MIT researchers have discovered four new exoplanets orbiting a sun-like star just over 200 light-years from Earth. Because of the diversity of these planets and brightness of their star, this system could be an ideal target for atmospheric characterization with NASA’s upcoming James Webb Space Telescope. Tansu Daylan, a postdoc at the MIT Kavli Institute for Astrophysics and Space Research, led the study published in The Astronomical Journal on Jan. 25. With further study, says Daylan, this bright star and its many planets could be critical to understanding how planets…
