R136a1
165,000 light-years from the Earth



R136a1 is believed to be the most massive star in the universe. In 2010, British astronomers in the University of Sheffield discovered the giant star in the Tarantula Nebula through a small satellite galaxy that circles the Milky Way.

While R136a1 is reported to be 265 times more massive than the Sun, it could have been 320 times more once, the discoverers noted. This star is also the most luminous.

It is believed to be 10 million times brighter than our sun and has a temperature of 40,000 degrees Celsius on its surface.

The R136a1 gives off more energy than all stars belonging in the Orion Nebula.

    “VY Canis is the largest star in the universe in terms of size”. Right! Maybe the largest known in the Milky Way. There are only about 400 billion galaxies in the known universe (a number that continues to grow), of which the Milky Way is the only one in which we can discern individual stars, so be careful how you state it.

      We are sorry, it’s true, the title is a misleading one. We cannot possibly know whether these stars are the biggest in the universe…
