            "description": "Symbols mark the locations of young, low-mass galaxies bursting with new stars when the universe was about 800 million years old. Using a filter sensitive to such galaxies, NASA’s James Webb Space Telescope imaged them with the help of a natural gravitational lens created by the massive galaxy cluster Abell 2744. In all, 83 young galaxies were found, but only the 20 shown here (white diamonds) were selected for deeper study. The inset zooms into one of the galaxies.

Two bright stars in our own galaxy display prominent six-spike diffraction patterns with bluish rays, visible at center left and lower left. Then 20 white diamonds sweep across the image. One diamond enlarges to reveal an image of a young, low-mass, star-forming galaxy. It looks like a green oval against a red and green checked background. The enlarged image then shrinks back, and the diamonds sweep away. The sequence loops. || Pandora_stamp_60pct.gif (600x600) [961.0 KB] || ",

            "description": "There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. Yet, despite decades of effort, no one knows what this \"dark matter\" really is. Many scientists think it's likely that the mystery will be solved with the discovery of new kinds of subatomic particles, types necessarily different from those composing atoms of the ordinary matter all around us. The search to detect and identify these particles is underway in experiments both around the globe and above it. Scientists working with data from NASA's Fermi Gamma-ray Space Telescope have looked for signals from some of these hypothetical particles by zeroing in on 10 small, faint galaxies that orbit our own. Although no signals have been detected, a novel analysis technique applied to two years of data from the observatory's Large Area Telescope (LAT) has essentially eliminated these particle candidates for the first time.WIMPs, or Weakly Interacting Massive Particles, represent a favored class of dark matter candidates. Some WIMPs may mutually annihilate when pairs of them interact, a process expected to produce gamma rays — the most energetic form of light — that the LAT is designed to detect. The team examined two years of LAT-detected gamma rays with energies in the range from 200 million to 100 billion electron volts (GeV) from 10 of the roughly two dozen dwarf galaxies known to orbit the Milky Way. Instead of analyzing the results for each galaxy separately, the scientists developed a statistical technique — they call it a \"joint likelihood analysis\" — that evaluates all of the galaxies at once without merging the data together. No gamma-ray signal consistent with the annihilations expected from four different types of commonly considered WIMP particles was found.For the first time, the results show that WIMP candidates within a specific range of masses and interaction rates cannot be dark matter. A paper detailing these results appeared in the Dec. 9, 2011, issue of Physical Review Letters. || ",

AVL used Amore software (http://avl.ncsa.illinois.edu/what-we-do/software) to interpolate and render 2700 frames (42 gigabytes of HD images). The simulation spans a time period of 13.7 billion years. This visualization provides insight into the assembly and formation of galaxies. James Webb Space Telescope (JWST) will probe the earliest periods of galaxy formation by looking deep into space to see the first galaxies that form in the universe, only a few hundred million years after the Big Bang.

The Advanced Visualization Laboratory (AVL) at the National Center for Supercomputing Applications (NCSA) collaborated with NASA and Drs. Renyue Cen and Jeremiah Ostriker to visualize a simulation of the nonlinear cosmological evolution of the universe.  Drs. Cen and Ostriker developed one of the largest cosmological hydrodynamic simulations and computed over 749 gigabytes of raw data at the NCSA in 2005. AVL used Amore software (http://avl.ncsa.illinois.edu/what-we-do/software) to interpolate and render approximately 322 gigabytes of a subset of the computed data. The simulation begins about 20 million years after the Big Bang - about 13.7 billion years ago - and extends until the present day.AVL(http://avl.ncsa.illinois.edu/) at NCSA (http://ncsa.illinois.edu/), University of Illinois (www.illinois.edu) || ",

            "description": "Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra. A new study led by Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Md., tracks this collective motion — dubbed the \"dark flow\" — to twice the distance originally reported, out to more than 2.5 billion light-years.  The study used a new technique to determine the motion of X-ray-emitting galaxy clusters. The clusters appear to be moving along a line extending from our solar system toward Centaurus/Hydra, but the direction of this motion is less certain. Evidence indicates that the clusters are headed outward along this path, away from Earth, but the team cannot yet rule out the opposite flow. The video shows the team's catalog of galaxy clusters separated into four \"slices\" representing different distance ranges. A colored ellipse shows the flow axis for the clusters within each slice. While the size and exact position of the ellipses vary, the overall trends show remarkable agreement. The video includes images of representative clusters in each distance slice. The dark flow is controversial because the distribution of matter in the observed universe cannot account for it. Its existence suggests that some structure beyond the visible universe — outside our \"horizon\" — is pulling on matter in our vicinity. || ",
