Or: Emily reads you the table of contents of Icarus.
That's a bit of an overdramatic title, but it's true that the most efficient way for us to reduce the risk we face from asteroids that have a very small chance of hitting Earth in the future is to determine their orbits more precisely.
Are you a serious amateur astronomer who enjoys the challenge of following up on the discoveries of faint near-Earth objects?
This week Bruce Betts is attending a U.N. meeting in Austria, in particular the parts focused on international considerations of the near-Earth object threat.
It was January of 2004 when the elegant curve of the Vichada first caught the attention of geologist Max Rocca of Buenos Aires. Could the course of the river have been shaped by the circular outlines of an impact crater? Rocca decided to find out.
In less than 24 hours, a newly discovered asteroid known as 2010 AL30 will be zipping past Earth at an altitude of approximately a third the Earth-Moon distance. There's no chance it'll hit us, but it's generating a lot of excitement in the community of amateur and professional near-Earth asteroid observers.
Could a space rock hit Earth and cause widespread devastation? What could we do if we found an asteroid or comet on a collision course with Earth?
I was debating whether to write anything about a reported fireball that streaked across the sky in the Netherlands at roughly 19:00 local time (17:00 UTC) yesterday, October 13, but seeing this image ended my internal debate.
Based on analyses of previously unstudied telescopic data, NASA scientists have released new predictions for the path of the 300-meter-diameter asteroid Apophis.
Astronomers have revised the Torino scale, the color-coded advisory system to assess the threat of asteroids and other near-Earth objects (NEOs) to make it easier for the public to understand.
This morning, asteroid 4179 Toutatis was so close to Earth that simultaneous observations from two telescopes in the same country could show parallax that is obvious even to the least experienced observer. The two telescopes belong to The European Southern Observatory and are located at La Silla and Paranal in Chile
On Wednesday, September 29, Earth will dodge a cannonball: the Near-Earth Asteroid known as 4179 Toutatis will buzz by at a distance only four times the distance from the Earth to the Moon -- about one and a half million kilometers, or about a million miles. But, as the wisdom goes,
