By Will Dunham WASHINGTON (Reuters) - Tiny bubbles that formed inside volcanic rock 2.7 billion years ago are providing big insights into the conditions on primordial Earth. Scientists said an analysis of gas bubbles trapped in ancient basalt rock that formed from ancient lava flows in western Australia showed the planet back then possessed a much thinner atmosphere, with air pressure half of what it is today.

Lake Maracaibo in Venezuela has a new claim to fame: This large bay has been revealed as the lightning capital of the world, with storms lighting up the skies almost 300 nights each year, according to a NASA study. The largest lake in South America, Lake Maracaibo sits along the northern Andes Mountains, where the mountains form a natural barrier, pushing air up and mixing it with warm, moist air above the lake to create nocturnal thunderstorms.
