            "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 || ",

            "description": "A coronal mass ejection, or CME, surged off the side of the sun on May 9, 2014, and NASA's newest solar observatory caught it in extraordinary detail. This was the first CME observed by the Interface Region Imaging Spectrograph, or IRIS, which launched in June 2013 to peer into the lowest levels of the sun's atmosphere with better resolution than ever before. Watch the movie to see how a curtain of solar material erupts outward at speeds of 1.5 million miles per hour.IRIS must commit to pointing at certain areas of the sun at least a day in advance, so catching a CME in the act involves some educated guesses and a little bit of luck. \"We focus in on active regions to try to see a flare or a CME,\" said Bart De Pontieu, the IRIS science lead at Lockheed Martin Solar & Astrophysics Laboratory in Palo Alto, California. \"And then we wait and hope that we'll catch something. This is the first clear CME for IRIS so the team is very excited.\" The IRIS imagery focuses in on material of 30,000 Kelvin at the base, or foot points, of the CME. The line moving across the middle of the movie is the entrance slit for IRIS's spectrograph, an instrument that can split light into its many wavelengths – a technique that ultimately allows scientists to measure temperature, velocity and density of the solar material behind the slit. The field of view for this imagery is about five Earth's wide and about seven and a half Earth's tall. The IRIS Observatory was designed by and the mission is managed by Lockheed Martin Solar & Astrophysics Laboratory. NASA's Ames Research Center in Mountain View, California, provides mission operations and ground data systems.

On March 29, 2014, the Dunn Solar Telescope at Sacramento Peak, New Mexico was observing a solar active region and requested other observatories to watch as well.  As a result of this coordination, the region was being observed by a large number of different instruments, ground and space-based, when it subsequently erupted with an X-class flare.  This visualization presents various combinations of the datasets collected during this effort.  The color text represents the dominant color of the dataset in the imagery.Solar Dynamics Observatory (SDO): HMI (617.1nm).  This data represents the Sun is visible light similar to how we see it from the ground.Solar Dynamics Observatory (SDO): AIA (17.1nm).  Solar ultraviolet emission, which can only be seen from space, reveals plasma flowing, and escaping, along magnetic fields.IRIS Slit-Jaw Imager: 140.0nm.  This high-resolution imager also contains a slit (the dark vertical line in the center of the field) which directs the light to an ultraviolet spectrometer which is used to extract even more information about the light.  The imager slews back-and-forth across the region, providing spectra over a larger area of the Sun.Hinode/X-ray Telescope: x-ray band. Indicates very hot plasma.RHESSI: 50-100 keV.  High-energy gamma-ray emission.  Emission from these locations represent the very highest energy photons from the flare event.Dunn Solar Telescope: G-band filter.  This filter, showing much of the solar surface (photosphere) in visible light, provides a detailed view of the sunspots and convection cells.  The view moves because the instrument was repointed several times during the observation.Dunn Solar Telescope: IBIS ( Hydrogen alpha, 656.3nm;  Calcium 854.2 nm;  Iron 630.15nm).  This is the small rectangular view within the Dunn Solar Telescope G-band view.  This instrument can tune the wavelength during the observation, which provides views of the solar atmosphere at different depths. || ",

            "description": "The Slit-Jaw Imager (SJI) aboard IRIS (Interface Region Imaging Spectrograph) observes a tiny region of the Sun at an image resolution (0.166 arc-seconds per pixel) almost four times higher than the Solar Dynamics Observatory (SDO) (0.6 arc-seconds per pixel). In addition, IRIS has a narrow slit in the imaging plane (the thin, dark vertical line in the center of the inset) which directs some of the light to a spectrograph which allows solar physicists to determine velocity and temperature of the solar plasma.In this zoom-in from a full-disk view of the Sun from SDO, the imager is observering the Sun at a wavelength of 133nm (1330 angstroms). The imager field-of-view is moved across the solar disk in four steps, allowing the slit to pass over different regions of the Sun to determine the properties of the plasma.Note: IRIS and SDO are in very different orbits. You can see samples of the orbits at The 2013 Earth-Orbiting Heliophysics Fleet. IRIS is in a near-Earth orbit, while SDO is much higher at geosynchronous orbit. This difference in camera location creates a small parallax between the images composited from these two cameras. || ",

            "description": "On Jan. 28, 2014, NASA's Interface Region Imaging Spectrograph, or IRIS, witnessed its strongest solar flare since it launched in the summer of 2013. Solar flares are bursts of x-rays and light that stream out into space, but scientists don't yet know the fine details of what sets them off. IRIS peers into a layer of the sun's lower atmosphere just above the surface, called the chromosphere, with unprecedented resolution. However, IRIS can't look at the entire sun at the same time, so the team must always make decisions about what region might provide useful observations. On Jan. 28, scientists spotted a magnetically active region on the sun and focused IRIS on it to see how the solar material behaved under intense magnetic forces. At 2:40 p.m. EST, a moderate flare, labeled an M-class flare — which is the second strongest class flare after X-class – erupted from the area, sending light and x-rays into space. IRIS studies the layer of the sun’s atmosphere called the chromosphere that is key to regulating the flow of energy and material as they travel from the sun's surface out into space. Along the way, the energy heats up the upper atmosphere, the corona, and sometimes powers solar events such as this flare. IRIS is equipped with an instrument called a spectrograph that can separate out the light it sees into its individual wavelengths, which in turn correlates to material at different temperatures, velocities and densities. The spectrograph on IRIS was pointed right into the heart of this flare when it reached its peak, and so the data obtained can help determine how different temperatures of plasma flow where, giving scientists more insight into how flares work. || ",

            "description": "In late June 2013, the Interface Region Imaging Spectrograph, or IRIS, will launch from Vandenberg Air Force Base, Calif. IRIS will tease out the rules governing the lowest layers of the solar atmosphere — historically some of the hardest to untangle. Known as the solar interface region, this is one of the most complex areas in the sun's atmosphere: all the energy that drives solar activity travels through it. The interface region lies between the sun’s 6,000-degree, white-hot, visible surface, the photosphere, and the much hotter multi-million-degree upper corona. Interactions between the violently moving plasma and the sun’s magnetic field in this area may well be the source of the energy that heats the corona to its million-degree temperatures, some hundreds and occasionally thousands of times hotter than the sun's surface. The chromosphere is also considered a candidate as the origin for giant explosions on the sun such as solar flares and coronal mass ejections. IRIS will use high-resolution images, data and advanced computer models to unravel how solar gases move, gather energy and heat up through the lower solar atmosphere. Outfitted with state-of-the-art tools, IRIS will be able to tease apart what's happening in the solar interface region better than ever before. || ",

            "description": "Lying just above the sun's surface is an enigmatic region of the solar atmosphere called the interface region. A relatively thin region, just 3,000 to 6,000 miles thick, it pulses with movement: zones of different temperature and density are scattered throughout, while energy and heat course through the solar material. Understanding how the energy travels through this region – energy that helps heat the upper layer of the atmosphere, the corona, to temperatures of 1,000,000 kelvins, some thousand times hotter than the sun’s surface itself – is the goal of NASA's Interface Region Imaging Spectrograph, or IRIS, scheduled to launch on June 26, 2013 from California's Vandenberg Air Force Base. Scientists wish to understand the interface region in exquisite detail, since energy flowing through this region has an effect on so many aspects of near-Earth space. For one thing, despite the intense amount of energy deposited into the interface region, only a fraction leaksthrough, but this fraction drives the solar wind, the constant stream of particles that flows out to fill the entire solar system. The interface region is also the source of most of the sun's ultraviolet emission, which impacts both the near-Earth space environment and Earth's climate. IRIS's capabilities are uniquely tailored to unravel the interface region by providing both high-resolution images and a kind of data known as spectra, which can see many wavelengths at once. For its high-resolution images, IRIS will capture data on about one percent of the sun at a time. While these are relatively small snapshots, IRIS will be able to see very fine features, as small as 150 miles across. || ",

            "description": "Understanding the interface between the photosphere and corona remains a fundamental challenge in solar and heliospheric science. The Interface Region Imaging Spectrograph (IRIS) mission opens a window of discovery into this crucial region by tracing the flow of energy and plasma through the chromosphere and transition region into the corona using spectrometry and imaging. IRIS is designed to provide significant new information to increase our understanding of energy transport into the corona and solar wind and provide an archetype for all stellar atmospheres. The unique instrument capabilities, coupled with state of the art 3-D modeling, will fill a large gap in our knowledge of this dynamic region of the solar atmosphere. The mission will extend the scientific output of existing heliophysics spacecraft that follow the effects of energy release processes from the sun to Earth.IRIS will provide key insights into all these processes, and thereby advance our understanding of the solar drivers of space weather from the corona to the far heliosphere, by combining high-resolution imaging and spectroscopy for the entire chromosphere and adjacent regions. IRIS will resolve in space, time, and wavelength the dynamic geometry from the chromosphere to the low-temperature corona to shed much-needed light on the physics of this magnetic interface region. || ",
