Live coverage: NASA’s Juno spacecraft arrives at Jupiter

Images obtained during the New Horizons spacecraft’s July 14 encounter with Pluto show apparent glacial ice flows wrapping around barrier islands and towering mountain ranges, all under a haze layer suspended up to 100 miles above the distant world’s frozen surface.

In the ten years since its launch from Cape Canaveral, NASA’s Dawn spacecraft has orbited the two largest worlds in the asteroid belt and overcome defective components that threatened to derail the mission on its 4 billion-mile voyage, discovering unexpectedly rich geologic tapestries suggesting both destinations have a watery past.

The dwarf planet Ceres turns out to be a world with untold wonders, with vivid bright spots likely made of dried mineral salts and hazes apparently triggered by daytime heating, drawing a comparison to comets and strikingly differentiating it from neighboring bodies in the asteroid belt.
