Discovered in September 2012 by two Russian scientists, it has officially been designated as C2012/S1, but the world has come to know it as comet ISON—an acronym for the Russian International Science Observation Network through which it was discovered. Here, the comet looks like a bright white smudge [top right] among other colorful distant stars and galaxies on a canvas that depicts interstellar space. NASA's Hubble Space Telescope observed ISON on April 30, 2013, as it passed near the orbit of Jupiter. The resulting image, shown here, combines observations from two Hubble filters and is a simulation of what our eyes, with their ability to dynamically adjust to brighter and fainter objects, would see if we could look up at the heavens with the resolution of Hubble. One filter lets in red light, represented as faint red shades, while the other filter lets in a greenish-yellow light, represented as faint blue shades. In general, faint red objects are older and more evolved than blue objects—this is true both for the crosshair-spiked stars and the smaller and dimmer smudges of distant galaxies. This newly discovered comet is believed to have originated in the Oort Cloud—a “source region” for many comets, located on the fringe of the solar system. Scientists believe that ISON is making its very first trek toward the sun, and its first known visit will be an extremely close encounter—making the potential for new discovery very high.Used in 2014 SMD Calendar. || ", "hits": 31 }, { "id": 11116, "url": "https://svs.gsfc.nasa.gov/11116/", "result_type": "Produced Video", "release_date": "2012-10-25T10:00:00-04:00", "title": "Reviving Fomalhaut b", "description": "A second look at data from NASA's Hubble Space Telescope is reanimating the claim that the nearby star Fomalhaut hosts a massive exoplanet. The study suggests that the planet, named Fomalhaut b, is a rare and possibly unique object that is completely shrouded by dust. Fomalhaut is the brightest star in the constellation Piscis Austrinus and lies 25 light-years away. In November 2008, Hubble astronomers announced the exoplanet, named Fomalhaut b, as the first one ever directly imaged in visible light around another star. The object was imaged just inside a vast ring of debris surrounding but offset from the host star. The planet's location and mass — about three times Jupiter's — seemed just right for its gravity to explain the ring's appearance. Recent studies have claimed that this planetary interpretation is incorrect. Based on the object's apparent motion and the lack of an infrared detection by NASA's Spitzer Space Telescope, they argue that the object is a short-lived dust cloud unrelated to any planet. A new analysis, however, brings the planet conclusion back to life.Watch this video on YouTube. || ", "hits": 181 }, { "id": 10747, "url": "https://svs.gsfc.nasa.gov/10747/", "result_type": "Produced Video", "release_date": "2011-04-28T09:00:00-04:00", "title": "Swift and Hubble Probe an Asteroid Crash", "description": "Late last year, astronomers noticed that an asteroid named Scheila had unexpectedly brightened and it was sporting short-lived plumes. Data from NASA's Swift satellite and Hubble Space Telescope show that these changes likely occurred after Scheila was struck by a much smaller asteroid. 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. The dual plumes formed as small dust particles excavated by the impact were pushed away from the asteroid by sunlight. Hubble observed the asteroid's fading dust cloud on Dec. 27, 2010, and Jan. 4, 2011.The two teams found the observations were best explained by a collision with a small asteroid impacting Scheila's surface at an angle of less than 30 degrees, leaving a crater 1,000 feet across. Laboratory experiments show a more direct strike probably wouldn't have produced two distinct dust plumes. The researchers estimated the crash ejected more than 660,000 tons of dust—equivalent to nearly twice the mass of the Empire State Building.For the collision animation go to #10759. || ", "hits": 70 }, { "id": 10564, "url": "https://svs.gsfc.nasa.gov/10564/", "result_type": "Produced Video", "release_date": "2010-02-03T00:00:00-05:00", "title": "Hubble IMAX: Educator Resources", "description": "Table of Contents+ Build a Robotic Arm+ Communication Station+ Images from Hubble Simulation Build a Robotic Arm || See a robotic arm at work in the \"Servicing Mission 4 Essentials\" site at http://www.nasa.gov/mission_pages/hubble/servicing/SM4/main/SM4_Essentials.html. || build_a_mission_tool_272861main_ess_2astronauts_arm_600x400.jpg (600x400) [240.0 KB] || build_a_mission_tool_272861main_ess_2astronauts_arm_600x400_web.png (320x213) [344.6 KB] || ", "hits": 24 }, { "id": 10474, "url": "https://svs.gsfc.nasa.gov/10474/", "result_type": "Produced Video", "release_date": "2009-07-27T00:00:00-04:00", "title": "Hubble Career Profiles", "description": "These profiles begin to explore what systems engineering is as seen through the roles of Benjamin Reed and Jackie Townsend on the Hubble Space Telescope.
