Large asteroid zipping past Earth towing moon
Published: Sun May 31, 2013- 5:06AM on CNN
An asteroid is whizzing past Earth on Friday – and it’s traveling with its own moon in tow.
1998 QE2, as NASA has named it, will not come anywhere near enough to collide with our world. The closest it will come is about 3.6 million miles away – that’s over 15 times the distance to our moon. It will reach that point just before 5 p.m. ET.
But it’s giving astronomers the “best look at this asteroid ever,” NASA said.
The discovery of its moon — which makes it what scientists call a binary asteroid — surprised the astronomers, said NASA radar scientist Marina Brozovic, who helped take the images at Deep Space Network antenna at Goldstone, California.

3 new planets could host life
Published: Sun April 21, 2013- 8:48AM on CNN
NASA’s Kepler satellite, which is keeping an eye on more than 150,000 stars in hopes of identifying Earth-like planets, found the trio. Two of the planets — Kepler-62e and Kepler-62f — are described in a study released Thursday in the journal Sci-ence. They are part of a five-planet system in which the candidates for life are the farthest from the host star. Their host star — which corresponds to Earth’s sun, but is smaller and cooler — takes the name Kepler-62. The star’s planets are designated by letters after the star’s name. The star’s planets are designated by letters after the star’s name.

Space station detector gives first clues to ‘dark matter’
Published: Fri April 5, 2013- 6:48AM on CNN
The scientists are studying flux in cosmic rays, the charged high-energy particles that permeate space, for evidence of the invisible dark matter particles colliding with each other, leading to what is termed “annihilation.”
A result of this would be a higher presence of the charged particles known as positrons, the antimatter counterpart of electrons.
