...wanted to be an exobiologist or a physicist, Johansson has found his dream job developing technologies and solutions unheard of five years ago. He says TV on mobiles requires a new paradigm: "It's a new way of consuming contents. I don't see any limits to what...
Despite Goldin's caution about assuming the existence of Earthlike planets, few astronomers doubt they are out there. If other solar systems do contain Earthlike worlds, says NASA exobiologist Michael Meyer, at least some should fall into the "habitable zone"--the region, governed by a planet's distance from its star, where water is liquid rather than solid or gaseous. "The good news," he says, "is that if our solar system is typical, there's a 50% chance that a planet will be in the right zone...
...landing and the first photographs, none of the Viking scientists seemed particularly disappointed that the pictures showed no obvious signs of life-no lichen, bushes or trees, nothing even remotely resembling an animal or the monsters or little green men beloved by generations of science-fiction writers. Said Exobiologist Carl Sagan: "The pictures do not suggest that the planet is filled, pole to pole, with living things." But, noted Sagan, nothing in the pictures ruled out the existence of life on the planet either. Soffen added that the lander's immediate vicinity held half a dozen niches in which...
Questioned recently about what he thought any strange creature who stepped out of a flying saucer might look like, a celebrated astronomer quipped: "A miniature Carl Sagan." It was not a bad guess. Exobiologist Sagan has long been the prime advocate and perennial gadfly for planetary exploration. He is also this country's leading believer in the possibility of communicating with civilizations on other worlds. With Soviet Astronomer I.S. Shklovskii, Sagan wrote Intelligent Life in the Universe, a recent book that presents the classic argument for the existence of life elsewhere in the universe. As the current director...
That possibility was suggested in a recent study of Titan, the largest of Saturn's ten moons, by a team of Cornell University scientists under Astronomer-Exobiologist Carl Sagan. From infra-red and other telescopic measurements of the satellite, a body as large as the planet Mercury, Sagan and his colleagues conclude that Titan is relatively much warmer (about-100° F.) than previously estimated. It also has a thicker atmosphere than had been suspected and is leaking small quantities of hydrogen gas into space. Pondering these surprising conditions on Titan, the Cornell group has evolved a picture...
