New Horizons spots indicators of a former lake on Pluto
The New Horizons probe is not simply revealing particulars of Pluto’s highest heights… it is also uncovering a few of the dwarf planet’s hidden historical past. NASA has revealed a picture type the spacecraft displaying proof of a former frozen lake. The remnants are comparatively small (20 miles throughout at their widest), however the surrounding channels trace that the lake held liquid nitrogen sooner or later within the distant previous. Whereas we’ll want extra knowledge to attract any agency conclusions, this means that Pluto was significantly livelier “hundreds of thousands or billions” of years in the past — it wasn’t the wasteland it seems to be immediately.
