Footage Note: The slower video represents a closer resemblance to the true speed of the International Space Station; this footage was shot at one frame per second. Clips are all marked with an *.

There are more International Space Station videos in the archives, including a tour of ISS and what is perhaps our favorite time-lapse view: Further Up Yonder: A Message From ISS To All Humankind

Thanks, @MarbleSpark.

From PBS’ Digital Studios, It’s Okay to Be Smart’s The Auroras, Earth’s Art Show! Learn More about the invisible forcefield — a magnetic field — that protects all life on Earth from space radiation, primarily Sun’s solar winds that bombard our atmosphere constantly. 

jtotheizzoe:

All that science has a beautiful side effect: It makes the auroras! The Northern and Southern lights are the result of the solar wind and its dance with Earth’s magnetic field and polar atmosphere. It’s like our own cosmic light show!

Watch more about space weather and magnetic fields, plus dont’ miss this fabulous-looking vid about how the aurora borealis is created in our archives.

When you drill 364 meters (1194 feet) down into Antarctic ice, taking out a cylindrical section called an ice core, you can find out about the Earth’s temperature and carbon dioxide levels from over 20,000 years ago. Information is held within the oxygen atoms in the ice and the air bubbles that formed within it.

Measuring ice cores is an effective form of time travel for scientists like the British Antarctic Survey team, who are studying how the Earth’s climate is changing. And Antarctica is full of untapped information:

Antarctica is thought to have been covered by ice for over 30 million years. So far, scientists have drilled ice cores stretching back 800,000 years, and they are now working to extend their records back to 1.4 million years ago.

In this video, Ice Core Scientist Nerilie Abram explains the process. You can also read more about the team’s work here.
