Photo: Screen capture from video. Like many youngsters, and those young at heart, seven-year-old Max Geissbuhler and his dad dreamed of visiting space -- and armed with just a weather balloon, video camera, and an iPhone, in a way they did just that. The father and son team from Brooklyn managed to send their homemade spacecraft up nearly 19 miles, high into the stratosphere, bringing back perhaps the most impressive amateur space footage ever.

3 August 2011 Last updated at 08:38 GMT By Jason Palmer Science and technology reporter, BBC News The team has located possible "bubble universe" evidence in WMAP data The idea that other universes - as well as our own - lie within "bubbles" of space and time has received a boost. Studies of the low-temperature glow left from the Big Bang suggest that several of these "bubble universes" may have left marks on our own. This "multiverse" idea is popular in modern physics, but experimental tests have been hard to come by.
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2011 March 25 Explanation: Intense auroral activity flooded the night with shimmering colors on February 24, captured here from a lodge near the city of Yellowknife in northern Canada. The stunning sequence (left to right) of three all-sky exposures, taken at 30 second intervals, shows rapid changes in dancing curtains of northern lights against a starry background. What makes the northern lights dance?

Forget about inclined planes and pulleys. In this series from the PBS program NOVA, physics is presented as an exotic, mind-bending realm. The Fabric of the Cosmos , first broadcast in November, follows up on the 2003 Peabody Award-winning The Elegant Universe . Both series are adapted from the best-selling books of host Brian Greene , a mathematician and physicist at Columbia University. Like the earlier series, which was centered around String Theory, The Fabric of the Cosmos deals with ideas that are on the cutting edge of scientific theory.
The Origin, History, Evolution & Future of the Universe
Dark Matter & Dark Energy
Simulations of the Universe on the largest scales show an unexpected resemblance to nerve cells in the human brain, with galaxy clusters playing the role of the cell body and thinner filaments of matter linking them like axons. Galaxy surveys (such as the Sloan Digital Sky Survey, or SDSS ) show that galaxies do cluster like our simulations predict. But the filaments that should connect them have been harder to find. Most of the mass in the Universe is dark matter—material that neither emits nor absorbs light—and filaments are predicted to be mostly dark matter: no galaxies, little hot gas. Einstein's general theory of relativity, however, tells us mass affects the path of light, and a group of astronomers have identified a dark matter filament by measuring this effect.
Aug 21, 2008 Holes in Space In the gravitational model of the universe, "dark matter" attraction pulls galaxies into filaments. Birkeland currents could be a better explanation. A recent announcement in the astronomical journals and popular press identifies an area of space as a " huge hole " completely empty of matter and energy. "Not only has no one ever found a void this big, but we never even expected to find one this size," said researcher Lawrence Rudnick of the University of Minnesota.
John Archibald Wheeler, high priest of quantum mysteries, suspects thatreality exists not because of physical particles but rather because of the actof observing the universe. "Information may not be just what we learn about the world," he says. "It may be what makes the world." The world seems to be putting itself together piece by piece on thisdamp gray morning along the coast of Maine.
May 27th, 2011: the last spacewalk for NASA’s Endeavour astronauts. Here, a fish-eye lens attached to an electronic still camera was used to capture this image of NASA astronaut Michael Fincke (top center) during the mission’s fourth session of extravehicular activity (EVA) as construction and maintenance continued on the International Space Station. Photo #1 by NASA A bright sun, a portion of the International Space Station and Earth’s horizon are featured in this image photographed by a spacewalker during the STS-134 mission. Photo #2 by NASA
Atmospheres can refract light, as light changes angle depending on the medium it passes through. Gravity actually bends light, as the space the light travels through is warped, in exactly the same way it bends matter. To be specific, it doesn't bend the light itself, but the space if moves through. So if the space around an object is curved toward it, that object would cause the paths of comets, atoms, particles, and photons to bend slightly toward it too.
Camping in Utah's sparsely populated desert areas provides opportunities to view the night skies with little light pollution. This view of the summer night sky was captured from the dry (well, muddy) bed of Sevier Lake in Utah's West Desert. The links in the bottom left corner provide access to a view with several constellations outlined. The winter night sky as seen from the Grand Staircase-Escalante National Monument brings with it the prominent constellation Orion. - Martin van Hemert <p style="text-align:right;color:#A8A8A8"></p>
