A new discovery by NASA’s Spitzer Space Telescope has revealed seven Earth-sized planets around the M dwarf star known as TRAPPIST-1.
Three of them lie in what is known as the habitable zone -- where there is the potential for liquid water. It is the largest batch of Earth-sized worlds ever discovered in the habitable zone of a single star. While we don’t know if there is life on the TRAPPIST-1 planets, we do know that any life discovered there would likely be very different from life on Earth.
It would have to survive the stormy solar flares of an M dwarf, adapt to a planet that might have extreme temperature swings, and thrive in red and infrared light.
All seven worlds are early ambassadors of a new generation of planet-hunting targets that promise a new vision of the word “habitable.”
