160,000 light years from home, the Tarantula nebula (how's that for a Halloweeny name?) is a factory cranking out thousands of stars. Some of these stars are so luminous they have heated the gas to millions of degrees, and this expanding hot gas (in blue) has pushed open bubbles in the cooler gas around them (red).
And if that were happening inside of you, I imagine you'd be screaming in fury as well.
Man, that is one ticked off nebula. I'm glad it's so far away.Image credit: X-ray: NASA/CXC/PSU/L.Townsley et al.; Infrared: NASA/JPL/PSU/L.Townsley et al.
