On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling between 1,800 and 2,200 miles per second as it left the sun. This was the fastest CME ever observed by STEREO. Two other observatories – NASA's Solar Dynamics Observatory and the joint European Space Agency/NASA Solar and Heliospheric Observatory -- witnessed the eruption as well. The July 2012 CME didn't move toward Earth, but watching an unusually strong CME like this gives scientists an opportunity to observe how these events originate and travel through space. STEREO's unique viewpoint from the sides of the sun combined with the other two observatories watching from closer to Earth. Together they helped scientists create models of the entire July 2012 event. They learned that an earlier, smaller CME helped clear the path for the larger event, thus contributing to its unusual speed. Such data helps advance our understanding of what causes CMEs and improves modeling of similar CMEs that could be Earth-directed.

King Fire in California, False-Color Infrared On Sept. 19, 2014, the Operational Land Imager (OLI) on the Landsat 8 satellite captured these images of the King fire in Eldorado National Forest. In the false-color image, burned forest appears red; unaffected forests are green; cleared forest is beige; and smoke is blue. As of Sept. 23, the blaze had charred 36,320 hectares (89,571 acres).

Sunrise at the Soyuz Launch Pad: The sun rises as the Soyuz TMA-14M spacecraft is rolled out by train to the launch pad at the Baikonur Cosmodrome, Kazakhstan, Sept. 23, 2014. Launch of the Soyuz rocket is scheduled for Sept. 25 at 4:25 p.m. EDT (Sept. 26 at 2:25 a.m. Kazakh time) and will carry Expedition 41 Soyuz Commander Alexander Samokutyaev of the Russian Federal Space Agency (Roscosmos), Flight Engineer Barry Wilmore of NASA, and Flight Engineer Elena Serova of Roscosmos into orbit to begin their five and a half month mission on the International Space Station.

An Odd Trio: The Cassini spacecraft captures a rare family photo of three of Saturn's moons that couldn't be more different from each other! As the largest of the three, Tethys (image center) is round and has a variety of terrains across its surface. Meanwhile, Hyperion (to the upper-left of Tethys) is the "wild one" with a chaotic spin and Prometheus (lower-left) is a tiny moon that busies itself sculpting the F ring. This view looks toward the sunlit side of the rings from about 1 degree above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 14, 2014. The view was acquired at a distance of approximately 1.2 million miles (1.9 million kilometers) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 22 degrees. Image scale is 7 miles (11 kilometers) per pixel.

Starry, Starry Sky from the Space Station: An Expedition 41 crew member aboard the Earth-orbiting International Space Station on Sept. 13, 2014, captured this image of a starry sky. The white panel at left belonging to the ATV-5 spacecraft, which is docked with the orbital outpost, obstructs the view of Scorpius. The red star Antares is directly to the left of the bottom of the second ATV panel from the top. The two stars that are close together and on the lower left of the photo comprise Shaula, the tip of the scorpionâ€s tail. The open cluster close to Shaula is M7. The hardware at bottom right is part of one of the station's solar panels. Image Credit: NASA #nasa #esa #atv #iss #spacestation #exp41 #earth #stars #space #science; -
Hubble Feathers the Peacock: This picture, taken by our Hubble Space Telescope's Wide Field Planetary Camera 2 (WFPC2), shows a galaxy known as NGC 6872 in the constellation of Pavo (The Peacock). Its unusual shape is caused by its interactions with the smaller galaxy that can be seen just above NGC 6872, called IC 4970. They both lie roughly 300 million light-years away from Earth. From tip to tip, NGC 6872 measures over 500,000 light-years across, making it the second largest spiral galaxy discovered to date. In terms of size it is beaten only by NGC 262, a galaxy that measures a mind-boggling 1.3 million light-years in diameter! To put that into perspective, our own galaxy, the Milky Way, measures between 100,000 and 120,000 light-years across, making NGC 6872 about five times its size.

Our Airborne Campaigns Focus on Climate Impacts in the Arctic: This red plane is a DHC-3 Otter, the plane flown in our Operation IceBridge-Alaska surveys of mountain glaciers in Alaska. Over the past few decades, average global temperatures have been on the rise, and this warming is happening two to three times faster in the Arctic. As the region's summer comes to a close, We're hard at work studying how rising temperatures are affecting the Arctic. Our researchers this summer and fall are carrying out three Alaska-based airborne research campaigns aimed at measuring greenhouse gas concentrations near Earth's surface, monitoring Alaskan glaciers, and collecting data on Arctic sea ice and clouds. Observations from these campaigns will give researchers a better understanding of how the Arctic is responding to rising temperatures.

Our Hubble Space Telescope finds big surprise in teeny tiny galaxy: A supermassive black hole with a mass 21 million times our sun. The black hole is five times the mass of the one at the center of our Milky Way galaxy. It is inside one of the densest galaxies known to date -- the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter. If you lived inside this dwarf galaxy, the night sky would dazzle with at least 1 million stars visible to the naked eye. Our nighttime sky as seen from Earth’s surface shows 4,000 stars. This is an artist's view of M60-UCD1 black hole. Image Credit: NASA, ESA, STScI-RCC14-41a #nasa #space #galaxy #milkyway #blackhole #astronomy #stars #hubble #hst #telescope #science;
