Exoplanetary Scratchpad

[SysBP Img]

Fomalhaut dust disk is observed in unprecedented detail. It appears reminiscent of the "Eye of Sauron" from the Lord of the Rings films. A planet suspected of causing a sharp gap in the ring was suspected and imaged, becoming the first undisputed exoplanet imaged and the first planet since Neptune to be predicted prior to its discovery. The planet orbits about 115 AU and is between Neptune and 3x Jupiter's mass in an eccentric orbit. Planet b was shown to deviate slightly from its predicted path, stirring up some controversy about the planets' existance. Material surrounding the planet may have been imaged, rather than the planet itself, which some say should bump it off the directly imaged list. Also, the Hubble instrument that detected it is damaged and will not be fixed, making it unobservable for a time.
