches fireballs at another galaxy called RAD 12b.

RAD 12b is an elliptical galaxy, larger and brighter than RAD 12. In the next billion years or so, the two aforementioned galaxies will merge into one larger galaxy.
The jet emitted by the black hole is larger than RAD 12, its host. According to the study, it is located about 440,000 light years away and is shaped like a mushroom.
The thrown jet bounces back to its host black hole after colliding with RAD 12b.
In 2013, distinctive features of RAD12 were identified using optical data from the Sloan Digitized Sky Survey (SDSS) and radio data from the Very Large Array.
To demonstrate that the features of the galaxy and its enormous black hole were unique, scientists conducted additional observations with the Giant Meter-Wave Radio Telescope (GMRT), located in India.
This is the first time a jet has been seen colliding with a massive galaxy like RAD12-B, making RAD12 unlike anything discovered to date. Beyond the visible RAD12 stars, a conical stalk of premature plasma can be seen being ejected from the core, where the black hole is located.

Black holes are objects in space with enormous mass and density that bend space and time. They are massive objects that have their own gravitational pull.
The gravitational pull of a black hole is so strong that once an object is pulled in, nothing, not even light (the fastest in the entire known universe) can escape it.
How are black holes formed?
Albert Einstein formulated a theory hundreds of years ago that remains true even today. He said that energy cannot be created or destroyed, it can only be changed from one form to another.
Likewise, black holes do not emerge from nowhere, but rather their beginnings are marked by the end of massive celestial bodies.
When a massive star explodes and goes supernova, it leaves behind a small, dense residual core as it dies.
If the mass of the core exceeds approximately three times that of the Sun, gravity will prevail over all other natural forces and lead to the formation of a black hole.

This discovery may help investigate why star formation is nonexistent in elliptical galaxies, especially those with massive black holes at their centers.
