Visual Insights in Scientific Computing

The latest issue of Scientific Computing World has a nice 3-page article on Scientific Visualization, based on some classes and tutorials at recent events.  They start off with a typical SciVis pipeline (Kudos to them for actually including “postprocess” after Render, so many groups stop at Render), and discuss several commercial and freely available package […]

March 11, 2011 Honshu tsunami propagation video

The NOAA Center for Tsunami Research has released a video of the tsunami propagation in the Pacific Ocean. Propagation of the March 11, 2011 Honshu tsunami was computed with the NOAA forecast method using MOST model with the tsunami source inferred from DART® data. From the NOAA Center for Tsunami Research, located at NOAA PMEL […]

Baby Stars Form While Parent Star Sleeps

A star acquires much of its mass by accreting material from a disc. Accretion is probably not continuous but episodic. We have developed a method to include the effects of episodic accretion in simulations of star formation. Episodic accretion results in bursts of radiative feedback, during which a protostar is very luminous, and its surrounding […]

Ocean Crossroads

Phytoplankton are small organisms that live in both fresh and salt water, and many of them are single-celled plants. That makes them too small to be seen individually with the naked eye. However, when there are enough of them in the water, it can give the water a green color. Large enough concentrations can even […]


Scientific Visualization Image of 2010 Greenland Snow Melt

After experiencing their warmest year on record, many of the southern and western areas of Greenland also had the longest number of days that snow melted. The snow melt in 2010 lasted lasted 50 days longer than the 1979-2009 average snow melt normally does. In the image to the right, areas in orange and red […]

10 Stunning Science Visualizations

Both Wired and the NYTimes have small galleries up of the winning entries in the 2010 International Science & Engineering Visualization Challenge.  A bit heavy on the biological visualizations this year (several virus entries and such), the resulting pictures and videos truly are beautiful to behold. Gallery: 10 Stunning Science Visualizations | Wired Science | […]


Visualization at Supercomputing Centers

Wes Bethel (Lawrence Berkeley National Laboratory) , Kelly Gaither (TACC), Hank Childs (Lawrence Livermore National Laboratory), and Sean Ahern (Oak Ridge National Laboratory) are among the leaders today in the visualization community. They, along with John van Rosendale, Dale Southard, and Eric Brugger, have published a whitepaper titled: Visualization From the Skinny Guys at Big […]

Strong La Niña in December 2010

Earlier this year we told you that a La Niña event was starting to occur. A La Niña event is when the water is cool across the equatorial Pacific Ocean. An El Niño event is when the water is warm across the equatorial Pacific Ocean, and is the opposite of a La Niña. These two […]

Arctic Oscillation Chills US and Europe

Arctic Oscillation Chills US and Europe

Winter-like weather has arrived in the northern hemisphere. But is this winter colder than past ones, or warmer? That is the question NASA seeks to answer with this latest visualization. They have taken temperature measurements using the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. Then they compared the week of December 3-10, 2010 […]

Our Reliance on Plants is Increasing

NASA’s Image of the Day shows how our reliance on plants is increasing. From 1995 to 2005, human’s reliance on plants increased from 20.3 percent to 25.6 percent. This is due in part to population growth, as well as people using more plant products. This map shows the comparison for 2005. The colors represent the […]


Global Warming Mapped

NASA has recently released a new global map showing the temperature changes for the 2000-2009 decade. These maps do not show the absolute temperature, but instead show how much warmer or colder a region was on average than the 1951-1980 period. According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for […]

Sea Ice Yearly Minimum 1979-2010

The Scientific Visualization Studio at the NASA/Goddard Space Flight Center has recently released a video of the Arctic Sea Ice from 1979 to 2010. They are using microwave images from satellites to compute where the Arctic sea ice is located. In 2007, Arctic summer sea ice reached its lowest extent on record – nearly 25% […]
