Shown here are 294 gamma-ray pulsars detected by Fermi. Young pulsars, formed when massive stars explode, are the slowest rotators, typically spinning about 10 times a second. Paradoxically, their older siblings, called millisecond pulsars (MSPs), spin much faster, up to hundreds of times a second, thanks to the effects of a stream of matter pulled from a companion star. In spider systems, the companion is all but consumed. The most energetic spiders may fully evaporate their companions, leaving behind only an isolated MSP. Studying pulsars provides insights into the interplay of gravity, radiation, and magnetic fields with matter in the most extreme state we can observe directly.The WorldWide Telescope is a tool for showcasing astronomical data and knowledge. It’s not a physical telescope — it’s a suite of free and open source software and data sets that combine to create stunning scientific visualizations and stories. || ", "release_date": "2023-11-28T09:20:00-05:00", "update_date": "2023-11-27T13:38:01.449558-05:00", "main_image": { "id": 1087716, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a005100/a005144/WWT_pulsars.png", "filename": "WWT_pulsars.png", "media_type": "Image", "alt_text": "Direct link to Worldwide Telescope Gamma Ray Pulsar interactive.", "width": 1024, "height": 576, "pixels": 589824 } } }, { "id": 406107, "type": "details_page", "extra_data": null, "instance": { "id": 14281, "url": "https://svs.gsfc.nasa.gov/14281/", "page_type": "Produced Video", "title": "Fermi Spots Gamma-ray Eclipsing 'Spider Systems'", "description": "An orbiting star begins to eclipse its partner, a rapidly rotating, superdense stellar remnant called a pulsar, in this illustration.

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.

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. || ", "release_date": "2013-02-27T10:00:00-05:00", "update_date": "2023-05-03T13:52:22.501509-04:00", "main_image": { "id": 468313, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011200/a011205/Vela_Pulsar_1000.jpg", "filename": "Vela_Pulsar_1000.jpg", "media_type": "Image", "alt_text": "The Vela pulsar outlines a fascinating pattern in this movie showing 51 months of position and exposure data from Fermi's Large Area Telescope (LAT).

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. || ", "release_date": "2014-07-22T10:00:00-04:00", "update_date": "2023-05-03T13:50:44.050104-04:00", "main_image": { "id": 453317, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011600/a011609/transformerBinary_4196.jpg", "filename": "transformerBinary_4196.jpg", "media_type": "Image", "alt_text": "Narrated video.

Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars. The essential features of black widow and redback binaries are that they place a normal but very low-mass star in close proximity to a millisecond pulsar, which has disastrous consequences for the star. Black widow systems contain stars that are both physically smaller and of much lower mass than those found in redbacks.So far, astronomers have found at least 18 black widows and nine redbacks within the Milky Way, and additional members of each class have been discovered within the dense globular star clusters that orbit our galaxy. One black widow system, named PSR J1311-3430 and discovered in 2012, sets the record for the tightest orbit of its class and contains one of the heaviest neutron stars known. The pulsar's featherweight companion, which is only a dozen or so times the mass of Jupiter and just 60 percent of its size, completes an orbit every 93 minutes – less time than it takes to watch most movies. The side of the star facing the pulsar is heated to more than 21,000 degrees Fahrenheit (nearly 12,000 C), or more than twice as hot as the sun's surface. Recent studies allow a range of values extending down to 2 solar masses for the pulsar, making it one of the most massive neutron stars known.

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. If circular, the region must be smaller than roughly twice Pluto's average distance from the sun.For more Crab Nebula media go to #10708. || ", "release_date": "2011-05-11T12:00:00-04:00", "update_date": "2023-05-03T13:53:48.099907-04:00", "main_image": { "id": 486201, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a010700/a010767/Crab_nebula_Superflare_mk_II.jpg", "filename": "Crab_nebula_Superflare_mk_II.jpg", "media_type": "Image", "alt_text": "There are strange goings-on in the Crab Nebula.

From 1999 to 2008, the Crab brightened and faded by as much as 3.5 percent a year, and since 2008, it has faded by 7 percent. The Gamma-ray Burst Monitor on NASA's Fermi satellite first detected the decline, and Fermi's Large Area Telescope also spotted two gamma-ray flares at even higher energies. Scientists think the X-rays reveal processes deep within the nebula, in a region powered by a rapidly spinning neutron star — the core of the star that blew up.

Located about 15,000 light-years away in the constellation Norma, the magnetar was quiet until October 2008, when it entered a period of eruptive activity that ended in April 2009. At times, the object produced hundreds of bursts in as little as 20 minutes, and the most intense explosions emitted more total energy than the sun does in 20 years. High-energy instruments on many spacecraft, including NASA's Swift and Rossi X-ray Timing Explorer, detected hundreds of gamma-ray and X-ray blasts.An examination of 263 individual bursts detected by Fermi's Gamma-ray Burst Monitor confirms vibrations in the frequency ranges previously only seen in rare giant flares from magnetars. Astronomers suspect these are twisting oscillations of the star where the crust and the core, bound by the magnetic field, vibrate together. In addition, a single burst showed an oscillation at a frequency never seen before and which scientists still do not understand.While there are many efforts to describe the interiors of neutron stars, scientists lack enough observational detail to choose between differing models. Neutron stars reach densities far beyond the reach of laboratories and their interiors may exceed the density of an atomic nucleus by as much as 10 times.

In June 2013, the pulsar underwent a dramatic change in behavior never before observed. Its radio beacon vanished, while at the same time the system brightened significantly in gamma rays, the highest-energy form of light.The stellar system, known as AY Sextantis and located about 4,400 light-years away in the constellation Sextans, 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 a high-energy \"wind\" of charged particles from the pulsar is gradually evaporating its companion. What's happening, astronomers say, are the last sputtering throes of the pulsar spin-up process, where a flow of matter from the companion has, over millions of years, dramatically increased the pulsar's rotation. J1023 now spins at about 35,000 rpm, but the gas stream from the companion is no longer continuous.

When the radio beam (green) is detectable, the pulsar wind holds back the companion's gas stream, preventing it from approaching too closely. Now and then the stream surges, reaches toward the pulsar and establishes an accretion disk. Processes involved in producing the radio beam are either shut down or, more likely, obscured. Meanwhile, some of the gas falling toward the pulsar 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 (magenta) detected by NASA's Fermi Gamma-ray Space Telescope.Credit: NASA's Goddard Space Flight Center", "width": 1920, "height": 1080, "pixels": 2073600 } } }, { "id": 406130, "type": "details_page", "extra_data": null, "instance": { "id": 11215, "url": "https://svs.gsfc.nasa.gov/11215/", "page_type": "Produced Video", "title": "PSR J1311-3430 'Black Widow' Pulsar Animations", "description": "The essential features of black widow binaries, and their cousins, known as redbacks, are that they place a normal but very low-mass star in close proximity to a millisecond pulsar, which has disastrous consequences for the star.
