( Reuters) – NASA called on backyard astronomers and other citizen-scientists on Tuesday to help track asteroids that could create havoc on Earth.

The U.S. space agency has already identified 95 percent of the potentially planet-killing NEOs – near Earth objects – with a diameter of .62 miles or more, a size comparable to the space rock many scientists believe wiped out the dinosaurs some 65 million years ago.

Now NASA wants to work with individuals, government agencies, international partners and academia to “find all asteroid threats to human populations and know what to do about them.” Between 50 and 100 amateur astronomers are doing what is called light-curve analysis on space rocks, making repeated images of the astronomical bodies to help determine their characteristics, said Jason Kessler, program executive for what NASA calls Astroid Grand Challenge.

“We’re certainly going to need more help with that as our detection rate goes up,” Kessler said by telephone. He acknowledged that what NASA aims to do, at least in part, is to crowd-source asteroid detection.

Even smaller space rocks can be dangerous, whether or not they hit the Earth. In February, a meteorite about 19 yards in diameter exploded over central Russia, shattering windows, damaging buildings and injuring 1,200 people.

Earlier this month, an asteroid the size of a small truck zoomed past the Earth four times closer than the moon, crossing within about 65,000 miles over the Southern Ocean south of Tasmania, Australia.

Astrophysics needs your help

The latest installment of galaxy zoo is ready you to take part.

For anyone of you thinking ‘Galaxy zoo? What?’ you should check out the project. It collates hundred if thousands of images from both the Hubble space telescope and the SLOAN survey (based 2 hours east of NMSU ). It provided people limited training and sets you free to stay the data and do your own classification. It is the new sexy link from telescopes to the general public. Have a go, let me know what you think.
