This artist's concept shows one interpretation of the system. High-resolution X-ray spectroscopy indicates two gas components: a heavy background outflow, or wind, produced by the massive star and a turbulent structure — perhaps a wake carved into the wind — located close to the orbiting companion. As shown here, a black hole's gravity captures some of the wind into an accretion disk around it, and the disk's orbital motion sculpts a path (yellow arc) through the streaming gas. During strong outbursts, the companion emits jets of particles moving near the speed of light, seen here extending above and below the black hole.Credit: NASA’s Goddard Space Flight CenterAlt text: Illustration of the Cygnus X-3 systemImage description: On a cloudy reddish background, a bright blue-white circle — a representation of a hot, bright, massive star — sits near the center. Wisps of blue-white border its edges, and many lines of similar color radiate from it. In the foreground at about 4 o’clock lies a yellowish ring with a black hole in its center. From the ring trails a diffuse yellow arc, sweeping from right to left and exiting at the bottom of the illustration.

Where everyone was afraid the world was going to end because computer programmers saved space by putting dates as… 77 for 1977. 85 for 1985. Or 90 for 1990. But then it became clear that when the year 2000 finally rolled around all of the computers would think it was actually 00. Or the year 1900.Well, it turns out Hubble has something similar, only Hubble’s clock restarts every 6,213 days, 18 hours, 48 minutes, and 31.875 seconds. Or roughly every 17 years for those of you who like counting.That’s because Hubble’s computers have a different way of tracking time than we have here on the ground. You’d think it would be as simple as synching our ground clocks with Hubble’s personal timepiece, but you’d be surprised. For more information, visit https://nasa.gov/hubble.

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!

Merger events like this are thought to occur as often as every three to four billion years in clusters like Perseus.Credit: NASA's Goddard Space Flight CenterMusic: \"The Undiscovered\" from Killer TracksWatch this video on the NASA Goddard YouTube channel.Complete transcript available. || Perseus_Simulation_Final_Frame_print.jpg (1024x575) [47.6 KB] || Perseus_Simulation_Final_Frame.png (7342x4129) [4.0 MB] || Perseus_Simulation_Final_Frame_thm.png (80x40) [3.3 KB] || Perseus_Simulation_Final_Frame_searchweb.png (320x180) [39.3 KB] || 12587_Perseus_Wind_FINAL_VX-281959_appletv_subtitles.m4v (1280x720) [85.7 MB] || 12587_Perseus_Wind_1080.webm (1920x1080) [18.2 MB] || 12587_Perseus_Wind_FINAL_VX-281959_appletv.m4v (1280x720) [85.6 MB] || 12587_Perseus_Wind_1080.m4v (1920x1080) [160.3 MB] || 12587_Perseus_Wind_1080.mov (1920x1080) [241.7 MB] || 12587_Perseus_Wind_SRT_Caption.en_US.vtt [1.7 KB] || 12587_Perseus_Wind_SRT_Caption.en_US.srt [1.7 KB] || WMV_12587_Perseus_Wind_FINAL_VX-281959_HD.wmv (3840x2160) [154.8 MB] || 12587_Perseus_Wind.mp4 (3840x2160) [306.3 MB] || 12587_Perseus_Wind_Good_4k.mov (3840x2160) [468.4 MB] || 12587_Perseus_Wind_4K.m4v (3840x2160) [792.0 MB] || 12587_Perseus_Wind_FINAL_VX-281959_youtube_hq.mov (3840x2160) [1.2 GB] || 12587_Perseus_Wind_ProRes_3840x2160_2997.mov (3840x2160) [5.2 GB] || ", "hits": 109 }, { "id": 4537, "url": "https://svs.gsfc.nasa.gov/4537/", "result_type": "Visualization", "release_date": "2016-12-22T15:00:00-05:00", "title": "Moon Phase and Libration, 2017", "description": " || Dial-A-Moon || moon.0001.jpg (730x730) || comp.0001.tif (5760x3240) || ", "hits": 245 }, { "id": 4538, "url": "https://svs.gsfc.nasa.gov/4538/", "result_type": "Visualization", "release_date": "2016-12-22T15:00:00-05:00", "title": "Moon Phase and Libration, 2017 South Up", "description": " || Dial-A-Moon || moon.0001.jpg (730x730) || comp.0001.tif (5760x3240) || ", "hits": 93 }, { "id": 12375, "url": "https://svs.gsfc.nasa.gov/12375/", "result_type": "Produced Video", "release_date": "2016-09-26T14:00:00-04:00", "title": "Hubble Directly Images Possible Plumes on Europa", "description": "NASA's Hubble Space Telescope took direct ultraviolet images of the icy moon Europa transiting across the disk of Jupiter.

These powerful outbursts in a known gravitational lens provided the key to making the measurement. Astronomers classify B0218+357 as a blazar, a type of active galaxy noted for intense outbursts. At the blazar's heart is a supersized black hole with a mass millions to billions of times that of the sun. As matter spirals toward this black hole, some of it blasts outward as jets of particles traveling near the speed of light in opposite directions.Long before light from B0218+357 reaches us, it passes directly through a spiral galaxy – one much like our own – located 4.03 billion light-years away. The galaxy's gravity bends the light into different paths, so astronomers see the background blazar as dual images. But these paths aren't the same length, which means that when one image flares, there's a delay of many days before the other does.While radio and optical telescopes can resolve and monitor the individual blazar images, Fermi's LAT cannot. Instead, the Fermi team exploited the playback delay between the images. In September 2012, when the blazar's flaring activity made it the brightest gamma-ray source outside of our own galaxy, Fermi scientists took advantage of the opportunity by using a week of dedicated LAT time to hunt for delayed flares. Three episodes of flares showing playback delays of 11.46 days were found, with the strongest evidence in a sequence of flares captured during the week-long LAT observations. || ", "hits": 97 }, { "id": 4118, "url": "https://svs.gsfc.nasa.gov/4118/", "result_type": "Visualization", "release_date": "2013-12-06T00:01:00-05:00", "title": "Moon Phase and Libration, 2014", "description": " || The data in the table for the entire year can be downloaded as a JSON file or as a text file. || moon.0001.jpg (730x730) [27.9 KB] || comp.0001.tif (1920x1080) [1.5 MB] || ", "hits": 156 }, { "id": 4119, "url": "https://svs.gsfc.nasa.gov/4119/", "result_type": "Visualization", "release_date": "2013-12-06T00:01:00-05:00", "title": "Moon Phase and Libration, 2014 South Up", "description": " || The data in the table for the entire year can be downloaded as a JSON file or as a text file. || moon.0001.jpg (730x730) [27.7 KB] || comp.0001.tif (1920x1080) [1.5 MB] || ", "hits": 46 }, { "id": 4109, "url": "https://svs.gsfc.nasa.gov/4109/", "result_type": "Visualization", "release_date": "2013-10-02T00:00:00-04:00", "title": "Lunar Far Side: From Luna 3 to LRO", "description": "In October of 1959, the Luna 3 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan. Luna 3 was the third spacecraft to reach the Moon and the first to send back pictures of the Moon's far side. The pictures were noisy and indistinct, but because the Moon always presents the same face to the Earth, they offered views of a part of the Moon that had never been seen before.The far side of the Moon is surprisingly different. The most striking difference evident in the Luna 3 pictures is the absence of the large, dark seas of cooled lava, called maria, that cover a substantial fraction of the Earth-facing near side. The far side is instead densely peppered with impact craters of every size and age.Fifty years later, in June of 2009, Lunar Reconnaissance Orbiter (LRO) launched from Kennedy Space Center in Florida. Using LRO's global elevation maps and photographic mosaics, both of which are of unprecedented quality and detail, it's possible to accurately recreate the view captured in the pictures from Luna 3. As seen here, Luna 3 was directly over 12°N 120°E at a distance of 61,700 kilometers above the surface, and its camera was banked 17.5° clockwise from vertical relative to the Moon's north pole.The thicker blue longitude line at 90°E, along the left side of the LRO image, marks the boundary between the near and far sides of the Moon. To the left of that line are the familiar maria Crisium (the circular spot near the 9 o'clock position), Marginis, Smythii (both east of Crisium), Humboldtianum (in the north), Australe (near the south pole), and the eastern edge of Fecunditatis. The bright spot near the center of the disk is a complex of unnamed craters bordered by King, Langemak, Gregory, and Abul Wafa craters. The brightness is enhanced because it's near the subsolar point. The dark, sharp-edged shield shape in the southern hemisphere, with the white dot in the middle, is Tsiolkovskiy crater and its central peak. The dark spot to the southeast of Tsiolkovskiy is the crater Jules Verne.

The LAMP sensor is a 6.0° x 0.3° slit that was positioned to look over the limb of the Moon, so that it would be pointed into the tenuous dust plume with only the sky in the background.

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": 120 }, { "id": 3971, "url": "https://svs.gsfc.nasa.gov/3971/", "result_type": "Visualization", "release_date": "2012-05-28T12:00:00-04:00", "title": "Global Precipitation Measurement (GPM) Constellation", "description": "Nine U.S. and international satellites will soon be united by the Global Precipitation Measurement (GPM) mission, a partnership co-led by NASA and the Japan Aerospace Exploration Agency (JAXA).

The GPM Core satellite carries two instruments: a state-of-the-art radiometer called the GPM Microwave Imager (GMI) and the first space-borne Dual-frequency Precipitation Radar (DPR), which sees the 3D structure of falling rain and snow. The DPR and GMI work in concert to provide a unique database that will be used to improve the accuracy and consistency of measurements from all partner satellites, which will then be combined into the uniform global precipitation dataset. In this animation the orbit paths of the partner satellites of the GPM constellation fill in blue as the instruments pass over Earth. Rainfall appears light blue for light rain, yellow for moderate, and red for heavy rain. Partner satellites are traced in green and purple, and the GPM Core is traced in red. The GPM Core observatory is currently being built and tested at NASA's Goddard Space Flight Center in Greenbelt, Md.

This geometric transformation was sparked by a farming method called center-pivot irrigation, which pumps water through an extended sprinkler system that rotates like the hand of a clock, necessitating circular fields. Farmers around Dalhart have gradually adopted center-pivot irrigation since its introduction in 1949; it is ideal for the region's rolling, sandy terrain and delivers water with minimal loss to evaporation.

They were taken on December 24, 1968 by the crew of Apollo 8, the first humans to leave low Earth orbit.The sight of a small, intensely blue Earth rising above the barren, gray horizon of the Moon was one of the few things that NASA and the crew of Apollo 8 had not thoroughly planned and rehearsed beforehand. As historian Robert Poole noted, this lack of preparation meant that the sight of Earth came with the force of a revelation, not just for the astronauts but for everyone on the ground. We came all this way to explore the Moon, Apollo 8 astronaut Bill Anders said, and the most important thing is that we discovered the Earth.Using the latest elevation data from Lunar Reconnaissance Orbiter, this visualization attempts to recreate what the astronauts saw. The virtual camera of the rendering software is put in the position of the Apollo 8 spacecraft at the time of the photographs, as the spacecraft emerged from its fourth pass behind the Moon. It shows a two-minute interval centered on 16:39:06 UT (10:39 a.m. Houston time) on December 24, 1968. This is around the time of AOS (acquisition of signal), the moment when radio contact is re-established after being lost on the far side of the Moon.The position and motion of the spacecraft are based on a state vector, a set of (x, y, z) position and (vx, vy, vz) velocity values, published in NASA's Apollo 8 Mission Report about a year after the flight. The animator translated these values, given in Moon-centered inertial coordinates for Besselian year 1969.0, into a modern coordinate system, then calculated an orbit. The spacecraft was 110 km (68 miles, 60 nautical miles) above the surface of the Moon at 11.2°S 113.8°E when the Earthrise photograph was taken. || ", "hits": 1446 }, { "id": 10961, "url": "https://svs.gsfc.nasa.gov/10961/", "result_type": "Produced Video", "release_date": "2012-04-19T00:00:00-04:00", "title": "NASA's Lunar Reconnaissance Orbiter Brings \"Earthrise\" to Everyone", "description": "On December 24, 1968, Apollo 8 Commander Frank Borman and crew members William A.
