Seven Earth-Sized Planets Have Been Spotted Around a Nearby Star

And all of them are in the temperate zone.
In late 2015, in the Chilean desert, astronomers pointed a telescope at a faint, nearby star known as a red dwarf. Amid the star’s dim infrared glow, they spotted periodic dips, a telltale sign that something was passing in front of it, blocking its light every so often. Last summer, the astronomers concluded the mysterious dimming came from three Earth-sized planets—and that they were orbiting in the star’s temperate zone, where temperatures are not too hot, and not too cold, but just right for liquid water, and maybe even life.
