... The way to get heat out of an interstellar cloud is for the particles that make up to cloud to collide with each other. In a collision between two particles (atoms or molecules or ions), one of the colliding partners loses some kinetic energy and the other picks it up. However, the gain in energy co ...

R136a1
RMC 136a1 (usually abbreviated to R136a1) is a Wolf-Rayet star located at the center of R136, the central condensation of stars of the large NGC 2070 open cluster in the Tarantula Nebula. It lies at a distance of about 50 kiloparsecs (163,000 light-years) in the Large Magellanic Cloud. It has the highest mass and luminosity of any known star, at 265 M☉ and 8.7 million L☉, and also one of the hottest at over 50,000 K.
