NASA spots a 'potentially hazardous' new asteroid

Say hello to 2013 YP139 — a newly discovered 0.4 mile (650 meter) wide asteroid spotted by NASA's recently re-started NEOWISE spacecraft. Preliminary calculations show it'll come within 300,000 miles from Earth — thus qualifying it as a potential headache. » 1/08/14 2:20pm 1/08/14 2:20pm

The orbits of all potentially hazardous asteroids in one map

NASA has put together an image showing the orbits of all known Potentially Hazardous Asteroids (PHAs) currently threatening Earth. That's 1,400 in total — making this map uncomfortably busy. » 8/12/13 2:54pm 8/12/13 2:54pm

The boulder-sized fireball, which got as bright as the full moon, was seen all the way from South Carolina to Maine. » 3/25/13 1:03pm 3/25/13 1:03pm

How serious does an asteroid threat have to be before we take action?

Bureaucratic molasses gums up asteroid apocalypse prevention

A 2005 congressional mandate requires NASA to record 90% of the 20,000+ near Earth objects (NEOs) sized 140+ meters in diameter. NASA has until 2020 to catalog them but lacks time and funding. Ah, the politics of doomsday prevention. » 9/13/10 2:50pm 9/13/10 2:50pm
