            "title": "Light Echo",
            "description": "In 2002 a star named V838 Monocerotis let off a massive explosion, creating a strobe-like flash in the blackness of space. The light was so bright that for a brief time the star outshone every star in the Milky Way galaxy, including our sun. Over months, evidence of the outburst continued to make its way toward Earth, which lies about 20,000 light-years away. As light from the blast rippled outward, some of it reflected off of nearby clouds of interstellar dust producing a phenomenon known as a light echo. In a sequence of images taken in the aftermath of the explosion, a ring of dust appears at first glance to be growing around the star. But this movement is only an illusion—the result of reflected light taking different amounts of time to reach our planet. Watch the video for a view of this event as seen by the Hubble Space Telescope. || ",

            "description": "Not only does spring herald warmer days and blooming flowers, it also kicks off fireball season—a time of year when bright meteors appear in greater number than usual. Oftentimes fragments of asteroids and comets, meteors typically range in size from a few feet to smaller than a grain of sand. As these objects enter Earth's atmosphere, they break apart in fiery displays that last only seconds. In the weeks around the start of spring, the appearance rate of bright meteors, aka fireballs, can increase by as much as 30 percent. The reason why is still unknown, but one hypothesis is that more space debris litters this section of Earth's orbit. In search of the answer, NASA scientists set up a network of ground cameras that track and record video of meteors flaming overhead. The footage can be used to pinpoint a meteor's orbit and origin.

            "description": "The walls within some craters at the moon's poles have gone without sunlight for as long as two billion years. Known as permanently shadowed regions, these craters lie almost perpendicular to the sun, never receiving its warmth or light. By bouncing laser beams off the moon's surface, NASA's Lunar Reconnaissance Orbiter (LRO) mapped the shape and elevation of these incredibly dark areas. Detailed 3-D models constructed from the data, combined with data collected by other instruments aboard the spacecraft, reveal which craters are fully hidden from the sun's rays, and which crater floors are cold enough for chemicals such as water to build up in the lunar soil.

            "description": "Comet ISON could put on quite a show later this year. Come November this frozen body traveling from the outer reaches of the solar system will pass within 1.1 million miles of the sun's fiery surface. What happens next will either be a magnificent spectacle or a grand disappointment. If the comet survives its trip around the sun, dust and volatile gases liberated from its icy interior will intensify the glow of its bright halo and long tail—offering stargazers a visual feast. Alternatively, the sun's immense gravity could disintegrate the comet just as it would become most visible from Earth. Scientists think this is the comet's first journey through the inner solar system, so there's a good chance it could be loaded with material ready to be lit up by the sun's energy. Expectations are high that the comet could even be seen in daylight, possibly shining as bright as the moon. Watch the video to learn more. || ",

            "description": "On March 18, 2011, NASA's MESSENGER spacecraft entered orbit around Mercury, becoming the first spacecraft ever to do so. Among the many instruments on this pioneering probe is a wide-angle camera capable of generating high-resolution images of the planet's surface. By stitching thousands of these images together, scientists created the first complete map of Mercury. The result isn't just a pretty picture. The map's enhanced colors, produced by special filters fitted on the camera, tell a story about the chemical, mineralogical and geological history of the innermost planet in our solar system. Young craters, for example, appear light blue or white. Tan regions mark plains formed by lava flows. Dark blue represents areas rich in a dark mineral. Watch the visualization for a tour of this colorful new view of Mercury. || ",

            "description": "On February 15, 2013, an asteroid called 2012 DA14 raced through space a mere 17,200 miles from Earth's surface. Although the asteroid had no chance of hitting our planet, its approach was one of the closest ever recorded for a near-Earth object. Using one of NASA's Deep Space Network antennas, scientists created a series of radar images of the asteroid as it traveled away from Earth. These observations are essential for predicting its future trajectory. By analyzing the pixelated images scientists estimate the asteroid's length to be roughly 130 feet. On average, an object of that size crosses Earth's orbit at close range about once every 40 years. Watch the videos to see radar views of asteroid 2012 DA14 and a simulation of its near-Earth flyby. || ",

            "description": "Supernova remnant W49B is not your run-of-the-mill remains of an exploded star. In most cases when a star explodes, its cosmic guts scatter equally in all directions, forming a ring of material around the blast site. But W49B looks different. By combining X-ray images from NASA's Chandra X-ray Observatory, radio data from NSF's Very Large Array, and infrared images from Caltech's Palomar Observatory, scientists were able to create a detailed picture of the supernova remnant. By examining the image they found that not only did an unusual explosion produce W49B, giving it a barrel-shaped appearance, but it also lacked a neutron star at its center—a common feature of supernova remnants. Scientists think in place of the neutron star there may lie a black hole. If this is true, it means that W49B could harbor the youngest black hole ever detected in the Milky Way galaxy.

            "description": "Comet Pan-STARRS may soon be visible to the naked eye. Scientists predict this icy body will be observable in the night sky next month as it loops around the sun and passes within 100 million miles of our planet. The comet is thought to have come from a distant region of space, beyond Pluto, known as the Oort cloud. Back in Oort, it was just another hunk of floating cosmic debris—a frozen cocktail of volatile gases and stellar dust. But as the object neared the inner solar system, heat and energy from the sun transformed its anatomy, adding a long tail to its defunct shape. The best time to see Comet Pan-STARRS is in mid-March, when it will appear in the western sky just after sunset. Watch the video to learn more about this comet and its journey through space. || ",

            "description": "The Vela pulsar is a rapidly rotating neutron star located about 1,000 light-years from Earth in the Milky Way galaxy. A bright jet of charged particles and electromagnetic radiation, travelingat nearly three-quarters of the speed of light, shoots from its axis. In 2010, NASA's Chandra X-ray Observatory snapped a series of images over a period of four months that showed the pulsar's jet blasting material into space. Using these images, scientists modeled the jet's motion. To their surprise, the movement followed a winding path resembling that of a rotating helix. If their model is accurate, it means the pulsar may be off-balance, wobbling as it spins—a feature never before seen. Watch the video to see a time-lapse view of the pulsar as seen by the Chandra X-ray Observatory. || ",

The collisions marked the planned end to NASA's GRAIL (Gravity Recovery and Interior Laboratory) mission. Flying in formation, the twin, washing machine-sized probes, named Ebb and Flow, spent 351 days in lunar orbit mapping the moon's gravitational field. The maps revealed features of the lunar surface and interior in incredible detail, providing scientists with new information about the moon's craggy topography and lumpy crust. Using these maps, researchers will be able to peer back at the moon's early history and better understand its origin and development, along with that of Earth and the other rocky bodies in the solar system. The visualization shows the two spacecraft's final three orbits and their mission-ending crash. || ",

            "description": "Hard layers of ice make up the surface of Jupiter's frozen moon Europa. Glacial cracks and ridges scar its frigid white plains, carving paths across an icy shell that conceals a deep ocean of liquid water. Closer inspection of the moon's fractured topography reveals highly disrupted areas, called chaos terrains, where blocks of ice appear to have broken off, drifted and refrozen to the surface. Searching for an explanation of how these features formed, researchers studying images of Europa taken by NASA's Galileo spacecraft have come up with an answer. As plumes of warm ocean water rise to the subsurface, massive lakes develop inside the moon's crust—some larger than North America's Great Lakes combined. Over time, the ice directly above these lakes collapses, splintering into floating geometric fragments that rotate, raft and resettle into all kinds of chaotic configurations. Watch the video to learn more about Europa's chaos terrains. || ",
