The other type, known as supermassive black holes, which are approximately a million more extensive than the Sun, and it is unknown how they formed.
The galaxy is called NGC 6240 and it's around 300 million light-years away but is still considered a neighbour more or less.
"But the black hole we have observed is more than 50 per cent larger than this limit". Researchers named the monster black hole LB-1.
"This newly discovered black hole is a young black hole, at most a few million years old, and is in our 'neighbourhood, ' unlike the old and remote black holes detected by LIGO", Professor Heger said.
Back in April, scientists unveiled what was believed to be the first ever picture of a black hole, which comes from data collected by the Event Horizon Telescope (EHT) - an worldwide project that connects dozens of observatories to capture the first image of a black hole by essentially creating a "virtual Earth-sized telescope". Follow-up observations with telescopes in Spain and the US led to the discovery of a star about eight times larger than the sun orbiting the black hole every 79 days.
The discovery was reported by the scientists in Nature magazine.
However researchers believed that typical stars within the Milky Manner shed most of their gasoline by stellar winds, stopping the emergence of a black gap the scale of LB-1, Liu stated.
However, the discovery of the huge black hole by an global team, led by scientists at the National Astronomical Observatory of China of the Chinese Academy of Sciences (NAOC), has toppled that assumption.
'Dim holes of such mass might perhaps presumably mute now now not even exist in our galaxy, per different the novel units of stellar evolution, ' he added.
Stellar black holes are normally fashioned within the aftermath of supernova explosions, a phenomenon that happens when extraordinarily giant stars burn out on the finish of their lives.
Researchers surveyed the sky to look for theses invisible objects using China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST).
This observational technique was first proposed by the visionary English scientist John Michell in 1783, but it has only become feasible with recent technological improvements in telescopes and detectors.
There is another black hole of the same mass range is detected, clocking in at around 62 solar masses - it was created as a result of a collision between two black holes in a binary pair - GW150914, the first direct detection of gravitational waves ever made by humans. The former turned out to be eight times the mass of the sun, orbiting a 70-solar-mass black hole every 79 days.
Now, a group of Chinese astronomers think they've found a star-and-black-hole pair another way. They performed follow up observations using the Gran Telescopio Canarias in Spain and the Keck Telescope in the U.S. In total, they performed 26 observations, involving 3,000 targets to find the black hole.
CBS cites a press release, and reveals that "such a search is like looking for the proverbial needle in a haystack: only one star in a thousand may be circling a black hole".
Black holes weighing between 1,000 and 100,000 Suns (so-called intermediate-mass black holes) may reside at the heart of small galaxies or in big star clusters.
How they're formed is mute poorly understood.
