- Microbes and Molecules Get a Space-stress Test
- Astrobiologists searching for life beyond Earth need to know how well life and its building blocks fare in space. To find out, NASA will monitor a miniature aamp;quot;crewaamp;quot; of organic molecules and microbes orbiting Earth for 6 months.
- Lunar Impact Uncovered More Than Just Moon Water
- Nearly a year after announcing the discovery of water molecules on the moon, scientists say thereaamp;#39;s more than just water hiding in cold lunar craters.
- NASA Spacecraft Hurtles Toward… tive Comet Hartley 2
- NASAaamp;#39;s Deep Impact/EPOXI spacecraft is hurtling toward Comet Hartley 2 for a breathtaking flyby on Nov. 4th. Mission scientists say all systems are go for a close encounter with one of the smallest yet most active comets theyaamp;#39;ve seen.
- Hubble Observes Aftermath of Possible… oid Collision
- NASAaamp;#39;s Hubble Space Telescope has captured rare images of a suspected asteroid collision. The snapshots show a bizarre X-shaped object at the head of a comet-like trail of material. Their findings will be published in the Oct. 14th issue of Nature.
- The Year of the Solar System
- Planetary exploration is shifting into high gear with an unprecedented tripling of flybys, orbital insertions and launches to destinations around the solar system. To commemorate the increase, NASA has declared the year ahead aamp;quot;The Year of the Solar System.aamp;quot;
- Watch out for the Super Harvest Moon
- For the first time in almost 20 years, northern autumn is beginning on the night of a full Moon. The coincidence sets the stage for a aamp;quot;Super Harvest Moonaamp;quot; and a must-see sky show to mark the change of seasons.
- Solar Storms can Change Directions,… ing Forecasters
- Researchers using data from NASAaamp;#39;s STEREO spacecraft have found that solar storms donaamp;#39;t always travel in a straight line. This adds a surprising new twist to the science of space weather forecasting.
- Closest Encounter with Jupiter until 2022
- Jupiter and Earth are converging for their closest encounter in more than a decade. Only the Moon itself is outshining the giant planet in the midnight sky, and the view through a telescope is dynamite.
- This Planet Smells Funny
- An alien world in the constellation Leo is breaking the rules of giant-planet chemistry, prompting researchers to re-think the make-up of exoplanet atmospheres.
