NASA astronomers observe black hole hurling hot mass into space at jet speed
NASA's Chandra Observatory has observed that the black hole is emitting hot material into space at a speed greater than that of the speed of light.

NASA has recently observed that a black hole is emitting hot material into at a speed greater than speed of light. According to NASA’s Chandra Observatory, researchers t only caught black hole pulling material away from a close star but also hurling hot material at a speed of more than 80 percent of speed of light. stellar mass of black hole, which is about eight times mass of sun, showed a peculiar behaviour of ejecting material as jets.
According to official release, astromers observed that black hole along with its star companion named MAXI J1820+070, which is located at least 10,000 light-years away from Earth in Milky Way, blasts away some hot material from ‘ point of return’ and prohibits its entry. ejections are in form of short beams of materials or jets. Moreover, se jets are directed in opposite directions and are launched in along magnetic field lines.

astromers have also informed that new observation is based on previous studies on black hole. se jets are travelling away from black hole and towards earth from rth and south direction in 60 and 160 percent of speed of light, respectively.

study said, “se jets are pointed in opposite directions, launched from outside event horizon along magnetic field lines.” “ new foot of this black hole's behaviour is based on four observations obtained with Chandra in vember 2018 and February, May, and June of 2019, and reported in a paper led by Mathilde Espinasse of Université de Paris,” it ded.

‘Superluminal motion’
astromers have stated that materials moving farr from stellar-mass black hole is an example of ‘superluminal motion’. This phemen occurs when ‘something’ travels towards earth near speed of light and direction is closer to “our line of sight”. According to NASA, this implies that travel of object gives an “illusion” that it is faster than speed of light.
“A phemen that occurs when something travels towards us near speed of light, along a direction close to our line of sight. This means object travels almost as quickly towards us as light it generates, giving illusion that jet's motion is more rapid than speed of light,” study said.
