With the sun's powerful and potentially damaging rays eclipsed by Saturn itself, Cassini's onboard cameras were able to take advantage of this unique viewing geometry. They acquired a panoramic mosaic of the Saturn system that allows scientists to see details in the rings and throughout the system as they are backlit by the sun.With both Cassini's wide-angle and narrow-angle cameras aimed at Saturn, Cassini was able to capture 323 images in just over four hours. This final mosaic uses 141 of those wide-angle images.

Not to be confused with a solar flare, a CME is a solar phenomenon that can send solar particles into space and reach Earth one to three days later.Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and the ESA/NASA mission the Solar and Heliospheric Observatory, show that the CME left the sun at speeds of 275 miles per second. This is a fairly typical speed for CMEs, though much slower than the fastest ones, which can be almost ten times that speed.This visualization is constructed from a computer model run of the January 13, 2013 CME. The preliminary CME parameters were measured from instruments on the STEREO (the red and blue satellite icons) and SDO (in Earth orbit) satellites. The Enlil model was used to propagate those parameters through the solar system. From this model, they can estimate the strength and time of arrival of the CME at various locations around the solar system. This allows other missions to either safe-mode their satellites for protection, or allow them to conduct measurements to test the accuracy of the model.When Earth-directed, CMEs can cause a space weather phenomenon called a geomagnetic storm, which occurs when they successfully connect up with the outside of the Earth's magnetic envelope, the magnetosphere, for an extended period of time. In the past, CMEs of this speed have not caused substantial geomagnetic storms. They have caused auroras near the poles but are unlikely to affect electrical systems on Earth or interfere with GPS or satellite-based communications systems.Two active regions — named AR 11652 and AR 11654 by the National Oceanic and Atmospheric Administration (NOAA) — have produced four low-level M-class flares since Jan. 11. Solar flares are powerful bursts of light and radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however, when intense enough, they can disturb the atmosphere in the layer where GPS and communications signals travel. M-class flares are the weakest flares that can still cause some space weather effects near Earth. The recent flares caused weak radio blackouts and their effects have already subsided.NOAA's Space Weather Prediction Center is the United States Government official source for space weather forecasts. || ", "hits": 50 }, { "id": 4010, "url": "https://svs.gsfc.nasa.gov/4010/", "result_type": "Visualization", "release_date": "2012-12-20T09:00:00-05:00", "title": "Space Weather Research: The CME of March 2012", "description": "Forecasting space weather is of vital importance in protecting NASA assets around the solar system.

Such visualization techniques are needed for everything from making a map of planetary orbits based on nightly measurements of where they are in the sky to colorizing normally invisible light such as X-rays to produce \"images\" of the sun.More information, of course, requires more complex visualizations and occasionally such images are not just informative, but beautiful too.Such is the case with a new technique created by Nicholeen Viall, a solar scientist at NASA's Goddard Space Flight Center in Greenbelt, Md. She creates images of the sun reminiscent of Van Gogh, with broad strokes of bright color splashed across a yellow background. But it's science, not art. The color of each pixel contains a wealth of information about the 12-hour history of cooling and heating at that particular spot on the sun. That heat history holds clues to the mechanisms that drive the temperature and movements of the sun's atmosphere, or corona.To look at the corona from a fresh perspective, Viall created a new kind of picture, making use of the high resolution provided by NASA's Solar Dynamics Observatory (SDO). SDO's Atmospheric Imaging Assembly (AIA) provides images of the sun in 10 different wavelengths, each approximately corresponding to a single temperature of material. Therefore, when one looks at the wavelength of 171 angstroms, for example, one sees all the material in the sun's atmosphere that is a million degrees Kelvin. By looking at an area of the sun in different wavelengths, one can get a sense of how different swaths of material change temperature. If an area seems bright in a wavelength that shows a hotter temperature an hour before it becomes bright in a wavelength that shows a cooler temperature, one can gather information about how that region has changed over time.Viall's images show a wealth of reds, oranges, and yellow, meaning that over a 12-hour period the material appear to be cooling. Obviously there must have been heating in the process as well, since the corona isn't on a one-way temperature slide down to zero degrees. Any kind of steady heating throughout the corona would have shown up in Viall's images, so she concludes that the heating must be quick and impulsive — so fast that it doesn't show up in her images. This lends credence to those theories that say numerous nanobursts of energy help heat the corona. || ", "hits": 29 }, { "id": 20035, "url": "https://svs.gsfc.nasa.gov/20035/", "result_type": "Animation", "release_date": "2004-12-03T12:00:00-05:00", "title": "Coronal Mass Ejections Reach the Heliopause", "description": "Coronal mass ejections (CME) can propagate from the Sun to the boundary with interstellar space. || Movie of CME material reaching the heliopause. || Helio_pre.00002_print.jpg (1024x691) [67.5 KB] || Helio_pre.jpg (320x197) [7.2 KB] || Heliosphere_pre.jpg (320x238) [9.3 KB] || 1280x720_16x9_60p (1280x720) [0 Item(s)] || Helio.webmhd.webm (960x540) [4.2 MB] || HelioHD0200.mp4 (1280x720) [5.5 MB] || Helio.mpg (720x486) [3.2 MB] || Heliosphere.mpg (352x240) [3.2 MB] || ", "hits": 75 }, { "id": 2966, "url": "https://svs.gsfc.nasa.gov/2966/", "result_type": "Visualization", "release_date": "2004-07-21T12:00:00-04:00", "title": "Venus Transit from GOES/SXI", "description": "The planet Venus is seen passing between the Earth and the Sun in this sequence of images taken by GOES/SXI.
