Scientists studying black holes using the Hubble Space Telescope have detected infant stars orbiting the only black hole in the medium mass range (20,000 solar masses). Located near the edge of distant galaxy ESO 243-49, this mid-sized black hole called HLX-1, was first detected three years ago by Sean Farrell and his trustworthy team of scientists.

Scientists believe the presence of infant stars could point to this medium mass black hole once being located at the center of a dwarf galaxy torn apart by a collision with a larger galaxy. They also believe this news could possibly be linked to the way black holes and galaxies are born in the universe.

The team of astronomers studying black holes with a mass near ten solar masses have some understanding of the nature of these medium weight monsters. They would like to gain a better understanding of mid-sized black holes or the gigantic monsters they believe could reside in the center of galaxies.

Scientists studying the formation of black holes and galaxies believe it could also be possible bigger black holes are formed during a process in which two black holes combine in some amazing way.

Farrell and his team of scientists have since this time been studying HLX-1 using various astronomical techniques and stellar instruments. They and other scientists believe the data collected, and the computers simulations they have conducted, could indicate the presence of infant stars orbiting HLX-1.

The best explanation scientists have for the birth of the infant stars orbiting HXL-1 is during the collision between its possible parent dwarf galaxy and a larger galaxy. They also believe they might be able to get an estimate on how long ago it was since the two galaxies collided in space by determining the age of the infant stars.

As for the medium size black hole HLX-1, astronomers at this point really have no clue as to its final destiny. You can bet they would love to stick around for the millions of years it will take for this drama to play out? They believe it might be possible one day it will combine with the giant black hole in the center of the galaxy. It might even just settle down into a stable orbit. The only thing they think will happen for sure is it will eventually fade from the view of our astronomical instruments.
