Briefly glowing brighter than the sun itself, the meteor exploded 14 miles (22.5 kilometers) above the ground with 30 times more energy than the bomb that destroyed Hiroshima. The Chelyabinsk meteor is thought to be the biggest natural space object to enter Earth's atmosphere in more than 100 years. Yet no observatory on Earth saw it coming. Arriving from the direction of the sun, the rock remained hidden in our biggest blind spot until it was too late. Events like these are, fortunately, uncommon. To date, astronomers have mapped the orbits of more than 33,000 near-Earth asteroids and found that none pose a risk of hitting our planet for at least the next century. But you can't calculate the risk of an asteroid you can't see — so how can two upcoming space telescopes help us figure out what's there, and what the true risk is?
