From the November 2008 special issue of National Geographic magazine.
There are few things in the world as fascinating and visually stunning as northern lights — or aurora borealis — and Tor Even Mathisen’s masterful time-lapse capture of recent lights from Tromsø, Norway really hits the spot:
It’s not at all surprising that the people of old thought these lights to be gods dancing in the sky.
No… you can thank our violent Sun and the Earth’s magnetic field for this dance.
The dish soap probably makes it a tad sour, but at least it’s visually satisfying.
Another great Symphony of Science video from John Boswell!
“A Wave of Reason” is the seventh installment in the Symphony of Science music video series. It is intended to promote scientific reasoning and skepticism in the face of growing amounts of pseudoscientific pursuits, such as Astrology and Homeopathy, and also to promote the scientific worldview as equally enlightening as religion. It features Carl Sagan, Bertrand Russell, Sam Harris, Michael Shermer, Lawrence Krauss, Carolyn Porco, Richard Dawkins, Richard Feynman, Phil Plait, and James Randi.
Take it in.
From NASA APOD:
There’s no place like home. Peering out of the windows of the International Space Station (ISS), astronaut Tracy Caldwell Dyson takes in the planet on which we were all born, and to which she would soon return. About 350 kilometers up, the ISS is high enough so that the Earth’s horizon appears clearly curved. Astronaut Dyson’s windows show some of Earth’s complex clouds, in white, and life giving atmosphere and oceans, in blue. The space station orbits the Earth about once every 90 minutes.
