LOS ANGELES – Worried about Earth-threatening asteroids? 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," but in the language of astronomy that means within 30 million miles. Luckily for us, none poses any threat to Earth anytime soon.
Called WISE for Wide-field Infrared Survey Explorer, the telescope completes its first full scan of the sky on Saturday and then begins another round of imaging.
What's special about WISE is its ability to see through impenetrable veils of dust, picking up the heat glow of objects that are invisible to regular telescopes.
"Most telescopes focus on the hottest and brightest objects in the universe," said Richard Binzel of the Massachusetts Institute of Technology. "WISE is especially sensitive to seeing what's cool and dark, what you could call the stealth objects of the universe."
Mission team members are elated with the discoveries of the $320 million project, which launched in December. By the end of the year, researchers expect to have a cosmic census of millions of newfound objects that should help answer questions about how planets, stars and galaxies form.
