A possible ice-cold Earth discovered in the archives of the retired Kepler Space Telescope

Scientists continue to mine data gathered by NASA's Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the latest: a possible rocky planet slightly larger than Earth, orbiting a sun-like star about 146 light-years away. The candidate planet, HD 137010 b, might be remarkably similar to Earth, but it has one potentially big difference: It could be colder than perpetually frozen Mars.
