Violent Collision of Stellar Winds Detected

[mickw]

For the first time, astronomers have pinpointed the spot where the intense winds of two massive stars in a binary system violently collide and detected the production of high-energy X-rays there.
The monstrously large Eta Carinae binary contains between 100 and 150 times the mass of the sun and glows more brightly than four million suns together. The so-called hypergiant contains two massive stars, the second of which was not discovered until 2005.
