The research was unveiled Tuesday at the 221st meeting of the American Astronomical Society in Long Beach, Calif. Top News. Fomalhaut B: The Zombie Planet. The planet orbits the dust-shrouded star Fomalhaut and is located about 25 light-years away in the constellation Piscis Austrinus. Dec. 8, 1990: Jupiter-bound Galileo probe flies by Earth, Chuck Yeager, 1st pilot to break the sound barrier, is dead at 97, Right ascension: 22 hours 57 minutes 39.1 seconds, Declination: -29 degrees 37 minutes 20 seconds. ", As knowledge of the stars improved, Fomalhaut was classified as a "class A" star that has a surface temperature of about 8,500 Kelvin (roughly 14,840 F or 8,225 C), according to astronomer Jim Kaler. Its apparent magnitude is 1.16, making it the 18th brightest star in the night sky. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. The debris belt spans a vast region of space between 14 billion and 20 billion miles around the star. "I was really surprised," study leader Bram Acke of the University of Leuven in Belgium said in a statement at the time. Then in 2008, astronomers again using Hubble announced they not only had found a planet (Fomalhaut b), but also had taken a picture of it in visible light – the first time that had ever happened. (Hmm, … The unbalanced orbit of a so-called "zombie planet" in a dusty star system has astronomers struggling to explain the exoplanet's behavior. [Gallery: The Strangest Alien Planets]. And if you have a news tip, correction or comment, let us know at: community@space.com. Stranger still: The planet Fomalhaut b appears to approach with 4.6 billion miles of its star at the closest point in its orbit, then swing way out to a point about 27 billion miles away at the farthest point. The planet follows a highly elliptical orbit that carries it across a wide belt of debris encircling the bright star Fomalhaut. This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. If Fomalhaut b is not in the same plane as the debris disk, then it should gradually get dimmer as it gets farther and farther from its parent star, researchers said. It was the first alien planet ever directly imaged in visible light. The Tables, however, spelled the name as "Fomahant." Instead of being centered on the star, the dust ring was offset in such a way that a planet likely caused the disturbances, astronomers said at the time. Comments Off on The Strange Case of “Zombie” Planet Fomalhaut b; The timing couldn’t have been more perfect – just days before Halloween, NASA released a story about a planet that had returned from the dead. Fomalhaut's location is: In 2002, astronomers estimated a Saturn-size planet was lurking within Fomalhaut's dust ring, which is a common feature among young stars. New observations of the planet Fomalhaut b by the Hubble Space Telescope revealed the oddball orbit, which has wild extremes between its closest and farthest points … Market data provided by Factset. Fomalhaut b is a confirmed, directly-imaged extrasolar object and candidate planet orbiting the A-type main-sequence star Fomalhaut, approximately 25 light-years away in the constellation of Piscis Austrinus.The object was initially announced in 2008 and confirmed as real in 2012 from images taken with the Advanced Camera … This infrared image shows the young star Fomalhaut and its surrounding dust disc it as seen with ESA's Herschel space observatory. More about Fomalhaut B, Zombie Planet, NASA, Space, Hubble telescope Latest News. Called “zombie planet” – its existence has been announced, later denied, then finally confirmed in 2012, making it a comeback from the “academic dead” – this huge planet … Future US, Inc. 11 West 42nd Street, 15th Floor, ©2020 FOX News Network, LLC. More intriguing findings came to light in 2012, when scientists found evidence of a swarm of comets orbiting the star. New observations of the planet Fomalhaut b by the Hubble Space Telescope revealed the oddball orbit, which has wild extremes between its closest and farthest points from the parent star and appears to cross through a vast minefield of dusty debris. It was the first alien planet ever directly imaged in visible light. Mutual Fund and ETF data provided by Refinitiv Lipper. Keep your children close – zombie planet roams once more. The dust ring was actually discovered in the 1980s, but came into greater scrutiny through observations from the European Space Agency's Herschel observatory. Observers noted an unusually high amount of dust in the system, which was unexpected because the starlight from Fomalhaut would be thought to push it away. "Since we do observe emission from dust in the disc, this blow-out effect must be compensated by a steady production of dust particles via comet collisions," co-author Carsten Dominik of the University of Amsterdam and Radboud Universiteit Nijmegen said in a statement. That would make the planet increase its brightness in infrared light, they added. © "Almost the same distance as Vega, it is over a full magnitude fainter to the eye as a result of somewhat lower mass of 2.0 solar, which results in a lower surface temperature and smaller size of 1.8 times that of the sun," Kaler wrote. The Strange Case of “Zombie” Planet Fomalhaut b. Quotes displayed in real-time or delayed by at least 15 minutes. The cosmic close encounter could have gravitationally ejected Fomalhaut b into its current orbit, scientists said. The already strange star system of Fomalhaut has gotten even stranger. ‘T. In November 2008, Hubble astronomers announced the exoplanet, named Fomalhaut b, as the first … 'Zombie planet' gets weirder Fomalhaut b is a giant alien planet that is nearly three times the mass of Jupiter. Fomalhaut B, The Zombie Planet. Legal Statement. Thank you for signing up to Space. The star has been called by many variations of the name over the centuries, but with the advent of modern astronomy the name was formalized as "Fomalhaut. There was a problem. Another tantalizing theory suggests Fomalhaut b may have Saturn-like rings and be destined for a spectacular crash through the debris disk around the star Fomalhaut in the year 2032. Jan. 8, 2013: A photograph of rogue planet Fomalhaut b. Jan. 8, 2013: This diagram shows the orbit of the exoplanet Fomalhaut b as calculated from recent Hubble Space Telescope observations. Get breaking space news and the latest updates on rocket launches, skywatching events and more! Three years later, pictures of the system revealed Fomalhaut and the dust ring looking almost like "the eye of Sauron," a reference from J.R.R. The equivalent mass of the material in Fomaulhaut's system would be about 110 Earths, a research team said. Fomalhaut b. Astronomers suspect Fomalhaut's debris disc stems from dust particles created by prolific comet collisions, with an average rate of 2,000 daily crashes between comets of 1 kilometer across. The available targets are included in a list of 305 exoplanets discovered prior to 31 December 2008, some of them quite famous like Fomalhaut b. Parallax measurements showed that it is about 25 light-years away from Earth, and its luminosity is about 16 times greater than the sun. It was the first extrasolar planet captured in visible light. You've successfully subscribed to this newsletter! After first being discovered in 2008, subsequent studies suggested the planet was nothing more than a huge dust cloud. or redistributed. Two scientists recently reported "there could be more than 2,500 zombie-infested planets" in our solar system. The study suggests that the planet, named Fomalhaut b, is a rare and possibly unique object that is completely shrouded by dust. (Image: © ESA/Herschel/PACS/Bram Acke, KU Leuven, Belgium). 'Zombie planet' gets weirder Fomalhaut b is a giant alien planet that is nearly three times the mass of Jupiter. Market data provided by Factset. Impacts from the debris could create a celestial light show on the planet similar to that seen on Jupiter when the comet Shoemaker-Levy 9 battered the gas giant in 1994. October 26, 2012. in Astrophysics, Telescopes. At least one planet orbits this bright star: Fomalhaut b, which was dubbed a "zombie" planet by NASA after its 2005 discovery was debunked as gas, and then proven again in 2012. Zombie-Planet. Astronomers have been gaping at the planet's strange orbit while also wondering why a huge number of comets populate the regions around the star. One way or another, the clues should come out starting in 2032, scientists said. (NASA, ESA, and P. Kalas), Jan. 8, 2013: This diagram shows the orbit of the exoplanet Fomalhaut b as calculated from recent Hubble Space Telescope observations. (Image credit: NASA, ESA, and A. Feild (STScI)), The Brightest Stars in the Sky: A Starry Countdown, revealed Fomalhaut b in three wavelengths of visible light, evidence of a swarm of comets orbiting the star, Space shuttle rocket booster to be part of astronaut memorial at California museum, Samples of asteroid Ryugu arrive in Japan after successful Hayabusa2 capsule landing, NASA's spacecraft spots China's Chang'e 5 lander on the moon, On This Day in Space! In 2032, astronomers expect to solve one riddle that has perplexed scientists since Fomalhaut b's discovery: Is the exoplanet in the plane of the debris disk around its star, or not? It was the first alien planet ever directly imaged in visible light. The planet was imaged by the Hubble Space Telescope orbiting the star inside the outermost debris ring. All rights reserved. The exoplanet, Fomalhaut b, was discovered in 2008 using data from the Hubble Space Telescope. (Image credit: NASA, ESA, and P. Kalas (University of California, Berkeley and SETI Institute)). This illustration shows Fomalhaut b, an exoplanet believed to exist in a ring of dust and rubble surrounding its parent star. Among the several theories to explain Fomalhaut b's extreme orbit is the possibility that the exoplanet had an encounter with another planet, a yet-to-be discovered neighbor. "This could be the planet that gets thrown out.". [Photos of Saturn’s Glorious Rings]. Some scientists said it was likely a dust cloud, a theory they backed up with brightness variations in the discovery team's data. The unbalanced orbit of a so-called "zombie planet" in a dusty star system has astronomers struggling to explain the exoplanet's behavior. In 2004, the object known as Fomalhaut b was a bright spot in the dusty disk surrounding the star, but by 2014, its brightness had faded to below Hubble’s observational limit. and it housed something that was described as the “zombie” planet by NASA. Visit our corporate site. The word "Fomalhaut" derives from an Arabic phrase, Fum Al Hut or "mouth of the fish." The star was listed in the Alfonsine Tables, a medieval listing of stars that was originally written in Spanish. Powered and implemented by FactSet Digital Solutions. By comparison, Earth's sun is believed to be about 4.5 billion years old. "Hot Jupiters get tossed through scattering events, where one planet goes in and one gets thrown out," study co-investigator Mark Clampin, of NASA's Goddard Space Flight Center in Greenbelt, Md., said in a statement. ‘Zombie planet’ gets weirder Fomalhaut b is a giant alien planet that is nearly three times the mass of Jupiter. A set of rings or a nearby shroud of dust and ice could explain why Fomalhaut b appears so bright in visible light images, but is relatively dim in infrared light, according to Kalas. "We are shocked. This material may not be published, broadcast, rewritten, Join our Space Forums to keep talking space on the latest missions, night sky and more! The finding was hotly debated, however. Image released Jan. 8, 2013. Hubble telescope officials said astronomers plan to continue to monitor the Fomalhaut star system over the next few years and decades to see how the star system changes over time. by Mihai Andrei. 'Zombie planet' gets weirder Fomalhaut b is a giant alien planet that is nearly three times the mass of Jupiter. This is not what we expected," said study leader Paul Kalas, an astronomer with the University of California at Berkeley and the SETI Institute in Mountain View, Calif., in a statement Tuesday, Jan. 8.
