The alignment of the telescope across all of Webb’s instruments can be seen in a series of images that captures the observatory’s full field of view. Featured in this video are engineering images demonstrating the sharp focus of each instrument. For this test, Webb pointed at part of the Large Magellanic Cloud, a small satellite galaxy of the Milky Way, providing a dense field of hundreds of thousands of stars across all the observatory’s sensors. The sizes and positions of the images shown depict the relative arrangement of each of Webb’s instruments in the telescope’s focal plane, each pointing at a slightly offset part of the sky relative to one another. Webb’s three imaging instruments are NIRCam (images shown here at a wavelength of 2 microns), NIRISS (image shown here at 1.5 microns), and MIRI (shown at 7.7 microns, a longer wavelength revealing emission from interstellar clouds as well as starlight). NIRSpec is a spectrograph rather than imager but can take images, such as the 1.1 micron image shown here, for calibrations and target acquisition. The dark regions visible in parts of the NIRSpec data are due to structures of its microshutter array, which has several hundred thousand controllable shutters that can be opened or shut to select which light is sent into the spectrograph. Lastly, Webb’s Fine Guidance Sensor tracks guide stars to point the observatory accurately and precisely; its two sensors are not generally used for scientific imaging but can take calibration images such as those shown here. This image data is used not just to assess image sharpness but also to precisely measure and calibrate subtle image distortions and alignments between the instrument sensors as part of Webb’s overall instrument calibration process. || ", "hits": 82 }, { "id": 14136, "url": "https://svs.gsfc.nasa.gov/14136/", "result_type": "Produced Video", "release_date": "2022-04-20T00:00:00-04:00", "title": "Webb Instrument Overview", "description": "A look at the instruments on the Webb Telescope. || Webb_Instruments-Thumbnail-2.jpg (1920x1080) [1.3 MB] || Webb_Instruments-Thumbnail-2_print.jpg (1024x576) [676.3 KB] || Webb_Instruments-Thumbnail-2_searchweb.png (320x180) [111.5 KB] || Webb_Instruments-Thumbnail-2_web.png (320x180) [111.5 KB] || Webb_Instruments-Thumbnail-2_thm.png (80x40) [13.8 KB] || WEBB_Instrument_Package-closecap.en_US.srt [4.9 KB] || WEBB_Instrument_Package.webm (4096x2160) [68.8 MB] || WEBB_Instrument_Package.mp4 (4096x2160) [276.0 MB] || ", "hits": 23 }, { "id": 14111, "url": "https://svs.gsfc.nasa.gov/14111/", "result_type": "Produced Video", "release_date": "2022-02-28T07:00:00-05:00", "title": "Webb's Mid-Infrared Instrument (MIRI) Light Path Animation", "description": "The spectrograph light path inside the Mid Infrared Instrument (MIRI) on the Webb Telescope.

However, in a process first observed by the MAVEN mission, some solar wind protons can slip past the bow shock by first bonding with electrons from the Mars upper atmosphere to form hydrogen atoms.

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 new observations show temperatures in the atmosphere so hot that only one current theory explains them: something called nanoflares – a constant peppering of impulsive bursts of heating, none of which can be individually detected — provide the mysterious extra heat. These new observations come from just six minutes worth of data from one of NASA's least expensive type of missions, a sounding rocket. The EUNIS mission, short for Extreme Ultraviolet Normal Incidence Spectrograph, launched on April 23, 2013, gathering a new snapshot of data every 1.3 seconds to track the properties of material over a wide range of temperatures in the complex solar atmosphere. The unique capabilities of EUNIS enabled researchers to obtain these results. The spectrograph was able to clearly and unambiguously distinguish the observations representing the extremely hot material – emission lines showing light with a wavelength of 592.6 angstrom, where an angstrom is the size of an atom — from a very nearby light wavelength of 592.2 angstroms. || ", "hits": 60 }, { "id": 11568, "url": "https://svs.gsfc.nasa.gov/11568/", "result_type": "Produced Video", "release_date": "2014-07-08T10:00:00-04:00", "title": "Eta Carinae's Homunculus Nebula Now in 3D", "description": "An international team of astronomers has developed a 3D model of a giant cloud ejected by the massive binary system Eta Carinae during its 19th century outburst. Eta Carinae lies about 7,500 light-years away in the southern constellation of Carina and is one of the most massive binary systems astronomers can study in detail. The smaller star is about 30 times the mass of the sun and may be as much as a million times more luminous. The primary star contains about 90 solar masses and emits 5 million times the sun's energy output. Both stars are fated to end their lives in spectacular supernova explosions.Between 1838 and 1845, Eta Carinae underwent a period of unusual variability during which it briefly outshone Canopus, normally the second-brightest star. As a part of this event, which astronomers call the Great Eruption, a gaseous shell containing at least 10 and perhaps as much as 40 times the sun's mass was shot into space. This material forms a twin-lobed dust-filled cloud known as the Homunculus Nebula, which is now about a light-year long and continues to expand at more than 1.3 million mph (2.1 million km/h). Using the European Southern Observatory's Very Large Telescope and its X-Shooter spectrograph, the team imaged near-infrared, visible and ultraviolet wavelengths along 92 separate swaths across the nebula, making the most complete spectral map to date. The researchers have used the spatial and velocity information provided by this data to create the first high-resolution 3D model of the Homunculus Nebula.The shape model was developed using only a single emission line of near-infrared light emitted by molecular hydrogen gas. The characteristic 2.12-micron light shifts in wavelength slightly depending on the speed and direction of the expanding gas, allowing the team to probe even dust-obscured portions of the Homunculus that face away from Earth. || ", "hits": 228 }, { "id": 11556, "url": "https://svs.gsfc.nasa.gov/11556/", "result_type": "Produced Video", "release_date": "2014-05-30T09:30:00-04:00", "title": "A First for NASA's IRIS: Observing a Gigantic Eruption of Solar Material", "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.

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.

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. || ", "hits": 31 }, { "id": 11448, "url": "https://svs.gsfc.nasa.gov/11448/", "result_type": "Produced Video", "release_date": "2014-02-06T00:00:00-05:00", "title": "Into The Fire", "description": "On June 27, 2013, NASA's Interface Region Imaging Spectrograph, or IRIS, launched into space to study the mysterious lowest layers of the sun’s atmosphere.

Telescopes can also collect light in ranges that our eyes alone cannot see, providing scientists ways of observing a whole host of material and processes that would otherwise be inaccessible. A new NASA movie of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, shows the wide range of wavelengths – invisible to the naked eye – that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors. As the colors sweep around the sun in the movie, viewers should note how different the same area of the sun appears. This happens because each wavelength of light represents solar material at specific temperatures. Different wavelengths convey information about different components of the sun's surface and atmosphere, so scientists use them to paint a full picture of our constantly changing and varying star.Yellow light of 5800 angstroms, for example, generally emanates from material of about 10,000 degrees F (5700 degrees C), which represents the surface of the sun. Extreme ultraviolet light of 94 angstroms, which is typically colorized in green in SDO images, comes from atoms that are about 11 million degrees F (6,300,000 degrees C) and is a good wavelength for looking at solar flares, which can reach such high temperatures. By examining pictures of the sun in a variety of wavelengths – as is done not only by SDO, but also by NASA's Interface Region Imaging Spectrograph, NASA's Solar Terrestrial Relations Observatory and the European Space Agency/NASA Solar and Heliospheric Observatory — scientists can track how particles and heat move through the sun's atmosphere. || ", "hits": 102 }, { "id": 4127, "url": "https://svs.gsfc.nasa.gov/4127/", "result_type": "Visualization", "release_date": "2013-12-16T12:00:00-05:00", "title": "The 2013 Earth-Orbiting Heliophysics Fleet", "description": "There've been a few changes since the 2012 Earth-Orbiting Heliophysics Fleet.

Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques. If we could travel to this giant planet, we would see a world still glowing from the heat of its formation with a color reminiscent of a dark cherry blossom, a dull magenta. GJ 504b orbits its star at nearly nine times the distance Jupiter orbits the sun, which poses a challenge to theoretical ideas of how giant planets form. According to the most widely accepted picture, called the core-accretion model, Jupiter-like planets get their start in the gas-rich debris disk that surrounds a young star. A core produced by collisions among asteroids and comets provides a seed, and when this core reaches sufficient mass, its gravitational pull rapidly attracts gas from the disk to form the planet. While this model works fine for planets out to where Neptune orbits, about 30 times Earth's average distance from the sun (30 astronomical units, or AU), it's more problematic for worlds located farther from their stars. GJ 504b lies at a projected distance of 43.5 AU from its star; the actual distance depends on how the system tips to our line of sight, which is not precisely known. The research is part of the Strategic Explorations of Exoplanets and Disks with Subaru (SEEDS), a project to directly image extrasolar planets and protoplanetary disks around several hundred nearby stars using the Subaru Telescope on Mauna Kea, Hawaii. The five-year project began in 2009 and is led by Motohide Tamura at the National Astronomical Observatory of Japan (NAOJ). While direct imaging is arguably the most important technique for observing planets around other stars, it is also the most challenging. The SEEDS project images at near-infrared wavelengths with the help of the telescope's novel adaptive optics system, which compensates for the smearing effects of Earth's atmosphere, and two instruments: the High Contrast Instrument for the Subaru Next Generation Adaptive Optics and the InfraRed Camera and Spectrograph. The combination allows the team to push the boundary of direct imaging toward fainter planets. GJ 504b is about four times more massive than Jupiter and has an effective temperature of about 460 degrees Fahrenheit (237 Celsius). It orbits the G0-type star GJ 504, which is slightly hotter than the sun and is faintly visible to the unaided eye in the constellation Virgo. The star lies 57 light-years away and the team estimates the system is about 160 million years old, based on methods that link the star's color and rotation period to its age. || ", "hits": 928 }, { "id": 11314, "url": "https://svs.gsfc.nasa.gov/11314/", "result_type": "Produced Video", "release_date": "2013-07-25T13:55:00-04:00", "title": "IRIS First Light", "description": "The images and video on this page are from the IRIS first light media teleconference on July 25, 2013.For supporting media resources, please click here.On July 17, 2013 at 11:14 pm PDT (2:14 pm EDT) the IRIS Lockheed Martin instrument team successfully opened the door on NASA’s Interface Region Imaging Spectrograph, which launched June 27, 2013, aboard a Pegasus XL rocket from Vandenberg Air Force Base, Calif.As the telescope door opened, IRIS’s single instrument began to observe the sun for the first time.

The planet circles its star at a distance of only 3 million miles, or about 30 times closer than Earth's distance from the sun, and completes an orbit every 2.2 days. Its star, named HD 189733A, is about 80 percent the size and mass of our sun.Astronomers classify the planet as a \"hot Jupiter.\" Previous Hubble observations show that the planet's deep atmosphere reaches a temperature of about 1,900 degrees Fahrenheit (1,030 C).HD 189733b periodically passes across, or transits, its parent star, and these events give astronomers an opportunity to probe its atmosphere and environment. In a previous study, a group led by Lecavelier des Etangs used Hubble to show that hydrogen gas was escaping from the planet's upper atmosphere. The finding made HD 189733b only the second-known \"evaporating\" exoplanet at the time.The system is just 63 light-years away, so close that its star can be seen with binoculars near the famous Dumbbell Nebula. This makes HD 189733b an ideal target for studying the processes that drive atmospheric escape.When HD 189733b transits its star, some of the star's light passes through the planet's atmosphere. This interaction imprints information on the composition and motion of the planet's atmosphere into the star's light.In April 2010, the researchers observed a single transit using Hubble's Space Telescope Imaging Spectrograph (STIS), but they detected no trace of the planet's atmosphere. Follow-up STIS observations in September 2011 showed a surprising reversal, with striking evidence that a plume of gas was streaming away from the exoplanet.The researchers determined that at least 1,000 tons of gas was leaving the planet's atmosphere every second. The hydrogen atoms were racing away at speeds greater than 300,000 mph. Because X-rays and extreme ultraviolet starlight heat the planet's atmosphere and likely drive its escape, the team also monitored the star with Swift's X-ray Telescope (XRT). On Sept. 7, 2011, just eight hours before Hubble was scheduled to observe the transit, Swift was monitoring the star when it unleashed a powerful flare. It brightened by 3.6 times in X-rays, a spike occurring atop emission levels that already were greater than the sun's. Astronomers estimate that HD 189733b encountered about 3 million times as many X-rays as Earth receives from a solar flare at the threshold of the X class. || ", "hits": 114 }, { "id": 40122, "url": "https://svs.gsfc.nasa.gov/gallery/mars/", "result_type": "Gallery", "release_date": "2012-06-28T00:00:00-04:00", "title": "Mars Missions and Science", "description": "This multimedia gallery assembles and organizes Mars content on the Scientific Visualization Studio website.
