There is amazing detail showing these crazy islands embedded in the middle of a potentially magma lake rimmed with hot lava,” he added. “The specular reflection our instruments recorded of the lake suggests parts of Io’s surface are as smooth as glass, reminiscent of volcanically created obsidian glass on Earth.”Bolton announced the findings on April 16 at the European Geophysical Union General Assembly in Vienna. The new data is painting a clearer portrait of Io, which has intrigued scientists for centuries.“Other than the Earth, it’s the only place that we see active magma volcanoes going on in our solar sys …
