Creativity is critical to making scientific breakthroughs, and art is often an expression (or product) of scientific knowledge. And both art and science begin in the experience of awe, of beholding something grand. The experience of a solar eclipse is a prime example of where these two human endeavors meet.Eclipses are celestial events we can predict with extreme precision, and their occurrence reveals fundamental truths about our place in the universe. Yet, as many eclipse watchers will attest, there is no anticipating how you will feel when experiencing one. The emotional resonance of eclipses is underlined by their presence in artforms in cultures across the world going back millennia.To celebrate the special role of eclipses in connecting art and science, creatives across NASA will be sharing their eclipse-inspired artwork in anticipation of two solar eclipses that will cross the United States on October 14, 2023, and April 8, 2024.The first two pieces in the series are presented below, with short biographies of their creators. || ", "hits": 86 }, { "id": 40502, "url": "http://svs.gsfc.nasa.gov/gallery/2024total-solar-eclipse-gallery/", "result_type": "Gallery", "release_date": "2023-10-31T00:00:00-04:00", "title": "2024 Total Solar Eclipse", "description": "On April 8, 2024, a total solar eclipse will cross North America, passing over Mexico, the United States, and Canada.

When one star in the sky appears to pass nearly in front of another, the light rays of the background source star become bent due to the warped space-time around the foreground star. This star is then a virtual magnifying glass, amplifying the brightness of the background source star, so we refer to the foreground star as the lens star. If the lens star harbors a planetary system, then those planets can also act as lenses, each one producing a short deviation in the brightness of the source. Thus we discover the presence of exoplanets, and measure its mass and separation from its star.

This is a subset of a longer, narrated animation that can be found here.The surface elevation1 and the bedrock topography2 are defined by geo-referenced DEM datasets. The change in elevation data3 derived from data collected by NASA’s ICESat satellite and from an airborne mission called Operation IceBridge is portrayed as colors accumulating over time on the surface. A cutting plane is used to reveal the thickness of the ice sheet and the bedrock topography beneath. A dataset of ice sheet velocity4 derived from from satellite interferometry is used to define the motion of the ice sheet over time. Ice flow movement is calculated from this velocity data, colored by the speed of the ice, and propagated over the surface of the ice sheet.This visualization was generated using Maya, Renderman and IDL. Over the years, we developed some tools to facilitate visualizing data. These include manifolds that accurately project data onto a sphere, routines to accurately access the correct data texture in a series based on the date keyframed in a Maya scene and a flow system that propagates flow vectors at any given time step and inserts the results directly into the RIB stream at render time. These tools are a credit to the director of our studio, Dr. Horace Mitchell and my colleague Greg Shirah.1.

Recent analysis of seven years of surface elevation readings from NASA's ICESat satellite and four years of laser and and ice-penetrating radar data from NASA's airborne mission Operation IceBridge shows us how the surface elevation of the ice sheet has changed.The colors shown on the surface of the ice sheet represent the accumulated change in elevation since 2003. The light yellow over the central region of the ice sheet indicates a slight thickening due to snow. This accumulation, along with the weight of the ice sheet, pushes ice toward the coast. Thinning near coastal regions, shown in green, blue and purple, has increased over time and now extends into the interior of the ice sheet where the bedrock topography permits. As a result, there has been an average loss of 300 cubic kilometers of ice per year between 2003 and 2012.This animation portrays the changes occurring in the surface elevation of the ice sheet since 2003 in three drainage regions: the southeast, the northeast and the Jakobshavn regions. In each region, the time advances to show the accumulated change in elevation from 2003 through 2012.—>
