How the Sahara Desert Went from a Lush, Inhabited Land to a Wasteland

Today, the Sahara Desert, which covers much of North Africa, is regarded as the world’s largest hot desert and the world’s third largest desert, after the deserts of Antarctica and the northern Arctic. However, this desert was once bursting with vegetation, grasslands, lakes and rivers, providing a suitable environment for humans to inhabit. So how did such an enormous transformation happen?

On the southern edge of the world, a waterfall runs red as blood

Antarctica’s Blood Red Waterfall Blood Falls seeps from the end of the Taylor Glacier into Lake Bonney. Peter Rejcek, National Science Foundation One of the world's most extreme deserts might be the last place one would expect to find a waterfall, but in Antarctica's McMurdo Dry Valley, a five-story fall pours slowly out of the Taylor Glacier into Lake Bonney. And it's not just the idea o

Newly discovered super-Earth orbits in and out of its star’s habitable zone. Could life survive its extreme climate?

The climate on such a world must be beyond bizarre. (Image credit: MARK GARLICK/SCIENCE PHOTO) A super-Earth planet that dips in and out of its star's habitable zone has been discovered just 19.7 light-years away. The planet, known as HD 20794d, gets farther out from its star than Mars is from the sun and, on the other end of its orbit, as close as Venus. Each orbit the plan
