It’s the first direct measurement of both sulfur’s gas and solid phases, a unique capability of X-ray spectroscopy, XRISM’s (pronounced “crism”) primary method of studying the cosmos.Using ultraviolet light, researchers have found gaseous sulfur in the space between stars. In denser parts of the interstellar medium, such as the molecular clouds where stars and planets are born, this form of sulfur quickly disappears.Scientists assume the sulfur condenses into a solid, either by combining with ice or mixing with other elements.When a doctor performs an X-ray here on Earth, they place the patient between an X-ray source and a detector. Bone and tissue absorb different amounts of the light as it travels through the patient's body, creating contrast in the detector.Scientists did something similar by picking a portion of the interstellar medium with the right density — not so thin that all the X-rays would pass through unchanged, but also not so dense that they would all be absorbed.Then they selected a bright X-ray source behind that section of the medium, a binary star system called GX 340+0 located over 35,000 light-years away in the southern constellation Scorpius.Using the Resolve instrument on XRISM, the researchers were able to measure the energy of GX 340+0’s X-rays and determined that sulfur was present not only as a gas, but also as a solid, possibly mixed with iron.Iron-sulfur compounds are often found in meteorites, so scientists have long thought they might be one way sulfur solidifies out of molecular clouds to travel through the universe. XRISM’s observations could match a few of these compounds — pyrrhotite, troilite, and pyrite, which is sometimes called fool’s gold.The researchers were also able to use measurements from a second X-ray binary called 4U 1630-472 that helped confirm their findings. || ", "hits": 104 }, { "id": 14869, "url": "https://svs.gsfc.nasa.gov/14869/", "result_type": "Produced Video", "release_date": "2025-07-18T11:00:00-04:00", "title": "STORIE Fit Test at NASA Goddard Space Flight Center", "description": "NASA’s STORIE mission, or Storm Time O+ Ring current Imaging Evolution, has completed its design, build, and testing campaign at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, ahead of its mission onboard the International Space Station (ISS).

It takes 16 days for the swaths to overlap enough to image the whole Earth.Previous Landsat sensors swept back and forth across the swath like a whisk broom to collect data. The sensor looked at a calibration source at the end of every row, which means that measurements were consistent from orbit to orbit. But this sensor design requires fast-moving parts, which are more likely to break.—and which did on Landsat 7.In contrast, the instruments on Landsat 8 view across the entire swath at once, building strips of data like a pushbroom. This approach requires no moving parts and gives the sensor detectors greater dwell time. The pushbroom instrument is smaller and lighter than previous whisk broom instruments, but its calibration is much more complex given the large number of detectors.“It was a natural step to evolve to a pushbroom sensor. The technology was proven on other satellites, and we knew we could get better accuracy. The pushbroom has no moving parts. It is a newer and more reliable technology.” explains Terry Arvidson, senior project engineer.For more information on the future of Landsat instruments, read https://landsat.gsfc.nasa.gov/landsat-9/instruments/. || ", "hits": 408 }, { "id": 12753, "url": "https://svs.gsfc.nasa.gov/12753/", "result_type": "Animation", "release_date": "2017-10-26T08:00:00-04:00", "title": "James Webb Space Telescope Laser-Focused Sight", "description": "After launch, NASA’s James Webb Space Telescope will use a process called wavefront sensing and control to perfect its vision in orbit.

The researchers suggest the comet swarm may be frozen debris trapped and concentrated by the gravity of an as-yet-unseen planet.Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, astronomers mapped millimeter-wavelength light from dust and carbon monoxide (CO) molecules in a disk surrounding the star. Located about 63 light-years away and only 20 million years old, Beta Pictoris hosts one of the closest, brightest and youngest debris disks known, making it an ideal laboratory for studying the early development of planetary systems. The ALMA images reveal a vast belt of carbon monoxide located at the fringes of the system. Much of the gas is concentrated in a single clump located about 8 billion miles (13 billion kilometers) from the star, or nearly three times the distance between the planet Neptune and the sun. The total amount of CO observed, the scientists say, exceeds 200 million billion tons, equivalent to about one-sixth the mass of Earth’s oceans.The presence of all this gas is a clue that something interesting is going on because ultraviolet starlight breaks up CO molecules in about 100 years, much faster than the main cloud can complete a single orbit around the star. Scientists calculate that a large comet must be completely destroyed every five minutes to offset the destruction of CO molecules. Only an unusually massive and compact swarm of comets could support such an astonishingly high collision rate.The researchers think these comet swarms formed when a as-yet-undetected planet migrated outward, sweeping icy bodies into resonant orbits. When the orbital periods of the comets matched the planet's in some simple ratio – say, two orbits for every three of the planet – the comets received a nudge from the planet at the same location each orbit. Like the regular push of a child's swing, these accelerations amplify over time and work to confine the comets in a small region. || ", "hits": 86 }, { "id": 11484, "url": "https://svs.gsfc.nasa.gov/11484/", "result_type": "Produced Video", "release_date": "2014-02-18T12:00:00-05:00", "title": "Engineering That Enables Science", "description": "A series of programs that define the spirit of engineering and showcase the unique capabilities within Goddard's Detector Systems Branch. || ", "hits": 13 }, { "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 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.

Along the way, some of these neutrons escape into space, where LEND can detect them.The presence of hydrogen in the lunar soil reduces the number of neutrons that escape. To map out likely deposits of water ice, LEND scientists look for this deficit of neutrons in the epithermal (medium) energy range.If the deficit were simply due to random fluctuations, the hydrogen map would never coalesce into a sharp image, but as this animation shows, the map of epithermal neutron deficit at the south pole of the Moon improves over time and converges on particular spots. These include especially strong signals in the permanently shadowed parts of Cabeus and Shoemaker craters, where ice would be completely shielded from the sun.

Since Fermi's launch in 2008, its Large Area Telescope (LAT) observes the entire sky in high-energy gamma rays every three hours, creating the most detailed map of the universe ever known at these energies. The total sum of starlight in the cosmos is known to astronomers as the extragalactic background light (EBL). To gamma rays, the EBL functions as a kind of cosmic fog. Ajello and his team investigated the EBL by studying gamma rays from 150 blazars, or galaxies powered by black holes, that were strongly detected at energies greater than 3 billion electron volts (GeV), or more than a billion times the energy of visible light. As matter falls toward a galaxy's supermassive black hole, some of it is accelerated outward at almost the speed of light in jets pointed in opposite directions. When one of the jets happens to be aimed in the direction of Earth, the galaxy appears especially bright and is classified as a blazar.Gamma rays produced in blazar jets travel across billions of light-years to Earth. During their journey, the gamma rays pass through an increasing fog of visible and ultraviolet light emitted by stars that formed throughout the history of the universe. Occasionally, a gamma ray collides with starlight and transforms into a pair of particles — an electron and its antimatter counterpart, a positron. Once this occurs, the gamma ray light is lost. In effect, the process dampens the gamma-ray signal in much the same way as fog dims a distant lighthouse. From studies of nearby blazars, scientists have determined how many gamma rays should be emitted at different energies. More distant blazars show fewer gamma rays at higher energies — especially above 25 GeV — thanks to absorption by the cosmic fog. The farthest blazars are missing most of their higher-energy gamma rays.The researchers then determined the average gamma-ray attenuation across three distance ranges between 9.6 billion years ago and today.

To account for the observations, the average stellar density in the cosmos is about 1.4 stars per 100 billion cubic light-years.

Eventually, one of the gamma rays encounters a photon of starlight and the gamma ray transforms into an electron and a positron. The remaining gamma-ray photons arrive at Fermi, interact with tungsten plates in the LAT, and produce the electrons and positrons whose paths through the detector allows astronomers to backtrack the gamma rays to their source. || ", "hits": 40 }, { "id": 11070, "url": "https://svs.gsfc.nasa.gov/11070/", "result_type": "Produced Video", "release_date": "2012-08-15T10:00:00-04:00", "title": "The QWIP Detector; an Infrared Instrument", "description": "All objects emit infrared radiation and the characteristics of the infrared radiation are primarily dependent on the temperature of the object.

The interstellar material has less oxygen in any given slice than anywhere in our solar system. This suggests that the solar system evolved in a separate, more oxygen-rich part of the galaxy or that critical, life-giving oxygen lies trapped in interstellar dust grains or ices.

Several layers of high-precision silicon detectors track the particles as they move through the instrument. The direction of the incoming gamma ray is determined by projecting the particle paths backward. The particles travel through the trackers until they reach a separate detector called a calorimeter, which absorbs and measures their energies.

As these powerful storms roll over Earth, their electric fields can eject a burst of gamma rays known as a terrestrial gamma-ray flash. And now scientists have discovered that these flashes also create the asymmetrical opposite of matter—antimatter. NASA's Fermi Gamma-ray Space Telescope was designed to monitor gamma rays, the highest-energy form of light, in outer space. But it also observes these flashes from thunderstorms. In 2009, Fermi detected gamma rays from a thunderstorm that was located well beyond the horizon from where it could directly observe the storm. So where did the rays come from? When antimatter collides with matter, the particles annihilate and emit gamma rays. This means the gamma rays detected by Fermi could only have come from an antimatter collision with the spacecraft itself, providing the first-ever clue that these Earth-bound storms can send antimatter into space.

LCROSS struck the floor of Cabeus crater, near the south pole of the moon, at 11:31 UT on October 9, 2009. LRO witnessed the impact from its orbit 50 kilometers (30 miles) above the surface.The purpose of the crash was to create a plume of debris that could be examined for the presence of water and other chemicals in the lunar regolith. LRO's early reconnaissance of the moon gave LCROSS mission planners valuable data in the months before LCROSS arrived, allowing them to choose an impact site with a high probability of producing interesting findings. LRO was also there for the event itself, using its array of instruments to gather data in the aftermath of the impact.This animation shows LRO and LCROSS from 5 minutes before to 5 minutes after the impact. Data gathered before the impact is represented by early results from LRO's Lunar Exploration Neutron Detector (LEND). LEND can sense hydrogen, and therefore possible water, in the lunar soil.
