There are many thousands of volcanoes on the surface of Venus. These volcanoes provide clues into the interior properties of the planet, properties that are otherwise largely inaccessible to scientists at present. In new research, planetrary researchers used the Synthetic Aperture Radar (SAR) imagery from NASA’s Magellan mission to catalog volcanoes across Venus at a global scale. The resulting database contains approximately 85,000 volcanoes, 99%...

A large stream of meltwater (about 5 to 10 m in width) emerges from an upstream supraglacial lake in the Greenlandic ice on July, 21 2012. The darker shapes are minor streams covered by cryoconite (a mix of dust particles, soot, meteorite dust and organic material) which covers the ice sheet. Cracks cutting through the streams are visible. Along these cracks water can flow through, enlarging them and, eventually, generating moulins that can deliver meltwater through the ice.
