A Smoggy Day on Venus
Before telling where I've gone this week, there is news from Venus. ESA's Venus Monitoring Camera has found mysterious hazes that appear and disappear in a few days. The hazes are composed of sulfur dioxide and water vapour, source unknown. Like the polar hot spots seen on other worlds, the haze begins at the South Pole and moves outward.
In the islands we learn to recognise volcanic activity when we see it. Kilauea Volcano issues water vapour from the Steaming Cliffs, and sulfur from vents. These hazy clouds probably issue from Venus' interior. We have previously seen geysers on Enceladus' South Pole and hydrocarbons gushing from Titan. These diverse worlds could all have internal heat powered by central Black Holes.
I'm staying at a place known for smog and haze, but more about that soon. More Space news at the new Carnival of Space!
