A first-of-its-kind space rock filled with pristine material from the formation of the Earth itself has returned to the inner solar system, after billions of years in the cosmic boondocks. And it could help us piece together our planet’s origin story.
If you haven't yet seen the comet PANSTARRS' current pass, take a look at Dan Finnerty's time-lapse video. He captured the comet's flight toward the horizon from Altadena, California, in tandem with the setting moon.
Yesterday, the comet 2011 L4 (called PANSTARRS after the Panoramic Survey Telescope and Rapid Response System) became visible in the Northern Hemisphere for the first time, meaning some of us north of the equator will have a chance to view a comet before ISON's passage in the fall. But you'll need the right conditions…
First step in preventing Armageddon: Spot the asteroid before it obliterates all life on earth. The PS1 Telescope sits atop a Hawaiian mountain with a 1.4-gigapixel digital camera to ensure we get the Ben Affleck-approved ending, not Deep Impact.
The Pan-STARRS, a new 1.4 gigapixel telescope built to spot asteroids, has found a potentially dangerous asteroid headed for Earth. Luckily, we don't have to worry just yet. It won't hit us 'til 2098.
A new telescope, equipped with a 1.8 billion pixel camera, has discovered its first potentially dangerous asteroid. The rock is a lot smaller than any other asteroid we've detected before, and that's great news for our still-developing asteroid defense system.
