The Revival of  a 'Dead' Exoplanet: Zombie Fomalhaut B

  A second look at data from NASA’s Hubble Space Telescope is reanimating the claim that the nearby star Fomalhaut hosts a massive exoplanet. The study suggests that the planet, named Fomalhaut b, is a rare and possibly unique object that is completely shrouded by dust. Fomalhaut, the brightest star in the constellation Piscis Austrinus. Image [continue reading]
