Iberian Peninsula at Night
One of the International Space Station crew members recorded this early evening photo of the entire Iberian Peninsula (Spain, and Portugal) on July 26, 2014. Part of France can be seen at the top of the image and the Strait of Gibraltar is visible at bottom, with a very small portion of Morocco visible near the lower right corner.

Our Research Shows Giant Asteroids Battered Early Earth: More than four billion years ago the surface of Earth was heavily reprocessed - or melted, mixed, and buried - as a result of giant asteroid impacts. A new terrestrial bombardment model, calibrated using existing lunar and terrestrial data, sheds light on the role asteroid collisions played in the evolution of the uppermost layers of the early Earth during the geologic eon called the "Hadean" (approximately 4 to 4.5 billion years ago). An artistic conception of the early Earth, showing a surface pummeled by large impact, resulting in extrusion of deep seated magma onto the surface. At the same time, distal portion of the surface could have retained liquid water.

First Image of the Moon Taken by a U.S. Spacecraft: Ranger 7 took this image, the first picture of the moon by a U.S. spacecraft, on July 31, 1964 at 13:09 UT (9:09 AM EDT), about 17 minutes before impacting the lunar surface.
The Ranger series of spacecraft were designed solely to take high-quality pictures of the moon and transmit them back to Earth in real time. The images were to be used for scientific study, as well as selecting landing sites for the Apollo moon missions. Ranger 7 was the first of the Ranger series to be entirely successful. It transmitted 4,308 high-quality images over the last 17 minutes of flight, the final image having a resolution of 0.5 meter/pixel. Ranger 7 was launched July 28, 1964 and arrived at the moon on July 31, 1964.

We selected proposals for two new instruments that will observe changes in global vegetation from the International Space Station. The sensors will give scientists new ways to see how forests and ecosystems are affected by changes in climate or land use change.
This image of the Amazon rainforest is from a 2010 global map of the height of the world’s forests based on multiple satellite datasets.

Liftoff! The European Space Agency’s (ESA) fifth and final Automated Transfer Vehicle (ATV-5) launched Tuesday atop an Ariane 5 rocket from Kourou, French Guiana, at 7:47 p.m. EDT. The ATV-5 will take a two week trip to the International Space Station docking to the Zvezda service module on Aug. 12 at 9:43 a.m. with 7 tons of science, food, fuel and supplies.
En route to the station, the Georges Lemaitre will pass 3.9 miles beneath the space station Aug. 8 so European flight controllers can test new rendezvous sensors. Engineers may use the new sensors in the design and manufacture of future European spacecraft. After the “fly-under”, the ATV-5 will pass in front, above and behind the station for the final four days of its rendezvous with Zvezda.

Go get your 3-D glasses, you know, the blue-red ones with the red lens on the left. This stereo view from our Mars Exploration Rover Opportunity will appear three-dimensional. The view combines several images taken by Opportunity's Pancam and was obtained on the rover's 3,644th Martian day (sol) of exploration (April 24, 2014). Part of the rover is visible at bottom, including its rear solar arrays and low-gain antenna - the antenna appears incomplete here due to combining images with different camera pointings.
Each day's drive by Opportunity sets a new record for longest travel on wheels on a world other than Earth.

Geysers on icy Saturn moon! Scientists using mission data from our Cassini spacecraft have identified 101 distinct geysers erupting on Saturn's icy moon Enceladus, suggesting it is possible for liquid water to reach moon's surface from its underground sea.
This view looks across the geyser basin of Saturn's moon Enceladus, along fractures spewing water vapor and ice particles into space.

Caught between the sun and our Solar Dynamics Observatory... the moon. The phenomenon, called a lunar transit, was observed on July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT. This happens approximately twice a year, causing a partial solar eclipse that can only be seen from SDO's point of view. Images of the eclipse show a crisp lunar horizon, because the moon has no atmosphere that would distort light.

Hubble Serves a Slice of Stars
The thin, glowing streak slicing across this image cuts a lonely figure, with only a few foreground stars and galaxies in the distant background for company.
However, this is all a case of perspective; lying out of frame is another nearby spiral. Together, these two galaxies make up a pair, moving through space together and keeping one another company.
The subject of this Hubble image is called NGC 3501, with NGC 3507 as its out-of-frame companion. The two galaxies look very different — another example of the importance of perspective. NGC 3501 appears edge-on, giving it an elongated and very narrow appearance. Its partner, however, looks very different indeed, appearing face-on and giving us a fantastic view of its barred swirling arms.
While similar arms may not be visible in this image of NGC 3501, this galaxy is also a spiral — although it is somewhat different from its companion. While NGC 3507 has bars cutting through its center, NGC 3501 does not. Instead, it's loosely wound spiral arms all originate from its center. The bright gas and stars that make up these arms can be seen here glowing brightly, mottled by the dark dust lanes that trace across the galaxy.

Yesterday, astronaut Reid Wiseman shared this image of Earth showing Italy at night from the International Space Station tweeting "I looked on in awe and was rendered speechless by so much beauty." The Expedition 40 crew has been hard at work 260 miles above us in the floating laboratory. They set a new record for #ISS research completed in a week -- 82 hours -- this past week.

Peering through the layers: This collage of images shows an active region on the Sun taken at almost the same time in extreme ultraviolet light by NASA's Solar Dynamics Observatory on July 24, 2014 at about 17:56 UTC. The layers are arranged clockwise from the upper left by temperature of plasma being imaged. This arrangement also correlates with the distance above the Sun's surface, going from lowest to highest. Different features of the active region appear quite differently in the four images: each one helps to provide scientists with more information about the Sun's processes.

The Sunshield on NASA's James Webb Space Telescope is the largest part of the observatory—five layers of thin membrane that must unfurl reliably in space to precise tolerances. Last week, for the first time, engineers stacked and unfurled a full-sized test unit of the Sunshield and it worked perfectly.
The Sunshield is about the length of a tennis court, and will be folded up like an umbrella around the Webb telescope’s mirrors and instruments during launch. Once it reaches its orbit, the Webb telescope will receive a command from Earth to unfold, and separate the Sunshield's five layers into their precisely stacked arrangement with its kite-like shape.

Comet C/2013 UQ4 (Catalina) has been observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet is seen glowing brightly in infrared wavelengths on July 7, 2014, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet formation 4.5 billion years ago.
C/2013 UQ4 takes more than 450 years to orbit the sun once and spends most of its time far away at very low temperatures. Its orbit is also retrograde, which means that the comet moves around the sun in the opposite direction to the planets and asteroids.
The comet was originally thought to be an asteroid, as it appeared inactive when discovered by the Catalina Sky Survey on October 23, 2013. NEOWISE also observed the comet to be inactive on New Year's Eve, 2013, but since then the comet has become highly active, allowing astronomers around the world to observe it. The comet's activity should decline as it once again returns to the cold recesses of space.
