[00:00:00]Imagine a star so massive it makes the sun look almost weightless.

[00:00:04]This is R136a1.

[00:00:06]It sits about 160,000 light years away inside the [music] Tarantula Nebula in the Large Magellanic Cloud.

[00:00:13]And it is one of the most massive stars ever found. Current estimates place it at more than 200 times the mass of the sun.

[00:00:21]But it is not the biggest star by size.

[00:00:23]It is one of the most massive because it contains an extreme amount of material.

[00:00:27]A star like this burns through its fuel violently fast. While the sun can live for billions of years, stars like R136a1 may survive only a few million.

[00:00:38]The bigger the star, the shorter the life. R136a1 is not just a giant. It is a reminder that the brightest stars often die the fastest.
