The announcement was made just days ago. Co-discoverer Michael Endl tells us about the discovery of a roughly Earth-mass planet orbiting in the habitable zone of the closest star to our own. Juno has made its first science flyby of Jupiter. Emily Lakdawalla gives us an early report. Are you ready for the first interplanetary Olympics? Bruce and Mat review the listener-submitted out-of-this-world sports on What’s Up. Bill Nye is away this week.

Artist's impression of the surface of planet Proxima Centauri b
This artist’s impression shows a view of the surface of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System. The double star Alpha Centauri AB also appears in the image to the upper-right of Proxima itself. Proxima b is a little more massive than the Earth and orbits in the habitable zone around Proxima Centauri, where the temperature is suitable for liquid water to exist on its surface.
