The planet was then named Fomalhaut b. Interestingly, this planet also was the first exoplanet to have been imaged by telescopes. When the exoplanet known as Fomalhaut b was first discovered, in the mid 2000s, it made history as one of the first worlds outside of our solar system to be seen directly. In 2014, a planet disappeared from the night sky. Exoplanet Fomalhaut b (also known as Dagon) disappeared before astronomers' eyes after being detected multiple times. What a wonderful discovery, to say the least. The object, called Fomalhaut b, was first announced in 2008, based on data taken in 2004 and 2006. Perhaps, Fomalhaut b disappeared before the Hubble’s eyes, the study authors wrote, because Fomalhaut b was never a planet in the first place; in this scenario, the object astronomers saw in 2004 and 2006 was actually a colossal cloud of icy debris created by a recent, violent collision between two planetary fragments. Astronomer András Gáspár of the University of Arizona told Vice.com that he was looking for something else when he noticed that Fomalhaut b had disappeared from Hubble images in 2014. Then, in 2014, astronomers were stunned to find Fomalhaut b had disappeared. A new theory suggests the … Approximately 25 light-years away from Earth, in the constellation Piscis Austrinus, exists an A-Type main-sequence star called Fomalhaut, and around it, astronomers discovered (and imaged) what seemed to be a massive planet that was designated Fomalhaut b.This world was one of the first exoplanets directly imaged by telescopes. But that was until the planet disappeared into thin air. Perhaps, Fomalhaut b disappeared before the Hubble’s eyes, the study authors wrote, because Fomalhaut b was never a planet in the first place; in this scenario, the object astronomers saw in 2004 and 2006 was actually a colossal cloud of icy debris created by a recent, violent collision between two planetary fragments. The distant world — known as Fomalhaut b and located a neighborly 25 light-years from Earth — was infamous for being one of the first exoplanets ever discovered in visible light by NASA’s Hubble Space Telescope; when astronomers first caught sight of it in 2004 and 2006, the planet appeared as a bright, cool dot moving briskly … Fomalhaut b, one of the first exoplanets discovered in visible light by NASA's Hubble Telescope disappeared from the night sky in 2014, what could have happened to … It was clearly visible in several years of Hubble observations that revealed it was a moving dot. Fomalhaut b, one of the very first exoplanets to be seen directly by telescopes and given the name Dagon, has mysteriously disappeared. A dozen years … First seen in 2004 and again in 2006, the presumed planet – Fomalhaut b – was brighter than would normally be expected and appeared to be following an unusual trajectory just inside a vast cloud of icy debris orbiting the star.
