They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and despite their grass-like abundance, scientists didn’t understand how they form. Now, for the first time, a computer simulation — so detailed it took a full year to run — shows how spicules form, helping scientists understand how spicules can break free of the sun’s surface and surge upward so quickly. This work relied upon high-cadence observations from NASA’s Interface Region Imaging Spectrograph, or IRIS, and the Swedish 1-meter Solar Telescope in La Palma. Together, the spacecraft and telescope peer into the lower layers of the sun’s atmosphere, known as the interface region, where spicules form.

It features a free-air gravity map of the Orientale impact basin based on data returned by the Gravity Recovery and Interior Laboratory (GRAIL) mission.Orientale is about 930 kilometers wide and lies on the western limb of the Moon as viewed from Earth. It's the Moon's youngest and best-preserved large impact basin, formed about 3.8 billion years ago at the end of the conjectured Late Heavy Bombardment. A paper in Science by Maria Zuber et al. uses the GRAIL data to shed new light on the basin's geology, while a second paper by Brandon Johnson et al. describes a computer simulation of the basin's formation constrained by that data.The shaded relief in this image is not a photograph. It's a very accurate computer rendering based on a digital model of the terrain. The model is derived from a digital elevation map called SLDEM2015. This map combines data from the laser altimeter (LOLA) on NASA's Lunar Reconnaissance Orbiter (LRO) with stereo imagery from the Terrain Camera on the Japan Space Agency's SELENE spacecraft.The angle of the virtual Sun was chosen to throw Orientale's terrain into high relief — it's just after sunrise at Orientale, about a day past full Moon. The camera is on the western terminator (day/night line) looking north.The colorful part is the gravity anomaly based on measurements by GRAIL. Red indicates areas of higher gravity, or excess mass, and blue indicates lower gravity or areas of mass deficits. The GRAIL data reveals the structure of the basin beneath the surface. The red in the center of the basin, for example, shows that the crust is particularly thin there, and that denser mantle material is closer to the surface. || ", "hits": 812 }, { "id": 4469, "url": "https://svs.gsfc.nasa.gov/4469/", "result_type": "Visualization", "release_date": "2016-06-16T15:00:00-04:00", "title": "Dynamic Earth-A New Beginning", "description": "The visualization 'Excerpt from \"Dynamic Earth\"' has been one of the most popular visualizations that the Scientific Visualization Studio has ever created. It's often used in presentations and Hyperwall shows to illustrate the connections between the Earth and the Sun, as well as the power of computer simulation in understanding those connections.There is one part of this visualization, however, that has always seemed a little clumsy to us. The opening shot is a pullback from the limb of the sun, where the sun is represented by a movie of 304 Angstrom images from the Solar Dynamics Observatory (SDO). It is difficult to pull back from the limb of a flat sun image and make the sun look spherical, and the problem was made more difficult because the original sun images were in a spherical dome show format. As a result, the pullback from the sun showed some odd reprojection artifacts.The best solution to this issue was to replace the existing pullout with a new one, one which pulled directly out from the center of the solar disk. For the new beginning, we chose a series of SDO images in the 171 Angstrom channel that show a visible coronal mass ejection (CME) in the lower right corner of the solar disk. Although this is not the specific CME that is seen affecting Venus and Earth later in this visualization, its presence links the SDO animation thematically to the later solar storm. The SDO images were also brightened considerably and tinted yellow to match the common perception of the Sun as a bright yellow object (even though it is actually white).Please go to the original version of this visualization to see the complete credits and additional details. || ", "hits": 63 }, { "id": 11922, "url": "https://svs.gsfc.nasa.gov/11922/", "result_type": "Produced Video", "release_date": "2015-10-20T11:00:00-04:00", "title": "Black Hole or Mega Star?", "description": "Scientists probe an exotic object in a distant galaxy. || c-1280.jpg (1280x720) [157.7 KB] || c-1024.jpg (1024x576) [118.3 KB] || c-1024_print.jpg (1024x576) [123.2 KB] || c-1024_searchweb.png (320x180) [40.4 KB] || c-1024_web.png (320x180) [40.4 KB] || c-1024_thm.png (80x40) [13.5 KB] || ", "hits": 55 }, { "id": 11894, "url": "https://svs.gsfc.nasa.gov/11894/", "result_type": "Produced Video", "release_date": "2015-06-23T14:00:00-04:00", "title": "Turning Black Holes into Dark Matter Labs", "description": "This video introduces a new computer simulation exploring the connection between two of the most elusive phenomena in the universe, black holes and dark matter.

By analyzing a supercomputer simulation of gas flowing into a black hole, the team finds they can reproduce a range of important X-ray features long observed in active black holes. Jeremy Schnittman, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md., led the research.Black holes are the densest objects known. Stellar black holes form when massive stars run out of fuel and collapse, crushing up to 20 times the sun's mass into compact objects less than 75 miles (120 kilometers) wide. Gas falling toward a black hole initially orbits around it and then accumulates into a flattened disk. The gas stored in this disk gradually spirals inward and becomes greatly compressed and heated as it nears the center, ultimately reaching temperatures up to 20 million degrees Fahrenheit (12 million C), or some 2,000 times hotter than the sun's surface. It glows brightly in low-energy, or soft, X-rays.For more than 40 years, however, observations show that black holes also produce considerable amounts of \"hard\" X-rays, light with energy tens to hundreds of times greater than soft X-rays. This higher-energy light implies the presence of correspondingly hotter gas, with temperatures reaching billions of degrees. The new study involves a detailed computer simulation that simultaneously tracked the fluid, electrical and magnetic properties of the gas while also taking into account Einstein's theory of relativity. Using this data, the scientists developed tools to track how X-rays were emitted, absorbed, and scattered in and around the disk. The study demonstrates for the first time a direct connection between magnetic turbulence in the disk, the formation of a billion-degree corona above and below the disk, and the production of hard X-rays around an actively \"feeding\" black hole.Watch this video on YouTube. || ", "hits": 143 }, { "id": 11269, "url": "https://svs.gsfc.nasa.gov/11269/", "result_type": "Produced Video", "release_date": "2013-06-06T00:00:00-04:00", "title": "Tracking A Superstorm", "description": "Hurricane Sandy pummeled the East Coast late in 2012’s Atlantic hurricane season, causing 159 deaths and $70 billion in damages. Days before landfall, forecasts of its trajectory were still being made. Some computer models showed that a trough in the jet stream would kick the monster storm away from land and out to sea. Among the earliest to predict its true course was NASA’s GEOS-5 global atmosphere model. The model works by dividing Earth’s atmosphere into a virtual grid of stacked boxes. A supercomputer then solves mathematical equations inside each box to create a weather forecast predicting Sandy’s structure, path and other traits. The NASA model not only produced an accurate track of Sandy, but also captured fine-scale details of the storm’s changing intensity and winds.

Two of these stars can be found in the intriguing binary system known as Cygnus OB2 #9. In 2011, NASA's Swift satellite, the European Space Agency's XMM-Newton observatory and several ground-based facilities took part in a campaign to monitor the system as the giant stars raced toward their closest approach. The observations are giving astronomers a more detailed picture of the stars, their orbits and the interaction of their stellar winds. An O-type star is so luminous that the pressure of its starlight actually drives material from its surface, creating particle outflows with speeds of several million miles an hour. Put two of these humongous stars in the same system and their winds can collide during all or part of the orbit, creating both radio emission and X-rays.In 2008, research showed that Cygnus OB2 #9 emitted radio signals that varied every 2.355 years.

Astronomers were lucky enough to find out as they watched this chance phenomenon, which happens about once every 100,000 years, unfold in a distant galaxy. First, the black hole's gravitational forces ripped the star apart, unleashing a stream of stellar fragments. Bits of ionized gas swirled around the black hole along elliptical paths, while other pieces of the star blasted into space. As the orbiting debris fell toward the black hole, colliding gas particles generated intense heat and light that could be seen from Earth. Astronomers looking through wide-field telescopes saw a bluish glow in the region of night sky where the galaxy is located. Instruments aboard NASA's Galaxy Evolution Explorer (GALEX) spacecraft also detected the increase in brightness, which lasted months.

These oppositely pointing magnetic fields are separated by a layer of current called the heliospheric current sheet. Due to the tilt of the magnetic axis in relation to the axis of rotation of the Sun, the heliospheric current sheet flaps like a flag in the wind. The flapping current sheet separates regions of oppositely pointing magnetic field, called sectors. As the solar wind speed decreases past the termination shock, the sectors squeeze together, bringing regions of opposite magnetic field closer to each other. The Voyager spacecraft have now found that when the separation of sectors becomes very small, the sectored magnetic field breaks up into a sea of nested \"magnetic bubbles\" in a phenomenon called magnetic reconnection. The region of nested bubbles is carried by the solar wind to the north and south filling out the entire front region of the heliopause and the sector region in the heliosheath.This discovery has prompted a complete revision of what the heliosheath region looks like. The smooth, streamlined look is gone, replaced with a bubbly, frothy outer layer.

During its nominal three-year mission, Aquarius will map the salinity at the ocean surface to improve our understanding of Earth's water cycle and ocean circulation. Aquarius will help scientists see how freshwater moves between the ocean and the atmosphere. It will monitor changes in the water cycle due to rainfall, evaporation, ice melting, and river runoff. Aquarius will also demonstrate a measurement capability that can be applied to future operational missions. Ocean circulation is driven in large part by changes in water density, which is determined by temperature and salinity. Cold, high-salinity water masses sink and trigger the ocean's \"themalhaline circulation\" - the surface and deep currents that distribute solar energy to regulate Earth's climate. By measuring salinity, Aquarius will provide new insight into this global process. Aquarius' measurements of ocean salinity will provide a new perspective on the ocean and its links to climate, greatly expanding upon limited past measurements. Aquarius salinity data - combined with data from other sensors that measure sea level, ocean color, temperature, winds and rainfall will give us a much clearer picture of how the ocean works, how it is linked to climate, and how it may respond to climate change.Aquarius will provide information that will help improve predictions of future climate trends and short-term climate events such as El Niño and La Niña.
