Bear McCreary composed the music for Battlestar Galactica. Enough said.
Alex Rivest has a PhD in Neuroscience from MIT. Oh, and he’s competiting to be a NASA astronaunt. Oh, and one more thing, he’s put together this beautifully artistic time lapse of earth as seen from the International Space Station. You see tons of aurora, the flickering of lightning from storms on the earth and the bright lights of the world’s largest cities. He also has a blog post that answers a lot of questions you may have after watching the video. You can find it here. Enjoy!
Titan, one of Saturn’s most interesting moons, has yet another mystery: a giant vortex on it’s south pole. Cassini spotted the vortex on June 27th, 2012. There are similar phenomena that occur on Earth that are associated with the changing of the seasons, but this vortex is especially interesting because it extends very high into the atmosphere.
the structure inside the vortex is reminiscent of the open cellular convection that is often seen over Earth’s oceans,” said Tony Del Genio, a Cassini team member at NASA’s Goddard Institute for Space Studies, N.Y. “But unlike on Earth, where such layers are just above the surface, this one is at very high altitude, maybe a response of Titan’s stratosphere to seasonal cooling as southern winter approaches. But so soon in the game, we’re not sure.”
I love the pictures from the NASA Cassini mission. This one is especially interesting because it displays the gravitational effects that Saturn’s moons have on its rings. You can see that it almost has a ripple effect as if it were flowing through a liquid.
Saturn’s moons Daphnis and Pan demonstrate their effects on the planet’s rings in this view from the Cassini spacecraft.
