Among these objects, scientists have cataloged over 3,000, yet they estimate there could be hundreds of thousands more, each spanning more than 10 miles in diameter, with Pluto being the most famous.Recent research using data from the Keck Observatory and NASA’s Hubble Space Telescope has revealed a potential three-body system in the Kuiper Belt, known as the Altjira system. This discovery challenges traditional collision theories by suggesting that these triple systems might form directly from the gravitational collapse of material in the early solar disk.The Altjira system, located roughly 3.7 billion miles away, demonstrates how even the most distant and faint objects can yield groundbreaking insights when observed over decades.

Before you smugly suggest \"The universe?\", check this out: 4K Videos from NASA!A little more than a decade ago, television transformed from the boxy, standard definition dimensions of 20th century engineers to the wider and sharper images of high definition TV. Well into the 21st century now, rapid growth in the next generation of video images promises to deliver spectacular pictures with profoundly greater fidelity and resolution than even the best HDTV. Officially known as Ultra-High Definition Television, it has rapidly come to be known as \"4K\", a moniker derived from the approximate width of images measured in pixels horizontally across a screen.NASA has a long legacy pushing the boundaries of advanced media technologies, befitting its unique role in presenting important, state-of-the-art science and engineering stories to the American public. On this web page you'll find the first major release of 4K video content, presented in the public domain. The release of these media are concurrent with the launch of a new, non-commercial Ultra-High Definition channel in partnership with Harmonic.

The storm formed from the collision of a cold front wrapping around a warm front, emerging over the ocean near Okinawa on March 8. It moved northeast over the ocean south of Japan, drawing cold air west-to-east over the land, a typical winter weather pattern that also brought heavy snow over Hokkaido, the northernmost of the four main islands.

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.

By analyzing a supercomputer simulation of gas flowing into a black hole, the team finds they can reproduce a range of important X-ray features long observed in active black holes. Jeremy Schnittman, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md., led the research.Black holes are the densest objects known. Stellar black holes form when massive stars run out of fuel and collapse, crushing up to 20 times the sun's mass into compact objects less than 75 miles (120 kilometers) wide. Gas falling toward a black hole initially orbits around it and then accumulates into a flattened disk. The gas stored in this disk gradually spirals inward and becomes greatly compressed and heated as it nears the center, ultimately reaching temperatures up to 20 million degrees Fahrenheit (12 million C), or some 2,000 times hotter than the sun's surface. It glows brightly in low-energy, or soft, X-rays.For more than 40 years, however, observations show that black holes also produce considerable amounts of \"hard\" X-rays, light with energy tens to hundreds of times greater than soft X-rays. This higher-energy light implies the presence of correspondingly hotter gas, with temperatures reaching billions of degrees. The new study involves a detailed computer simulation that simultaneously tracked the fluid, electrical and magnetic properties of the gas while also taking into account Einstein's theory of relativity. Using this data, the scientists developed tools to track how X-rays were emitted, absorbed, and scattered in and around the disk. The study demonstrates for the first time a direct connection between magnetic turbulence in the disk, the formation of a billion-degree corona above and below the disk, and the production of hard X-rays around an actively \"feeding\" black hole.Watch this video on YouTube. || ", "hits": 144 }, { "id": 11263, "url": "https://svs.gsfc.nasa.gov/11263/", "result_type": "Produced Video", "release_date": "2013-05-16T00:00:00-04:00", "title": "Comet Strike", "description": "Comet Shoemaker-Levy 9 was on a collision course.

While Fermi is in fine shape today, continuing its mission to map the highest-energy light in the universe, the story of how it sidestepped a potential disaster offers a glimpse at an underappreciated aspect of managing a space mission: orbital traffic control. As McEnery worked through her inbox, an automatically generated report arrived from NASA's Robotic Conjunction Assessment Risk Analysis (CARA) team based at NASA's Goddard Space Flight Center in Greenbelt, Md. On scanning the document, she discovered that Fermi was just one week away from an unusually close encounter with Cosmos 1805, a dead Cold-War era spy satellite. The two objects, speeding around Earth at thousands of miles an hour in nearly perpendicular orbits, were expected to miss each other by a mere 700 feet.Although the forecast indicated a close call, satellite operators have learned the hard way that they can't be too careful. The uncertainties in predicting spacecraft positions a week into the future can be much larger than the distances forecast for their closest approach. With a speed relative to Fermi of 27,000 mph, a direct hit by the 3,100-pound Cosmos 1805 would release as much energy as two and a half tons of high explosives, destroying both spacecraft. The update on Friday, March 30, indicated that the satellites would occupy the same point in space within 30 milliseconds of each other. Fermi would have to move out of the way if the threat failed to recede. Because Fermi's thrusters were designed to de-orbit the satellite at the end of its mission, they had never before been used or tested, adding a new source of anxiety for the team.By Tuesday, April 3, the close approach was certain, and all plans were in place for firing Fermi's thrusters. The maneuver was performed by the spacecraft based on previously developed procedures.

Two very different scenarios successfully reproduce features of this peculiar cosmic explosion. It was either caused by novel type of supernova located billions of light-years away or an unusual collision much closer to home, within our own galaxy. Common to both scenarios is the presence of a neutron star, the crushed core that forms when a star many times the sun's mass explodes. According to one science team, the burst occurred in an exotic binary system where a neutron star orbited a normal star that had just entered its red giant phase. The outer atmosphere of the giant expanded so much that it engulfed the neutron star, which resulted in both the ejection of the giant's atmosphere and rapid tightening of the neutron star's orbit. Once the two stars became wrapped in a common envelope of gas, the neutron star may have merged with the giant's core after just five orbits, or about 18 months. The end result of the merger was the birth of a black hole and the production of oppositely directed jets of particles moving at nearly the speed of light, which made the gamma rays, followed by a weak supernova. Based on this interpretation, the event took place about 5.5 billion light-years away, and the team has detected what may be a faint galaxy at the right location.Another team supports an alternative model that involves the tidal disruption of a large comet-like object and the ensuing crash of debris onto a neutron star located only about 10,000 light-years away. Gamma-ray emission occurred when debris fell onto the neutron star. Clumps of cometary material likely made a few orbits, with different clumps following different paths before settling into a disk around the neutron star.

On Dec. 11, 2010, images from the University of Arizona's Catalina Sky Survey, a project of NASA's Near Earth Object Observations Program, revealed the Scheila to be twice as bright as expected and immersed in a faint comet-like glow. Looking through the survey's archived images, astronomers inferred the outburst began between Nov. 11 and Dec. 3. Three days after the outburst was announced, Swift's Ultraviolet/Optical Telescope (UVOT) captured multiple images and a spectrum of the asteroid. Ultraviolet sunlight breaks up the gas molecules surrounding comets; water, for example, is transformed into hydroxyl (OH) and hydrogen (H). But none of the emissions most commonly identified in comets — such as hydroxyl or cyanogen (CN) — show up in the UVOT spectrum. The absence of gas around Scheila led the Swift team to reject scenarios where exposed ice accounted for the activity.Images show the asteroid was flanked in the north by a bright dust plume and in the south by a fainter one.

Now, the simulations reveal the middle step of the process—how the merging stars' magnetic field organizes itself into outwardly directed components capable of forming a jet.

This never-before-seen feature looks like a pair of bubbles extending above and below our galaxy's center. But these enormous gamma-ray emitting lobes aren't immediately visible in the Fermi all-sky map. However, by processing the data, a group of scientists was able to bring these unexpected structures into sharp relief. Each lobe is 25,000 light-years tall and the whole structure may be only a few million years old. Within the bubbles, extremely energetic electrons are interacting with lower-energy light to create gamma rays, but right now, no one knows the source of these electrons.Are the bubbles remnants of a massive burst of star formation? Leftovers from an eruption by the supermassive black hole at our galaxy's center? Or or did these forces work in tandem to produce them?

Brant Robertson and Lars Hernquist to visualize two colliding galaxies that interact and merge into a single elliptical galaxy over a period spanning two billion years of evolution. The scientific theoretical model and the computational data output were developed by Drs. Brant Robertson and Lars Hernquist. AVL rendered more than 80 gigabytes of this data using in-house rendering software and Virtual Director for camera choreography. This computation provides important research to understand galaxy mergers, and the James Webb Space Telescope (JWST) will provide data to test such theories. When two large disk-shaped galaxies merge — as will happen within the next few billion years with the Milky Way galaxy and its largest neighbor, the Andromeda Galaxy — the result will likely settle into a cloud-shaped elliptical galaxy. Most elliptical galaxies observed today formed from collisions that occurred billions of years ago. It is difficult to observe such collisions now with ground-based telescopes since these collisions are billions of light-years away. JWST will probe in unprecedented detail those distant epochs, and provide exquisite images of mergers caught in the act of destroying disk galaxies.AVL at NCSA University of Illinois || ", "hits": 187 }, { "id": 10658, "url": "https://svs.gsfc.nasa.gov/10658/", "result_type": "Produced Video", "release_date": "2010-10-28T00:00:00-04:00", "title": "Webb Science Feature - Colliding Galaxies", "description": "Deep surveys by the James Webb Space Telescope will capture the full panorama of galaxy evolution, from the earliest dwarf galaxies that formed to the familiar galaxies we see today.

The new findings confirm that the black holes \"light up\" when galaxies collide — and may offer insight into the future behavior of the black hole in our own galaxy. The intense emission from galaxy centers, or nuclei, arises near a supermassive black hole containing between a million and a billion times the sun's mass.

Far from being empty, the space between stars is filled with patchy clouds of low-density gas. When a star encounters a relatively dense clump of this gas, the resulting flow produces a drag force on orbiting dust particles about one micrometer across, or about the size of particles in smoke. As the dust particles respond to the interstellar wind, a debris disk can morph into peculiar shapes determined by the details of its collision with the gas cloud.
