It’s a rare thing when every single part of an astronomy news story is super cool , but here we are. You’ll want to stick around for all of this. A telescope the size of the planet has observed a binary red dwarf star system for 14 years, nailing down the positions of the two stars to incredible accuracy, and happened to discover a planet more massive than Jupiter orbiting one of them in a plane hugely tilted to the orbits of the stars around each other. Oh, yes . This is my kind of story [ link to paper ]. The star system is called GJ 896, and it’s a pair of low-mass red dwarfs 20.37 light-years from Earth — and yes, as I’ll get to, the distance is known that accurately. The more massive of the two, GJ 896A, is about 0.44 times the mass of the Sun, and its companion star, GJ 896B, is much smaller at 0.165 solar masses. So both are dinky.…
