Super Typhoon #Vongfong continued on its trek north through the Philippine Sea while slightly weakening on Oct. 10. Our TRMM and Aqua satellites provided forecasters with cloud extent, rainfall rates and distribution and more. Seen here is an image from our Terra satellite, which captured this on Oct. 10 at 2:05 UTC. This image of Typhoon Vongfong that revealed the eye had become filled with high clouds, but remained symmetrical. Feeder bands of thunderstorms wrapping into the center from the north, extended over Japan's Ryukyu Islands.

Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 Angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.

Throwback Thursday: NASA successfully completed its first rendezvous mission with two Gemini spacecraft-Gemini VII and Gemini VI-in December 1965. This photograph, taken by Gemini VI crewmembers Walter Schirra and Thomas Stafford, shows Gemini VII in orbit 160 miles (257 km) above Earth. The main purpose of Gemini VI was the rendezvous with Gemini VII. The main purpose of Gemini VII, on the other hand, was studying the long-term effects of long-duration (up to 14 days) space flight on a two-man crew. The pair also carried out 20 experiments, including medical tests. Although the principal objectives of both missions differed, they were both carried out so that NASA could master the technical challenges of getting into and working in space.

Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar – a dense stellar remnant left over from a supernova explosion – ever recorded. The discovery was made with NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. Seen here is a rare and mighty pulsar (pink) can be seen at the center of the galaxy Messier 82 in this new multi-wavelength portrait. NASA's NuSTAR mission discovered the "pulse" of the pulsar — a type of dead star — using is high-energy X-ray vision. Image credit: NASA/JPL-Caltech; -
Blood Moon! On Wednesday morning, Oct. 8th, not long before sunrise, the bright full moon over North America turned a lovely shade of celestial red. The lunar eclipse was visible from all parts of the USA. A lunar eclipse happens when the Earth casts a shadow that blocks sunlight that normally reflects off of the moon. A total lunar eclipse can only happen when the sun, Earth and moon are perfectly aligned. During the time of total eclipse, the moon will often look reddish due to red and orange light being scattered by the atmosphere. This eerie, harmless effect has earned the tongue-in-cheek nickname "blood moon." Image Credit: NASA #nasa #space #eclipse #lunareclipse #redmoon #bloodmoon #moon #earth #totallunareclipse;

Astronaut Reid Wiseman shared this image from today's spacewalk tweeting "what an experience." His fellow spacewalker, ESA astronaut Alexander Gerst also tweeted "I do not have words to describe what we did today." The duo worked outside for six hours, thirteen minutes. They installed a degraded pump module on an external stowage platform and an electrical relay system that will provide backup power to the Mobile Transporter, which can move supplies on rails along the station's backbone, and the space station's robotic arm, Canadarm2.

A Spacewalker's View: Astronaut Reid Wiseman of NASA and Alexander Gerst of ESA ended today's spacewalk at 2:43 p.m. EDT. They installed a degraded pump module on an external stowage platform and an electrical relay system that will provide backup power to the Mobile Transporter, which can move supplies on rails along the station's backbone, and the space station's robotic arm, Canadarm2. Wiseman and Gerst now have spent 6 hours and 13 minutes in space. Wiseman and NASA's Barry "Butch" Wilmore are scheduled to conduct another spacewalk on Oct. 15. Wiseman posted this image to Twitter and wrote, "The view was reasonably INSANE during the #spacewalk." Image Credit: NASA #nasa #iss #spacestation #exp41 #eva #earth #esa #space; -
Study Finds Earth’s Ocean Abyss Has Not Warmed: The cold waters of Earth’s deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years. Scientists at our Jet Propulsion Laboratory (JPL) analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably. Study coauthor Josh Willis of JPL said these findings do not throw suspicion on climate change itself. This image shows heat radiating from the Pacific Ocean as imaged by our Clouds and the Earth's Radiant Energy System instrument on the Terra satellite. (Blue regions indicate thick cloud cover.)

Our satellites stare at Typhoon #Phanfone's large eye: We captured data on Typhoon Phanfone as it continues to strengthen as it moves through the Northwestern Pacific Ocean. The Tropical Rainfall Measuring Mission or TRMM satellite flew over Typhoon Phanfone on Oct. 2, 2014 at 5:39 a.m. EDT. The rainfall pattern observed using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data showed that Phanfone was much better organized than a day earlier.

Italy from Space: Astronaut Reid Wiseman aboard the International Space Station posted this image and wrote, "#Italy, lone #lightning strike, moonlight on the Med. #Perfection." The six-person space station Expedition 41 crew conducted scientific experiments Friday, closing out a busy week focused on gearing up for two spacewalks. During the first spacewalk beginning around 8:10 a.m. EDT Tuesday, Wiseman and Alexander Gerst will exit out the Quest airlock for a six-and-a-half hour excursion. Flight Engineer Barry Wilmore, who will be inside the cupola to provide robotic support, will join Wiseman on Oct. 15 for another excursion outside the station.

Saturn's many cloud patterns, swept along by high-speed winds, look as if they were painted on by some eager alien artist. With no real surface features to slow them down, wind speeds on Saturn can top 1,100 mph (1,800 kph), more than four times the top speeds on Earth. This view looks toward the sunlit side of the rings from about 29 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on April 4, 2014 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 752 nanometers. The view was obtained at a distance of approximately 1.1 million miles (1.8 million kilometers) from Saturn. Image scale is 68 miles (109 kilometers) per pixel.

A dark snaking line in the upper right of this image on Sept. 30, 2014, show a filament of solar material hovering above the sun's surface. If straightened out, the filament would reach almost across the whole sun, about 1 million miles or 100 times the size of Earth. Solar Dynamics Observatory, or SDO, which watches the sun 24 hours a day, has observed this gigantic filament for several days as it rotated around with the sun. If straightened out, the filament would reach almost across the whole sun, about 1 million miles or 100 times the size of Earth. SDO captured the image in extreme UV light of 193 Angstrom and 335 Angstrom – different colors represent different wavelengths of light and different temperatures of solar material.

Rosetta Comet Fires Its Jets: The four images that make up this montage of comet 67P/Churyumov-Gerasimenko were taken on Sept. 26, 2014 by the European Space Agency's Rosetta spacecraft. At the time, Rosetta was about 16 miles (26 kilometers), from the center of the comet. In the montage, a region of jet activity can be seen at the neck of the comet. These jets, originating from several discrete locations, are a product of ices sublimating and gases escaping from inside the nucleus. The overlapping and slightly dissimilar angles of the four images that compose the montage are a result of the combined effect of the comet rotating between the first and last images taken in the sequence (about 10 degrees over 20 minutes), and the spacecraft movement during that same time.

Solar Flare! Our Solar Dynamics Observatory captured this image of a solar flare on Oct. 2, 2014. The solar flare is the bright flash of light on the right limb of the sun. A burst of solar material erupting out into space can be seen just below it. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

Thowback Thursday: Mission Specialist Bruce McCandless II ventured further away from the confines and safety of his ship than any previous astronaut ever has. This space first was made possible by the Manned Manuevering Unit or MMU, a nitrogen jet propelled backpack. After a series of test maneuvers inside and above Challenger's payload bay, McCandless went "free-flying" to a distance of 320 feet away from the Orbiter. The MMU is controlled by joy sticks positioned at the end of the arm rests. Moving the joy sticks left or right or by pulling them fires nitrogen jet thrusters propelling McCandless in any direction he chooses. A still camera is mounted on the upper right portion of the MMU. This stunning view shows McCandless with the MMU out there amongst the black and blue of Earth and space. Image Credit: NASA Taken: 02/11/1984 #TBT #space #history #NASA #freeflying #nasahistory;
