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 … What a wonderful discovery, to say the least. 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 … It was clearly visible in several years of Hubble observations that revealed it was a moving dot. A new theory suggests the … The planet was then named Fomalhaut b. Interestingly, this planet also was the first exoplanet to have been imaged by telescopes. Fomalhaut b, one of the very first exoplanets to be seen directly by telescopes and given the name Dagon, has mysteriously disappeared. 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. 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. 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. In 2014, a planet disappeared from the night sky. A dozen years … The object, called Fomalhaut b, was first announced in 2008, based on data taken in 2004 and 2006. Then, in 2014, astronomers were stunned to find Fomalhaut b had disappeared. But that was until the planet disappeared into thin air. 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. 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. Exoplanet Fomalhaut b (also known as Dagon) disappeared before astronomers' eyes after being detected multiple times. 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.
