            "title": "NASA's Many Views of a Massive CME",
            "description": "On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling between 1,800 and 2,200 miles per second as it left the sun. This was the fastest CME ever observed by STEREO.  Two other observatories – NASA's Solar Dynamics Observatory and the joint European Space Agency/NASA Solar and Heliospheric Observatory — witnessed the eruption as well. The July 2012 CME didn't move toward Earth, but watching an unusually strong CME like this gives scientists an opportunity to observe how these events originate and travel through space.  STEREO's unique viewpoint from the sides of the sun combined with the other two observatories watching from closer to Earth helped scientists create models of the entire July 2012 event. They learned that an earlier, smaller CME helped clear the path for the larger event, thus contributing to its unusual speed. Such data helps advance our understanding of what causes CMEs and improves modeling of similar CMEs that could be Earth-directed. || ",

            "description": "STEREO-A, at a position along Earth's orbit where it has an unobstructed view of the far side of the Sun, could clearly observe possibly the most powerful coronal mass ejection (CME) of solar cyle 24 on July 23, 2012.  The visualizations on this page cover the entire day.We see the flare erupt in the lower right quadrant of the solar disk from a large active region.  The material is launched into space in a direction towards STEREO-A.  This creates the ring-like 'halo' CME visible in the STEREO-A coronagraph, COR-2 (blue circular image).As the CME expands beyond the field of view of the COR-2 imager, the high energy particles reach STEREO-A, creating the snow-like noise in the image.  The particles also strike the HI-2 imager (blue square) brightening the image.The HI-1 imager has had 'bloom removal' enabled and filled with contents of the immediately previous HI-1 image, which creates a linear artifact above and below bright stars and planets. || ",

            "description": "On May 1, 2013, NASA's Solar Terrestrial Relations Observatory Ahead (STEREO-A) satellite along with its twin STEREO Behind (STEREO-B), observed an active region (right) of the sun erupt. This eruption, called a coronal mass ejection, or CME, sent plasma streaming out through the solar system. STEREO has an extreme ultraviolet camera similar to the Solar Dynamics Observatory (SDO) satellite, but it also has coronagraph telescopes like the European Space Agency/NASA Solar and Heliospheric Observatory (SOHO) where the bright sun is blocked by a disk so it does not overpower the fainter solar atmosphere. As a result, using its two inner coronagraphs, STEREO was able to track the CME from the solar surface out to 6.3 million miles. || ",

            "description": "On May 1, 2013, NASA's Solar Dynamics Observatory (SDO) watched as an active region just around the East limb (left edge) of the sun erupted with a huge cloud of solar material—a heated, charged gas called plasma. This eruption, called a coronal mass ejection, or CME, sent the plasma streaming out through the solar system. Viewing the sun in the extreme ultraviolet wavelength of 304 angstroms, SDO provided a beautiful view of the initial arc as it left the solar surface.  Such eruptions soon leave SDO's field of view, but other satellites in NASA's Heliophysics fleet can pick them up, tracking such space weather to determine if they are headed toward Earth or spacecraft near other planets. With advance warning, many space assets can be put into safe mode and protect themselves from the effects of such particle radiation.In addition to the images captured by SDO, the May 1, 2013 CME was also observed by the ESA/NASA Solar and Heliospheric Observatory (SOHO). SOHO houses two overlapping coronagraphs—telescopes where the bright sun is blocked by a disk so it doesn't overpower the fainter solar atmosphere—and they both saw the CME continue outward. The LASCO C2 coronagraph shows the region out to about 2.5 million miles. The LASCO C3 coronagraph expands even farther out to around 13.5 million miles. Both of these instruments show the CME as it expands and becomes fainter on its trip away from the sun.NASA's Solar Terrestrial Relations Observatory (STEREO) Ahead satellite saw the eruption from a very different angle. It, along with its twin STEREO Behind, is orbiting at a similar distance as Earth. STEREO-A orbits slightly faster than Earth and STEREO-B orbits slightly slower. Currently, STEREO-A is more than two-thirds of the way to being directly behind the sun, and has a view of the far side of the sun. From this perspective, the CME came off the right side of the sun. STEREO has an extreme ultraviolet camera similar to SDO's, but it also has coronagraphs like SOHO. As a result, using its two inner coronagraphs, it was able to track the CME from the solar surface out to 6.3 million miles.Working together, such missions provide excellent coverage of a wide variety of solar events, a wealth of scientific data—and lots of beautiful imagery.Watch this video on YouTube. || ",

            "description": "This visualization shows the original dataset from STEREO-A used to extract the motion of the coronal mass ejection (CME) in ID 3890. The data are combined from the SECCHI instrument, which includes an ultraviolet image of the Sun (EUVI), two coronographs (COR-1 & COR-2), and the wide-angle Heliospheric Imagers (HI-1 & HI-2).On this scale, the CME is so faint as to be invisible. However, the Heliospheric Imagers support such a broad range of image intensity that it is possible to observe the CME propagating through the field of view by computing differences of images with the preceeding image. This process is shown in animation #3890.The Earth (left side) and Venus (middle) are so bright as to 'bloom' along the readout line of the CCD (Charge-coupled device) pixels, which creates the bright vertical lines that move slightly with time. The dark shape on the left of the field of view is created by an occulting tab that was installed to (occasionally) hide the bright Earth in the view.The little cross markers label three other planets in the view of STEREO. Uranus is almost invisible in the scale of this imagery, but is visible in full-resolution datasets. || ",
