Ganymede Underground Ocean

NASA researchers discovered that the Jupiter-orbiting moon Ganymede - the largest moon in our solar system - has an ocean beneath its icy surface, raising the prospects for life. It's 60 miles (100 km) thick, which is 10 times deeper than Earth's oceans. All this water is buried under a 95-mile (150-km) crust of mostly ice.

Aerogel World's Lightest Solid

Aerogel is basically a synthetic porous ultralight material made from a gel, in which the liquid component has been replaced with a gas. Despite its name, aerogels are solid, rigid, and dry materials that do not resemble a gel in their physical properties. The material is 98.2% air, thanks to the lack of solid material, allowing it to be almost weightless. Continue reading for a video demonstrating what it sounds like when dropped.

Blue Sunset Mars

Most sunsets are boring, this one on Mars is not, or at least until humans start living on the Red Planet, and only then would it become a common sight. According to NASA, "The sun descends to the Martian horizon and sets in this 30-second movie simulation using images from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity." Let's just hope they release a sunrise video next. Continue reading for the clip.

NASA Titan Submarine

What would a submarine to explore the liquid methane seas of Saturn's Moon Titan look like? NASA has unveiled an innovative 2200-pound submarine design that would explore both the shoreline and the depths of this strange world that has methane rain, rivers and seas. It would be powered by a 1 kW radiothermal Stirling generator, which would not only provide power to propel the craft, but also keep the electronics from freezing.

Neil Armstrong Camera

Neil Armstrong, he first man to walk on the moon, kept a bag of Apollo 11 mementos stashed away in his Ohio house for more than 40 years between the mission and his death. Inside the bag, there was a 16mm movie camera and 10mm lens that first shot Apollo 11's descent to the moon's surface through a window on the lunar module. Other items included tools, helmet straps and cables taken aboard the Lunar Module Eagle for the landing. These were all supposed to have remained on the lunar surface to keep the weight down. Continue reading for the full 3-hour Apollo 11 NASA footage.

Tilt-Shift Galaxy

When you see the images, paintings might come to mind, but they're actually tilt-shifted (selective focus to simulate miniature scenes) photos of real galaxies in space, created by Italian artist St. Tesla. Tesla says: "Macrocosm and microcosm is an ancient Greek Neo-Platonic schema of seeing the same patterns reproduced in all levels of the cosmos, from the largest scale (macrocosm or universe-level) all the way down to the smallest scale (microcosm or sub-sub-atomic or even metaphysical-level). In the system the midpoint is Man, who summarizes thecosmos. I was doing some researches and I found experiment with miniatures of space with tilt shift so I decided to try my own. The result has been nebulae, galaxies and supernovae transformed into microorganism." Click here to view the first image in this week's funny demotivational poster gallery.

View From Other Side

NASA has just released a video titled "A View From the Other Side", showing the moon's far side as it passes through its phases and libration. The views were created with imaging data from the Lunar Reconnaissance Orbiter, and complements NASA's annual Moon Phase and Libration visualization that shows the Moon as seen from Earth after theyreceived a number of comments requesting a view from the dark side.

NASA ISS UFO

NASA has been known to cut off its live feed from the International Space Station whenever an unidentified flying object appears. There were two separate occasions this month where UFO hunters claim to have spotted mysterious objects floating on screen before going the camera goes offline. Toby Lundh recently spotted the one you see above right outside the space station, moments before the stream was disconnected. Continue reading for two videos and more information.

Ever wonder where some of the astronauts aboard the ISS browse the internet? It just might be inside the Cupola module, which as special windows that provide a panoramic view of Earth, allowing them to take images using 8 cameras. Cupola also houses one of the space station's two robotic work stations used by astronauts to manipulate the large robotic arm seen through the right window. Click here to view the first image in today's viral picture gallery. Continue reading to watch the top five viral videos of the day.

Largest Hubble Image

What you're looking at above is the sharpest and largest Hubble image ever taken. It stretches 48,000 light-years across the Andromeda Galaxy's disk, and shows more than 100 million stars. This galaxy may be located 2.5 million light-years from Earth, but since Andromeda fills up so much of Hubble's field of view, it was able to capture incredible detail in its survey of the galaxy. "Hubble traces densely packed stars extending from the innermost hub of the galaxy. Moving out from this central galactic bulge, the panorama sweeps from the galaxy's central bulge across lanes of stars and dust to the sparser outer disk," said a Hubble representative.
