		<description><![CDATA[Theorists were talking about them as early as the 1960’s, but the first confirmed observation of a brown dwarf, an object that’s more than a planet but not quite a star, didn’t come until 1994. Since then, astronomers have been making up for lost time, trying their best to understand these cosmic oddballs. Now a team based at the University of Arizona has used not one but two space telescopes to reveal something in a brown dwarf lying 30 light years from Earth that we usually think of as very much a terrestrial phenomenon: weather patterns — including clouds most likely made from particles of iron and sand. (Photos: Scenes From the International Space Station) The dwarf in question is named (believe it or not) 2MASS J22282889-431026, and the observations, reported in Astrophysical Journal Letters, show an atmosphere in no small amount of turmoil. That’s not surprising: the planet Jupiter, the closest thing in our own Solar System to a brown dwarf, has clouds of ammonia, water vapor and various hydrocarbons, driven around the planet by powerful winds and sucked into gigantic storms like the Great Red Spot that can last for centuries. (MORE: Stellar Dust Rings Could Promise Big Things) But 2MASS J22282889-431026 is more than just a Jupiter — it&#8217;s probably 30 times more massive, which is close to half as big as it would have to be to burst into the nuclear reactions that would qualify it as a star. Still, at perhaps 1,300°F (700°C) on its gaseous “surface,” and even toastier deep inside thanks to heat left over from its formation billions of years ago, it’s got enough energy to get its atmosphere roiling nicely — and by using the powerful tag team of the Hubble and Spitzer space telescopes, lead author Esther Buenzli and her colleagues managed to get an unprecedentedly good look at the brown dwarf’s infrared glow. That, in turn, provided them with a glimpse inside. “This is the first time,” she says, “that we’re starting to get a three-dimensional look at its atmosphere.”<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=science.time.com&#038;blog=13785469&#038;post=12948&#038;subd=timeecocentric&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[High winds can be enough of a problem here on Earth — a fact we&#8217;re learning anew as Hurricane Isaac fades into history and Hurricane Leslie stirs to life. As it happens, a stiff wind in space shouldn’t be overlooked either. So-called galactic winds, which are primarily photons shed from massive stars but sometimes also include thermal energy from exploding stars, are basically interstellar housekeepers. They careen outward from a galaxy’s core, applying pressure to dust molecules which in turn sweep gas and debris to the galaxy’s border — but most of the time no farther. The winds from massive stars are simply not powerful enough to push any harder, unless they have help from black holes, the suspected source of such prodigious energy. Or that&#8217;s the way it always seemed. But astrophysicists have just discovered evidence that intense star formation in nearly two dozen small, dense galaxies is fueling galactic winds so fierce that they’re reaching escape velocity, driving free-floating dust and gas completely out into intergalactic space. The result of such a thorough housecleaning: the winds are stripping the galaxies of their fuel for producing new generations of stars. (PHOTOS: Spinning in the Heavens — Spiral Galaxies) “Usually gas gets blown out but then falls back into a galaxy, where it can form more stars,” says Aleksandar Diamond-Stanic, a fellow at the University of California, San Diego, and the lead author of a paper on the winds recently published in Astrophysical Journal Letters. “In these cases, the gas gets blown out and never comes back.” That takes a lot of oomph. If you think Isaac’s 80-mph wind speeds were bad, try 1,500 miles — per second. That’s the velocity researchers clocked within four galaxies, each of them several billion light years from Earth. Overall, they found 14 galaxies with outflow velocities topping 621 miles (1,000 km) per second, fast enough to escape most galaxies’ gravitational pull. To figure out what was going on, Diamond-Stanic and his colleagues had to become galactic storm chasers, attempting to answer the obvious question:<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=science.time.com&#038;blog=13785469&#038;post=10489&#038;subd=timeecocentric&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Dark matter and Big Bangs may not be easy to visualize, but planets orbiting twin stars is something many of us have envisioned from the moment the London Symphony Orchestra accompanied Luke Skywalker’s wistful gaze at Tatooine’s binary suns.  The one hitch: it was pure imagination. (Sorry, Star Wars fans.) Until recently, astronomers had little evidence suggesting such ornate cosmic architectures could actually exist in this galaxy, if not one far, far away. Now new research into a tantalizing binary star system may trump an entire generation’s collective imagination.  Using information collected by NASA’s Kepler Space Telescope, astronomers have discovered the equivalent of a cosmic poker hand: a pair of planets orbiting a pair of suns.  And there’s even a chance for a full house since the researchers have also found another object that, while still unconfirmed, may turn out to be a third planet orbiting the same two stars. “This shows us that close binaries can host full-fledged planetary systems,” says Jerome Orosz, an astronomer at San Diego State University and the lead author of a paper on the new binary star system, labeled Kepler-47, that was just published in the journal Science.  “If we get more data that confirms a third planet, then the sky’s the limit.” (MORE: The Great, Exploding Monty Python Star) Until now, astronomers were aware of about a dozen examples of single planets that are gravitationally tied to “eclipsing binary” stars—stars orbiting each other, with one occasionally blocking the other’s light when viewed from Earth.  In addition, there are another four recently discovered cases where single planets are orbiting “close binaries,” meaning stars that are no more than a few of our sun’s diameter apart—equivalent to the neighboring cubicle in the galactic office.  But Kepler-47 marks the first time astronomers have found evidence that more than one world can orbit the same close binary star system. “There are lots of binary stars with planets, but the stars are widely separated,” says Orosz. “Imagine the sun and then a companion star where Pluto is, or<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=science.time.com&#038;blog=13785469&#038;post=10346&#038;subd=timeecocentric&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>
