NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet's known moons. Images taken with Cassini's narrow angle camera on April 15, 2013 show disturbances at the very edge of Saturn's A ring the outermost of the planet's large, bright rings.
A United Launch Alliance Atlas V rocket with NASA's Tracking and Data Relay Satellite (TDRS-L) spacecraft on board arrives at the launch pad at Cape Canaveral Air Force Station's Launch Complex 41. The TDRS-L spacecraft is the second of three new satellites designed to ensure vital operational continuity for NASA by expanding the lifespan of the Tracking and Data Relay Satellite System (TDRSS) fleet
An embryo sac of mature thale cress, a small flowering plant native to Eurasia, showing the central cell F-actin, the egg cell nucleus and the synergid cells. This 60x image received an honorable mention in the 2013 Nikon Small World Photomicrophotography Competition. It was taken by Dr. Tomokazu Kawashima, of Temasek Life Sciences Laboratory in Singapore, using confocal microscopy and image stacking.
Living harvestmen — a group of arachnids more commonly known as daddy longlegs — have a single pair of eyes that help them navigate habitats in every continent except Antarctica. But a newly described 305-million-year-old fossil found in eastern France shows that wasn’t always the case.
This esthetic close-up of cosmic clouds and stellar winds features LL Orionis, interacting with the Orion Nebula flow. Adrift in Orion's stellar nursery and still in its formative years, variable star LL Orionis produces a wind more energetic than the wind from our own middle-aged Sun.
Suppose you’re trying to navigate an unfamiliar section of a big city, and you’re using a particular cluster of skyscrapers as a reference point. Traffic and one-way streets force you to take some odd turns and, for a while, you lose sight of your landmarks. When they reappear, in order to use them for navigation, you have to be able to identify them as the same buildings you were tracking before — as well as your orientation...
NASA has made available to the public, at no cost, more than 1,000 codes with its release on April 10, 2014, of a new online software catalog. Organized into 15 broad categories, the new catalog offers a wide variety of applications for use by industry, academia, other government agencies and the general public.
NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and found it definitely lives up to its nickname — El Gordo (Spanish for "the fat one"). By measuring how much the cluster's gravity warps images of galaxies in the distant background, a team of astronomers has calculated the cluster's mass to be as much as 3 million billion times the mass of our sun.
This 100x image shows detail of the microtubules and nucleus in a COS-7 old world monkey kidney, SV40 transformed cultured cell. It received an honorable mention in the 2013 Nikon Small World Photomicrophotography Competition and was taken by Dr. Mariela Loschi of Buenos Aires, Argentina, using confocal microscopy.
This view of the frozen fjord downstream of Violingletscher (Violin Glacier) in Østgrønland (East Greenland) was seen during an Operation IceBridge survey flight on April 5, 2014. NASA’s Operation IceBridge images Earth's polar ice in unprecedented detail to better understand processes that connect the polar regions with the global climate system. IceBridge utilizes a highly specialized fleet of research aircraft and ...
This 5x image of the egg sack of a pirate spider (Ero sp.) received an honorable mention in the 2013 Nikon Small World Photomicrophotography Competition. It was taken by Geir Drange of Asker, Norway using reflected light and focus stacking.
At Cape Canaveral Air Force Station's Space Launch Complex 41 a United Launch Alliance Atlas V rocket stands ready to boost the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft on a 10-month journey to the Red Planet. MAVEN is atop a United Launch Alliance Atlas V rocket. Positioned in an orbit above the Red Planet, MAVEN will study the upper atmosphere of Mars in unprecedented detail.
A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists have developed new maps showing that the galactic center produces more high-energy gamma rays than can be explained by known sources
This 200x image of the radula (rasping organ) of the mollusc Buccinum undatum (common whelk) received an honorable mention in the 2013 Nikon Small World Photomicrophotography Competition. It was taken by Dr. David Maitland of Feltwell, Norfolk, UK, using differential interference contrast.
In celebration of the 24th anniversary of the launch of NASA's Hubble Space Telescope, astronomers captured infrared-light images of a churning region of star birth 6,400 light-years away. This colorful Hubble Space Telescope mosaic of a small portion of the Monkey Head Nebula unveils a collection of carved knots of gas and dust silhouetted against glowing gas.
Flowering plants attract pollinating insects with scent from their flowers and bright colors. If they have become infested with herbivores like caterpillars, they attract beneficial insects like parasitic wasps with the help of scent signals from their leaves. The wasps then lay their eggs in the caterpillars and kill the parasites.
NASA and the Japan Aerospace Exploration Agency (JAXA) have released the first images captured by their newest Earth-observing satellite, the Global Precipitation Measurement (GPM) Core Observatory, which launched into space February 27, 2014.
A powerful storm passed over New Zealand’s South Island in March 2014 and brought gale-force winds, torrential rains, and flooding to the city of Christchurch. A total of 74 millimeters (three inches) of rain fell on March 4 to 5, according to MetService, New Zealand’s national meteorological service. More than 100 homes flooded and more than 4,000 lost power around the country’s third most populous city.
Providing a rare glimpse of the trade secrets of planetary scientists, the journal Icarus published a study this month that compared lunar crater counts by eight professionals with crowdsourced counts by volunteers.
At about 89,000 miles in diameter, Jupiter could swallow 1,000 Earths. It is the largest planet in the solar system and perhaps the most majestic. Vibrant bands of clouds carried by winds that can exceed 400 mph continuously circle the planet's atmosphere.
In 2007, MIT scientists developed a type of microscopy that allowed them to detail the interior of a living cell in three dimensions, without adding any fluorescent markers or other labels. This technique also revealed key properties, such as the cells’ density.
This still image was taken from a new NASA movie of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, showing the wide range of wavelengths — invisible to the naked eye — that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors.
This 40x image of pyramidal neurons and their dendrites visualized in the visual cortex of a mouse brain won 17th place in the 2013 Nikon Small World Photomicrophotography Competition. It was taken by Dr. Alexandre William Moreau of the Institute of Neurology, University College London.
