Four laser beams cut across this startling image of the Orion Nebula, as seen from ESO's Paranal Observatory in the Atacama desert on planet Earth. Not part of an interstellar conflict, the lasers are being used for an observation of Orion by UT4, one of the observatory's very large telescopes, in a technical test of an image-sharpening adaptive optics system. This view of the nebula with laser beams was captured by a small telescope from outside the UT4 enclosure. The beams are visible from that perspective because in the first few kilometers above the observatory the Earth's dense lower atmosphere scatters the laser light. The four small segments appearing beyond the beams are emission from an atmospheric layer of sodium atoms excited by the laser light at higher altitudes of 80-90 kilometers. Seen from the perspective of the UT4, those segments form bright spots or artificial guide stars. Their fluctuations are used in real-time to correct for atmospheric blurring along the line-of-sight by controlling a deformable mirror in the telescope's optical path. via NASA ift.tt/2nw3RIa

NASA's Mars Exploration Rover Opportunity is continuing its traverse southward on the western rim of Endeavour Crater during the fall of 2014, stopping to investigate targets of scientific interest along way. This view is from Opportunity's front hazard avoidance camera on Nov. 26, 2014, during the 3,854th Martian day, or sol, of the rover's work on Mars. This camera is mounted low on the rover and has a wide-angle lens. The scene includes Opportunity's robotic arm, called the "instrument deployment device," at upper left. Portions of the pale bedrock exposed on the ground in front of the rover are within the arm's reach. Researchers used instruments on the arm to examine a target called "Calera" on this patch of bedrock. The wheel tracks in the scene are from the drive -- in reverse -- to this location, a drive of 32.5 feet (9.9 meters) on Sol 3846 (Nov. 18, 2014).

Glaciers and mountains in the evening sun are seen on an Operation IceBridge research flight, returning from West Antarctica on Oct. 29, 2014. NASA is carrying out its sixth consecutive year of Operation IceBridge research flights over Antarctica to study changes in the continent’s ice sheet, glaciers and sea ice. This year’s airborne campaign revisits a section of the Antarctic ice sheet that recently was found to be in irreversible decline. IceBridge uses a suite of instruments that includes a laser altimeter, radar instruments, cameras, and a gravimeter, which is an instrument that detects small changes in gravity. These small changes reveal how much mass these glaciers have lost. Researchers plan to measure previously unsurveyed regions of Antarctica, such as the upper portions of Smith Glacier in West Antarctica, which is thinning faster than any other glaciers in the region. The mission also plans to collect data in portions of the Antarctic Peninsula, such as the Larsen C, George VI and Wilkins ice shelves and the glaciers that drain into them. The Antarctic Peninsula has been warming faster than the rest of the continent. In addition to extending the data record of NASA’s Ice, Cloud and Land Elevation Satellite (ICESat), which stopped collecting data in 2009, IceBridge will also help set the stage for ICESat-2 by measuring ice the satellite will fly over. > Operation IceBridge Antarctic 2014 Campaign Image Credit: NASA/Michael Studinger via NASA ift.tt/1tzK9rQ

NASA Shuttle Bus- April 30th, 2014- Wing Section.
We live right outside of NASA here in Houston, They retired the 747 used to ferry the Space Shuttles after their flights. They retired the Jumbo Bus and hauled it in pieces to its final resting spot at the Space Museum on the NASA Grounds. They had to move all the pieces at night and it came right by my neighborhood last night! What an event They had everything shut down! It as quite a sight. It was stopped here for 30 minutes while utility companies moved overhead wires at an upcoming intersection, making for a great photo-op!

This illustration depicts NASA's Mars 2020 rover on the surface of Mars. The mission, targeted for launch in July/August 2020, takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself. via NASA ift.tt/2q7Qktb
Taking part in the Oracles 2016 project in Walvis Bay, Namibia
ORACLES – Walvis Bay, 2016
Southern Africa produces almost a third of the Earth’s biomass burning (BB) aerosol particles, yet the fate of these particles and their influence on regional and global climate is poorly understood. ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) was a five year investigation with three Intensive Observation Periods (IOP) designed to study key processes that determine the climate impacts of African BB aerosols. Particles lofted into the mid-troposphere are transported westward over the SE Atlantic, home to one of the three permanent subtropical Stratocumulus (Sc) cloud decks in the world. The stratocumulus “climate radiators” are critical to the regional and global climate system.
During August to September 2016, NASA flew an ER-2 out of Walvis Bay with a series of imaging instruments along with a P-3, which conducted in situ observations over the South Atlantic and associated clouds. The single seater ER-2 flew across the Atlantic from Recife Brazil.

NASA's mission is to pioneer the future in space exploration, scientific discovery and aeronautics research. To do that, thousands of people have been working around the world -- and off of it -- for almost 50 years, trying to answer some basic questions. What's out there in space? How do we get there? What will we find? What can we learn there, or learn just by trying to get there, that will make life better here on Earth?
Cosmic dust clouds ripple across this infrared portrait of our Milky Way's satellite galaxy, the Large Magellanic Cloud. In fact, the remarkable composite image from the Herschel Space Observatory and the Spitzer Space Telescope show that dust clouds fill this neighboring dwarf galaxy, much like dust along the plane of the Milky Way itself. The dust temperatures tend to trace star forming activity. Spitzer data in blue hues indicate warm dust heated by young stars. Herschel's instruments contributed the image data shown in red and green, revealing dust emission from cooler and intermediate regions where star formation is just beginning or has stopped. Dominated by dust emission, the Large Magellanic Cloud's infrared appearance is different from views in optical images. But this galaxy's well-known Tarantula Nebula still stands out, easily seen here as the brightest region to the left of center. A mere 160,000 light-years distant, the Large Cloud of Magellan is about 30,000 light-years across. via NASA ift.tt/1SQ3gtN
Only in the fleeting darkness of a total solar eclipse is the light of the solar corona easily visible. Normally overwhelmed by the bright solar disk, the expansive corona, the sun's outer atmosphere, is an alluring sight. But the subtle details and extreme ranges in the corona's brightness, although discernible to the eye, are notoriously difficult to photograph. Pictured here, however, using over 120 images and meticulous digital processing, is a detailed wide-angle image of the Sun's corona taken during the Great American Eclipse in 2017 August. Clearly visible are intricate layers and glowing caustics of an ever changing mixture of hot gas and magnetic fields. Hundreds of stars as faint as 11th magnitude are visible behind the Moon and Sun, with Mars appearing in red on the far right. The next total eclipse of the Sun will occur on July 2 and be visible during sunset from a thin swath across Chile and Argentina. via NASA go.nasa.gov/2TnnUG4
Check this out from NASA -- What's being reflected in the world's largest mirror? Stars, galaxies, and a planet. Many of these stars are confined to the grand arch that runs across the image, an arch that is the central plane of our home Milky Way Galaxy. Inside the arch is another galaxy -- the neighboring Large Magellanic Cloud (LMC). Stars that are individually visible include Antares on the far left and Sirius on the far right. The planet Jupiter shines brightly just below Antares. The featured picture is composed of 15 vertical frames taken consecutively over ten minutes from the Uyuni Salt Flat in Bolivia. Uyuni Salt Flat (Salar de Uyuni) is the largest salt flat on Earth and is so large and so extraordinarily flat that, after a rain, it can become the world's largest mirror -- spanning 130 kilometers. This expansive mirror was captured in early April reflecting each of the galaxies, stars, and planet mentioned above. (ift.tt/2oTd3Ki)

Magnetic fields emerging from below the surface of the sun influence the solar wind—a stream of particles that blows continuously from the sun’s atmosphere through the solar system. Researchers at NASA and its university partners are using high-fidelity computer simulations to learn how these magnetic fields emerge, heat the sun’s outer atmosphere and produce sunspots and flares. This visualization shows magnetic field loops in a portion of the sun, with colors representing magnetic field strength from weak (blue) to strong (red). The simulation was run on the Pleiades supercomputer at the NASA Advanced Supercomputing facility at NASA's Ames Research Center in Moffett Field, California. The knowledge gained through simulation results like this one help researchers better understand the sun, its variations, and its interactions with Earth and the solar system.
