Big Bubble

A closeup of the star cluster NGC 1929 shows what astronomers call a superbubble—a huge hole about 325 by 250 light-years across—being blown in a star-forming nebula.

The bubble, seen in this newly released shot from the European Southern Observatory, sits in the Large Magellanic Cloud, a small companion galaxy of our Milky Way. The bubble is being carved as radiation from massive, young stars and shockwaves from their explosive deaths push on the nebula's gas and dust.
