A solar prominence began to bow out and the broke apart in a graceful, floating style in a little less than four hours (Mar. 16, 2013). The sequence was captured in extreme ultraviolet light. A large cloud of the particles appeared to hover further out above the surface before it faded away. Credit: Solar Dynamics Observatory/NASA


Opportunity Moves Into Place for Quiet Period of Operations - sols 3255-3260, Mar. 21, 2013-Mar. 26, 2013: This location, called 'Big Nickel,' is the last in-situ (contact) target before the rover departs from Cape York, once solar conjunction is concluded.

One of the Expedition 35 crew members aboard the Earth-orbiting International Space Station exposed this 400 millimeter night image of the greater New York City metropolitan area on March 23. For orientation purposes, note that Manhattan runs horizontal through the frame from left to the midpoint. Central Park is just a little to the left of frame center.

One of the Expedition 35 crew members aboard the Earth-orbiting International Space Station took this photo which was part of a series documenting the launch of the "other half" of the Expedition 35 crew. The Soyuz TMA-08M rocket launched from the Baikonur Cosmodrome in Kazakhstan on March 29, 2013 (Kazakh time) carrying Expedition 35 Soyuz Commander Pavel Vinogradov, NASA Flight Engineer Chris Cassidy and Russian Flight Engineer Alexander Misurkin to the International Space Station. Their Soyuz rocket launched at 2:43 a.m., March 29, local time, while it was still March 28 in GMT and USA time zones. ISS035-E-010313 (28 March 2013) - high res (2.7 M) low res (49 K)

"Citizen science, in which volunteers work with professional scientists to conduct research, is expanding due to large online datasets. To plan projects, it is important to understand volunteers' motivations for participating. This paper analyzes results from an online survey of nearly 11,000 volunteers in Galaxy Zoo, an astronomy citizen science project. Results show that volunteers' primary motivation is a desire to contribute to scientific research. We encourage other citizen science projects to study the motivations of their volunteers, to see whether and how these results may be generalized to inform the field of citizen science." More


NASA is about to get a chance to try something totally new: instead of just visting or landing on things in space, it is going to go grab one of those things - something that is rather huge - and bring it back to Earth. Details will be formally announced on 10 April 2013 when the new budget is rolled out.


Three new crew members are on an unprecedented fast track to the International Space Station, going from the launch pad to the orbiting complex in just six hours.


The discovery of box-like geologic structures on Mount Sharp centered in Curiosity's Gale crater landing site, is raising interest for rover exploration as potentially habitable for past life on Mars.


The International Astronomical Union (IAU) - the arbiter of planetary and satellite nomenclature since its inception in 1919 - recently approved a proposal from the MESSENGER Science Team to assign names to nine impact craters on Mercury. In keeping with the established naming theme for craters on Mercury, all of the newly designated features are named after famous deceased artists, musicians, or authors or other contributors to the humanities.

A new analysis of data from NASA's Cassini spacecraft suggests that Saturn's moons and rings are gently worn vintage goods from around the time of our solar system's birth.


The first firm details of the 15 February asteroid impact in Russia, the largest in more than a century, are becoming clear. ESA is carefully assessing the information as crucial input for developing the Agency's asteroid-hunting effort.


In this new view of a vast star-forming cloud called W3, ESA's Herschel space observatory tells the story of how massive stars are born.

In this new view of a vast star-forming cloud called W3, ESA's Herschel space observatory tells the story of how massive stars are born.

W3 is a giant molecular cloud containing an enormous stellar nursery, some 6200 light-years away in the Perseus Arm, one of our Milky Way Galaxy's main spiral arms.

The UK Space Agency is pleased to announce new chairpersons for two of its advisory committees: the Science Programme Advisory Committee (SPAC) and Space Exploration Advisory Committee (SEAC).

One of the Expedition 34 crew members aboard the International Space Station recorded this night image of the British Isles. The view is to the north with Dublin, Ireland left of center. London appears as the bright cluster of lights centered in the lower right quadrant. The green appearance along the horizon is the Aurora Borealis or Northern Lights.

Until now, supernovas came in two main "flavors." A core-collapse supernova is the explosion of a star about 10 to 100 times as massive as our Sun, while a Type Ia supernova is the complete disruption of a tiny white dwarf. Today, astronomers are reporting their discovery of a new kind of supernova called Type Iax. This new class is fainter and less energetic than Type Ia. Although both varieties come from exploding white dwarfs, Type Iax supernovas may not completely destroy the white dwarf.

The Soyuz rocket is rolled out to the launch pad by train on Tuesday, March 26, 2013, at the Baikonur Cosmodrome in Kazakhstan. Launch of the Soyuz rocket is scheduled for March 29 and will send Expedition 35 Soyuz Commander Pavel Vinogradov, and Flight Engineers Chris Cassidy of NASA and Alexander Misurkin of Russia on a five-and-a-half-month mission aboard the International Space Station.

NASA's Mars rover Curiosity has resumed science investigations after recovery from a computer glitch that prompted the engineers to switch the rover to a redundant main computer on Feb. 28. The rover has been monitoring the weather since March 21 and delivered a new portion of powdered-rock sample for laboratory analysis on March 23, among other activities.

"We are back to full science operations," said Curiosity Deputy Project Manager Jim Erickson of NASA's Jet Propulsion Laboratory, Pasadena, Calif.
