Surfing Titan's waves in a nuclear-powered boat

Surfing Titan's waves in a nuclear-powered boat
Planning a trip to Titan, one of Saturn's moons? Well, you're going to want to go prepared. Why not bring along a nuclear-powered boat for sailing the seas of ethane, methane and propane?

That's what NASA-funded geologist Ellen Stofan suggests with her design, seen above. The Titan Mare Explorer (or TiME for short) uses nuclear power rather than solar power because the methane raine in Titan's atmosphere cuts down the suns rays considerably (as does the distance from the sun). It'll be powered by a new kind of nuclear power cell known as the Advanced Stirling Radioisotope Generator (ASRG). Cool! Be sure to send a postcard when you get there and let us know how the weather is.

New Gigantic, Glowing Saturn Ring Discovered [Astronomy]


See that tiny dot in the middle of that ring? That's Saturn. And the newly-discovered glowing ring is 13.4 million miles in diameter. The proverbial 800-pound gorilla has been discovered by the Spitzer Space Telescope, leaving every single astronomer speechless.
The ring hasn't been discovered till now for because it's so diffuse that it reflects very little sunlight. That makes it undetectable by optical telescopes. The particles in it, however, glow with heat radiation, which was captured by the Spitzer's infrared instruments.
This image is an artist representation of what Spitzer's discovered, showing us, once again, that we are still bloody clueless when it comes to almost everything around us. I can't wait to see the actual image.
