Artists from David Bailey to Yinka Shonibare have appropriated the iconic Star Wars headgear for a new exhibition coming soon to London's Saatchi Gallery as part of STRARTA art fair. Art Wars, featuring a tantalising array of variously soup-canned, crocheted and jewel-encrusted helmets, will run …

The Grand Canyon inspires many people to photograph its grandiose scale and scenic landscape, but Sedona-based photographer Rolf Maeder has managed to capture a sight less seen–the Grand Canyon being hit by a spectacular thunderstorm. Being drawn to nature, Maeder originally moved to Sedona 13 …Hiking
Astrophotographer Bob Franke (http://bf-astro.com/) captured this image of stunning barred spiral galaxy Messier 109 from Focal Pointe Observatory in Chino Valley, Arizona. http://oak.ctx.ly/r/8q0k Located about 60 million light-years from Earth in the northern constellation Ursa Major, M 109 or NGC 3992, is a massive galaxy roughly 120,000 light-years in diameter.
NASA’s Hubble Sees a Cosmic Caterpillar - This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast. But the meat of the story is not only what this cosmic caterpillar eats for lunch, but also what's eating it. Harsh winds from extremely bright stars are blasting ultraviolet radiation at this "wanna-be" star and sculpting the gas and dust into its long shape. The culprits are 65 of the hottest, brightest known stars, classified as O-type stars, located 15 light-years away from the knot, towards the right edge of the image. These stars, along with 500 less bright, but still highly luminous B-type stars make up what is called the Cygnus OB2 association. Collectively, the association is thought to have a mass more than 30,000 times that of our sun. The caterpillar-shaped knot, called IRAS 20324+4057, is a protostar in a very early evolutionary stage. It is still in the process of collecting material from an envelope of gas surrounding it. However, that envelope is being eroded by the radiation from Cygnus OB2. Protostars in this region should eventually become young stars with final masses about one to ten times that of our sun, but if the eroding radiation from the nearby bright stars destroys the gas envelope before the protostars finish collecting mass, their final masses may be reduced. Spectroscopic observations of the central star within IRAS 20324+4057 show that it is still collecting material quite heavily from its outer envelope, hoping to bulk up in mass. Only time will tell if the formed star will be a "heavy-weight" or a "light-weight" with respect to its mass.
