NASA scientists will be tracking asteroid 2005 YU55 with antennas of the agency’s Deep Space Network at Goldstone, Calif., as the space rock safely flies past Earth slightly closer than the moon’s orbit on Nov. 8. Scientists are treating the flyby of the 1,300-foot-wide (400-meter) asteroid as a science target of opportunity – allowing instruments on “spacecraft Earth” to scan … Read the rest of this article

Asteroid Family Believed Responsible for Dinosaur Extinction May Not Be Responsible After All
September 24, 2011
Observations from NASA’s Wide-field Infrared Survey Explorer (WISE) mission indicate the family of asteroids some believed was responsible for the demise of the dinosaurs is not likely the culprit, keeping the case open on one of Earth’s greatest mysteries.

Dawn Spacecraft Images Vesta’s Striking Features
September 20, 2011
A new video from NASA’s Dawn spacecraft takes us on a flyover journey above the surface of the giant asteroid Vesta.
This image obtained by the framing camera on NASA’s Dawn spacecraft shows the south pole of the giant asteroid Vesta. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA
The data obtained by Dawn’s framing camera, used to produce the visualizations, will help scientists determine … Read the rest of this article
After a journey of almost three years, NASA’s Mars Exploration Rover Opportunity has reached the Red Planet’s Endeavour crater to study rocks never seen before.

A portion of the west rim of Endeavour crater sweeps southward in this color view from NASA’s Mars Exploration Rover Opportunity. This crater — with a diameter of about 14 miles (22 kilometers) — is …
Comet Elenin Will Be in the Sky in October
August 6, 2011
Comet Elenin is coming to the inner-solar system this fall/autumn. Comet Elenin (also known by its astronomical name C/2010 X1), was first detected on Dec. 10, 2010 by Leonid Elenin, an observer in Lyubertsy, Russia, who made the discovery “remotely” using the ISON-NM observatory near Mayhill, New Mexico. At the time of the discovery, the comet was about 647 million … Read the rest of this article
Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The water, equivalent to 140 trillion times all the water in the world’s ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away.

NASA’s Dawn spacecraft will begin a prolonged encounter with the asteroid Vesta today (July 15), making the mission the first to enter orbit around a main-belt asteroid.
The main asteroid belt lies between the orbits of Mars and Jupiter. Dawn will study Vesta for one year, and observations will help scientists understand the earliest chapter of our solar system’s history.… Read the rest of this article
A five-year survey of 200,000 galaxies, stretching back seven billion years in cosmic time, has led to one of the best independent confirmations that dark energy is driving our universe apart at accelerating speeds.
The survey used data from NASA’s space-based Galaxy Evolution Explorer and the Anglo-Australian Telescope on Siding Spring Mountain in Australia.
