            "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 || ",

            "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.

            "description": "On January 28, 2014, NASA's Interface Region Imaging Spectrograph, or IRIS, spacecraft saw its strongest solar flare since it launched in 2013. Solar flares are bursts of X-rays and light that stream out into space, but no one yet knows the fine details of what sets them off. By observing a layer of the sun’s lower atmosphere called the chromosphere, which helps regulate how energy and material flows up from the sun's surface, IRIS can see part of the process that powers these events. However, there's a bit of luck involved in making such observations. IRIS’s instruments can’t look at the entire sun at once, so scientists must decide what areas might be the most interesting to watch. On January 28, scientists focused IRIS’s telescope and imaging spectrograph on a magnetically active region on the sun. Perfect timing: They witnessed a medium-sized solar flare in the act of erupting. Watch the video to see the flare through IRIS's eyes. || ",

            "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. || ",

These layers make up what's called the interface region, an area where solar material is constantly writhing and exploding. The spacecraft is designed to take high-resolution images of the interface region in unprecedented detail. Such images will help scientists see how energy traveling through the region heats the sun's upper atmosphere to temperatures a thousand times hotter than the surface. Initial observations show the region is much more violent than previously understood, and contains a multitude of thin, fibril-like structures that have never before been seen.

Designed to research the interface region in more detail than has ever been done before, IRIS’s instrument is a combination of an ultraviolet telescope and a spectrograph. The telescope provides high-resolution images, capturing data on about 1 percent of the sun at a time. The images can resolve very fine features, as small as 150 miles across. While the telescope can look at only one wavelength of light at a time, the spectrograph collects information about many wavelengths of light at once. The instrument then splits the sun’s light into its various wavelengths and measures how much of any given wavelength is present. Analysis of the spectral lines can also provide velocity, temperature and density information, key information when trying to track how energy and heat moves through the region. || ",
