Asteroids
A nonprofit group is looking to give Earth early warning before dangerous asteroids from outer space come near the atmosphere.
Scientists are still puzzled about the mysterious nature of the centaurs or the sub-planetary bodies that are orbiting the Sun between planets Jupiter and Neptune.
Interested in protecting the Earth from an asteroid-doomsday scenario? If so, NASA has just the project for you: find all potential asteroid threats to the human population, and come up with a way to deal with it.
Everyone's been talking about asteroid 1998 QE2 recently as it flies by our planet, but the 1.7-mile giant has a little friend that was only recently discovered by NASA. Turns out that 1998 QE2 has a traveling companion: a little moon of its own.
An asteroid about nine times the length of the Queen Elizabeth 2 will "sail" by earth this Friday. The asteroid is called 1998 QE2, though it isn't named after the cruise ship, and will safely pass by at about 3.6 million miles, or 15 times the distance between our planet and the moon.
The asteroid that exploded near the Russian city of Chelyabinsk in February really hammered home the need for us to be prepared for the possibility of a more disastrous collision.
NASA and other space experts took to the House Committee on Science, Space, and Technology stage recently, and their remarks about possible asteroid doomsday scenarios are a double-edged sword. On one hand, most are confident that no asteroid will strike the Earth in the next century. On the other, it's going to take a lot of money to prevent - something that seems out of reach thanks to the recent budget cuts.
The Canadian Space Agency is sending a satellite to space later this month to track and monitor the cosmos for space rocks similar to the asteroid that zoomed pass Earth last weekend.
As our planet's natural resources dwindle, people are beginning to look for creative ways to harvest the necessary ingredients to fuel mankind's progress. Space entrepreneurial company Deep Space Industries is now proposing to send out a fleet of miniature satellites as early as 2015 to scope out potential asteroids for mining.
NASA scientists announced on Thursday that new observations of the asteroid dismiss ideas that the giant space rock will impact Earth during its 2036 flyby.
The potentially-dangerous asteroid Apophis is currently passing by Earth, allowing scientists to study it further.
