IMBHs are a long-sought "missing link" in black hole evolution.
IMBHs are a little hard to identify as they are smaller in size and are less active than the supermassive black holes, as well as have a weaker gravitational pull, which means that they can't be easily spotted gozzling up other stars.
"Intermediate mass black holes are very elusive objects, and so it is critical to carefully consider and rule out alternative explanations for each candidate, said Dr Dacheng Lin, from the University of New Hampshire in Durham, US, who led the study".
"That is what Hubble has allowed us to do for our candidate", he further said.
Hubble Space Telescope has spotted an elusive black hole that almost 50,000 times the mass of our Sun.

Many salons and spas have already closed, Henry said, but the order encompasses any that were still operating. Other businesses can stay open, said Henry, as long as they can maintain proper social distancing.
Webb further said, "This will help us to understand what type of star was damaged by the black hole".
Weighing in at concerning 50,000 times the mass of our Sun, the black hole is smaller sized than the supermassive great voids (at millions or billions of solar masses) that lie at the cores of large galaxies, yet larger than stellar-mass great voids developed by the collapse of a massive star.
The second step was to determine if it had not come from a neutron star in our very own Milky Way galaxy but then again, neutron stars are way very dense remnants of an exploding star.
The huge mirror of NASA's James Webb Space Telescope - its successor to Hubble - has been successfully tested for the first time, putting it one step closer to its eventual launch, which is slated for 2021. Deep, high-resolution imaging supplies strong proof that the X-rays originated not from an isolated source in our galaxy, but instead in a remote, dense galaxy on the borders of one more galaxy- just the sort of location astronomers anticipated to find an IMBH.
As the names of the probes suggest, the academics were drawn to 3XMM J215022.4-055108 after spotting a burst of radiation that appeared to be the result of a star wandering too close to a black hole. Inside, they explain, there would be a black hole that recently had the opportunity to sit at the table. The object, called HLX-1, was spotted on the edge of a galaxy known as ESO 243-49 - and also resides in a star cluster that could have been a dwarf galaxy in the ancient past.
Astronomers, therefore, have to catch an IMBH red-handed in the relatively rare act of gobbling up a star. If this discovery holds, it will present astrophysicists with the lengthy-wanted lacking hyperlink in theories of black hole evolution. Lin and his colleagues combed through the XMM-Newton data archive, searching hundreds of thousands of sources to find this one IMBH candidate.
Finding this IMBH opens the door to the possibility of many more lurking undetected in the dark, waiting to be given away by a star passing too close. How do IMBHs themselves form? But seeing the object tearing a star apart makes this detection the strongest yet, according to the Dr Lin's team.
