NASA's Swift Catches X-ray Action at Milky Way's Center - Recent observations by NASA's Swift spacecraft have provided scientists a unique glimpse into the activity at the center of our galaxy and led to the discovery of a rare celestial entity that may help them test predictions of Albert Einstein's theory of general relativity. This week, at the annual meeting of the American Astronomical Society in National Harbor, Md., scientists presented their research into images captured by Swift, explaining how these images will help decipher the physical nature of X-ray flares and enabled their discovery of a rare subclass of neutron star. Swift's seven-year campaign to monitor the center of the Milky Way has doubled the number of images available to scientists of bright X-ray flares occurring at the galaxy's central black hole, dubbed Sagittarius A* (Sgr A*). Sgr A* sits in the center of the Milky Way's innermost region, 26,000 light-years away in the direction of the constellation Sagittarius. Its mass is at least 4 million times that of the sun. Despite its considerable size, it is not nearly as bright as it could be if it was more active, according to one expert. This X-ray image of the galactic center merges Swift XRT observations through 2013. Sgr A* is at center. Low-energy X-rays (300 to 1,500 electron volts) are shown in red, medium-energy (1,500 to 3,000 eV) in green, and high-energy (3,000 to 10,000 eV) in blue. The total exposure time is 12.6 days.

Sun Unleashes First X-class Flare of 2014, Delaying Rocket Launch - The sun emitted a significant solar flare peaking at 1:32 p.m. EST on Jan.7, 2014. This is the first significant flare of 2014, and follows on the heels of mid-level flare earlier in the day. Each flare was centered over a different area of a large sunspot group currently situated at the center of the sun, about half way through its 14-day journey across the front of the disk along with the rotation of the sun. Early this morning, Orbital Sciences Corp. decided to scrub today’s launch attempt of the Antares rocket and the Cygnus cargo spacecraft on the company’s first resupply mission to the International Space Station due to an unusually high level of space radiation that exceeded constraints imposed on Antares. The solar flux activity resulted in an increasing level of radiation beyond what the Antares engineering team monitored earlier in the day. At Mission Control in Houston, the flight control team reported that the ISS crew is not affected by this solar event and does not require any special precautionary measures. 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. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours. This pictures combines two images from NASA's Solar Dynamics Observatory captured on Jan. 7, 2013.

'Twas the night before launch… An Orbital Sciences Corporation Antares rocket is seen on launch Pad-0A at NASA's Wallops Flight Facility on the evening of Tuesday, Jan. 7, 2014 in advance of a planned Wednesday, Jan. 8th, 1:32 p.m. EST launch. The Antares will launch a Cygnus spacecraft on a cargo resupply mission to the International Space Station. The Orbital-1 mission is Orbital Sciences' first contracted cargo delivery flight to the space station for NASA. Among the cargo aboard Cygnus set to launch to the space station are science experiments, crew provisions, spare parts and other hardware. There is a 95 percent chance of favorable weather at the time of launch. High, thick clouds are the primary concern for a weather violation. If needed, multiple back-up launch opportunities are available through Jan. 12. Live launch coverage on Jan. 8 will be carried live on NASA TV and the agency's website at www.nasa.gov/ntv beginning at 1:00 p.m. EST (18:00 UCT).

This long-exposure Hubble Space Telescope image of massive galaxy cluster Abell 2744 (foreground) is the deepest ever made of any cluster of galaxies. It shows some of the faintest and youngest galaxies ever detected in space. Abell 2744 is a massive galaxy cluster located in the constellation Sculptor. The immense gravity in Abell 2744 is being used as a lens to warp space and brighten and magnify images of more distant background galaxies. The more distant galaxies appear as they did longer than 12 billion years ago, not long after the big bang. The Hubble exposure reveals nearly 3,000 of these background galaxies interleaved with images of hundreds of foreground galaxies in the cluster. NASA's Hubble Space Telescope is providing a new perspective on the remote universe, including new views of young and distant galaxies bursting with stars. Scientists described the findings Tuesday in a news conference sponsored by the American Astronomical Society (AAS).

NEOWISE's New Find - The three red dots in this composite picture indicate the location of the first new near-Earth asteroid seen by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) since the spacecraft came out of hibernation in December 2013. The asteroid, called 2013 YP139, is the first of hundreds of space-rock discoveries expected during its renewed mission. The inset shows a zoomed-in view of one of the detections of 2013 YP139. 2013 YP139 was discovered by NEOWISE on Dec. 29, 2013. The mission's sophisticated software picked out the moving object against a background of stationary stars. Near-Earth objects are asteroids and comets with orbits that come close to Earth's path around the sun. 2013 YP139, is currently about 27 million miles (43 million kilometers) from Earth. Based on its infrared brightness, scientists estimate it to be approximately 0.4 miles (650 meters) in diameter and extremely dark. Because NEOWISE is an infrared telescope, it senses heat from asteroids. 2013 YP139 is as dark as a piece of coal, and it glows brightly at infrared wavelengths. The shortest infrared wavelength, 3.4 microns, is color-coded blue, and the longer wavelength, 4.6 microns, is color-coded red. The asteroid appears as a string of red dots because it is much cooler than the stars. Stars are thousands of degrees, but the asteroid is close to room temperature, so it is red in these images. While asteroid 2013 YP139 orbits the sun in an elliptical orbit nearly in the plane of our solar system and is classified as a potentially hazardous asteroid, it is not likely to approach within Earth's vicinity anytime over the next 100 years. However, the asteroid’s future motion can bring it within about 300,000 miles (490,000 kilometers) of Earth’s orbit, so its long-term motion will be closely monitored.

Stormy Stars? This Just In: Storms Expected on Brown Dwarfs - This artist's concept shows what the weather might look like on cool star-like bodies known as brown dwarfs. These giant balls of gas start out life like stars, but lack the mass to sustain nuclear fusion at their cores, and instead, fade and cool with time. New research from NASA's Spitzer Space Telescope suggests that most brown dwarfs are racked with colossal storms akin to Jupiter's famous "Great Red Spot." These storms may be marked by fierce winds, and possibly lightning. The turbulent clouds might also rain down molten iron, hot sand or salts -- materials thought to make up the cloud layers of brown dwarfs.

Polar Vortex Enters Northern U.S. - The polar vortex is a whirling and persistent large area of low pressure, found typically over both North and South poles. The northern polar vortex was pushing southward over western Wisconsin and eastern Minnesota on Monday, Jan. 6, 2014, and was bringing frigid temperatures to half of the continental United States. It is expected to move northward back over Canada toward the end of the week. This image was captured by NOAA's GOES-East satellite on Jan. 6, 2014, at 11:01 a.m. EST (1601 UTC). A frontal system that brought rain to the coast is draped from north to south along the U.S. East Coast. Behind the front lies the clearer skies bitter cold air associated with the polar vortex. The image also revealed snow on the ground in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Michigan, Iowa and Missouri, stretching into the Great Plains. Clouds over Texas are associated with a low pressure system centered over western Oklahoma that is part of the cold front connected to the movement of the polar vortex. The GOES image was created at NASA's GOES Project, located at NASA's Goddard Space Flight Center in Greenbelt, Md. Both the northern and southern polar vortexes are located in the middle and upper troposphere (lowest level of the atmosphere) and the stratosphere (next level up in the atmosphere). The polar vortex is a winter phenomenon. It develops and strengthens in its respective hemispheres’ winters as the sun sets over the polar region and temperatures cool. They weaken in the summer. In the Northern Hemisphere, they circulate in a counterclockwise direction, so the vortex sitting over western Wisconsin is sweeping in cold Arctic air around it.

NASA's Fermi Makes First Gamma-ray Study of a Gravitational Lens - An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source. This accomplishment opens new avenues for research, including a novel way to probe emission regions near supermassive black holes. It may even be possible to find other gravitational lenses with data from the Fermi Gamma-ray Space Telescope. Fermi detected a series of bright gamma-ray flares from a source known as B0218+357, located 4.35 billion light-years from Earth in the direction of a constellation called Triangulum. These powerful flares, in a known gravitational lens system, provided the key to making the lens measurement. Astronomers classify B0218+357 as a blazar -- a type of active galaxy noted for its intense emissions and unpredictable behavior. At the blazar's heart is a supersized black hole with a mass millions to billions of times that of the sun. As matter spirals toward the black hole, some of it blasts outward as jets of particles traveling near the speed of light in opposite directions. This Hubble image of gravitational lens B0218+357 reveals two bright sources separated by about a third of an arcsecond, each an image of the background blazar. Spiral arms belonging to the lensing galaxy also can be seen. B0218+357 boasts the smallest separation of lensed images currently known.

Alternative Fuel Studies Take Flight: Following a series of ground tests completed in 2010 and 2012, NASA began a series of flight tests in 2013 to study emissions from new blends of aviation gas that includes biofuel from renewable sources. NASA researchers are investigating the effect that a 50-50 blend of alternate biofuel has on jet engine performance, emissions and aircraft-generated contrails at altitude. The research involved flying NASA's DC-8 as high as 40,000 feet while an instrumented NASA Falcon HU-25 aircraft trailed behind at distances ranging from 300 feet to more than 10 miles. Preliminary results indicate that the bio fuel blends tested may substantially reduce the emission of black carbon, sulfates and organics. Future research will further study the impact that using bio fuel blends has on the formation of aircraft contrails. A second phase of ACCESS flights is planned for 2014. Seen here is the puffy white exhaust contrails stream from the engines of NASA's DC-8 flying laboratory during tests of alternative jet engine fuel emissions.

Japanese Astronaut Koichi Wakata shared this image from the International Space Station on Twitter this Saturday morning saying "the sun does not set on low earth orbit for another few days as the ISS is tracking parallel to the terminator." The expansive International Space Station is a working laboratory orbiting 260 miles above the Earth, traveling at 17,500 mph, and is home to an international crew. It is the most complex scientific and technological endeavor ever undertaken. As a research outpost, the station is a test bed for future technologies and a research laboratory for new, advanced industrial materials, communications technology, medical research and much more.

Mars Exploration Rover Spirit's Selfie: The twin Mars Exploration Rovers Spirit and Opportunity were launched toward Mars in June and July of 2003. They arrived months later in spectacular fashion, bouncing down safely on the surface after a harrowing six-minute descent through the thin atmosphere. Spirit arrived on January 3, 2004, 10 years ago. Spirit operated for more than six years after landing for what was planned as a three-month mission. This bird's-eye view combines a self-portrait of the spacecraft deck and a panoramic mosaic of the Martian surface as viewed by Spirit. The rover's solar panels are still gleaming in the sunlight, having acquired only a thin veneer of dust two years after the rover landed and commenced exploring the red planet. Spirit captured this 360-degree panorama on the summit of "Husband Hill" inside Mars' Gusev Crater. During the period from Spirit's Martian days, or sols, 583 to 586 (Aug. 24 to 27, 2005), the rover's panoramic camera acquired the hundreds of individual frames for this largest panorama ever photographed by Spirit. This image is an approximately true-color rendering using the camera's 750-nanometer, 530-nanometer and 480-nanometer filters for the Martian surface, and the 600-nanometer, 530-nanometer, and 480-nanometer filters for the rover deck. This polar projection is a compromise between a cylindrical projection, which provides the best view of the terrain, and a vertical projection, which provides the best view of the deck but distorts the terrain far from the rover. The view is presented with geometric seam correction. Image Credit: NASA/JPL-Caltech/Cornell #rover #marsrover #spirit #marsrovers #mars #planets #redplanet #nasa #space #solarsystem;
