We often think of the Amazon rainforest as a vast expanse of nature untouched by humans. But a new study in Science suggests that's not true -- in fact, today's rainforest is shaped by trees that were cultivated by...
As the light from the star passes through the Earth’s atmosphere some of it is absorbed in the ozone layer. This results in a clear feature that can be seen using telescopes like JWST. Venus, however, has no ozone...
Lightning—one, two, three—and thunder. For centuries, people have estimated the distance of a thunderstorm from the time between lightning and thunder. The greater the time gap between the two signals, the further away the observer is from the location...
Electrically charged volcanic ash short-circuited Earth's atmosphere in 1815, causing global poor weather and Napoleon's defeat, says new research.
Historians know that rainy and muddy conditions helped the Allied army defeat the French Emperor Napoleon Bonaparte at the Battle of...
