Run Away Now
Science Made Cool warns readers about the approaching killer cloud that could sterilize our corner of the galaxy in as little as 20 million years:
What’s likely to happen when it does arrive? A wave of new star formation — lots of new, bright, massive stars forming and then blowing themselves to smithereens in supernova explosions only a few million years later. The whole region of the Milky Way Galaxy is likely to become uninhabitable as the supernovae flood it with energetic radiation.
Really, there’s nothing to do but move to the other side of the Galaxy and wait for the storm to pass. That may take some time — the Milky Way is about 100,000 light-years across, and the central region is probably uninhabitable.
