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.

Mountains on Pluto! This movie zooms into the base of the heart-shaped feature on Pluto to highlight a new image captured by our New Horizons spacecraft. The new image, seen in black and white against a previously released color image of Pluto, shows a mountain range with peaks jutting as high as high as 11,000 feet (3,500 meters) above the surface of the icy body.

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;

Three billion miles from Earth and just two and a half million miles from Pluto, NASA’s New Horizons spacecraft has taken its best image of four dark spots that continue to captivate. At 7:49 AM EDT on Tuesday, July 14 New Horizons will zip past Pluto at 30,800 miles per hour (49,600 kilometers per hour), with a suite of seven science instruments busily gathering data. The mission will complete the initial reconnaissance of the solar system with the first-ever look at the icy dwarf planet. Credit: NASA #nasa #space #pluto #plutoflyby #nasabeyond #science; -
Stunning Spiral Galaxy! This little-known galaxy is a classic example of a spiral galaxy. The galaxy is much like our own galaxy, the Milky Way. The disk-shaped galaxy is seen face on, revealing the winding structure of the spiral arms. Dark patches in these spiral arms are in fact dust and gas — the raw materials for new stars. The many young stars that form in these regions make the spiral arms appear bright and bluish. Image credit: ESA/Hubble & NASA #nasa #hubble #hubble25 #nasabeyond #space #galaxy #science; -
They're a fascinating pair: Two icy worlds, spinning around their common center of gravity like a pair of figure skaters clasping hands. Scientists believe they were shaped by a cosmic collision billions of years ago, and yet, in many ways, they seem more like strangers than siblings. A high-contrast array of bright and dark features covers Pluto's surface, while on Charon, only a dark polar region interrupts a generally more uniform light gray terrain. The reddish materials that color Pluto are absent on Charon. Pluto has a significant atmosphere; Charon does not. On Pluto, exotic ices like frozen nitrogen, methane, and carbon monoxide have been found, while Charon's surface is made of frozen water and ammonia compounds. The interior of Pluto is mostly rock, while Charon contains equal measures of rock and water ice. On Tuesday, our New Horizons spacecraft will make its closest approach to Pluto. Standby for more never-before seen images of Pluto! Image Credit: NASA #nasa #space #newhorizons #pluto #plutoflyby #charon #nasabeyond #science; -
Flaring, active regions of our sun are highlighted in this new image combining observations from several telescopes. High-energy X-rays from our Nuclear Spectroscopic Telescope Array (NuSTAR) are shown in blue; low-energy X-rays from Japan's Hinode spacecraft are green; and extreme ultraviolet light from our Solar Dynamics Observatory (SDO) is yellow and red. All three telescopes captured their solar images around the same time on April 29, 2015. The NuSTAR image is a mosaic made from combining smaller images. The active regions across the sun's surface contain material heated to several millions of degrees. Image credit: NASA/JPL-Caltech/GSFC/JAXA #nasa #sun #nustar #nasabeyond #hinode #sdo #science; -
Only 8 days until our New Horizons spacecraft flies by Pluto! And new high-resolution views of Pluto were just released! One image includes the four mysterious dark spots on Pluto that have captured the imagination of the world. The Long Range Reconnaissance Imager (LORRI) obtained the images prior to the July 4 anomaly that sent New Horizons into safe mode. This color version of the July 3 LORRI image was created by adding color data from the Ralph instrument gathered earlier in the mission.

Happy 4th of July! While fireworks only last a short time here on Earth, a bundle of cosmic sparklers in a nearby cluster of stars will be going off for a very long time. This is a star cluster populated with many young stars that are less than 2 million years old, a blink of an eye in astronomical terms for stars like the Sun expected to burn for billions of years.

Happy 4th of July! We present some stellar fireworks! Stars are essentially giant fusion reactions occurring in the vacuum of space. Because stars have so much mass, they possess powerful gravitational force-but they don't collapse because of the outward force generated by nuclear fusion, continually converting hydrogen atoms to helium. Sometimes stars begin orbiting each other, forming a binary star system. Typically this involves a white dwarf star and a red giant. Orbiting the red giant like a moon, the dwarf star rips matter from its companion until it essentially gags on the excess, coughing hot gas and radiation into space. This dramatic phenomenon is relatively common, and the white dwarf is not destroyed in the resulting nova.

This Hubble Space Telescope picture shows a galaxy named SBS 1415+437 (also called SDSS CGB 12067.1), located about 45 million light-years from Earth. SBS 1415+437 is a Wolf-Rayet galaxy, a type of star-bursting galaxy with an unusually high number of extremely hot and massive stars known as Wolf-Rayet stars. These stars can be around 20 times as massive as the sun, but seem to be on a mission to shed surplus mass as quickly as possible - they blast substantial winds of particles out into space, causing them to dwindle at a rapid rate. A typical star of this type can lose a mass equal to that of our sun in just 100,000 years! Image credit: ESA/Hubble & NASA #nasa hubble #hst #hubble25 #space #galaxy #astronomy #science; -
New Pluto images from our New Horizons spacecraft show two very different faces of the mysterious dwarf planet, one with a series of intriguing spots along the equator that are evenly spaced. Each of the spots is about 300 miles in diameter, with a surface area that's roughly the size of the state of Missouri. Scientists have yet to see anything quite like the dark spots; their presence has piqued the interest of the New Horizons science team, due to the remarkable consistency in their spacing and size. While the origin of the spots is a mystery for now, the answer may be revealed as the spacecraft continues its approach - July 14 is the flyby - to the mysterious dwarf planet.
