High in the Arctic, just below Earth's north polar ice cap, a collaboration of nearly two dozen biologists, geologists, and engineers have embarked on an expedition to Mars. The scientists and researchers are spending two and a half weeks at the Svalbard archipelago in the Arctic Ocean north of Norway. The goal of this annual expedition, called the Arctic Mars Analogue Svalbard Expedition (AMASE), is to characterize the geology, geophysical features, biosignatures, and possible life forms of...

It was a science fiction fantasy come true: Ten years ago this summer, NASA announced the discovery of life on Mars. At a Washington, D.C., news conference, scientists showed magnified pictures of a four-pound Martian meteorite riddled with wormy blobs that looked like bacterial colonies. The researchers explained how they had pried numerous clues from the rock, all strongly supporting their contention that microscopic creatures once occupied its nooks and crannies. It was arguably the space...

When scientists examined a meteorite from Mars under a microscope, they discovered tiny mineral spheres that, some argued, were produced by living organisms. Now, researchers working in the high Arctic have found similar mineral features, produced not by microbes, but by a volcano. The city of Hammerfest lies at the northern tip of Norway, well above the Arctic Circle. If you board a ship heading north from there, just before you reach the polar ice cap you run into a group of islands known...

PASADENA, Calif. -- The current mean temperature on the equator of Mars is a blustery 69 degrees below zero Fahrenheit. Scientists have long thought that the Red Planet was once temperate enough for water to have existed on the surface, and for life to possibly have evolved. But a new study by Caltech and MIT scientists gives this idea the cold shoulder. In the July 22 issue of the journal Science, Caltech graduate student David Shuster and MIT assistant professor Benjamin Weiss (formerly a...

Panspermia -- Panspermia is a theory (more directly described as a hypothesis, as there is no compelling evidence yet available to support or contradict it) that suggests that the seeds of life are prevalent throughout the universe and life on Earth began by such seeds landing on Earth and propagating. The theory has origins in the ideas of Anaxagoras, a Greek philosopher. An important proponent of the theory was the British astronomer Sir Fred Hoyle. There is some evidence to...
