This is an artist's concept of that planet, HAT-P-7b. It is a "hot Jupiter" class planet orbiting a star that is much hotter than our sun. Hubble Space Telescope's millionth science observation was trained on this planet to look for the presence of water vapor and to study the planet's atmosphere. NASA, ESA, and G. Bacon (STScI)
