The billowing radiance of the northern and southern lights is among the most beautiful sights known to humanity – and that's when seen from the ground. Imagine watching the lights from low-Earth orbit. Through the International Space Station's windows, 200 miles above Earth's surface, the auroras borealis and australis dance across continents. They're a regular treat for ISS astronauts who circuit the planet every few hours, passing frequently over Earth's polar regions, where the auroras are strongest.
Sandrine Ceurstemont, editor, New Scientist TV Auroras aren't the only light show shining above the Earth. The atmosphere itself can also produce light, creating rings of colour that glow in the dark. Now neuroscientist and moviemaker Alex Rivest has produced a new video that illustrates the phenomenon, called airglow . Atoms and molecules, excited by ultraviolet radiation from the sun, emit light when they return to their ground state or when they combine due to chemical reactions to create new molecules. During the day, scattered light from the sun masks this activity, so it only becomes visible after dark.
“This visualization shows ocean surface currents around the world during the period from June 2005 through December 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience… read more on nasa.gov ” Know what’s a bummer? Military spending is on the rise while NASA funding has been on a steady decline since 1992 . A big thanks is due to Erica for sending this in to remind us that they’re still doing great things and our boy Neil for some much needed perspective .
It's ironic to start a video saying that I shouldn't be pessimistic about the prospect of nuclear war and then following it with footage of Ronald Reagan. It's bizarre to try to inspire me with quotes from notable scientists and then showing me a quote from a man who continually cut funding from education. It's ridiculous to show me a bunch of hype about individuals pushing humanity forward and then touting the accomplishments of corporations. Why is Reagan in this video? Maybe I'm supposed to think the corporate profits made by Honda, Amazon, and Google will "trickle down" to me and improve my quality of life. Or maybe I don't want to remember an era of crushing poverty, cutbacks in schools, "ketchup as a vegetable," continual war, and the recurring fear of global thermonuclear obliteration.
A new video from NASA’s Solar Dynamics Observatory shows huge blasts of plasma, called solar prominences , curling around the sun’s tumultuous magnetic field. The remarkable activity was captured Nov. 14 to 15 using a wavelength of extreme ultraviolet light. For legal reasons it should be noted that only NASA is allowed to look directly at the sun
While you’re curled up comfy in your bed each night, the crew of the International Space Station is getting unrivaled views of our planet.

If you were an astronaut, this could be the view each day from your office window.
Scientists have generated the largest and most realistic simulations of the evolving universe to date with the aid of NASA's powerful supercomputer, dubbed Pleiades.
Astronaut Video Shows Spectacular Auroras From Space | International Space Station | Northern Lights, Southern Lights & AurorasStunning NASA videos are giving an astronaut's-eye view of spectacular aurora displays in the Southern Hemisphere.
Video Show: A Blueprint of the Universe | Big Bang, Universe Creation & Evolution | History & Future of the CosmosThe universe is a big place, near-infintely big, but there's a structure to our cosmos that astronomers are hard at work unraveling. Take a tour of some of the out-of-this-world structures that make our universe tick in this video show, "A Blueprint for the Universe," the first stop in SPACE.com's eight-weekday series to look at our universe's mysteries entitiled: The History & Future of the Cosmos .
The spectacular pink and red core of a lively nebula takes center stage in a new photo that exposes the stellar nursery's eye-catching clouds of gas, dust and newborn stars. The European Southern Observatory's Very Large Telescope (VLT), at the Paranal Observatory in Chile, captured the new image of the Omega Nebula.
