Moon from Space: Aboard the International Space Station, astronaut Reid Wiseman snapped this image and posted it to Twitter. He wrote, "I missed the #supermoon but it still looked great setting today!" Image Credit: NASA

Tall Boulder Rolls Down Martian Hill, Lands Upright: The track left by an oblong boulder as it tumbled down a slope on Mars runs from upper left to right center of this image. The boulder came to rest in an upright attitude at the downhill end of the track. The HiRISE camera on our Mars Reconnaissance Orbiter recorded this view on July 14, 2014.

TONIGHT: The annual Perseid meteor shower peaks! Check the map below for your city/state's visibility. Best Visibility = up to 30-40 meteors/hour; Visible, Low Rates = up to 10 meteors/hour; and Visible, Very Low Rates = less than five meteors/hour. You may see Perseids any time after dark, but peak viewing will be Aug. 13, 3-4 a.m. local time. This is true for all locations in the world.

Our NuSTAR Mission Sees Rare Blurring of Black Hole Light: The regions around supermassive black holes shine brightly in X-rays. Some of this radiation comes from a surrounding disk, and most comes from the corona, pictured here as the white light at the base of a jet. This is one possible configuration for a corona -- its actual shape is unclear.

Astronaut Reid Wiseman installs Capillary Channel Flow (CCF) experiment hardware in the Microgravity Science Glovebox located in the Destiny laboratory of the International Space Station. CCF is a versatile experiment for studying a critical variety of inertial-capillary dominated flows key to spacecraft systems that cannot be studied on the ground.
Capillary flow is the natural wicking of fluid between narrow channels in the opposite direction of gravity. Tree roots are one example of a capillary system, drawing water up from the soil. By increasing understanding of capillary flow in the absence of gravity, the CCF experiment helps scientists find new ways to move liquids in space. Capillary systems do not require pumps or moving parts, which reduces their cost, weight and complexity.

Astronaut Reid Wiseman aboard the International Space station tweeted this image and wrote, "Florida and Cuba under the #supermoon this past Saturday morning." The six-member Expedition 40 crew is conducting its normal suite of international science and maintenance while waiting for Europe's Automated Transfer Vehicle-5 (ATV-5) to dock Tuesday at 9:30 a.m. EDT.

It's a supermoon! A perigree full moon or "supermoon" is seen, Sunday, Aug. 10, 2014, in Washington. A supermoon occurs when the moon's orbit is closest (perigee) to Earth at the same time it is full.

Tonight's full moon will appear larger and brighter than any other full moon this year. This #supermoon will be visible everywhere in the world. August's full moon rises when the natural satellite is at perigee - the closest point to Earth in its orbit.

Our NEOWISE mission detected comet C/2013 A1 Siding Spring on July 28, 2014, less than three months before this comet's close flyby of Mars on Oct. 19. NEOWISE took multiple images of the comet, combined here so that the comet is seen in four different positions relative to the background stars. The image also includes, near the upper right corner, a view of radio galaxy Fornax A (NGC1316). The observations help constrain estimates of dust and gas production as this comet from the outer solar system approaches Mars.
NGC1316 has an active nucleus, as evidenced by a radio jet and a compact nuclear gas disk. It is thought to be the remnant of a merger between a large elliptical galaxy and a smaller spiral galaxy about 100 million years ago.

Aboard the International Space Station, Expedition 40 crew member Reid Wiseman posted this image and wrote, "Passing over India just now. Undoctored...unedited...unbelievable." Over the weekend, the station's astronauts and cosmonauts will take care of weekly housekeeping chores as they wipe down surfaces and vacuum dust. They also will continue their daily 2.5-hour workouts to stay fit and to prevent the loss of muscle mass and bone density that occurs in microgravity.

The International Space Station's Expedition 40 crew closed out the work-week with preparations for the arrival of one space freighter and the departure of another, upgrades to the station's robotic crew member and a checkout of a pair of spacesuits for an upcoming spacewalk.
One of the crew members aboard the space station, from an altitude of 221 nautical miles, photographed this image of Typhoon Halong at 08:02:41 GMT on Aug. 7, 2014.

A globular cluster's age revisited: Globular clusters are big balls of old stars that orbit around their host galaxy. It has long been believed that all the stars within a globular cluster form at the about same time, a property which can be used to determine the cluster's age. For more massive globulars however, detailed observations have shown that this is not entirely true - there is evidence that they instead consist of multiple populations of stars born at different times. One of the driving forces behind this behaviour is thought to be gravity: more massive globulars manage to grab more gas and dust, which can then be transformed into new stars.
IC 4499 is a somewhat special case. Its mass lies somewhere between low-mass globulars, which show a single generation build-up, and the more complex and massive globulars which can contain more than one generation of stars. By studying objects like IC 4499 astronomers can therefore explore how mass affects a cluster's contents.

Fishing LDSD Out of the Water: Divers retrieve the test vehicle for our Low-Density Supersonic Decelerator off the coast of the U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii. On June 28, 2014, the vehicle was lifted to near-space with the help of a balloon and rocket in order to test new Mars landing technologies. The divers, from the U.S. Navy's Explosive Ordnance Disposal team, retrieved the vehicle hours after the successful test.

The Sun sported a very long filament (over 30 times the size of Earth) that angled diagonally across its surface for over a week (July 31 - Aug. 6, 2014). Filaments are clouds of cooler gas suspended above the Sun's surface by magnetic forces. They are notoriously unstable and often break apart in just hours or days. So far, this one has held together as it rotated along with the Sun for over a week. The images were taken in the 193 Angstrom wavelength of extreme ultraviolet light and were tinted red instead of its usual brown hue.

In his newest film released recently, Dwayne Johnson is Hercules—the demigod who fights against evil and helps to end a civil war. But back in 2011, after playing the American astronaut Captain Chuck Baker in Planet 51, The Rock was touting the benefits of NASA technology for people here on earth.
