Scientists have found a new kind of black hole using CSIRO's Australia Telescope Compact Array. The blackhole, is not too big and not too small, falling in the class of "middleweight" black holes. The discovery indicates that black holes can take on a variety of sizes than previously assumed. They could also be the younger version of what it might become later on.

Scientists believed that black holes only came in two major varieties, supermassive ones and stellar mass ones. Supermassive ones can be found in the center of galaxies and have a million to billion times the mass of our sun and stellar mass ones are anywhere from three to 30 times our sun's mass.

Astronomers believe they have stumbled upon a black hole that's 20,000 to 90,000 times the mass of our sun, placing it in the intermediate class of black holes. Called HLX-1 ("hyper-luminous X-ray source 1"), the black hole is about 300 million light-years away. It was discovered by Natalie Webb from Université de Toulouse and her research team, which included astronomers from France, Australia, the UK and the USA.

Since this is the first black hole discovered of its kind, the astronomers are hoping to find more. You can check out the entire paper in Science.
