When the moon passes through the Earth's shadow, it causes the moon to look very unusual for a short period of time. This event is called a lunar eclipse, and it occurs roughly twice a year. There's one viewable to folks outside of North America on June 15, so sit back and learn more about how lunar eclipses work in this video! 

This video is also available in stereoscopic 3D, viewable by many kinds of 3D devices, including common red/blue paper glasses that you might have lying around! To view this video in 3D, click here: http://youtu.be/F5JRVOw6mes

This animation show how the tidal forces push and pull the Earth's oceans.

The Hopewell Rocks Tidal Exploration Site is a fantastic place to experience the Bay of Fundy's world famous tides. To help our guests understand a full tide cycle, we set up a camera and took 1 photograph per minute from before sunrise until after sunset.  The resulting 926 photos were then each used as a frame of video to create this glimpse of the world's largest tides. To fully appreciate this natural wonder, come spend a day with us on the ocean floor.

Why Does Venus Spin Backwards?

The full moon might seem bigger on the horizon than when it's higher up, but when does it actually take up more space in the sky?

The Weird Optical Illusion that Changes the Moon's Size

The total solar eclipse from Madras, Oregon on August 21, 2017. As the moon passed in front of the sun turning day to night and revealing the sun's corona, apparently all I could think to say was 'Oh my goodness!'

Special thanks to Patreon Supporters:

Everyone says not to photograph your first solar eclipse and I think they might be right. I was focused on getting the exposure right for Bailey's beads and the diamond ring, plus making sure to get the corona and solar flares. This was a bit stressful but I'm delighted with the results.

This video originally included more info but since I'm uploading from Madras where the internet is sluggish, I cut out three minutes so the upload would happen before I had to leave for my flight.

Special thanks also to Dr. Teagan Wall for sharing this experience with me and Raquel Nuno for inspiring me to come to Oregon.
