            "description": "The Solar and Heliospheric Observatory (SOHO), a joint mission of ESA (European Space Agency) and NASA, has discovered its 5,000th comet, thanks to the help of volunteer comet hunters participating in the NASA-funded Sungrazer Project.The sungrazing comet was spotted in SOHO images on March 25, 2024, by Hanjie Tan in the Czech Republic, who has participated in the Sungrazer Project since he was 13 years old. The comet is small and has a short orbital period around the Sun. It belongs to the “Marsden group” of comets, which are thought to be related to the larger comet 96P/Machholz. The group is named after the late scientist Brian Marsden, who first recognized the group using SOHO observations.To learn more about the discovery and SOHO, visit: https://science.nasa.gov/science-research/heliophysics/esa-nasa-solar-observatory-discovers-its-5000th-comet/Since the early 2000s, the Sungrazer Project has allowed anyone with a computer to search for comets in images taken by the SOHO spacecraft.To learn more about the Sungrazer Project, visit: https://science.nasa.gov/citizen-science/the-sungrazer-project/ || ",

Before the launch in 1995 of the NASA and European Space Agency's   Solar and Heliospheric Observatory satellite (known as SOHO) there were about 900 known comets. After 20 years SOHO has just spotted its 3000th comet. 2. SOHO's ability to spot comets turns out to be an unplanned and unexpected benefit. 3. SOHO's main job is to study the sun, not comets. But citizen scientists and astronomers from around the world combing through SOHO data have greatly expanded our knowledge about comets. 4. An amateur astronomer in Thailand spotted number 3,000.TAG: Citizen scientists, including two 13-year-olds, have found 95 percent of SOHO comets. || NASAONAIR_Comets-10-iPad_print.jpg (1024x576) [85.1 KB] || NASAONAIR_Comets-10-iPad_searchweb.png (320x180) [61.7 KB] || NASAONAIR_Comets-10-iPad_thm.png (80x40) [4.7 KB] || NASAONAIR_Comets-1_Weather_Channel_30_fps.mov (1920x1080) [905.0 MB] || NASAONAIR_Comets-2_Weather_Channel_60_fps.mov (1280x720) [948.5 MB] || NASAONAIR_Comets-3_NBC_Today.mov (1920x1080) [534.1 MB] || NASAONAIR_Comets-4-WeatherChannel.wmv (1280x720) [6.2 MB] || NASAONAIR_Comets-5-Accuweather.avi (1280x720) [5.4 MB] || NASAONAIR_Comets-6_Baron_Services_MP4.mp4 (1920x1080) [21.2 MB] || NASAONAIR_Comets-7_APR_422_1920_30.mov (1920x1080) [490.6 MB] || NASAONAIR_Comets-8-iPad.m4v (960x540) [12.1 MB] || NASAONAIR_Comets-9-iPad.m4v (1280x720) [7.9 MB] || NASAONAIR_Comets-10-iPad.m4v (1920x1080) [11.4 MB] || NASAONAIR_Comets-10-iPad.webm (1920x1080) [2.5 MB] || ",

Traveling at 33 miles per second and weighing as much as a small mountain, the comet hails from the outer fringes of our solar system, originating in a region of icy debris known as the Oort cloud.Comets from the Oort cloud are both ancient and rare. Since this is Comet Siding Spring’s first trip through the inner solar system, scientists are excited to learn more about its composition and the effects of its gas and dust on the Mars upper atmosphere.NASA will be watching closely before, during, and after the flyby with its entire fleet of Mars orbiters and rovers, along with the Hubble Space Telescope and dozens of instruments on Earth. The encounter is certain to teach us more about Oort cloud comets, the Martian atmosphere, and the solar system’s earliest ingredients. || ",

Would the comet disintegrate in the fierce heat and gravity of the sun? Or survive intact to appear as a bright comet in the pre-dawn sky? Some remnant of ISON did indeed make it around the sun, but it quickly dimmed and fizzled as seen with NASA's solar observatories. This does not mean scientists were disappointed, however. On Dec. 10, 2013, researchers presented science results from the comet's last days at the 2013 Fall American Geophysical Union meeting in San Francisco, Calif. They described how this unique comet lost mass in advance of reaching perihelion and most likely broke up during its closest approach, as well, as summarized what this means for determining what the comet was made of. The panel shared results from the Solar and Heliospheric Observatory (SOHO), the Solar Terrestrial Relations Observatory (STEREO), the Mars Reconnaissance Orbiter (MRO) and MESSENGER to present a picture of ISON's trip around the sun, which appears to have led to its demise.  The panel also reported on why ISON was not seen in images from the Solar Dynamics Observatory (SDO). || ",

            "description": "A comet's journey through the solar syste is perilous and violent. Before it reaches Mars - at some 230 million miles away from the sun - the radiation of the sun begins to cook off the frozen water ice directly into gas. This is called sublimation. It is the first step toward breaking the comet apart. If it survives this, the intense radiation and pressure closer to the sun could destroy it altogether.Animators at NASA's Goddard Space Flight Center in Greenbelt, Md. created this short movie showing how the sun can cook a comet. Such a journey is currently being made by Comet ISON. It began its trip from the Oort cloud region of our solar system and is now traveling toward the sun. The comet will reach its closest approach to the sun on Thanksgiving Day — Nov. 28, 2013 — skimming just 730,000 miles above the sun’s surface. If it comes around the sun without breaking up, the comet will be visible in the Northern Hemisphere with the naked eye, and from what we see now, ISON is predicted to be a particularly bright and beautiful comet. Even if the comet does not survive, tracking its journey will help scientists understand what the comet is made of, how it reacts to its environment, and what this explains about the origins of the solar system. Closer to the sun, watching how the comet and its tail interact with the vast solar atmosphere can teach scientists more about the sun itself. || ",

            "description": "There is a “new” comet in our neighborhood. 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. || ",

            "description": "Sungrazing comets are a special class of comets that come very close to the sun at their nearest approach, a point called perihelion. To be considered a sungrazer, a comet needs to get within about 850,000 miles from the sun at perihelion. Many come even closer, even to within a few thousand miles. Being so close to the sun is very hard on comets for many reasons. They are subjected to a lot of solar radiation which boils off their water or other volatiles. The physical push of the radiation and the solar wind also helps form the tails. And as they get closer to the sun, the comets experience extremely strong tidal forces, or gravitational stress. In this hostile environment, many sungrazers do not survive their trip around the sun. Although they don't actually crash into the solar surface, the sun is able to destroy them anyway. Many sungrazing comets follow a similar orbit, called the Kreutz Path, and collectively belong to a population called the Kreutz Group. In fact, close to 85% of the sungrazers seen by the SOHO satellite are on this orbital highway. Scientists think one extremely large sungrazing comet broke up hundreds, or even thousands, of years ago, and the current comets on the Kreutz Path are the leftover fragments of it. As clumps of remnants make their way back around the sun, we experience a sharp increase in sungrazing comets, which appears to be going on now. Comet Lovejoy, which reached perihelion on December 15, 2011 is the best known recent Kreutz-group sungrazer. And so far, it is the only one that NASA's solar-observing fleet has seen survive its trip around the sun. Comet ISON, an upcoming sungrazer with a perihelion of 730,000 miles on November 28, 2013, is not on the Kreutz Path. In fact, ISON's orbit suggests that it may gain enough momentum to escape the solar system entirely, and never return. Before it does so, it will pass within about 40 million miles from Earth on December 26th. Assuming it survives its trip around the sun. || ",

Observatories around the world and in space will track the comet during its fiery trek around the sun. If ISON survives its searing solar passage, which seems likely but is not certain, the comet may be visible to the unaided eye in the pre-dawn sky during December.Watch the animations on this page to visualize ISON's voyage through the inner solar system, or build the paper model of its orbit to track the changing positions of Earth and the comet.Like all comets, ISON is a clump of frozen gases mixed with dust. Often described as \"dirty snowballs,\" comets emit gas and dust whenever they venture near enough to the sun that the icy material transforms from a solid to gas, a process called sublimation. Jets powered by sublimating ice also release dust, which reflects sunlight and brightens the comet. On Nov. 28, ISON will make a sweltering passage around the sun. The comet will approach within about 730,000 miles (1.2 million km) of its visible surface, which classifies ISON as a sungrazing comet. In late November, its icy material will furiously sublimate and release torrents of dust as the surface erodes under the sun's fierce heat, all as sun-monitoring satellites look on. Around this time, the comet may become bright enough to glimpse just by holding up a hand to block the sun's glare.Sungrazing comets often shed large fragments or even completely disrupt following close encounters with the sun, but for ISON neither fate is a forgone conclusion.Following ISON's solar swingby, the comet will depart the sun and move toward Earth, appearing in morning twilight through December. The comet will swing past Earth on Dec. 26, approaching within 39.9 million miles (64.2 million km) or about 167 times farther than the moon.The comet was discovered on Sept 21, 2012, by Russian astronomers Vitali Nevski and Artyom Novichonok using a telescope of the International Scientific Optical Network (ISON) located near Kislovodsk.Learn more about sungrazing comets. || ",

With solar observatories like SOHO, STEREO, and SDO, we have not only better means of viewing the sun, but also the comets that approach it. SOHO allows us to see smaller, fainter comets closer to the sun than we have ever been able to see before. Even though many of these comets do not survive their journey past the sun, they survive long enough to be observed, and be added to our record of sungrazing comets. || ",

            "description": "To observe how winds move high in Earth's atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around — but scientists have no similar technique to study the turbulent atmosphere of the sun. So researchers were excited in December 2011, when Comet Lovejoy swept right through the sun's corona with its long tail streaming behind it. NASA's Solar Dynamics Observatory (SDO) captured images of the comet, showing how its long tail was buffeted by systems around the sun, offering scientists a unique way of observing movement as if they'd orchestrated the experiment themselves. Since comet tails have ionized gases, they are also affected by the sun's magnetic field, and can act as tracers of the complex magnetic system higher up in the atmosphere. Comets can also aid in the study of coronal mass ejections and the solar wind.Watch this video on YouTube. || ",

Not only does this help with comet research, but it also helps orient instruments on SDO—since the scientists know where the comet is based on other spacecraft, they can finely determine the position of SDO's mirrors. This first clip from SDO from the evening of Dec 15, 2011 shows Comet Lovejoy moving in toward the sun. Comet Lovejoy survived its encounter with the sun. The second clip shows the comet exiting from behind the right side of the sun, after an hour of travel through its closest approach to the sun. By tracking how the comet interacts with the sun's atmosphere, the corona, and how material from the tail moves along the sun's magnetic field lines, solar scientists hope to learn more about the corona. This movie was filmed by the Solar Dynamics Observatory in 171 angstrom wavelength, which is typically shown in yellow.Credit: NASA/SDO || ",

            "description": "The Christmas burst, also known as GRB 101225A, was discovered in the constellation Andromeda by Swift's Burst Alert Telescope at 1:38 p.m. EST on Dec. 25, 2010. 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. X-ray variations detected by Swift's X-Ray Telescope that lasted several hours may have resulted from late-arriving clumps that struck the neutron star as the disk formed. The NASA release is here. || ",

By comparing the reflected red, blue, and green light from planets in our solar system, a team led by Crow and McFadden was able to group the planets according to their similarities. As it turns out, the planets fall into very distinct regions on this plot, where the vertical direction indicates the relative amount of blue light, and the horizontal direction the relative amount of red light. This technique works even when the source of the reflected light is visible only as a point, like exoplanets appear when observed through a telescope. Therefore, scientists can use it to identify earthlike planets more easily. || ",
