The Pacific Ocean teems with phytoplankton along the West Coast of the United States, as captured by the MODIS instrument on NASA’s Aqua satellite. Satellites can track phytoplankton blooms, which occur when these plant-like organisms receive optimal amounts of sunlight and nutrients. Phytoplankton play an important role in removing atmospheric carbon dioxide. Credits: NASA

A team of British and American astronomers used data from several telescopes on the ground and in space — among them the NASA/ESA Hubble Space Telescope — to study the atmosphere of the hot, bloated, Saturn-mass exoplanet WASP-39b, about 700 light-years from Earth. The analysis of the spectrum showed a large amount of water in the exoplanet’s atmosphere — three times more than in Saturn’s atmosphere. WASP-39b is eight times closer to its parent star, WASP-39, than Mercury is to the Sun and it takes only four days to complete an orbit. Credit: NASA, ESA, and G. Bacon (STScI)

Using Hubble and Spitzer, astronomers analyzed the atmosphere of the "hot Saturn" exoplanet WASP-39b, and they captured the most complete spectrum of an exoplanet's atmosphere possible with present-day technology. By dissecting starlight filtering through the planet's atmosphere into its component colors, the team found clear evidence for water vapor. Although the researchers predicted they would see water, they were surprised by how much water they found - three times as much water as Saturn has. This suggests that the planet formed farther out from the star, where it was bombarded by icy material. Credits: Artist's Concept: NASA, ESA, G. Bacon and A. Feild (STScI), and H.
