Citizen Science - CosmoQuest Today, scientific discoveries ranging from finding new planets orbiting alien stars to finding light echoes from quasars are all being made by everyday people working as citizen scientists. This isn't a new phenomenon - the planet Uranus was found by composer turned astronomer William Herschel - and throughout history, people like you have transformed science just by asking "What is that?"

Top 25 things NASA has done | National Aeronautics And Space Administration celebrates 50th anniversary
The International Space Station (ISS) is a habitable satellite that was launched on October 31 2000 and has had continued human occupation ever since, the longest on record. It's an observatory and research laboratory in low Earth orbit with crew conducting experiments in Biology, Physics and Astronomy, amongst other things. The station orbits the Earth every 90 minutes, and in 2010 it had racked up almost 60,000 orbits, accruing a whopping 1.5 billion miles. To give you an idea of its size, in total it's about the area of a U.S. football field, and weighs over 400,000 kilograms. You can see the ISS without a telescope; the best time is the few hours after sunset or before sunrise. If you want to take a look at what it's doing and have a sneaky peek at the crew whilst they're on duty, check out the live ISS stream here! Live From The International Space Station!
Well, in a technical sense they all are. I don't think any of these pictures (with the possible exception of the one of the Pacific taken from the ISS) are in true color, so they've all been color-balanced to appear as they would under "normal" conditions. Other than that, nope. A gallery of sublime photographs from across our solar system
These incredible photos from the International Space Station make Earth look like a video game That general glow you're seeing from Earth is actually a naturally occurring phenomenon called "airglow". Airglow is unrelated to human activity, and is the result of excitement of atoms in the atmosphere, leading to light emission. Airglow is responsible for a large majority of the nighttime light (moonless night) and is estimated as providing almost 10x as much light as background stars.

A Realistic Video of What You'd See Flying Through Deep Space I've read that the sky contains 12.7 million times more area than the Hubble Deep Field, and I've always been amazed at that. So using the metaphor that is commonly used, that's a lot of eight-foot soda straws. And I'm inclined to ask: Even if we do develop FTL like an Albicuierre drive or something like that, would intergalactic travel be feasible?

Phoenix Communication satellites in geosynchronous orbit (GEO), approximately 22,000 miles above the earth, provide vital communication capabilities to warfighters. Today, when a communication satellite fails, it usually means the expensive prospect of having to launch a brand new replacement communication satellite. Many of the satellites which are obsolete or have failed still have usable antennas, solar arrays and other components which are expected to last much longer than the life of the satellite, but currently there is no way to re-use them. The goal of the Phoenix program is to develop and demonstrate technologies to cooperatively harvest and re-use valuable components from retired, nonworking satellites in GEO and demonstrate the ability to create new space systems at greatly reduced cost.

NASA develops 3D printing factory in space News: NASA is developing an orbiting factory that will use 3D printing and robots to fabricate giant structures such as antennas and solar arrays of up to a kilometre in length, as part of its ongoing search for extra-terrestrial life. The US space agency this week announced it was awarding technology firm Tethers Unlimited Inc (TUI) a $500,000 contract to develop the facility. The NASA funding - a second-phase contract that follows an initial contract issued earlier this year - will allow TUI to continue work on its SpiderFab technology, which allows large-scale spacecraft components to be built in space, avoiding the expense of building the components on earth and transporting them into space using rockets. “On-orbit fabrication allows the material for these critical components to be launched in a very compact and durable form, such as spools of fiber or blocks of polymer, so they can fit into a smaller, less expensive launch vehicle.”
Space is a place for finished products. The satellites we send into orbit are checked, rechecked and then triple checked to make sure that nothing will fail. That finished product is then neatly folded, packed away atop a giant rocket, and blasted off into orbit. But one company in the US, recently awarded $500,000 (£320,000) by Nasa, wants to change this paradigm. Nasa-backed space spider concept to build giant satellites in orbit
