Darkness descending... Saturn's unusual appearance in this picture is a result of the planet being imaged via an infrared filter. Infrared images can help scientists determine the location of clouds in the planet's atmosphere. In this image, Cassini's wide-angle camera used a filter which is especially sensitive to infrared wavelengths that are absorbed by methane. Methane is not a major component of Saturn's atmosphere, but enough of it is present to make a difference in how much light is reflected by different clouds. The darker areas reveal clouds that are lower in the atmosphere, therefore under more methane. Bright areas on Saturn are higher altitude clouds. Scientists think that these lower-altitude clouds are in regions where "air" is descending while the higher-altitude clouds are in regions where air is rising. Thus, images like this one can help us map the vertical air movements on Saturn. Credit: NASA/JPL-Caltech/Space Science Institute #nasa #nasabeyond #cassini #space #solarsystem #saturn #science; -
That’s one small bite for a man, one giant leaf for mankind: Today, astronauts Scott Kelly, Kjell Lindgren and Kimiya Yui of Japan sample the fruits of their labor after harvesting a crop of “Outredgeous” red romaine lettuce from the Veggie plant growth system on the International Space Station. They are the first people to eat food grown in space. We’re maturing Veggie technology aboard the space station to provide future pioneers with a sustainable food supplement – a critical part of our Journey to Mars. As we move toward long-duration exploration missions farther into the solar system, Veggie will be a resource for crew food growth and consumption. It also could be used by astronauts for recreational gardening activities during deep space missions. Credit: NASA #iss space spacestation nasa journeytomars yearinspace; -
Before drifting off to sleep tonight aboard the International Space Station, astronaut Scott Kelly (@stationcdrkelly) posted this image and wrote, "Day 135. #MilkyWay. You're old, dusty, gassy and warped. But beautiful. Good night from @ISS! #YearInSpace" Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission. Traveling the world more than 220 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day. Image Credit: NASA #nasa #iss #spacestation #space #isscrew; -
Hubble Finds a Little Gem: This colorful bubble is a planetary nebula called NGC 6818, also known as the Little Gem Nebula. It is located in the constellation of Sagittarius (The Archer), roughly 6,000 light-years away from us. The rich glow of the cloud is just over half a light-year across - humongous compared to its tiny central star - but still a little gem on a cosmic scale.

Aboard the International Space Station, astronaut Scott Kelly (@stationcdrkelly) posted this image and wrote, "The view out my window this morning. #Typhoon #Soudelor still looking ominous from @ISS. #YearInSpace." Clouds in Typhoon Soudelor's western quadrant were already spreading over Taiwan early on Aug. 7. Soudelor is expected to make landfall and cross central Taiwan today and make a second landfall in eastern China. Image Credit: NASA #nasa #iss #spacestation #space #storm;

Stormy Seas in Sagittarius: Some of the most breathtaking views in the Universe are created by nebulae - hot, glowing clouds of gas. This new NASA/ESA Hubble Space Telescope image shows the center of the Lagoon Nebula, an object with a deceptively tranquil name, in the constellation of Sagittarius. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.

The far side of the moon, illuminated by the sun, is seen as it crosses between our 'EPIC' camera on the Deep Space Climate Observatory (DSCOVR) satellite, and the Earth - one million miles away. This image was captured by NASA's Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope on the DSCOVR satellite orbiting 1 million miles from Earth. From its position between the sun and Earth, DSCOVR conducts its primary mission of real-time solar wind monitoring for the National Oceanic and Atmospheric Administration (NOAA).

The largest and most powerful hurricanes ever recorded on Earth spanned over 1,000 miles across with winds gusting up to around 200 mph. That's wide enough to stretch across nearly all U.S. states east of Texas. But even that kind of storm is dwarfed by the Great Red Spot, a gigantic storm in Jupiter. There, gigantic means twice as wide as Earth. With tumultuous winds peaking at about 400 mph, the Great Red Spot has been swirling wildly over Jupiter's skies for the past 150 years-maybe even much longer than that. While people saw a big spot in Jupiter as early as they started stargazing through telescopes in the 1600s, it is still unclear whether they were looking at a different storm. Today, scientists know the Great Red Spot is there and it's been there for a while, but they still struggle to learn what causes its swirl of reddish hues.

Streaming Push and Pull: Elongated streams of plasma zipped back and forth along magnetic field lines above several active regions on the sun on July 26-27, 2015. This kind of activity is rather common, but interesting to watch up close as the streams of particles twist and turn and zip back and forth. The images were taken of ionized Helium heated to 60,000 degrees C. in 304 wavelength of extreme ultraviolet light.

Look closely & don't miss it! The International Space Station, with a crew of six onboard, is seen in silhouette as it transits the moon at roughly five miles per second, Sunday, Aug. 2, 2015, Woodford, VA. Onboard are: NASA astronauts Scott Kelly and Kjell Lindgren: Russian Cosmonauts Gennady Padalka, Mikhail Kornienko, Oleg Kononenko, and Japanese astronaut Kimiya Yui.

A dying star's final moments are captured in this image from the Hubble Space Telescope. The death throes of this star may only last mere moments on a cosmological timescale, but this star's demise is still quite lengthy by our standards, lasting tens of thousands of years! The star's agony has culminated in a wonderful planetary nebula known as NGC 6565, a cloud of gas that was ejected from the star after strong stellar winds pushed the star's outer layers away into space. Once enough material was ejected, the star's luminous core was exposed, enabling its ultraviolet radiation to excite the surrounding gas to varying degrees and causing it to radiate in an attractive array of colors. These same colors can be seen in the famous and impressive Ring Nebula (heic1310), a prominent example of a nebula like this one. Planetary nebulae are illuminated for around 10,000 years before the central star begins to cool and shrink to become a white dwarf. When this happens, the star's light drastically diminishes and ceases to excite the surrounding gas, so the nebula fades from view.

In honor of tonight's 'Blue Moon,' astronaut Scott Kelly aboard the International Space Station posted this image and wrote, "TGIF Here's a preview of tonight's rare celestial surprise. #BlueMoon on the rise. #YearInSpace."

Using NASA's Spitzer Space Telescope, astronomers have confirmed the discovery of the nearest rocky planet outside our solar system, larger than Earth and a potential gold mine of science data. Dubbed HD 219134b, this exoplanet, which orbits too close to its star to sustain life, is a mere 21 light-years away. While the planet itself can't be seen directly, even by telescopes, the star it orbits is visible to the naked eye in dark skies in the Cassiopeia constellation, near the North Star. HD 219134b is also the closest exoplanet to Earth to be detected transiting, or crossing in front of, its star and, therefore, perfect for extensive research. This artist's concept video shows the silhouette of the rocky planet crossing, or transiting, its star. Video Credits: NASA/JPL-Caltech; -
We dropped a Cessna 172 from 100 feet today. With a thunderous rattle, the aircraft plowed into the soil as its windshield shattered, its wings wrenched off and its fuselage flipped -- tail over nose -- onto its back. Researchers were pleased. The controlled experiment that will help us improve aviation emergency response times. We’re developing next-gen search and rescue technology as part of an international effort involving members from 43 countries and organizations.
