Time For The Perseid Meteor Shower (or, what do you do with dirty meteor)

Earth is entering a stream of dusty debris from Comet Swift-Tuttle, the source of the annual Perseid meteor shower. Although the shower won't peak until August 11th and 12th, the show is already getting underway.

Big Picture: Lightning


A weather front rolls in from the horizon, storm clouds darken the sky, and (at least 1.3 billion times a year) lightning strikes. Last month, the National Weather Service promoted their Lightning Safety Week, with information designed to call attention to safe practices, helping people avoid lightning strikes which kill an average of 100 people every year. While the exact nature of the initial formation of lightning remains a subject of debate, what is known is that lightning strikes are caused by electrical imbalances present in the clouds. Those imbalances correct themselves suddenly, with an often spectacular light show - which I've tried to show here, with a handful of recent photographs of lightning from around the world.

Big Picture: Dive Right In

As the summer crawls into its later stages, the weather outside is heating up (in the Northern hemisphere at least). Cool waters call out to those who would leap in, momentarily letting gravity have its way with them, pulling them down as they flail, shout or twist. Collected here are a handful of photos of divers around the world, showing their professional artistry, daredevil bravado, or just simple joy as they take the plunge. (35 photos total)
