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.
