From NPR -- Take a close look at the image below showing a newly formed impact crater on Mars: The blue streaks of material, known as ejecta, radiate 9 miles from the 100-foot crater, according to NASA. The picture was taken from orbit by the on Nov. 19. The same area was imaged by the MRO's Context Camera in July 2010 and again in May 2012 — with no crater in the first and a telltale surface scar in the second.
From NASA -- More than 400 years after its discovery by astronomer Galileo Galilei, the largest moon in the solar system – Jupiter's moon Ganymede – has finally claimed a spot on the map.
ScienceCasts, NASA’s new video series, offers middle and high school educators and the public a fast and fun way to learn about scientific discoveries and facts about Earth, the solar system, and beyond. The videos were produced by an astrophysicist and a team of agency narrators and videographers. The format is designed to increase understanding of the world of science through simple, clear presentations. The videos are available in YouTube, Vimeo, and available for download.
NASA's Curiosity rover is providing vital insight about Mars' past and current environments that will aid plans for future robotic and human missions. In a little more than a year on the Red Planet, the mobile Mars Science Laboratory has determined the age of a Martian rock, found evidence the planet could have sustained microbial life, taken the first readings of radiation on the surface, and shown how natural erosion could reveal the building blocks of life.

There is much excitement in the space science community, with the successful landing of the Chang’E 3 spacecraft, carrying the Yutu (Jade Rabbit) surface rover on December 14. These websites (in English) contain images, video, and some of the earliest data from the rover.
From NSF -- Astronomers have collectively puzzled over two working theories for a conundrum involving the sun that have been discussed in Astronomy 101 classes for decades: Why is the sun's corona (the atmosphere beyond the sun) so hot? The sun's core is a searing 15 million degrees Kelvin, but by the time that heat reaches the sun's surface, it cools off to a mere 6,000 degrees, only to again heat up to more than a million degrees in the corona.
From NASA/JPL (October 17, 2013) - Newly discovered asteroid 2013 TV135 made a close approach to Earth on Sept. 16, when it came within about 4.2 million miles (6.7 million kilometers). The asteroid is initially estimated to be about 1,300 feet (400 meters) in size and its orbit carries it as far out as about three quarters of the distance to Jupiter's orbit and as close to the sun as Earth's orbit. It was discovered on Oct.
As ground-based gravitational-wave detectors get ready to score their first direct measurement of the ripples of spacetime, thoughts turn to space-based detectors that could see all the way back to the big bang.
