NASA har tagit fram posters med framtidsvisioner. Fin färg och form med bra skärpa.

”Twice as big in volume as the Earth, HD 40307 g straddles the line between "Super-Earth" and "mini-Neptune" and scientists aren't sure if it has a rocky surface or one that's buried beneath thick layers of gas and ice. One thing is certain though: at eight time the Earth's mass, its gravitational pull is much, much stronger.”
