The Local Bubble

Where 'local' means 1000 light years or so.

We've known for decades that our Sun sits near the center of a vast expanding bubble in space, a growing cavity carved out of ambient gas in the Milky Way. But a remarkable new study has come out showing that nearly all the nearby gas clouds that are currently forming stars sit on the thin edge of that bubble — strongly implying that the expansion of the bubble itself triggered that star birth.

What created the bubble? More than a dozen supernovae, massive stars that exploded just a few million years after their birth, 14 or so million years ago. The Sun coincidentally is near the center of the bubble, having happened to enter it 5 million years ago as it orbits the center of the galaxy.

This was a fascinating article that makes me wonder if this is yet another protective shield around the earth at just the right time, another seeming 'coincidence'

So this is what our neighbourhood looks like in space. It’s so amazing that this can be known and mapped.
