They surround themselves with minute calcium carbonate plates called “coccoliths,” which are highly reflective such that populations of these plants can be seen from space. Near the Patagonia Shelf, located east of Argentina and Uruguay, ocean waters thrive with high concentrations of microscopic phytoplankton—e.g., coccolithiphores, dinoflagellates, and diatoms to name a few. That is because in this region the warm, saline, southward-flowing Brazil Current flows past and mixes with the cool, less-saline, nutrient-rich northward-flowing Falklands/Malvinas Current, creating an ideal environment for biological productivity. Scientists use true color satellite images like these, taken by Aqua/MODIS from December 15, 2010 to February 15, 2011, to observe the recurring coccolithophore blooms in the Patagonia Shelf region and study the impacts of ocean acidification on these microscopic organisms. Imagery from these two months shows a coccolithophore bloom (turquoise) near the shelf break. The shelf's unique ecosystem supports important fisheries in the region, providing a favorable reproductive habitat for anchovies and sardines. || ", "hits": 44 }, { "id": 30512, "url": "https://svs.gsfc.nasa.gov/30512/", "result_type": "Hyperwall Visual", "release_date": "2014-06-02T00:00:00-04:00", "title": "Bright Waters of the Southern Ocean", "description": "Phytoplankton are microscopic organisms that live in watery environments, forming the foundation of the aquatic and marine food webs.

One can see shades of bright turquoise circling the Southern Ocean, a unique and consistent feature characterized by the presence of elevated PIC concentrations near the Sub-Tropical, Sub-Antarctic, and Polar Fronts. Referred to as the \"Great Calcite Belt,\" high PIC concentrations result from large numbers of highly reflective microscopic PIC plates called “coccoliths,” released from calcifying coccolithophores. Such regions of elevated reflectance have been observed each year during austral summer with minor variations from year to year. Many sectors of the Southern Ocean are generally characterized by low concentrations of potentially growth limiting iron (Fe) concentrations. Studies suggest, however, that coccolithophores are well adapted to growth under low ambient iron conditions. || ", "hits": 42 }, { "id": 11454, "url": "https://svs.gsfc.nasa.gov/11454/", "result_type": "Produced Video", "release_date": "2014-02-27T00:00:00-05:00", "title": "Green Survival", "description": "Through decades of human spaceflight, astronauts have found ways to adapt to life in space.

Since Fermi's launch in 2008, its Large Area Telescope (LAT) observes the entire sky in high-energy gamma rays every three hours, creating the most detailed map of the universe ever known at these energies. The total sum of starlight in the cosmos is known to astronomers as the extragalactic background light (EBL). To gamma rays, the EBL functions as a kind of cosmic fog. Ajello and his team investigated the EBL by studying gamma rays from 150 blazars, or galaxies powered by black holes, that were strongly detected at energies greater than 3 billion electron volts (GeV), or more than a billion times the energy of visible light. As matter falls toward a galaxy's supermassive black hole, some of it is accelerated outward at almost the speed of light in jets pointed in opposite directions. When one of the jets happens to be aimed in the direction of Earth, the galaxy appears especially bright and is classified as a blazar.Gamma rays produced in blazar jets travel across billions of light-years to Earth. During their journey, the gamma rays pass through an increasing fog of visible and ultraviolet light emitted by stars that formed throughout the history of the universe. Occasionally, a gamma ray collides with starlight and transforms into a pair of particles — an electron and its antimatter counterpart, a positron. Once this occurs, the gamma ray light is lost. In effect, the process dampens the gamma-ray signal in much the same way as fog dims a distant lighthouse. From studies of nearby blazars, scientists have determined how many gamma rays should be emitted at different energies. More distant blazars show fewer gamma rays at higher energies — especially above 25 GeV — thanks to absorption by the cosmic fog. The farthest blazars are missing most of their higher-energy gamma rays.The researchers then determined the average gamma-ray attenuation across three distance ranges between 9.6 billion years ago and today. From this measurement, the scientists were able to estimate the fog's thickness. To account for the observations, the average stellar density in the cosmos is about 1.4 stars per 100 billion cubic light-years. To put this in another way, the average distance between stars in the universe is about 4,150 light-years.See the media briefing page here. || ", "hits": 196 }, { "id": 11130, "url": "https://svs.gsfc.nasa.gov/11130/", "result_type": "Produced Video", "release_date": "2012-11-01T14:00:00-04:00", "title": "Fermi Observation of Early Background Light Animation", "description": "This animation tracks several gamma rays through space and time, from their emission in the jet of a distant blazar to their arrival in Fermi's Large Area Telescope (LAT).

Eventually, one of the gamma rays encounters a photon of starlight and the gamma ray transforms into an electron and a positron. The remaining gamma-ray photons arrive at Fermi, interact with tungsten plates in the LAT, and produce the electrons and positrons whose paths through the detector allows astronomers to backtrack the gamma rays to their source. || ", "hits": 84 }, { "id": 11031, "url": "https://svs.gsfc.nasa.gov/11031/", "result_type": "Produced Video", "release_date": "2012-07-05T07:00:00-04:00", "title": "Space Geodesy Profiles", "description": "Scientists from NASA's Space Geodesy Project discuss the techniques they use to precisely measure the Earth's position in the universe, determine the Earth's center of mass, calibrate satellites, observe sea level rise, and track the movements of the tectonic plates. || ", "hits": 35 }, { "id": 10595, "url": "https://svs.gsfc.nasa.gov/10595/", "result_type": "Produced Video", "release_date": "2010-06-23T00:00:00-04:00", "title": "Ten Cool Things Seen in the First Year of LRO", "description": "Having officially reached lunar orbit on June 23nd, 2009, the Lunar Reconnaissance Orbiter (LRO) has now marked one full year on its mission to scout the moon.
