Nearby Star May Have Planetary System Like Ours "Astronomers scanning the skies for far-flung planets have found that the area surrounding a nearby star is very familiar. A report published in the current issue of the Astrophysical Journal suggests that Vega, located 25 light-years away from our sun, may have an orbiting planetary system that is more similar to our own than is any other yet discovered. Mark Wyatt of Edinburgh's Royal Observatory designed a computer model based on observations of a faint disk orbiting Vega, which is three times bigger than the sun and is part of the constellation Lyra, the Harp. Images taken in 1998 by the world's most sensitive submillimeter camera, known as SCUBA, showed extremely cold dust orbiting the star. 'The irregular shape of the disk is the clue that it is likely to contain planets,' Wyatt says. 'Although we can't directly observe the planets, they have created clumps in the disk of dust around the star.' The calculations indicate that the formation of a planet similar in size to Neptune--and orbiting the star at a distance comparable to that between Neptune and the sun--can best explain the observed structure of the disk."...
Christmas Day Mars Landing "It's wintertime in the northern hemisphere of Mars, and a flying saucer is about to land. Back on Earth where it comes from, the craft is known as the Beagle 2, sent to Mars by the European Space Agency in search of life. More accurately, the Beagle 2 will be looking for chemical traces of life--telltale signs that life once existed, or perhaps, exists right now on the red planet. Touchdown is scheduled for Christmas Day 2003. The Beagle 2 will precede two NASA rovers, Spirit and Opportunity, slated to land in January. Named after the ship that carried Charles Darwin, the Beagle 2 is a self-contained laboratory shaped like a saucer, or a pocket watch, about three feet in diameter. Although it carries many powerful scientific tools, it weighs a mere 70 pounds. Being so light and compact, the Beagle 2 was able to hitch a ride to Mars onboard the ESA's Mars Express spacecraft launched last June. While Mars Express, an orbiter, surveys the planet from a few hundred miles up, the Beagle 2 will be able to stick its devices right into Mars, sampling rocks and soil on the surface and below. NASA's Everett Gibson, the interdisciplinary scientist for the Mars Express/Beagle 2 mission, explains: ?We have two [ways] to get samples: a rock abrasion tool, and a burrowing mole." Both are embedded in the Beagle's robotic arm."...
Are You Addicted To Google? An opinion piece from the BBC is wondering if people are addicted to Google. The premise is that Google searches are no longer as relevant as they used to be, and are increasingly cluttered with advertising. However, we all still use it everyday. In many cases, "searching the internet" and "Google" have become synonymous, and so the writer worries that we're all stuck on Google. There's a simple solution, of course: come up with a better search engine. Others are trying, and are probably thrilled with articles like this one.
