Theory, observation, and the strange truth about colliding stellar winds

Colliding stellar winds release enormous amounts of energy

Stellar winds thrown out by massive stars behave in surprising ways, according to observations made with the European Space Agency's XMM-Newton observatory. The colliding winds of large stars actually become brighter, and emit more X-rays, as the matter emitted after a stellar event subsides – contrary to expectations. In its search for a reason, the team found answers in a 2014 study, theoretical at the time of writing. Chalk one up for science, then.
