It's not often that the Winter Olympic Games come with an ocean view, but that's what we are getting this year at the Black Sea resort of Sochi, Russia. Sochi is the warmest city ever to host the winter games, which officially run from Feb. 7 through Feb. 23. This image of the Sochi Olympic venues was acquired on Jan. 4, 2014, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft. The Olympic Park Coastal Cluster for indoor sports appears as a circular area on the shoreline in the bottom center of the image. There's a separate arena for curling, alongside multiple arenas for hockey and skating. The actual city of Sochi, which has a population of about 400,000, is not visible in the picture. In this images, red indicates vegetation, white is snow, buildings appear in gray, and the ocean is dark blue.

Orion Stage Adapter Aces Structural Loads Testing: A test article of the stage adapter that will connect the Orion spacecraft to a United Launch Alliance (ULA) Delta IV rocket for its first mission, Exploration Flight Test-1, aced structural loads testing Jan. 30. Now, the stage adapter that will fly on the Delta IV is officially ready for the journey to its final exam -- a flight more than 15 times farther into deep space than the International Space Station. For the structural loads test, the hardware was attached with lines running in different directions on the hardware. Hydraulic pressure was added to those lines in increments, which pushed on the adapter to evaluate its integrity. The test was similar to the recent "can-crush" tests on a rocket fuel tank, but the adapter wasn't purposefully buckled for the structural test as it was on the fuel tank. Twenty-five test cases were completed on the adapter. Image credit: NASA/MSFC/David Olive #nasa #orion #eft1 #exploration #flighttest #rockets #deltaiv #launch #space; -
Just weeks after NASA’s Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A. This galaxy, at a distance of about 12 million light years from Earth, contains a gargantuan jet blasting away from a central supermassive black hole. Since then, Chandra has returned its attention to this galaxy, each time gathering more data. And, like an old family photo that has been digitally restored, new processing techniques are providing astronomers with a new look at this old galactic friend. As in all of Chandra’s images of Cen A, this one shows the spectacular jet of outflowing material – seen pointing from the middle to the upper left – that is generated by the giant black hole at the galaxy’s center. This new high-energy snapshot of Cen A also highlights a dust lane that wraps around the waist of the galaxy. Astronomers think this feature is a remnant of a collision that Cen A experienced with a smaller galaxy millions of years ago. Image credit: X-ray: NASA/CXC/U. Birmingham/M.

Crescent Moon Rising and Earth's Atmosphere - On Feb. 1, 2014, Japan Aerospace Exploration Agency astronaut Koichi Wakata tweeted this view of a crescent moon rising and the cusp of Earth's atmosphere. Distinct colors are visible because the dominant gases and particles in each layer of the atmosphere act as prisms, filtering out certain colors of light.

A Spectacular New Martian Impact Crater - A dramatic, fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Nov. 19, 2013. Researchers used HiRISE to examine this site because the orbiter's Context Camera had revealed a change in appearance here between observations in July 2010 and May 2012, bracketing the formation of the crater between those observations. The crater spans approximately 100 feet (30 meters) in diameter and is surrounded by a large, rayed blast zone. Because the terrain where the crater formed is dusty, the fresh crater appears blue in the enhanced color of the image, due to removal of the reddish dust in that area. Debris tossed outward during the formation of the crater is called ejecta. In examining ejecta's distribution, scientists can learn more about the impact event. The explosion that excavated this crater threw ejecta as far as 9.3 miles (15 kilometers). Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space #mars #crater #science #planets;

Today in 1974, NASA's Mariner 10 mission took this first close-up photo of Venus. Made using an ultraviolet filter in its imaging system, the photo has been color-enhanced to bring out Venus's cloudy atmosphere as the human eye would see it. Venus is perpetually blanketed by a thick veil of clouds high in carbon dioxide and its surface temperature approaches 900 degrees Fahrenheit. Launched on Nov. 3, 1973 atop an Atlas-Centaur rocket, Mariner 10 flew by Venus in 1974. #nasa #space #science #venus #atlas; -

Sun Emits Mid-Level Solar Flare: The sun emitted a mid-level solar flare, beginning at 11:57 p.m. EST on Feb. 3, 2014, and peaking at midnight EST. This image, captured by NASA's Solar Dynamics Observatory, shows the bright flare near the center of the sun. 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 flare is classified as an M5.2 flare. Image Credit: NASA/SDO #sdo #sun #solar #solarflare #sunspot #solarsystem #nasa #science; -
In the bright light of Antarctica's summer sun, a NASA mission launched its first 18 science balloons between Dec. 27, 2013, and Feb. 2, 2014. BARREL, or the Balloon Array for Radiation belt Relativistic Electron Losses, plans to launch 20 balloons in total to help unravel the mysterious radiation belts, two gigantic donuts of particles that surround Earth. Once launched, each balloon travels in a wide circle around the South Pole for up to three weeks, so that a handful of balloons can be up at any one time. Circling the pole, the balloons fly through the foot point of where Earth's magnetic fields descend down to the ground. Instruments on the balloons observe electrons traveling down from space along these fields. By coordinating with NASA's Van Allen Probes – two spacecraft orbiting high above -- the team hopes to determine what occurrence in the belts correlates to occasional bursts of electrons that can precipitate down toward Earth. Such information will ultimately help scientists understand -- and predict changes -- in the Van Allen radiation belts. This image is of a BARREL balloon launch at Halley Research Station on Jan. 30, 2014.

NASA's Curiosity Mars rover reached the edge of a dune on Jan. 30 and photographed the valley on the other side, to aid assessment of whether to cross the dune. Curiosity is on a southwestward traverse of many months from an area where it found evidence of ancient conditions favorable for microbial life to its long-term science destination on the lower slopes of Mount Sharp. Based on analysis of images taken from orbit by NASA's Mars Reconnaissance Orbiter, a location dubbed "Dingo Gap" was assessed as a possible gateway to a favorable route for the next portion of the traverse. A dune across Dingo Gap is about 3 feet (1 meter) high, tapered off at both sides of the gap between two low scarps. Curiosity reached the eastern side of the dune on Jan. 30 and returned images that the rover team is using to guide decisions about upcoming drives.

While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life. Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules that are critical for life. Researchers have analyzed carbon-rich meteorites (carbonaceous chondrites) and found amino acids, which are used to make proteins. Proteins are among the most important molecules in life, used to make structures like hair and skin, and to speed up or regulate chemical reactions. They have also found components used to make DNA, the molecule that carries the instructions for how to build and regulate a living organism, as well as other biologically important molecules like nitrogen heterocycles, sugar-related organic compounds, and compounds found in modern metabolism. Picture here is the equipment used by NASA Goddard's Astrobiology Analytical Lab to analyze very small samples. On the right is the nanoelectrospray emitter, which gives sample molecules an electric charge and transfers them to the inlet of the mass spectrometer (left), which identifies the molecules by their mass. This technology and the laboratory techniques that the Goddard lab develops to apply it to analyze meteorites will be valuable for future sample-return missions since the amount of sample likely will be limited.

Round and Round - Just as Saturn's famous hexagonal shaped jet stream encircles the planet's north pole, the rings encircle the planet, as seen from Cassini's position high above. Around and around everything goes! This view looks toward the sunlit side of the rings from about 43 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on Nov. 23, 2013 using a spectral filter that preferentially admits wavelengths of near-infrared light centered at 752 nanometers.

Game over & so is #SupernovaSunday. We hope you enjoyed it! This highly distorted supernova remnant may contain the most recent black hole formed in the Milky Way galaxy. The composite image combines X-rays from Chandra (blue and green), radio data from the Very Large Array (pink), and infrared data from the Palomar Observatory (yellow). Most supernova explosions that destroy massive stars are generally symmetrical. In the W49B supernova, however, it appears that the material near its poles was ejected at much higher speeds than that at its equator. There is also evidence that the explosion that produced W49B left behind a black hole and not a neutron star like most other supernovas.

The scoreboard may not be lighting up, but this artist's illustration shows what the brightest supernova ever recorded, known as SN 2006gy, may have looked like. The fireworks-like material (white) shows the explosive death of an extremely massive star. Before it exploded, the star expelled the lobes of cool gas (red). As the material from the explosion crashes into the lobes, it heats the gas in a shock front (green, blue and yellow) and pushes it backward.

In honor of the Super Bowl Half Time Show and Bruno Mars… well, here’s Mars. Mosaic of the Syrtis Major hemisphere of Mars projected into a point perspective, a view similar to that which one would see from a spacecraft. The viewer's distance is 2,000 kilometers above the surface of the planet. This mosaic is composed of about 100 red and violet filter Viking Orbiter images. The images were acquired in 1980 during early northern summer on Mars.
