Saturn's Odd Pockmarked MoonNASA's Cassini spacecraft has captured new photos of Saturn's ugly-duckling moon Hyperion that show its cratered surface up close. Closeup view of Hyperion taken by NASA's Cassini spacecraft on Aug. 25, 2011.
The pictures come from Cassini's Aug. 25 flyby of the Saturn moon Hyperion. The pass, the spacecraft's second closest encounter with the moon, brought Cassini within about 15,500 miles (25,000 kilometers) of Hyperion’s surface. [Full Story]

Hubble Videos Show Baby Stars & Violent JetsNew details about the violent birth of new stars are revealed in a series of movies compiled from 14 years' worth of Hubble Space Telescope observations.
The videos, released Aug. 31, stitch together pictures of nascent stars at various periods to present continuous-motion views of how stars are born. They reveal, in particular, how high-speed jets from baby stars can spew out matter in two beams that fizzle out over time. [Full Story]

'Exotic Galaxy' With Black Hole Heart Wows AstronomersA strange, newfound galaxy may help astronomers figure out how black holes and star formation evolved in the early universe, according to a new study.
The spiral galaxy, dubbed Speca, boasts fast-moving jets of particles rushing from its center, a phenomenon more commonly observed in elliptical galaxies. In fact, Speca is just the second spiral known to have such jets. [Full Story]

Satellite Sees Burning Man Festival From SpaceThe annual Burning Man festival is in full swing in the Nevada desert, and a tiny European satellite has snapped an overhead shot of the eccentric action.
The European Space Agency's Proba-1 microsatellite took a photo of Burning Man on Thursday (Sept. 1) from an altitude of about 373 miles (600 kilometers). The picture shows campers and tents massed for the annual gathering, which attracts 50,000 people to the Black Rock Desert 120 miles (193 km) north of Reno. [Full Story]

Ice Ice BabyThe Mars Express High-Resolution Stereo Camera captured this image on 17 May 2010 (though it was only released recently), showing a part of the northern polar region of Mars at the northern hemisphere summer solstice. At this point in the Martian year all of the carbon dioxide ice has warmed and evaporated into the planet’s atmosphere. Only water ice is left behind, which shows up as bright white areas in this picture. [See the full daily space photos gallery]
