LOS ANGELES (AP) - One of NASA's newest space telescopes has spotted 25,000 never-before-seen asteroids in just six months.
Ninety-five of those are considered "near Earth" - asteroids that come within 30 million miles of Earth's orbit. Luckily, none poses any threat to Earth anytime soon.
The Wide-field Infrared Survey Explorer, or WISE for short, completes its first full scan of the sky tomorrow, and then begins another round of imaging.
What's special about the telescope is its ability to see through impenetrable veils of dust, picking up the heat glow of objects that are invisible to regular telescopes.
WISE also sighted 15 new comets and confirmed the existence of 20 new brown dwarfs, which are bigger than a planet but much smaller than a star.
