Most Massive Star Ever

This is interesting; according to an article published in The Great Beyond astronomers discovered a cluster of super massive stars, up to 300 times the solar mass and 10 million times more luminous than the Sun. According to the official press release this massive star would outshine the sun in the same way as the sun outshines the full moon.

Scientists are not certain if those massive stars were born big or were they the result of several massive stars merging. However they were formed, very impressive, but as we know, big stars don't last very long. In a few million years we should be able to observe a huge type II Supernova. Yes, our Sun will outlast those huge stars by billions of years, so someone here on Earth should be able to make the observation.
