Recently a team of astronomers have captured images of an explosive star birth about 1,500 light years away from Earth. Around 500 years ago, a pair of adolescent protostars had a perilously close encounter that caused a huge blast and tore their stellar nursery apart.
Using Atacama Large Sub Millimeter Array (ALMA) telescope in Chile, the astronomers have collected data about this explosive star. The Orion Molecular Cloud 1 (OMC-1) about 100,000 years ago had several protostars that started to form and caused the formation of a system of active stars behind the Orion nebula attached to each other by their gravitational force and drew closer with passing time. Eventually, this lead to a huge collision among two of these massive stars which caused a heavy explosion that send other protostars and hundreds of giant streamers of dust into the space at speeds greater than 150 kilometer per second. This collision generated the amount of energy that our sun generates in a time span of over 10 million years. The left over pieces of this explosion is visible from Earth today. John Bally from the University of Colorado said, “What we see in this one calm stellar nursery is a cosmic version of a 4th of July fireworks display with giant streamers rocketing off in all directions. By destroying their parent cloud, as we see in OMC-1, such explosions may also help to regulate the pace of star formation in these giant molecular clouds.” It is considered that these random motions of the protostars after the explosion can allow some of the stars to fall towards a common center of gravity which can create violent interactions in future.
