In the early hours of November 27, 2013, Comet ISON entered the field of view of the European Space Agency/NASA Solar and Heliospheric Observatory. In this picture, called a coronagraph, the bright light of the sun itself is blocked so the structures around it are visible. The comet is seen in the lower right; a giant cloud of solar material, called a coronal mass ejection or CME, is seen billowing out under the sun.

This image of the Transantarctic Mountains was taken from the NASA P-3 airborne laboratory on November 27, 2013, near the end of the 2013 IceBridge Antarctic campaign. 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.
Three nanosatellites, known as Cubesats, are deployed from a Small Satellite Orbital Deployer (SSOD) attached to the Kibo laboratory’s robotic arm at 7:10 a.m. (EST) on November 19, 2013. Japan Aerospace Exploration Agency astronaut Koichi Wakata monitored the satellite deployment while operating the Japanese robotic arm from inside Kibo.
How far away is spiral galaxy NGC 4921? Although presently estimated to be about 310 million light years distant, a more precise determination could be coupled with its known recession speed to help humanity better calibrate the expansion rate of the entire visible universe.
High-resolution global atmospheric modeling provides a unique tool to study the role of weather within Earth’s climate system. NASA’s Goddard Earth Observing System Model (GEOS-5) is capable of simulating worldwide weather at resolutions as fine as 3.5 kilometers.
This image from the NASA/ESA Hubble Space Telescope captures an ongoing cosmic collision between two galaxies — a spiral galaxy is in the process of colliding with a lenticular galaxy. The image also reveals further evidence of the collision.
This 200x image of the down and belly feather from a yellow-bellied sapsucker was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. It was taken by James E. Hayden of The Wistar Institute Imaging Core Facility
Looking like an apparition rising from whitecaps of interstellar foam, the iconic Horsehead Nebula has graced astronomy books ever since its discovery more than a century ago. It is shadowy in optical light. It appears transparent and ethereal when seen at infrared wavelengths. The rich tapestry of the Horsehead Nebula pops out against the backdrop of Milky Way stars and distant galaxies that easily are visible in infrared light.
This 400x image of the trigeminal ganglion of a 2-day old zebrafish embryo was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. It was taken by Fengzhu Xiong of Harvard Medical School.
The Orbital Sciences Corporation Antares rocket, with the Cygnus cargo spacecraft aboard, is seen in this false color infrared image, as it launches from Pad-0A of the Mid-Atlantic Regional Spaceport (MARS), Wednesday, Sept. 18, 2013.
This 200x image of a mouse retina surface was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. The photo was taken by Dr. Alejandra Bosco and Monica L. Vetter of the University of Utah.
The Orion nebula is featured in this sweeping image from NASA's Wide-field Infrared Survey Explorer, or WISE. The constellation of Orion is prominent in the evening sky throughout the world from about December through April of each year.
The Soyuz TMA-11M rocket is launched with Expedition 38 Soyuz Commander Mikhail Tyurin of Roscosmos, Flight Engineer Rick Mastracchio of NASA and Flight Engineer Koichi Wakata of the Japan Aerospace Exploration Agency onboard, Thursday, November 7, 2013, at the Baikonur Cosmodrome in Kazakhstan
This 850x image of a live mouse gut organoid — fragments of gut tissue grown in vitro — shows cell nuclei in blue. It was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. The photo was taken while the tissue fragments were alive in order to study cell motility
Expedition 37 crew members aboard the International Space Station released Orbital Sciences' Cygnus spacecraft from the station's robotic arm at 7:31 a.m. EDT on October 22, 2013. Orbital Sciences engineers then conducted a series of planned burns and maneuvers to move Cygnus toward a destructive re-entry in Earth's atmosphere
This 350x image of the surface of a mouse colon was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. The nuclei, pseudocolored green, are stained with DAPI. Actin, colored red, is stained with rhodamine phalloidin.
The ring-like swirls of dust filling the Andromeda galaxy stand out colorfully in this new image from the Herschel Space Observatory, a European Space Agency mission with important NASA participation. The glow seen here comes from the longer-wavelength, or far, end of the infrared spectrum
This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on October 10, 2013. It was made by amateur image processor and Cassini fan Gordan Ugarkovic. This image has not been geometrically corrected
This 10x image of the chewing lice of a common buzzard (Colpocephalum platystomus) was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. It was taken by Györgyi Zséli of the Institute of Experimental Medicine
This photograph by an astronaut on the International Space Station highlights the snout of the Upsala Glacier (49.88°S, 73.3°W) on the Argentine side of the North Patagonian Icefield. Ice flow in this glacier comes from the north (right in this rotated image). Dark lines of rocky debris (moraine) within the ice give a sense of the slow ice flow from right to left.
Following a 50 km/h crash test, all that was left of the car was a heap of metal — one that contains valuable information on how vehicle safety could be improved. But the only way engineers can get at this information is if they can see inside the vehicle to analyze how its individual components reacted to the force of the impact.
This 400x image of Acineta tuberosa, a suctorian ciliate in the Phylum Ciliophora, was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. It was taken by Dr. Diana Lipscomb of George Washington University’s Department of Biological Sciences

This 25x image of a cardinal feather was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. It was taken by Ian Walker of Huddersfield, United Kingdom, using a brightfield technique.
A magnetic filament of solar material erupted on the sun in late September 2103, breaking the quiet conditions in a spectacular fashion. The 200,000-mile-long filament ripped through the sun's atmosphere, the corona, leaving behind what looks like a canyon of fire.
