Our solar system is actually a wild frontier, teeming with different, diverse places: planets and moons, millions of objects of ice and rock.
When I tell people I'm a space scientist studying asteroids, they sometimes assume I'm a super-smart math whiz. The kind of person who skipped a bunch of grades and went to college when they were sixteen. Although I am good at math, school was difficult for me, and I didn't get straight A's.
It has only been within my lifetime that asteroids have been considered a credible threat to our planet. And since then, there's been a focused effort underway to discover and catalog these objects. I am lucky enough to be part of this effort. I'm part of a team of scientists that use NASA's NEOWISE telescope.
I think the public perception about asteroids is that they're kind of metaphors for acts of God, the fact that we have no control over the universe. They're always seen as these uncontrollable events. But when you look at the science, they're actually the exact opposite.
An asteroid impact in the worst case scenario is a terrifying thing. It seems very uncontrollable: in popular culture, it's often a metaphor for human powerlessness over the world.
An asteroid impact is a preventable natural disaster. It's in part preventable because we have the technology, and it's in part preventable because it's predictable.
