NASA Puts Next-Gen Exoplanet-Imaging Technology to the Test

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) JPL scientist Vanessa Bailey stands behind the Nancy Grace Roman Coronagraph , which has been undergoing testing at JPL. About the size of a baby grand piano, the Coronagraph is designed to block starlight and allow scientists to see the faint light from planets outside our solar system. A cutting-edge tool to view planets outside our solar system has passed two key tests ahead of its launch as part of the agency’s Roman Space Telescope by 2027. The Coronagraph…

NASA’s Hubble Finds Water Vapor in Small Exoplanet’s Atmosphere

5 min read NASA’s Hubble Finds Water Vapor in Small Exoplanet’s Atmosphere This is an artist’s concept of the exoplanet GJ 9827d, the smallest exoplanet where water vapor has been detected in the atmosphere. The planet could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy. With only about twice Earth’s diameter, the planet orbits the red dwarf star GJ 9827. Two inner planets in the system are on the left. The background stars are plotted as they would be seen to the unaided eye looking…
