Astrophysicist Neil deGrasse Tyson, a popular host of PBS’ Nova, says the humans must do something about the approaching asteroid Apophis. “I don’t want to be the laughing stock of the galaxy and go extinct as a species because we didn’t do something about it,” he said at the 25th National Space Symposium in Colorado Springs this week.

Morrow Public Outreach Award at the confab.
