Blowing Bubbles around our Galaxy!
The star-making factory is found inside the red ring. This is a cloud of gas and dust, which is called a ‘Super-bubble’. The Super-bubble’s ring shape is due to a combination of destructive events. Fierce winds from massive stars and the explosions of dying stars have hollowed-out the centre of the cloud, leaving just a ring of gas and dust.
