Data from NASA’s Hubble Space Telescope have helped Astronomers establish the fact that dual clusters of humongous stars may be in the early stages of a collision. Astronomers are of the opinion the two clusters are 170,000 light years away in what is known as Large Magellenic Cloud, a satellite galaxy close to the Milky Way will merge.
Initially it was believed it was only one cluster in 30 Doradus, the star forming region, but in depth data revealed the presence of two clusters differing in age by about 1 million years. For more than 25 million years the massive 30 Doradus complex has been an active region that forms stars and it is not known for how long this region will actively create stars.
At Space Telescope Science Institute in Baltimore, researchers Elena Sabbi and her team had begun their search on fast moving stars or runaway stars ejected from their nurseries since their formation. As studies continued, researchers noticed the cluster had the shape of two merging galaxies as opposed to a spherical shape.
This was detected when researchers were taking a look through Hubble at distribution of low-mass stars. Sabbi said, “Stars are supposed to form in clusters, but there are many young stars outside 30 Doradus that could not have formed where they are; they may have been ejected at a very high velocity from 30 Doradus itself”.
