Scientists Exiling Robots to Lonely, Desolate Work Camps


When scientists need to research a frigid, barren wasteland so inhospitable that humans stand no chance of survival, what do they do? Dispatch enslaved, persecuted, and voiceless robots, of course. With its excessively dry climate, low wind, and low atmospheric turbulence, Antarctica provides ideal star-gazing opportunities, but its negative-130-degree temperatures and geographical inaccessibility obviously make the job incredibly difficult for people.

Last year, under the leadership of the Polar Research Institute of China, scientists in Antarctica constructed the automated PLATeau Observatory (PLATO), a research station equipped with seven telescopes. Because of the success of PLATO, the National Science Foundation is constructing another unmanned, robot-controlled astronomical viewing station in an area known as Ridge A.

14-Year-Old Discovers Rare Supernova



If nine-year-olds can work for Microsoft and become feared professional gamers, why can't a 14-year-old leave her mark on the world of astronomy? Oh, wait, she can -- as proven by Caroline Moore, a student from upstate New York who discovered an exploding star that occurred in a galaxy roughly 70 million light years away.

All the way back in November, Caroline spotted the faint glow in the sky with nothing more than a low-powered telescope. Word got out and after months of monitoring at some of the most advanced installations in the world, astronomers decided that the explosion was a curiously small supernova.

Dutch School Teacher Finds New Intergalactic Object

Dutch School Teacher Finds New Intergalactic Object
It's called Hanny's Voorwerp, after its discoverer Hanny Van Arkel and the Dutch word for object. Van Arkel noticed the green blob while using the Web site Galaxy Zoo, where volunteers pour over images of galaxies and other cosmic objects and help scientists categorize them.

Scientists believe that the Voorwerp was lit up by a powerful quasar (a massive black hole that blasts light and radio waves into space) that has since gone dark, leaving behind the light echo that keeps the gas cloud glowing (a result of the light having to travel insanely long distances to the Voorwerp).

The object had been categorized before, but its significance was only noticed when the 25-year-old amateur astronomer Van Arkel realized that it did not match any of the known galaxy types in the Galaxy Zoo catalog. Hanny's Voorwerp is the only object of its type ever discovered. Scientists are planning more in-depth analysis with the Isaac Newton Group of telescopes in La Palma, Spain. [Source: BBC]

Astronomers Find Solar System Like Our Own

Astronomers Find Solar System Like Our Own
Last week, astronomers announced that they had discovered a solar system that was "like our own" about 5,000 light years away. And, of course, by like our own they mean that it might be... potentially... kinda-sorta... similar in some respects... to our own solar system.

The new system has a red star at the center about half the mass of our own sun and is orbited by at least two planets. The two planets discovered are large gas giants, but unlike previously discovered planetary systems, they're orbiting farther out from their star, allowing room for potential smaller rocky planets to exist.

One planet is about two-thirds the size the Jupiter, while the second is roughly 90 percent of the size of Saturn. Both planets in the new solar system orbit at a much shorter distance from their sun than either Saturn or Jupiter orbit from our sun.

The most amazing part of the discovery, however,is that some of the most important data was produced by a pair of amateur astronomers from Auckland, New Zealand. Jennie McCormick and Grant Christie were able to calculate not only the mass of the star and the planets, but also an approximation of their orbits -- all by using a simple 10-inch Meade telescope in Ms. McCormick's shed.

Until now. all work on extra-solar planets was done at massive multi-million dollar telescopes, which just proves that even expensive astronomical equipment is not immune to the democratization of resources that advances in technology have aleady brought to music-, film-, and video-creation, among other previously expensive and hard-to-break-into endeavors.

Possible Earth II Found


As recently as 1995, we had no evidence that planets existed around other stars. It was just a logical assumption that extra-solar planets must exist. Since then, we have found hundreds of planets orbiting other stars, most of them gas giants like Jupiter. But recently a smaller planet has been found orbiting Gliese 581 about 20 light-years away. What makes this planet even more interesting is that it orbits its ref dwarf parent star at a distance that scientist theorize could allow for a temperate climate. The planet's surface temperatures are estimated at between 0 and 40 degrees Celsius which is warm enough to support liquid water.

The planet has roughly five times the mass of the earth, making it the smallest planet found outside our solar system. Astronomers believe that the planet is either very rocky or completely covered in oceans. While there is no direct evidence as to the make up of the atmosphere or even if liquid water is actually present on the surface, the mere possibility is exciting since water is essential for life (as we know it) to thrive. This is the third planet found orbiting Gliese 581.

    8.5 out of 10

    Apple iMac (24-inch, 2.8GHz)
    A minor specification update results in some significant performance gains; graphics upgrade an option on this 24-inch model; sleek, polished design didn't receive an update, but we won't start clamoring for a new design until the current one is at least 12 months old. Full Review

    8.4 out of 10

    Apple iMac (27-inch, 3.06Hz Intel Core 2 Duo, ATI Radeon HD 4670, Fall 2009)
    Largest display among all-in-ones; fast dual-core CPU makes up for lack of quad-core (mostly); finally has an SD card slot; wireless mouse and keyboard; Mini DisplayPort input ripe with possibility. Full Review
