The ESA's XMM-Newton observatory captures a huge X-ray emitting bubble in nearby Canis Major. Some 5,000 light years away, hovering in the constellation Canis Major, this massive 60-light-years-across bubble is lurking. Known as a Wolf-Rayet bubble (and thought by some to resembe a wolf- or dog-like head), it's a type of cosmic structure created by huge stars that generate equally colossal stellar winds. When imaged in X-ray, it gives us the shifting blues, greens, yellows, and reds seen above. ...
