            "description": "In pursuit of understanding why the Sun's atmosphere is so much hotter than the surface, and to help differentiate between a host of theories about what causes this heating, researchers turn to NASA's Interface Region Imaging Spectrograph (IRIS) mission. IRIS was finely tuned with a high-resolution imager to zoom in on specific hard-to-see events on the Sun.A paper published in Nature on Sept. 21, 2020, reports on the first ever clear images of nanojets — bright, thin lights that travel perpendicular to magnetic structures in the solar atmosphere called the corona — in a process that reveals the existence of one of the potential coronal heating candidates: nanoflares. || ",

            "title": "Discovering the Sun’s Mysteriously Hot Atmosphere",
            "description": "Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface.Temperatures in the corona — the tenuous, outermost layer of the solar atmosphere — spike upwards of 2 million degrees Fahrenheit, while just 1,000 miles below, the underlying surface simmers at a balmy 10,000 F. How the Sun manages this feat remains one of the greatest unanswered questions in astrophysics; scientists call it the coronal heating problem. A new, landmark mission, NASA’s Parker Solar Probe — scheduled to launch no earlier than Aug. 11, 2018 — will fly through the corona itself, seeking clues to its behavior and offering the chance for scientists to solve this mystery.From Earth, as we see it in visible light, the Sun’s appearance — quiet, unchanging — belies the life and drama of our nearest star. Its turbulent surface is rocked by eruptions and intense bursts of radiation, which hurl solar material at incredible speeds to every corner of the solar system. This solar activity can trigger space weather events that have the potential to disrupt radio communications, harm satellites and astronauts, and at their most severe, interfere with power grids.Above the surface, the corona extends for millions of miles and roils with plasma, gases superheated so much that they separate into an electric flow of ions and free electrons. Eventually, it continues outward as the solar wind, a supersonic stream of plasma permeating the entire solar system. And so, it is that humans live well within the extended atmosphere of our Sun. To fully understand the corona and all its secrets is to understand not only the star that powers life on Earth, but also, the very space around us.Read more on NASA.gov. || ",

Then the camera moves around the Sun to match of with Earth again for the launch of Solar Orbiter in 2020.  After that, the camera moves in a slow drift around the Sun as the orbits evolve.  The Parker Solar Probe orbit fades out after the nominal end of mission in 2025.  This version has longer orbit trails to better view orbit changes, and the red along the orbits indicate the nominal science operations portions of the missions. || ParkerAndSolarOrbiter.InnerTourDeluxe.HAE.AU.clockSlate_EarthTarget.HD1080i.02000_print.jpg (1024x576) [100.7 KB] || DeluxeTour (1920x1080) [0 Item(s)] || ParkerAndSolarOrbiter.InnerTourDeluxe.HD1080i_p30.webm (1920x1080) [17.6 MB] || ParkerAndSolarOrbiter.InnerTourDeluxe.HD1080i_p30.mp4 (1920x1080) [179.8 MB] || DeluxeTour (3840x2160) [0 Item(s)] || ParkerAndSolarOrbiter.InnerTourDeluxe_2160p30.mp4 (3840x2160) [489.0 MB] || ParkerAndSolarOrbiter.InnerTourDeluxe.HD1080i_p30.mp4.hwshow [270 bytes] || ParkerAndSolarOrbiter.InnerTourDeluxe_2160p30.mp4.hwshow [211 bytes] || ",

            "title": "Scientists Uncover Origins of Dynamic Jets on Sun's Surface",
            "description": "At any given moment, as many as 10 million wild jets of solar material burst from the sun’s surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and despite their grass-like abundance, scientists didn’t understand how they form. Now, for the first time, a computer simulation — so detailed it took a full year to run — shows how spicules form, helping scientists understand how spicules can break free of the sun’s surface and surge upward so quickly. This work relied upon high-cadence observations from NASA’s Interface Region Imaging Spectrograph, or IRIS, and the Swedish 1-meter Solar Telescope in La Palma. Together, the spacecraft and telescope peer into the lower layers of the sun’s atmosphere, known as the interface region, where spicules form. The results of this NASA-funded study were published in Science on June 22, 2017 — a special time of the year for the IRIS mission, which celebrates its fourth anniversary in space on June 26.Research: On the generation of solar spicules and Alfvénic waves.Journal: Science, June 22, 2017.Link to paper: http://science.sciencemag.org/content/356/6344/1269.full || ",
