The Hubble Space Telescope has revealed humongous stars on the farthest edges of the universe. These happen to be millions of times brighter than the sun.
The formation of massive stars remains a mystery. Some of them have been observed through the lens of the Hubble Space Telescope. The results of the study were published in the periodicals of the Royal Astronomical Society.

A mixed group of scientists used the NASA/ESA Hubble Space Telescope along with two other specialized observation tools to view the star cluster R136.
This cluster is a few light years in its span. However, it lies 170,000 light years away in the Tarantula Nebula. Many big and bright stars lie in the cluster.
They send forth energy and light in the ultraviolet range of the spectrum. The scientists observed these massive luminsescent stars in the UV range in order to get a better idea of them.
Many stars were spotted that were more than 50 solar masses in size. Over nine such stars were a hundred times as large as our sun. There is one of them which easily holds the record for being the most massive star in the universe. It is equal to 250 times as massive as the sun.
Together the cluster of big stars outshine the sun by a degree that equals 30 million. There were outflows from these huge stars. These stars discard an amount of material per month equal to the mass of the earth.
This waste matter is ejected at 1% of the speed of light which is still a very fast speed. Thus the stars lose a lot of weight throughout their life spans.
The difference of UV light found in some stars in comparison with the ordinary light of others was noted down well by the instruments that were on board the Hubble Space Telescope.
Some of the astronauts of NASA have played a crucial role in the discoveries we are seeing today. Their pivotal place in the pantheon of all-time geniuses and great individuals cannot be emphasized enough.
Five years ago, the existence of four stars in the cluster having 150 times the mass of the sun was noted down. It was not just a surprise but a genuine shock.

It has been said that these monster stars are produced from the amalgamation of several smaller stars. However, this theory fails in half the cases that have appeared before us. Star formation remains a mysterious process that is still not fully understood.
