Valentine's Day is special for NASA's Voyager mission. It was on February 14, 1990, that the Voyager 1 spacecraft looked back at our solar system and snapped the first-ever pictures of the planets from its perch at that time beyond Neptune. This "family portrait" captures Neptune, Uranus, Saturn, Jupiter, Earth and Venus from Voyager 1's unique vantage point.
This image from the Landsat-8 satellite acquired on September 23, 2014, brings us over the southwest United States: Nevada and Arizona. Las Vegas with its grid-like urban plan is visible near the center. Sitting in a basin of the Mojave Desert, the city is surrounded by a number of mountain ranges.
Galaxies can take many shapes and be oriented any way relative to us in the sky. This can make it hard to figure out their actual morphology, as a galaxy can look very different from different viewpoints. A special case is when we are lucky enough to observe a spiral galaxy directly from its edge, providing us with a spectacular view like this one.
NASA's Curiosity Mars rover can be seen at the "Pahrump Hills" area of Gale Crater in this view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. Pahrump Hills is an outcrop at the base of Mount Sharp. The region contains sedimentary rocks that scientists believe formed in the presence of water.
A snake-like robot designed to examine the inside of one of three melted reactors at the Fukushima Daiichi nuclear plant is ready to begin its expedition. Assessing the damage inside the reactors is a crucial step in the decommissioning of the plant, which was badly damaged by a 2011 earthquake and tsunami. Use of a remote-controlled robot is essential, because no humans can go close to the reactor chambers due to fatally high radiation.
New NASA/ESA Hubble Space Telescope images capture a rare occurrence, as three of Jupiter’s largest moons parade across the giant gas planet’s banded face. Hubble took a string of images of the event which show the three satellites — Europa, Callisto and Io — in action. The planet's four moons can commonly be seen transiting the face of Jupiter. However, seeing three of them transiting at the same time is rare.
NASA and NOAA have provided nighttime and daytime views of the Blizzard of 2015. A combination of the day-night band and high-resolution infrared imagery showed the historic blizzard near peak intensity as it moves over the New York through Boston Metropolitan areas at 1:45 a.m. EST on January 27, 2015. Nighttime lights of the region were blurred by high cloud tops associated with the most intense parts of the storm.
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.
Plans for the construction of the world's largest digital camera at the Department of Energy's SLAC National Accelerator Laboratory have reached a major milestone. The 3,200-megapixel centerpiece of the Large Synoptic Survey Telescope, which will provide unprecedented details of the universe and help address some of its biggest mysteries, has received key "Critical Decision 2" approval from the DOE.
In 2007, Google unleashed a fleet of cars with roof-mounted cameras to provide street-level images of roads around the world. Now, an MIT spinout is bringing similar drive-by innovations to energy efficiency by deploying cars with thermal-imaging rooftop rigs that create heat maps of thousands of homes and buildings per hour, detecting fixable leaks in building envelopes — windows, doors, walls and foundations — to help curb energy loss.
This Cassini image shows Jupiter from an unusual perspective. If you were to float just beneath the giant planet and look directly up, you would be greeted with this striking sight: red, bronze and white bands encircling a hazy south pole. The multicolored concentric layers are broken in places by prominent weather systems such as Jupiter’s famous Great Red Spot, visible towards the upper left, chaotic patches of cloud and pale white dots.
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.
