NASA's New 'Intruder Alert' System Spots An Incoming Asteroid
A space rock zips by earth Sunday night. Astronomers know it doesn't pose a threat, in part thanks to a new automated warning program called Scout.
A new 9th planet for the solar system?
Observations of the orbits of six small objects have led researchers to propose a very large 9th planet--100s of astronomical units (AU) away from the sun. F...
Earth's Atmospheric Oxygen Levels Continue Long Slide
Atmospheric oxygen levels have declined over the past 1 million years, although not nearly enough to trigger any major problems for life on Earth, a new study finds.
