we live in an amazing planetary system. from the yawning valles marineris on mars and the subsurface ocean hiding beneath the ice crust of jupiter’s moon europa, to the eerily earth-like terrain of saturn’s moon titan, the solar system brims with wonders. and let’s not forget the sun, with its mysteriously hot corona and its solar flares.
here you’ll find the latest news from our ongoing exploration of the solar system. whether it be stunning pictures from nasa’s curiosity rover or new revelations about planets’ history and formation, we bring you authoritative reports on the coolest and most important developments in planetary science and heliophysics.
