Aurora extravaganza in space

Colorful videos prove that the astronauts on the International Space Station had the best seats in the house during last month’s flare-up of auroral activity.

NASA’s Gateway to Astronaut Photography of Earth is offering a whole new batch of time-lapse videos from the Jan. 25-30 period, when an active region on the sun was blasting out a healthy dose of electrically charged particles and lighting up Earth’s upper atmosphere.


These latest videos are notable because they’re assembled from still pictures that were taken at a rate of one frame per second. As a result, the pace of the videos is a near match for the true speed of the space station as it makes its 90-minute orbit around our planet.

The video above documents a minute of flight heading east from the Pacific over the Canadian West Coast, heading toward southern Alberta near Calgary. I love watching the ripples and flashes of the green aurora over Canada — seasoned with a dash of red from the atomic oxygen that exists at higher altitudes. Why is there red as well as green in the aurora? We’ve addressed that question before, but this Aurora FAQ from the University of Alaska provides a quick explanation.

Here are a couple more videos, tracking the space station’s flight over the U.S. East Coast as well as central North America. But you don’t have to stop here. Visit NASA’s Gateway, which offers still photos from the space station in addition to the videos, and check out the YouTube channel for NASA Crew Earth Observations. My favorite places for space imagery also include the Fragile Oasis Facebook page, NASA astronaut Ron Garan’s Google+ page and Jason Major’s Lights in the Dark blog.

If auroras, atmospheric phenomena and solar activity are your thing, you can’t do much better than SpaceWeather.com, which is keeping track of lovely aurora pictures like this one from Chad Blakley at Abisko National Park in Sweden. Be sure to check out Blakley’s Lights Over Lapland website while you’re at it.

Photographer Chad Blakley captured this view of the northern lights over Sweden’s Abisko National Park on Feb. 6. “The lights started around 6:00 p.m. and continued into the very early hours of the morning,” Blakley told SpaceWeather.com. Check out Blakley’s gallery on SpaceWeather.com for still more stunning views.
