Astronomers did not only witness a supernova explosion in the Messier 82 Galaxy but also found a black hole 400 times the mass of the Earth's sun.

Black hole is a region in space containing a mass that is so dense that not even light can escape its gravity.

To find black holes, astronomers track gravitational pull of objects being sucked into the black hole because black holes are invisible.

Matter being pulled into a black hole gathers around it like storm debris circling a tornado's center, they explained.

As this cosmic stuff rubs together it produces friction and light transforming black holes into a very bright object, astronomers said.

Researchers spotted two repeating flares of lights circling the black hole which showed a rhythmic pattern of light pulses that occurs 5.1 times per second and 3.3 time per second.

Richard Mushotzky said that light oscillations were like two dust modes stuck in the grooves of a vinyl record spinning on a turntable.

If the oscillations were musical beats they would produce a specific syncopated rhythm, he explained.

Astronomers use a 3:2 oscillation of light to measure a black hole's mass which has been used to smaller black holes but was not used to intermediate-mass black holes.

Dheeraj Pasham said that using the oscillations they estimated the black hole that they named M82 X-1 to have 105 solar masses.

There is still a need to confirm the existence of this observation so that theorist can get to work, he said.

Last week, astronomers witnessed a supernova explosion that occurred in Messier Galaxy otherwise called the Cigar Galaxy.

Scientists believe that the explosion named SN 2014J explosion occurred when two white dwarfs in the galaxy merged.

The explosion was observed using the Chandra X-Ray Observatory, a space telescope made by NASA launched on July, 1999.
