Comet C/2014 Q2 (Lovejoy) is one of more than 32 comets imaged by NASA's NEOWISE mission from December 2013 to December 2014. This image combines a series of observations made in November 2013, when Lovejoy was 1.7 astronomical units from the sun. The image spans half of one degree. It shows the comet moving in a mostly west and slightly south direction.

This 20X view of an enteric valve of patawatermes nigripunctatus, a humivore termite belonging to the Apicotermitinae subfamily, received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope.
This 20x photo of Urania ripheus (Madagascan Sunset Moth) received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. Mr. Laurie Knight of Maidstone, Kent, UK captured the moth with focus stacked, twin flash front illumination.
Projecting images on curved screens poses a dilemma. The sharper the image, the darker it is. A novel optical approach brings brightness and sharpness together for the first time on screens of any curvature — and additionally allows about 10,000-times faster projection rates. Researchers have applied a proven approach used with cameras.
NASA's Mars Exploration Rover Opportunity captured images of a comet passing much closer to Mars than any previous known comet flyby of Earth or Mars. The images of comet Siding Spring were taken against a backdrop of the pre-dawn Martian sky on October 19, 2014. Images of comet A1 Siding Spring from the rover's panoramic camera (Pancam) are online.
Through a computational algorithm, researchers have developed a neural network that allows a small robot to detect different patterns, such as images, fingerprints, handwriting, faces, bodies, voice frequencies and DNA sequences. Nancy Guadalupe Arana Daniel focused on the recognition of human silhouettes in disaster situations.
The subject of this Hubble image is NGC 5474, a dwarf galaxy located 21 million light-years away in the constellation of Ursa Major (The Great Bear). This beautiful image was taken with Hubble's Advanced Camera for Surveys (ACS). The term "dwarf galaxy" may sound diminutive, but don't let that fool you — NGC 5474 contains several billion stars!
Taking center stage in this new NASA/ESA Hubble Space Telescope image is a galaxy known as NGC 3081, set against an assortment of glittering galaxies in the distance. Located in the constellation of Hydra (The Sea Serpent), NGC 3081 is located over 86 million light-years from us. It is known as a type II Seyfert galaxy, characterized by its dazzling nucleus.
This gorgeous, high-arching double rainbow signaled the end to a stormy spring day. It was taken at sunset from Samos Island, Greece, a small island in the Aegean Sea. Reddened colors of the primary and secondary bows result from the increased path length of sunlight when the Sun is below the horizon.
This 50x photo of a crystal of sulphur, resorcinal and azelaic acid received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. The polarized light image was taken by Dr. John Hart of Hart3D Films and Deptartment of Atmospheric and Oceanic Science, Univ. of Colorado, Boulder.
Sandy landforms formed by the wind, or aeolian bedforms, are classified by the wavelength — or length — between crests. On Mars, we can observe four classes of bedforms (in order of increasing wavelengths): ripples, transverse aeolian ridges (known as TARs), dunes, and what are called “draa.” All of these are visible in this Juventae Chasma image.
In 43 hours across five science flights in late November 2013, NASA's P-3 research aircraft collected more than 20,000 kilometers (12,000 miles) worth of science data. Instruments gathered information about the thickness of the ice over subglacial lakes, mountains, coasts and frozen seas. The flights over Antarctica were part of Operation IceBridge, a multi-year mission to monitor conditions in Antarctica and the Arctic
Recently published research describes how archaeologists outfitted a customized drone with a heat-sensing camera to unearth what they believe are ceremonial pits and other features at the site of an ancient village in New Mexico. The discovery of the structures hidden beneath layers of sediment and sagebrush is being hailed as an important step that could help archaeologists shed light on mysteries long buried by eroding desert landscapes
The Grand Canyon in northern Arizona is a favorite for astronauts shooting photos from the International Space Station, as well as one of the best-known tourist attractions in the world. The steep walls of the Colorado River canyon and its many side canyons make an intricate landscape that contrasts with the dark green, forested plateau to the north and south.
Peering into the far reaches of the solar system, astronomers have spied a pink frozen world 7½ billion miles from the sun. It's the second such object to be discovered in a region of space beyond Pluto long considered a celestial wasteland.
This 50x image of a section of peacock feather won an honorable mention in the 2013 Nikon Small World Photomicrophotography Competition. The reflected light photograph was taken by Charles Krebs of Charles Krebs Photography in Issaquah, Wash.
Mars’ northern-most sand dunes are beginning to emerge from their winter cover of seasonal carbon dioxide (dry) ice. Dark, bare south-facing slopes are soaking up the warmth of the sun. The steep lee sides of the dunes are also ice-free along the crest, allowing sand to slide down the dune.
On August 3, 2004, NASA’s Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft began a seven-year journey, spiraling through the inner solar system to Mercury. One year after launch, the spacecraft zipped around Earth, getting an orbit correction from Earth’s gravity and getting a chance to test its instruments by observing its home planet.
An active region of the sun just rotating into the view of NASA's Solar Dynamics Observatory gives a profile view of coronal loops over about a two-day period, from February 8 to 10, 2014. Coronal loops are found around sunspots and in active regions.
Are we on the brink of a robotics revolution? That’s what numerous media outlets asked last December when Google acquired eight robotics companies that specialize in such innovations as manipulation, vision, and humanoid robots. Among those acquisitions was MIT spinout Meka Robotics. Founded in 2006, Meka was an early creator of “compliant” humanoid robots that now work safely alongside humans in everyday environments
Migratory birds and military aircraft often fly in a V-shaped formation. The “V” formation greatly boosts the efficiency and range of flying birds, because all except the first fly in the upward motion of air — called upwash — from the wingtip vortices of the bird ahead. In this image of a dune field on Mars ...
As NASA's Dawn spacecraft travels to its next destination, this mosaic synthesizes some of the best views the spacecraft had of the giant asteroid Vesta. Dawn studied Vesta from July 2011 to September 2012. The towering mountain at the south pole — more than twice the height of Mount Everest — is visible at the bottom of the image. The set of three craters known as the "snowman" can be seen at the top left.
This photograph of cloud bands over southern Mauritania was taken from the International Space Station with an oblique angle, such that the cloud shadows are a prominent part of the view. Beneath the clouds, the plateau of dark sedimentary rocks appears as a ragged, near-vertical escarpment
This mosaic of images from Curiosity's Mast Camera (Mastcam) shows geological members of the Yellowknife Bay formation. The scene has the Sheepbed mudstone in the foreground and rises up through Gillespie Lake member to the Point Lake outcrop.
On December 6, 1998, the crew of space shuttle mission STS-88 began construction of the International Space Station, attaching the U.S.-built Unity node and the Russian-built Zarya module together in orbit. The crew carried a large-format IMAX camera, used to take this image
The new HITS research group “Astroinformatics” will develop methods and software for astronomers and help facilitating the analysis and processing of the rapidly growing amount of data in astronomy. The junior group led by Kai Polsterer will work closely with other astronomical research groups in Heidelberg.
