Fomalhaut b, a directly imaged exoplanet This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. The Hubble images were taken with the Space Telescope Imaging Spectrograph in 2010 and 2012. NASA, ESA, and P. Kalas
