Stunning Time Lapse of Lasers at Mauna Kea Observatories in Hawaii

Sean Goebel, a graduate student in astronomy at the University of Hawaii, has made this beautiful and fascinating time-lapse film of the observatories on Mauna Kea shooting laser beams into the night sky over the Big Island of Hawaii.

The lasers are part of the observatories’ adaptive optics systems, which compensate for distortions in light traveling through the Earth’s atmosphere. “Just as waves of heat coming off pavement blur out the detail of faraway objects,” explains Goebel on his Web site, “winds in the atmosphere blur out fine detail in the stars/galaxies/whatever is being observed. This is the reason that stars twinkle. The laser is used to track this atmospheric turbulence, and one of the mirrors in the telescope bends hundreds of times per second in order to cancel out the blurring.”

This is Geography

Screen Shot 2013-05-26 at 9.08.07 AMAs geographers, teachers, and general education enthusiasts we are asking for your help in a national campaign to raise the profile of Geography in Canada. This is Geography is a joint project of CG Education and the Canadian Association of Geographers (CAG) aimed and increasing Canadians’ perception of geography as a subject area and integral aspect of our daily lives.

The program consists of two main strands: Google Plus Hangouts and a photographic collection.

We are asking all Canadians to upload photos that answer the phrase “This is Geography” on the website and on Twitter and Instagram using the hash tag #thisisgeography. We want you to also include a brief description of why your photo shows geography. We know that there are endless possibilities of photos that you can upload so get creative! We’ve started the collection but need your help!

Over the next few months we have planned to host our first few Google+ Hangouts. Each hangout will focus on one aspect of geography and have four expert panelists speaking about the issue at hand. The first hangout is scheduled for May 15th at 4:00 p.m. ET and will take a look at some cool “Geo Jobs.” Once completed the hangouts will be uploaded to Canadian Geographic’s YouTube channel, so even if you can’t watch at 4:00, check it out afterwards.

Together we can let Canadians know just how inclusive of a subject area Geography is so get out there and start spreading the word!

National Geographic Compass: The Oceans Edition

Featured Resource: The Ocean Edition
From Ocean Currents to Sustainable Seafood

From 2009 to 2012, National Geographic Education Programs was honored to receive two grants from Oracle totaling two million dollars. These funds were used to address issues in ocean science and geography, including the impact of human activities on the ocean and ocean conservation.

With the help of Oracle, we were able to create more than 500 unique educational assets to help bring ocean education into the classroom.

This month, we’re highlighting some of our favorites for you!

The Activity Books were assembled by the team responsible for – the official Government of Canada website for Science and Technology information and resources.

Activities and ideas – as well as all sorts of other educational resources – available for primary, middle and secondary levels.

Climb Three of the World’s Highest Peaks on Google Street View

What’s surprising about Everest Base Camp is the color. It’s a flinty, gray place littered with shards of Himalayan sandstone and shale. Here and there appears a vivid green pool of alpine water. And then there’s the red, blue and green prayer flags hung by Himalayans to blow blessings in the wind.

Google Street View’s latest project, the World’s Highest Peaks, takes us to Everest and two other mountains included in the Seven Summits—the highest mountains on each of the seven continents.
