WASHINGTON — Astronomers have found what appears to be a gigantic suicidal planet. The odd, fiery planet is so close to its star and so large that it is triggering tremendous plasma tides on the star. Those powerful tides are in turn warping the planet's zippy less-than-a-day orbit around its star. The result: an ever-closer tango of death, with the planet eventually spiraling into the star. It is a slow death. The planet WASP-18b has maybe a million years to live, said planet discoverer Coel Hellier, a professor of astrophysics at Keele University in England. Hellier's report on the suicidal...

We could find planets in other galaxies using today's technology, according to a new simulation. The study gives credence to a tentative detection of a planet in Andromeda, our nearest large galactic neighbour. The idea is to use gravitational microlensing, in which a distant source star is briefly magnified by the gravity of an object passing in front of it. This technique has already found several planets in our galaxy, out to distances of thousands of light years. Extending the method from thousands to millions of light years won't be easy, says Philippe Jetzer of the University of Zürich in...

HATFIELD, England – In the search for Earth-like planets, astronomers zeroed in Tuesday on two places that look awfully familiar to home. One is close to the right size. The other is in the right place. European researchers said they not only found the smallest exoplanet ever, called Gliese 581 e, but realized that a neighboring planet discovered earlier, Gliese 581 d, was in the prime habitable zone for potential life. "The Holy Grail of current exoplanet research is the detection of a rocky, Earth-like planet in the 'habitable zone,'" said Michel Mayor, an astrophysicist at Geneva University in Switzerland....

How kangaroo burgers could save the planet25 December 2008 by Bijal Trivedi COWS, sheep and goats may seem like innocent victims of humanity's appetite for meat, but when it comes to climate change they have a dark secret. Forget cars, planes or even power stations, some of the world's worst greenhouse gas emitters wander idly across rolling pastures chewing the cud, oblivious to the fact that their continuous belching (and to a lesser degree, farting) is warming the planet. Take New Zealand, where 34.2 million sheep, 9.7 million cattle, 1.4 million deer and 155,000 goats emit 48 per cent of...

Something else for Al Gore to worry aboutDecember 19, 2008 letter to the editor I don't know if anyone else has noticed, but I have detected a new crisis that I have named "the daylight change crisis". I first noticed it sometime around the end of June this year. I started paying attention and created computer models and sure enough I was right! We are losing daylight at an astonishing rate. Each day we are losing approximately 2 minutes of day light and my computer models predict total darkness by next July. I have been able to detect this phenomenon...

WASHINGTON (AFP) – NASA's Hubble Space Telescope has discovered both carbon dioxide and carbon monoxide in the atmosphere of a distant planet, in a key step for finding extraterrestrial life, the space agency said Tuesday. Detecting organic compounds that can be a by-product of life processes on an Earth-like body could one day "provide the first evidence of life beyond our planet," NASA said in a statement. The discovery was made on a Jupiter-size planet 63 light years away from Earth that is too hot for life, and is all gas and liquid. "We're not closer to discovering life on...

Planets circle the stars that dot the heavens. Before 1995, we couldn’t have said that with any certainty. Now we know of more than 300 planets orbiting distant stars, and we have a fleet of telescopes looking for them. The ultimate goal is to find another Earth orbiting a star like the Sun, but the quest on the way to that Holy Grail has yielded some strange benchmarks. CoRoT-exo3b, a dense planet orbiting another star COROT-exo-3b compared to Jupiter Meet the planet COROT-exo-3b. It orbits a star slightly larger, hotter, and brighter than the Sun. The star is not an...

Britons should be subjected to random carbon spotchecks and intensive surveillance of their diets, transport and waste disposal habits, says the Government's architecture and design quango in a new report today. The word "monitoring" occurs 19 times in the 32-page publication by the Commission for Architecture and the Built Environment (CABE). If the proposals in the report What Makes An Eco Town?are implemented few aspects of life will go unrecorded. CABE says the strict monitoring is needed to ensure the carbon footprint of the eco-town dwellers remains at one-third of the British average, which is the requirement for what's called...

Astronomers believe they have taken the first amazing photo of a planet around another star like the Sun. The alien world shows up as a tiny orange disk in the image captured by Canadian scientists with a giant telescope in Hawaii. Previous pictures of so-called extrasolar planets orbiting other stars have been painted by artists. The new world was spotted 500 light-years away from Earth in the constellation of Scorpius, the scorpion. Astronomers were puzzled by its distance from its parent star which is 330 times further than we are from the sun. But they carried out detective work with...

Orbit of solar system object SQ372 (blue) compared with the orbits of Neptune Pluto and Sedna (white, green, red). Credit: N. Kaib. Astronomers announced today that a new "minor planet" with an unusual orbit has been found just two billion miles from Earth, closer than Neptune. Using the Sloan Digital Sky Survey, astronomers detected a small, comet-like object called 2006 SQ372, which is likely made of rock and ice. However, its orbit never brings it close enough to the sun for it to develop a tail. Its unusual orbit is an ellipse that is four times longer than it...

Image credit: compiled from NASA public images At times, people still express bemusement, or confusion, that Pluto was reclassified as a "dwarf planet", after having been considered a full-fledged planet for the better part of a century. One thing I always point out to them is that we're discovering more and more roughly Pluto-sized bodies. If we call them all planets, the list of planets would rapidly grow unmanageable! (Do you want to memorize the names of 20 planets? How about 80?) Today the list just got bumped up by one. Meet Makemake, the first body in our solar...

Warmer planet may mean fewer Atlantic hurricanes NewScientist.com news service Mason Inman Contrary to the widespread view that a warming world will bring more hurricanes, a controversial new study suggests the number of cyclones could actually drop in the North Atlantic. Hurricanes have become a lightning rod for arguments over what global warming might have in store. Most researchers agree that, since 1950, the number of hurricanes forming over the Atlantic has increased, and that since at least since 1980, they have become fiercer. Many studies have blamed the increase in Atlantic hurricanes on increasing sea-surface temperatures, which fuel the...

Hollywood—In what could only be referred to as a historic event, Hollywood is shutting down its doors to save “Mother Earth.” The move comes after years of trying to reach an unsympathetic Bush administration, and decades of attempts at inculcating the American populous. The historic decision—based largely on the overwhelming evidence of the plight of polar bears, spotted owls and tropical insects—has forced the inevitable activist outcome, an outcome designed to promote a greener planet. Over the last year, article after article has emerged, detailing the destruction to the planet via one species or another. The evidence has only fallen...

Earth Day TipsTuesday, Apr 22, 2008 @05:45pm CST Experts say Earth Day should be more than a once-a-year observance. Anne Reichman with Earth911 says it's a good time to examine your lifestyle and find ways to conserve. She says the average American generates about 4.3 pounds of garbage every day. Reichman says this number can be reduced drastically if everyone makes an effort to cut back. She says bringing your own coffee cup or water bottle to reuse at work and starting a recycling program at home or at the office are good places to start. Reichman also recommends having...

MADRID (AFP) - Spanish astronomers Wednesday announced the discovery of the smallest planet discovered to date outside the solar system, located 30 light years from earth. The planet, "GJ 436T", was detected through a new technique which "will allow us to discover in less than 10 years the first planet resembling earth in terms of mass and orbit," said Ignasi Ribas of Spain's CSIC scientific research institute. It was discovered by a team led by Ribas through its gravitational pull on other planets already discovered around the same star in the constellation of Leo. "GJ 436T" has a mass five...

It may sound like science fiction, but it’s only a matter of time before the world’s militaries learn to wield the planet itself as a weapon. Preventing global warming from becoming a planetary catastrophe may take something even more drastic than renewable energy, superefficient urban design, and global carbon taxes. Such innovations remain critical, and yet disruptions to the Earth’s climate could overwhelm these relatively slow, incremental changes in how we live. As reports of faster-than-expected climate changes mount, a growing number of experts worry that we might ultimately be forced to try something quite radical: geoengineering. Geoengineering involves humans...

WASHINGTON - The first pictures from the unseen side of Mercury reveal the wrinkles of a shrinking, aging planet with scars from volcanic eruptions and a birthmark shaped like a spider. Some of the 1,213 photos taken by NASA's Messenger probe and unveiled Wednesday help support the case that ancient volcanoes dot Mercury and that it is shrinking as it gets older, forming wrinkle-like ridges. But other images are surprising and puzzling. The spidery shape captured in a photo is "unlike anything we've seen anywhere in the solar system," said mission chief scientist Sean Solomon of the Carnegie Institution of...

Deadly Ozone From Drive-Thru ManiaBy Kellie Hastings Edmonton's drive-thrus contribute 750 tons of Green House Gases into the atmosphere in one month alone. In one year that's 9000 tons from one city! Is it possible that the time has come for us to re-evaluate the importance of what we're actually breathing in here? Should we re-consider the consequences of this unnecessary convenience just to eliminate that simple walk? This alarming discovery was given immediate attention by CTV news and revealing these startling estimated statistics May 30 2007 the source came from the University of Calgary.

PARIS (AFP) - A kilogram (2.2 pounds) of beef causes more greenhouse-gas and other pollution than driving for three hours while leaving all the lights on back home, according to a Japanese study. A team led by Akifumi Ogino of the National Institute of Livestock and Grassland Science in Tsukuba, calculated the environmental cost of raising cattle through conventional farming, slaughtering the animal and distributing the meat, New Scientist reports in next Saturday's issue. Producing a kilo (2.2 pounds) of beef causes the equivalent of 36.4 kilos (80.08 pounds) in carbon dioxide (CO2), the principal greenhouse gas, Ogino found. Most...

PARIS (AFP) - Astronomers on Wednesday announced they had spotted the first planet beyond the Solar System that has water, the precious ingredient for life. The watery world, though, is far beyond the reach of our puny chemically-powered rockets -- and in any case is quite uninhabitable. It is made of gas rather than rock and its atmosphere reaches temperatures hot enough to melt steel, which means the water exists only as superheated steam. The find, named HD189733b, is about 15 percent bigger than our Jupiter and orbits a star in the constellation of Vulpecula the Fox, according to a...

Astronomers have found the most Earth-like planet outside our Solar System to date, a world which could have water running on its surface. The planet orbits the faint star Gliese 581, which is 20.5 light-years away in the constellation Libra. Scientists made the discovery using the Eso 3.6m Telescope in Chile. They say the benign temperatures on the planet mean any water there could exist in liquid form, and this raises the chances it could also harbour life. "We have estimated that the mean temperature of this 'super-Earth' lies between 0 and 40 degrees Celsius, and water would thus be...

WASHINGTON - For the first time astronomers have discovered a planet outside our solar system that is potentially habitable, with Earth-like temperatures, a find researchers described Tuesday as a big step in the search for "life in the universe." The planet is just the right size, might have water in liquid form, and in galactic terms is relatively nearby at 120 trillion miles away. But the star it closely orbits, known as a "red dwarf," is much smaller, dimmer and cooler than our sun. There's still a lot that is unknown about the new planet, which could be deemed inhospitable...

Munich, April 24: An international team of astronomers from Switzerland, France and Portugal have discovered the most Earth-like planet outside our Solar System to date. The planet has a radius only 50 percent larger than Earth and is very likely to contain liquid water on its surface. The research team used the European Southern Observatory’s (ESO’s) 3.6-m telescope to discover the super-Earth, which has a mass about five times that of the Earth and orbits a red dwarf already known to harbour a Neptune-mass planet. Astronomers believe there is a strong possibility in the presence of a third planet with...

Astronomers have detected water in the atmosphere of a planet outside our solar system for the first time. The finding, to be detailed in an upcoming issue of Astrophysical Journal, confirms previous theories that say water vapor should be present in the atmospheres of nearly all the known extrasolar planets. Even hot Jupiters, gaseous planets that orbit closer to their stars than Mercury to our Sun, are thought to have water. The discovery, announced today, means one of the most crucial elements for life as we know it can exist around planets orbiting other stars. 'We know that water vapor...

Nasa release on the topography of the south polar region of Mars Scientists studying pictures from Nasa's Odyssey spacecraft have spotted what they think may be seven caves on the surface of Mars.The candidate caves are on the flanks of the Arsia Mons volcano and are of sufficient depth their floors mostly cannot be seen through the opening. Details were presented here at the Lunar and Planetary Science Conference in Houston, Texas. Temperature data from Mars Odyssey's Themis instrument support the idea. The authors say that the possible discovery of caves on the Red Planet is significant. The caves...

Love thy planet -------------------------------------------------------------------------------- Posted: December 4, 2006 1:00 a.m. Eastern Recently Rev. Joel Hunter, the elected president of the famed Christian Coalition, founded by Pat Robertson, stepped down due to what appears to be irreconcilable differences over how to use the organization's political and real capital. Does the organization, as it has in the past, continue to focus on pet personal piety issues such as same-sex marriage, or does it take a completely new tack and resurrect the social justice roots of Christianity? Rev. Hunter wanted to fix the Christian Coalition's massive energy beam on the environment — which...

Pluto has been given a new name to reflect its new status as a dwarf planet. On Sept. 7, the former 9th planet was assigned the asteroid number 134340 by the Minor Planet Center (MPC), the official organization responsible for collecting data about asteroids and comets in our solar system. The move reinforces the International Astronomical Union's (IAU) recent decision to strip Pluto of its planethood and places it in the same category as other small solar-system bodies with accurately known orbits. Pluto's companion satellites, Charon, Nix and Hydra are considered part of the same system and will not be...

WASHINGTON - The largest planet ever found orbiting another star is so puffy it would float on water, astronomers said Thursday. The newly discovered planet, dubbed HAT-P-1, is both the largest and least dense of the nearly 200 worlds astronomers have found outside our own solar system. HAT-P-1 orbits one of a pair of stars in the constellation Lacerta, about 450 light-years from Earth. "This new planet, if you could imagine putting it in a cosmic water glass, it would float," said Robert Noyes, a research astrophysicist with the Smithsonian Astrophysical Observatory. HAT-P-1 is an oddball planet, since it orbits...

A distant, icy rock whose discovery shook up the solar system and led to Pluto's planetary demise has been given a name: Eris. The christening of Eris, named after the Greek goddess of chaos and strife, was announced by the International Astronomical Union on Wednesday. Weeks earlier, the professional astronomers' group stripped Pluto of its planethood under new controversial guidelines. Since its discovery last year, Eris, which had been known as 2003 UB313, ignited a debate about what constitutes a planet. Astronomers were split over how to classify the object because there was no universal definition. Some argued it should...

Not for the first time, but with new urgency in 2006, the International Astronomical Union (IAU) impaneled a committee to define both the word "planet" and the status of Pluto. Our committee -- seven in number, like the planets of old -- met at the Paris Observatory in late June and reached a unanimous agreement. In short: A planet is a body in orbit around a star (as opposed to orbiting another planet) and big enough for gravity to make it round. The full text of our proposed definition is being released today, to be discussed by astronomers from around...
