Red dwarf stars appear to flare preferentially at high latitudes, which might keep their exoplanets habitable instead of hellish. The post Red Dwarfs Aren’t So Bad (For Planets) After All appeared first on Sky & Telescope.
Read MoreA Pileup of Perpendicular Planets
In some planetary systems, the direction that a star spins and the direction its planets orbit don’t always line up. A new study explores what we can learn from these nonconformists. The post A Pileup of Perpendicular Planets appeared first on Sky & Telescope.
