- Biologists find archaea a true curiosity. They make up one of life’s three main branches. The two better known branches are bacteria and eukaryotes (u KARE ee oatz). That last branch includes animals, plants and fungi. But archaea have remained mysterious. Very little is known about them. In fact, their unique status wasn’t even recognized until relatively recently, in 1977.
- Reed Scherer and Ross Powell have studied mud from all over the world. It is different in each place. Mud from the Sulu Sea near Borneo is as smooth as cream cheese. Mud from Chesapeake Bay, in the mid-Atlantic United States, clings to your skin like peanut butter.
Antarctica’s ice isn’t stuck tight, frozen onto the continent like frigid glue. In many places, liquid water sits between the ice and the ground beneath it. This water forms because heat seeping from inside the Earth gradually melts away the bottom of the ice sheet. Layers of water, thinner than a few stacked coins, melt off of the bottom of the ice each year. This water collects in low places, forming lakes. The water flows from one lake to another. Eventually it empties into the ocean.
The alien invaders arrived quietly. Only one man noticed as they drifted down from the sky.
Visit the beach on a hot afternoon and you may not realize it, but someone — or rather something — is watching from above. If you stand in the right place, the silent watcher’s invisible spotlight will pass right over you, like the spotlight of a police helicopter flitting overhead.
That aerial observer zooming over your head is the Jason-2 satellite. It flies 1,340 kilometers (832 miles) high — as far above the ground as New York City is from Chicago. It travels 25,000 kilometers per hour, 27 times as fast as a commercial jet. And it circles Earth a little over 12 times a day.
The deserts of northwest Utah are wide and flat and dusty. As our car zooms along Highway 80, we see only a few green plants — and one of those is a plastic Christmas tree that someone stood up by the road as a joke.
Richard Brune was pretty dizzy the first time he shot photos while leaning out of a flying airplane.
The plane’s door had been removed so Brune could ride with one leg outside. As the tiny propeller plane zigzagged over the desert, Brune leaned out over empty air. The 80 mile-per-hour headwind pummeled his face. He looked through his camera and snapped pictures of the rocky desert hundreds of feet below.
This stone core was drilled from an ancient seabed that now lies nearly 3 miles underground. The dark color comes from oil left behind by bacteria and animals that lived over 500 million years ago. The white color comes from salt left behind by the sea.
