It’s a ravioli! It’s a UFO! It’s a moon

NASA on Thursday released pictures of Pan, one of Saturn's many moons, and its distinctive shape is drawing comparisons to flying saucers and stuffed pasta. The images of the moon come courtesy of NASA's Cassini spacecraft, and reveal the UFO-like form of the tiny satellite, which has an average radius of just 8.8 miles.

NASA: Space Alters Your DNA In Bizarre Ways

Does going into space fundamentally change our biology? It's not a casual question. Human beings evolved to live in a very specific ecological niche, and no matter how tough DNA is , nature never planned for us to sit on a pile of explosives and fling ourselves into an airless void full of rocks and ionizing radiation.

NASA images show Saturn’s bizarre ‘wavemaker’ moon Daphnis

A stunning new image from NASA's Cassini spacecraft shows the closest view yet of Saturn's 'wavemaker' mini-moon Daphnis as it creates ripples along inside one of the planet's rings. The 5-mile-wide moon orbits within a 26 mile wide gap known as the Keeler Gap, and its gravity causes the edges to 'wave' in both the horizontal and vertical directions.

NASA’S Mars rover Curiosity discovered this odd rock in the Red Planet’s Gale Crater six days ago.

There's no end to the earthly items that Red Planet UFO enthusiasts have "discovered" on Mars - a snake , a coffin , traffic light , cat , lizard , even a sasquatch , just to name a few. But, as Live Science reports, one rock that has piqued scientists' interest is a unusual dark-gray object that seems out of place with the rest of the reddish rock and dirt spread across the Martian landscape.

Weird clouds linger on Saturn’s moon Titan

The upper image shows relatively cloud-free skies, while the lower one captures widespread cloud cover. NASA's Cassini spacecraft flew over Titan on June 7 and July 25 and captured strikingly different photos of the moon's high northern latitude using the probe's Imaging Science Subsystem and Visual and Infrared Mapping Spectrometer .
