Astronomers reveal nearby stars that are among the oldest in our galaxy
Astronomers have discovered some of the oldest stars in our Milky Way galaxy by determining their locations and velocities.

Previous evidence of water on Mars now identified as grainflows
Dark features previously proposed as evidence for significant liquid water flowing on Mars have now been identified as granular flows, where sand and dust move rather than liquid water, according to a new article. These findings indicate that present-day Mars may not have a significant volume of liquid water. The water-restricted conditions that exist on Mars would make it difficult for Earth-like life to exist near the surface.

First interstellar asteroid is like nothing seen before
For the first time ever astronomers have studied an asteroid that has entered the Solar System from interstellar space. Observations from ESO's Very Large Telescope in Chile and other observatories around the world show that this unique object was traveling through space for millions of years before its chance encounter with our star system. It appears to be a dark, reddish, highly-elongated rocky or high-metal-content object.

Space dust may transport life between worlds, research suggests
Life on Earth might have originated from tiny organisms brought to our planet in streams of fast-moving space dust, according to a new study.

Don't Let an Old Myth Prevent Your Child from Seeing the Solar Eclipse
Joe Rao's second book, "Looking Up!: The Science of Stargazing," debunks an old myth about solar eclipses and teaches kids (and parents) how to safely experience this amazing event.

Hubble gazes into a black hole of puzzling lightness
The beautiful spiral galaxy visible in the center of the image is known as RX J1140.1+0307, a galaxy in the Virgo constellation imaged by the NASA/ESA Hubble Space Telescope, and it presents an interesting puzzle. At first glance, this galaxy appears to be a normal spiral galaxy, much like the Milky Way, but first appearances can be deceptive!

French, US astronauts install batteries outside space station (Update)

Video: Huygens' descent to Titan
On December 25, 2004, the piggybacking Huygens probe was released from the 'mothership' Cassini spacecraft and it arrived at Titan on January 14, 2005. The probe began transmitting data to Cassini four minutes into its descent through Titan's murky atmosphere, snapping photos and taking data all the while. Then it touched down, the first time a probe had landed on an extraterrestrial world in the outer Solar System.

How old is our moon?
Most scientists agree that the Earth has pretty much always had its moon. Details of the moon's composition (in particular the "isotopic mixture" of heavier and lighter versions of various elements) are too similar to the Earth's for it to have been captured from somewhere remote. However, some compositional details differ enough to rule out the idea that the moon is simply a chunk of the Earth that broke loose.
