A Streamlined Form in Lethe Vallis, Mars


This image shows a portion of Lethe Vallis, an outflow channel that also transported lava. This is one of only a few places on Mars where these pristine-appearing landforms have been identified. The channel formed by catastrophic floods, during which it produced the prominent crater-cored, teardrop-shaped island in the middle. via NASA http://ift.tt/2c6qZ6U

Infrared Echoes of a Black Hole Eating a Star


This illustration shows a glowing stream of material from a star, disrupted as it was being devoured by a supermassive black hole. The feeding black hole is surrounded by a ring of dust. This dust was previously illuminated by flares of high-energy radiation from the feeding black hole, and is now shown re-radiating some of that energy. via NASA http://ift.tt/2cIf9V1
