Star Cluster R136
The image shows the central region of the Tarantula Nebula in the Large Magellanic Cloud. The young and dense star cluster R136 can be seen at the lower right of the image. This cluster contains hundreds of young, blue stars, among them the most massive stars detected in the universe so far. Astronomers using NASA's Hubble Space Telescope were able to conduct a detailed imaging and spectroscopic study of the central and most dense region of this cluster. Here they found nine stars with masses greater than 100 times the mass of the sun. The cluster is located 170,000 light-years away from Earth.
