1,000-LIGHT-YEAR-WIDE BUBBLE SURROUNDING EARTH IS SOURCE OF ALL NEARBY, YOUNG STARS

Astronomers at the Center for Astrophysics | Harvard & Smithsonian and the Space Telescope Science Institute have reconstructed the evolutionary history of our galactic neighborhood, showing how a chain of events beginning 14 million years ago led to the creation of a vast bubble that's responsible for the formation of all nearby, young stars.

We used to think the moon was made out of swiss cheese. Now we find that space itself is... :P

An enormous,1,000-light-year-wide "superbubble" surrounds our planet. Now, astronomers have made the first ever 3D map of its magnetic field.

Close.

The main problem is that the local bubble is a, well, bubble. Inside the bubble the density of interstellar hydrogen is a pathetic one-tenth compared to the rest of the galaxy.

The rest of the problem is the local bubble is about four hundred freaking light years in diameter, and the solar system is close to the center.
