Weekly Roundup | Science and Space: Top 10 stories of the week of Sept 22 - 29th, 2017

"Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive...
