Lighter colors indicate brighter gamma-ray sources. The map is centered on the center of our galaxy. The most prominent feature is the bright, diffuse glow running along the middle of the map, which marks the central plane of our Milky Way galaxy. The gamma rays there are mostly produced when energetic particles accelerated in the shock waves of supernova remnants collide with gas atoms and even light between the stars. Many of the star-like features above and below the Milky Way plane are distant galaxies powered by supermassive black holes. Many of the bright sources along the plane are pulsars. The image was constructed from 15 years of observations using front-converting gamma rays with energies greater than 1 GeV.

The X-ray burst, the brightest seen by NICER so far, came from an object named SAX J1808.4-3658, or J1808 for short. The observations reveal many phenomena that have never been seen together in a single burst. In addition, the subsiding fireball briefly brightened again for reasons astronomers cannot yet explain. The data reveal a two-step change in brightness, which scientists think is caused by the ejection of separate layers from the pulsar surface, and other features that will help them decode the physics of these powerful events.The explosion, which astronomers classify as a Type I X-ray burst, released as much energy in 20 seconds as the Sun does in nearly 10 days.J1808 is located about 11,000 light-years away in the constellation Sagittarius, spins at a dizzying 401 rotations each second, and is one member of a binary system. Its companion is a brown dwarf, an object larger than a giant planet yet too small to be a star. A steady stream of hydrogen gas flows from the companion toward the neutron star, and it accumulates in a vast storage structure called an accretion disk.Hydrogen raining onto the pulsar's surface forms a hot, ever-deepening global “sea.” At the base of this layer, temperatures and pressures increase until hydrogen nuclei fuse to form helium nuclei, which produces energy — a process at work in the core of our Sun. The helium settles out and builds up a layer of its own. Eventually, the conditions allow helium nuclei to fuse into carbon. The helium erupts explosively and unleashes a thermonuclear fireball across the entire pulsar surface.As the burst started, NICER data show that its X-ray brightness leveled off for almost a second before increasing again at a slower pace. The researchers interpret this “stall” as the moment when the energy of the blast built up enough to blow the pulsar’s hydrogen layer into space. The fireball continued to build for another two seconds and then reached its peak, blowing off the more massive helium layer. The helium expanded faster, overtook the hydrogen layer before it could dissipate, and then slowed, stopped and settled back down onto the pulsar’s surface. Following this phase, the pulsar briefly brightened again by roughly 20 percent for reasons the team does not yet understand. || ", "hits": 92 }, { "id": 13415, "url": "https://svs.gsfc.nasa.gov/13415/", "result_type": "Produced Video", "release_date": "2019-10-31T00:00:00-04:00", "title": "NASA Science Live: Galaxy of Horrors (Episode 10)", "description": "NASA Science Live: Galaxy of Horrors (Episode 10) || 13415_NSL_Galaxy_Ep10_youtube_720.00001_print.jpg (1024x576) [79.7 KB] || 13415_NSL_Galaxy_Ep10_youtube_720.00001_searchweb.png (320x180) [79.6 KB] || 13415_NSL_Galaxy_Ep10_youtube_720.00001_thm.png (80x40) [5.5 KB] || 13415_NSL_Galaxy_Ep10_lowres.mp4 (1280x720) [550.9 MB] || 13415_NSL_Galaxy_Ep10_youtube_720.mp4 (1280x720) [3.1 GB] || 13415_NSL_Galaxy_Ep10.mov (1280x720) [20.7 GB] || 13415_NSL_Galaxy_Ep10_youtube_720.webm (1280x720) [222.1 MB] || 13415_NSL_Galaxy_Ep10.en_US.srt [59.1 KB] || 13415_NSL_Galaxy_Ep10.en_US.vtt [55.9 KB] || ", "hits": 44 }, { "id": 13326, "url": "https://svs.gsfc.nasa.gov/13326/", "result_type": "Produced Video", "release_date": "2019-09-25T13:00:00-04:00", "title": "Black Hole Accretion Disk Visualization", "description": "This movie shows a complete revolution around a simulated black hole and its accretion disk following a path that is perpendicular to the disk. The black hole’s extreme gravitational field redirects and distorts light coming from different parts of the disk, but exactly what we see depends on our viewing angle. The greatest distortion occurs when viewing the system nearly edgewise. As our viewpoint rotates around the black hole, we see different parts of the fast-moving gas in the accretion disk moving directly toward us. Due to a phenomenon called \"relativistic Doppler beaming,\" gas in the disk that's moving toward us makes that side of the disk appear brighter, the opposite side darker. This effect disappears when we're directly above or below the disk because, from that angle, none of the gas is moving directly toward us.When our viewpoint passes beneath the disk, it looks like the gas is moving in the opposite direction. This is no different that viewing a clock from behind, which would make it look like the hands are moving counter-clockwise.CORRECTION: In earlier versions of the 360-degree movies on this page, these important effects were not apparent. This was due to a minor mistake in orienting the camera relative to the disk. The fact that it was not initially discovered by the NASA scientist who made the movie reflects just how bizarre and counter-intuitive black holes can be!

The QPO is shown here as a bright patch near the inner edge of the disk of gas that feeds matter to the pulsar at the center, called SAX J1808. Guided by magnetic fields, gas streaming onto the neutron star forms bright hot spots. As the pulsar spins 401 times a second, telescopes detect X-ray pulses as these locations swing into view from Earth. When the QPO orbits more slowly than the pulsar’s spin, the neutron star’s magnetic field holds back flowing gas, dimming the X-ray pulses. But during an outburst, the inner edge of the disk is forced closer to the pulsar, resulting in a faster-moving QPO and compression of the pulsar's magnetic field. When the QPO matches or bests the pulsar’s spin, more gas streams onto the neutron star, and the pulses brighten. Gas may even flow directly onto the pulsar's equatorial region, producing extra hot spots. NASA’s Rossi X-ray Timing Explorer observed this relationship during outbursts in 2002, 2005, and 2008.

The pulsar's radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light, according to measurements by NASA's Fermi Gamma-ray Space Telescope.The system, known as AY Sextantis, is located about 4,400 light-years away in the constellation Sextans. It pairs a 1.7-millisecond pulsar named PSR J1023+0038 — J1023 for short — with a star containing about one-fifth the mass of the sun. The stars complete an orbit in only 4.8 hours, which places them so close together that the pulsar will gradually evaporate its companion. To better understand J1023's spin and orbital evolution, the system was routinely monitored in radio. These observations revealed that the pulsar's radio signal had turned off and prompted the search for an associated change in its gamma-ray properties.What's happening, astronomers say, are the last sputtering throes of the pulsar spin-up process. Researchers regard the system as a unique laboratory for understanding how millisecond pulsars form and for studying details of how accretion takes place on neutron stars. In J1023, the stars are close enough that a stream of gas flows from the sun-like star toward the pulsar. The pulsar's rapid rotation and intense magnetic field are responsible for both the radio beam and its powerful pulsar wind. When the radio beam is detectable, the pulsar wind holds back the companion's gas stream, preventing it from approaching too closely. But now and then the stream surges, pushing its way closer to the pulsar and establishing an accretion disk. When gas from the disk falls to an altitude of about 50 miles (80 km), processes involved in creating the radio beam are either shut down or, more likely, obscured. Some of the gas may be accelerated outward at nearly the speed of light, forming dual particle jets firing in opposite directions. Shock waves within and along the periphery of these jets are a likely source of the bright gamma-ray emission detected by Fermi. || ", "hits": 122 }, { "id": 30505, "url": "https://svs.gsfc.nasa.gov/30505/", "result_type": "Hyperwall Visual", "release_date": "2014-05-14T15:00:00-04:00", "title": "Hand of God", "description": "This object may look to some like a hand X-rayed at the doctor's office, but it is actually a cloud of material ejected from a star that exploded.

The stellar corpse, called PSR B1509-58, is a pulsar. It rapidly spins around, seven times per second, firing out a particle wind into the material around it — material that was ejected in the star's explosion. These particles are interacting with magnetic fields around the material, causing it to glow with X-rays. For the first time, NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has imaged a structure in high-energy X-rays (in blue). Lower-energy X-ray light previously detected by NASA's Chandra X-ray Observatory is shown in green and red. The red cloud at the end of the finger region is a different structure, called RCW 89.

No one knows the true nature of dark matter, but WIMPs, or Weakly Interacting Massive Particles, represent a leading class of candidates. Theorists have envisioned a wide range of WIMP types, some of which may either mutually annihilate or produce an intermediate, quickly decaying particle when they collide. Both of these pathways end with the production of gamma rays — the most energetic form of light — at energies within the detection range of Fermi's Large Area Telescope (LAT).The galactic center teems with gamma-ray sources, from interacting binary systems and isolated pulsars to supernova remnants and particles colliding with interstellar gas. It's also where astronomers expect to find the galaxy's highest density of dark matter, which only affects normal matter and radiation through its gravity. Large amounts of dark matter attract normal matter, forming a foundation upon which visible structures, like galaxies, are built. When the astronomers carefully subtract all known gamma-ray sources from LAT observations of the galactic center, a patch of leftover emission remains. This excess appears most prominent at energies between 1 and 3 billion electron volts (GeV) — roughly a billion times greater than that of visible light — and extends outward at least 5,000 light-years from the galactic center. The researchers find these features difficult to reconcile with other explanations proposed, such as undiscovered pulsars.

A neutron star is the crushed core of a massive star that ran out of fuel, collapsed under its own weight, and exploded as a supernova. It's the closest thing to a black hole that astronomers can observe directly, compressing half a million times Earth's mass into a ball roughly the size of Manhattan Island. Matter within a neutron star is so dense that a teaspoonful would weigh about a billion tons on Earth. Neutron stars possess two other important traits. They spin rapidly, ranging from a few rpm to as many as 43,000, comparable to the blades of a kitchen blender, and they boast magnetic fields a trillion times stronger than Earth's. About two dozen neutron stars occasionally produce high-energy explosions that astronomers say require magnetic fields thousands of times stronger than expected.

Its wide-eyed Large Area Telescope (LAT) sweeps across the entire sky every three hours, capturing the highest-energy form of light — gamma rays — from sources across the universe. These range from supermassive black holes billions of light-years away to intriguing objects in our own galaxy, such as X-ray binaries, supernova remnants and pulsars. Now a Fermi scientist has transformed LAT data of a famous pulsar into a mesmerizing movie that visually encapsulates the spacecraft's complex motion. Pulsars are neutron stars, the crushed cores of massive suns that destroyed themselves when they ran out of fuel, collapsed and exploded. The blast simultaneously shattered the star and compressed its core into a body as small as a city yet more massive than the sun. One pulsar, called Vela, shines especially bright for Fermi. It spins 11 times a second and is the brightest persistent source of gamma rays the LAT sees. The movie renders Vela's position in a fisheye perspective, where the middle of the pattern corresponds to the central and most sensitive portion of the LAT's field of view. The edge of the pattern is 90 degrees away from the center and well beyond what scientists regard as the effective limit of the LAT's vision. The movie tracks both Vela's position relative to the center of the LAT's field of view and the instrument's exposure of the pulsar during the first 51 months of Fermi's mission, from Aug. 4, 2008, to Nov. 15, 2012. The pattern Vela traces reflects numerous motions of the spacecraft. The first is Fermi's 95-minute orbit around Earth, but there's another, subtler motion related to it. The orbit itself also rotates, a phenomenon called precession. Similar to the wobble of an unsteady top, Fermi's orbital plane makes a slow circuit around Earth every 54 days. In order to capture the entire sky every two orbits, scientists deliberately nod the LAT in a repeating pattern from one orbit to the next. It first looks north on one orbit, south on the next, and then north again. Every few weeks, the LAT deviates from this pattern to concentrate on particularly interesting targets, such as eruptions on the sun, brief but brilliant gamma-ray bursts associated with the birth of stellar-mass black holes, and outbursts from supermassive black holes in distant galaxies. The Vela movie captures one other Fermi motion. The spacecraft rolls to keep the sun from shining on and warming up the LAT's radiators, which regulate its temperature by bleeding excess heat into space.Watch this video on YouTube. || ", "hits": 52 }, { "id": 3959, "url": "https://svs.gsfc.nasa.gov/3959/", "result_type": "Visualization", "release_date": "2012-09-27T00:00:00-04:00", "title": "RXTE Views X-ray Pulsar Occulted by the Moon", "description": "On Oct. 13, 2010, NASA's Rossi X-ray Timing Explorer (RXTE), a satellite in low-Earth orbit, observed a bursting X-ray pulsar as it was eclipsed by the Moon. This provided scientists with an unusual opportunity to calculate the precise position of the pulsar by timing its disappearance and reappearance at the edge of the Moon's disk.The story began a few days earlier, on Oct. 10, when the European Space Agency's INTEGRAL satellite detected a transient X-ray source in the direction of Terzan 5, a globular star cluster about 25,000 light-years away toward the constellation Sagittarius. This was the start of an extradordinary series of outbursts that ended Nov. 19. The object, dubbed IGR J17480-2446, is classed as a low-mass X-ray binary system, where a neutron star orbits a star much like the Sun and draws a stream of matter from it. As only the second bright X-ray source to be found in Terzan 5, scientists shortened the name of the system to T5X2. As shown in this animation, ingress (the moment when the pulsar disappeared) occurred on the Moon's eastern limb just above the equator. Egress, 8 minutes 32 seconds later, was near the south pole on the western limb. The timing of ingress and egress depended delicately on the shape of the terrain. In other words, it mattered whether the pulsar passed behind a mountain or a valley. So the calculation relied on the detailed topography measured by both JAXA's Kaguya and NASA's Lunar Reconnaissance Orbiter.The animation faithfully reproduces the angle of the Sun, the position of RXTE, the position and orientation of the Moon as seen from the satellite, the Moon's topography, and the starry background. RXTE's position was derived from the Goddard Flight Dynamics Facility ephemeris for day 6129 of the satellite's orbit, while the Sun and Moon positions came from JPL's DE421 solar system ephemeris. All of the positions and the viewing direction were transformed into Moon body-fixed coordinates, so that in the animation software, the Moon remained stationary at the origin, while the camera moved and pointed appropriately. The Moon, the stars, the pulsar, and the clock were all rendered separately and layered together. || ", "hits": 125 }, { "id": 3949, "url": "https://svs.gsfc.nasa.gov/3949/", "result_type": "Visualization", "release_date": "2012-05-08T00:00:00-04:00", "title": "Earth's Radiation Belts (side view)", "description": "This is a simulation of the Earth's radiation belts. In this version, we've kept the belts full structure. There is also a cross-section view of the belts in Earth's Radiation Belts (cross-section).The Earth's magnetosphere is a very large magnetic structure around the Earth, which gets stretched into a large, teardrop-shaped configuration through its interaction with the solar wind. A number of the magnetic field lines, which they may originate on the Earth, do not connect back to the Earth, but connect into the magnetic field carried by the solar wind. However, near the Earth, the dipole component of the field is stronger than the solar wind field, and this allows all the magnetic field lines to connect back to the Earth, forming (approximately) the classic magnetic dipole configuration. In this region, lower energy electrons and ions, many from the Earth's ionosphere, can become trapped by the magnetic field to form the radiation belts.The radiation belt model is constructed from particle flux information from the SAMPEX mission, with the flux mapped to constant L-shells of the Earth's dipole magnetic field. The model is anchored to the Earth's geomagnetic field axis, which is not perfectly aligned with the Earth's rotation axis. This creates a small wobble of the radiation belts with time, which can be seen in this visualization.The data driving the radiation belt structure is time-shifted from the 2003 Halloween solar storms, a series of strong solar eruptions that began in late October 2003 and continued into the first week of November. During this time, the particle content of the belts change rapidly due to the variation in the energetic particle flux from the Sun buffeting the Earth's magnetosphere. || ", "hits": 66 }, { "id": 10887, "url": "https://svs.gsfc.nasa.gov/10887/", "result_type": "Produced Video", "release_date": "2012-01-10T10:00:00-05:00", "title": "NASA's Fermi Space Telescope Explores New Energy Extremes", "description": "After more than three years in space, NASA's Fermi Gamma-ray Space Telescope is extending its view of the high-energy sky into a range that to date has been largely unexplored territory.

The outburst was first detected by NASA's Fermi Gamma-ray Space Telescope on April 12 and lasted six days.The nebula, which is the wreckage of an exploded star whose light reached Earth in 1054, is one of the most studied objects in the sky. At the heart of an expanding gas cloud lies what's left of the original star's core, a superdense neutron star that spins 30 times a second. With each rotation, the star swings intense beams of radiation toward Earth, creating the pulsed emission characteristic of spinning neutron stars (also known as pulsars). Apart from these pulses, astrophysicists regarded the Crab Nebula to be a virtually constant source of high-energy radiation. But in January, scientists associated with several orbiting observatories — including NASA's Fermi, Swift and Rossi X-ray Timing Explorer — reported long-term brightness changes at X-ray energies.Scientists think that the flares occur as the intense magnetic field near the pulsar undergoes sudden restructuring. Such changes can accelerate particles like electrons to velocities near the speed of light. As these high-speed electrons interact with the magnetic field, they emit gamma rays in a process known as synchrotron emission.To account for the observed emission, scientists say that the electrons must have energies 100 times greater than can be achieved in any particle accelerator on Earth. This makes them the highest-energy electrons known to be associated with any cosmic source.Based on the rise and fall of gamma rays during the April outbursts, scientists estimate that the size of the emitting region must be comparable in size to the solar system.
