Backlit by the sun, Pluto's atmosphere rings its silhouette like a luminous halo in this image taken by our New Horizons spacecraft around midnight EDT on July 15. This global portrait of the atmosphere was captured when the spacecraft was about 1.25 million miles (2 million kilometers) from Pluto and shows structures as small as 12 miles across. The image, delivered to Earth on July 23, is displayed with north at the top of the frame. Credits: NASA/JHUAPL/SwRI #pluto #nasa #apl #space #newhorizons #nasabeyond #plutoflyby #science; -
[Artistic Concept] Scientists using data from NASA's Kepler mission have confirmed the first near-Earth-size planet orbiting in the habitable zone of a sun-like star. The habitable zone is the region around a star where temperatures are just right for water to exist in its liquid form. The artistic concept compares Earth (left) to the new planet, called Kepler-452b, which is about 60 percent larger. The illustration represents one possible appearance for Kepler-452b -- scientists do not know whether the planet has oceans and continents like Earth. Both planets orbit a G2-type star of about the same temperature; however, the star hosting Kepler-452b is 6 billion years old, 1.5 billion years older than our sun. As stars age, they become larger, hotter and brighter, as represented in the illustration. Kepler-452b's star appears a bit larger and brighter. Image credit: NASA/Ames/JPL-Caltech/T.

Animated Flyover of Pluto’s Icy Mountain and Plains: This simulated flyover of Pluto’s Norgay Montes (Norgay Mountains) and Sputnik Planum (Sputnik Plain) was created from New Horizons closest-approach images. Norgay Montes have been informally named for Tenzing Norgay, one of the first two humans to reach the summit of Mount Everest. Sputnik Planum is informally named for Earth’s first artificial satellite. The images were acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers). Features as small as a half-mile (1 kilometer) across are visible. Credit: NASA/JHUAPL/SWRI #nasa #pluto #plutoflyby #space #newhorizons #nasabeyond #solarsystem #science; -
Our 'EPIC' camera on @NOAA's Deep Space Climate Observatory satellite, gave us this new view of the entire sunlit side of Earth from one million miles away. This color image of Earth was taken by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope. The image was generated by combining three separate images to create a photographic-quality image. The camera takes a series of 10 images using different narrowband filters -- from ultraviolet to near infrared -- to produce a variety of science products. The red, green and blue channel images are used in these color images. The image was taken July 6, 2015, showing North and Central America. The central turquoise areas are shallow seas around the Caribbean islands. This Earth image shows the effects of sunlight scattered by air molecules, giving the image a characteristic bluish tint. The EPIC team is working to remove this atmospheric effect from subsequent images. Once the instrument begins regular data acquisition, EPIC will provide a daily series of Earth images allowing for the first time study of daily variations over the entire globe. In celebration, we're taking over @WhiteHouse on Instagram for @NASA's & @NOAA's leaders to share some of their favorite views of Earth from space. See these views of our home planet on @WhiteHouse.

Titan may be a "large" moon - its name even implies it! - but it is still dwarfed by its parent planet, Saturn. As it turns out, this is perfectly normal. Although Titan (3200 miles or 5150 km across) is the second-largest moon in the solar system, Saturn is still much bigger, with a diameter almost 23 times larger than Titan’s. This disparity between planet and moon is the norm in the solar system. Earth’s diameter is “only” 3.7 times our moon’s diameter, making our natural satellite something of an oddity. (Another exception to the rule: dwarf planet Pluto’s diameter is just under two times that of its moon.) So the question isn't why is Titan so small (relatively speaking), but why is Earth’s moon so big? This view looks toward the anti-Saturn hemisphere of Titan. North on Titan is up. The image was taken with the Cassini spacecraft wide-angle camera on April 18, 2015 using a near-infrared spectral filter with a passband centered at 752 nanometers. The view was acquired at a distance of approximately 930,000 miles (1.5 million kilometers) from Titan. Image scale is 56 miles (90 kilometers) per pixel.

Loops in Profile A whole series of loops towered above a group of active regions over a five-days period from July 9-13, 2015. When viewed in extreme ultraviolet light, magnetic field lines above the Sun's surface are revealed by charged particles that spin along the lines and create these loops. They are best observed along the edge of the Sun as they are here. The tallest of the loops reach up about 15 times the diameter of Earth.

Portrait of Pluto and its largest moon! The latest two full-frame images of the dwarf planet and its moon were collected separately by New Horizons during approach on July 13 and July 14, 2015. The relative reflectivity, size, separation, and orientations of Pluto and Charon are approximated in this composite image, and they are shown in approximate true color.

Although the Quintuplet Cluster gained its name due to its five brightest stars, it is home to hundreds more. The huge number of massive young stars in the cluster is clearly captured in this Hubble Space Telescope image. The cluster is just 100 light-years from the center of our galaxy. The Quintuplet Cluster hosts two extremely rare luminous blue variable stars: the Pistol Star, one of the most luminous known stars in the Milky Way. The exact age and future of the Pistol Star are uncertain, but it is expected to end in a supernova or even a hypernova in one to three million years. The cluster also contains a number of red supergiants, the largest in the galaxy and are burning their fuel at an incredible speed, meaning they will have a very short lifetime.

Zoom in! New from our New Horizons spacecraft: In the center left of Pluto's vast heart-shaped feature - informally named "Tombaugh Regio" - lies a vast, craterless plain that appears to be no more than 100 million years old, and is possibly still being shaped by geologic processes. This frozen region is north of Pluto's icy mountains and has been informally named Sputnik Planum (Sputnik Plain), after Earth's first artificial satellite.

Far Side of the Sun: This image of the sun was taken on Wednesday with the Extreme Ultraviolet Imager onboard our Solar TErrestrial RElations Observatory Ahead (STEREO-A) spacecraft, which collects images in several wavelengths of light that are invisible to the human eye. This image shows the sun in wavelengths of 171 angstroms, which are typically colorized in blue. STEREO-A has been on the far side of the sun since March 24, where it had to operate in safe mode, collecting and saving data from its radio instrument. The first images in over three months were received from STEREO-A on July 11. Image Credit: NASA/STEREO #nasa #nasabeyond #sun #heliophysics #stereo #earth #science; -
Remarkable new details of Pluto's largest moon Charon are revealed in this image from our New Horizons spacecraft taken late on Tuesday from a distance of 289,000 miles (466,000 kilometers). A swath of cliffs and troughs stretches about 600 miles (1,000 kilometers) from left to right, suggesting widespread fracturing of Charon's crust, likely a result of internal processes. At upper right, along the moon's curving edge, is a canyon estimated to be 4 to 6 miles (7 to 9 kilometers) deep. Mission scientists are surprised by the apparent lack of craters on Charon. South of the moon's equator, at the bottom of this image, terrain is lit by the slanting rays of the sun, creating shadows that make it easier to distinguish topography. In Charon's north polar region, a dark marking nicknamed 'Mordor' is prominent in the image. Higher resolution images still to come are expected to shed more light on this enigmatic region. New Horizons traveled more than three billion miles over nine-and-a-half years to reach the Pluto system.

You ain't seen nothing yet! Today's image was just the latest in a series of the New Horizons Pluto "picture show." Tomorrow, more images of surface close-ups will make the more than four-hour journey to Earth at the speed of light to give ten times the resolution of what we saw today, with details as small as New York's Central Park. Stay tuned! #PlutoFlyby #NASA #NASANewHorizons @NASASolarSystem #space #pluto #planet; -
SNEAK PEAK of gorgeous Pluto! The dwarf planet has sent a love note back to Earth via our New Horizons spacecraft, which has traveled more than 9 years and 3+ billion miles. This is the last and most detailed image of Pluto sent to Earth before the moment of closest approach - 7:49 a.m. EDT today. This image will be released and discussed at 8 a.m. EDT today. Watch our briefing live on NASA Television at: http://www.nasa.gov/nasatv The high res pic will be posted on the web at: http://www.nasa.gov. This stunning image of the dwarf planet was captured from New Horizons at about 4 p.m. EDT on July 13, about 16 hours before the moment of closest approach. The spacecraft was 476,000 miles (766,000 kilometers) from the surface. Image Credit: NASA #nasa #pluto #plutoflyby #newhorizons #solarsystem #nasabeyond #science;
