12.12.12 – Where No Musician Has Gone Before
Combining magnetic field data collected by NASA's Voyager 1 spacecraft with computer modeling techniques to reproduce the sounds of ancient musical instruments, Domenico Vicinanza and the ASTRA project created music played in the NASA booth at the international supercomputing conference (SC12) in November.
Visualization of a computational fluid dynamics (CFD) simulation of plume containment for the design of NASA's 21st Century Launch Complex
12.11.12 – Giving Rocket Science a Boost
As NASA pours both its brainpower and supercomputing power into the new Space Launch System, NASA Advanced Supercomputing modeling and simulation experts remind us that it really is rocket science.

12.05.12 – Revolutionizing Rotorcraft Design with CFD
NASA Advanced Supercomputing fundamental aeronautics researcher Neal Chaderjian is developing physics-based CFD tools to enhance the predictive accuracy of rotocraft flow fields.
Visualization of Arctic sea ice extent
11.21.12 – Ocean Currents Play a Role in Predicting Extent of Arctic Sea Ice
Combining models and observations, MIT researchers have discovered that feedback between sea ice and ocean improves Arctic ice extent forecast. Their model-observation synthesis employs NASA's Pleiades supercomputer.
Extreme dry conditions in North Africa illustrated by AIRS data map
11.08.12 - Climate Likely to Be on Hotter Side of Projections
A new NASA-funded study finds climate model projections that show a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise. The study included data from the Modern-Era Retrospective Analysis for Research and Applications (MERRA) run at the NASA Center for Climate Simulation.
Cross-section of Bolshoi simulation
10.01.12 - The Cosmological Supercomputer
The Bolshoi simulation evolves the universe all over again using 14,000 central processing units on NASA's Pleiades supercomputer.
Visualization of black holes merging
09.27.12 - Simulations Uncover 'Flashy' Secrets of Merging Black Holes
Einstein theorized that massive objects produce gravity distortions when they interact. Astronomers have so far found only indirect evidence of these disturbances, but some think that this discovery is just a few years away.
Visualization of global vegetation density
09.25.12 – NASA Earth Exchange: Meet Up in the NEX World
The NASA Earth Exchange (NEX) is a unique collaborative workspace where Earth scientists can join forces, make new discoveries, and share knowledge to gain a better understanding of our planet.

08.06.12 - In the Land of the Computer, Pleiades is King
NASA's flagship supercomputer, Pleiades, is the fourth most powerful system in the US. NBC Bay Area reporter Garvin Thomas goes backstage to get up-close-and-personal with Pleiades, which is critical to NASA scientists and engineers for missions on Earth and in space.
Visualization of hurricane in the Atlantic Ocean
07.31.12 - Simulated Nature Runs Its Course
A NASA Goddard climate model called GEOS-5 revisited the extraordinary 2005 Atlantic hurricane season as part of a gigantic two-year simulation run on Goddard’s Discover supercomputer.
Visualization of global aerosols: dust, sea salt, sulphate, and black and organic carbon
05.24.12 - Paint by Particle
NASA models and supercomputing have created a colorful new view of aerosol movement. The simulation took several weeks to process on a NASA Center for Climate Simulation supercomputer.
Screen capture from video on ocean currents showing the Gulf Stream in the Atlantic
04.09.12 - NASA Views Our Perpetual Ocean
Tens of thousands of ocean currents are captured in a new scientific visualization created by NASA's Goddard Space Flight Center from model-data syntheses made possible by high-end computing resources at NASA's Ames Research Center.

03.19.12 - Engineers Enlist Weather Model to Optimize Offshore Wind Plan
Using a sophisticated weather model, environmental engineers at Stanford University have defined optimal placement of a grid of four wind farms off the U.S. East Coast. The NASA Advanced Supercomputing (NAS) Division provided access to computational resources.
Artist's concept depicting the circumbinary planet called Kepler-16b (black circle) as it orbits a slowly rotating K-dwarf star and a small red dwarf star
03.06.12 – Searching for Sister Planets
With the help of one of NASA's largest space telescopes and its most powerful supercomputer, scientists are analyzing observational data gathered from the Kepler mission spacecraft to search the skies for Earth's sister planets.
Solar Dynamics Observatory (SDO) image of an X1.8 class solar flare
02.09.12 - Cracking the Mysteries of Space Weather
Our planet is mostly protected from solar flares, coronal mass ejections, and other space weather events by a cocoon of magnetic field called the magnetosphere. But sometimes Earth's magnetosphere "cracks" and lets space weather inside, where it can cause damage.
NASA's Terra satellite captured this true color image on February 7, 2010, showing part of the region affected by the Snowmageddon winter storms.
02.09.12 - Deconstructing a Mystery: What Caused Snowmaggedon?
Using a computer model that simulates the atmosphere, NASA scientists pieced together the meteorological whodunit of 2010's 'Snowmaggedon,' which entered the history books as the snowiest winter on record for the U.S. East Coast.
Still from the interactive charts
01.12.12 - NASA Study Shows Health, Food Security Benefits From Climate Change Actions
A new study led by a NASA Goddard Institute for Space Studies scientist highlights 14 key air pollution control measures that, if implemented, could slow the pace of global warming, improve health and boost agricultural production.
