Limited Edition: Total Solar Eclipses

You’ve probably heard a lot about the upcoming solar eclipse on August 21, 2017. You may have also heard that solar eclipses are a rare phenomenon. Total solar eclipses (when the Moon completely covers the Sun) occur approximately once every year and a half—that works out to two to three eclipses of all kinds each year and only two total solar eclipses every three years. This might not sound so rare to you, but the shadow the Moon casts on the Earth is, at most, 274 kilometers (170 miles) across. That shadow covers roughly 37,015 square kilometers (23,000 square miles) at any one time: only 0.01% of the total surface area of Earth! At most, a total eclipse can last about 7 minutes in one place, so the chances of a total solar eclipse coming to you during your lifetime are pretty low. For instance, the last total solar eclipse that passed through Washington, D.C. was in 1478, and the next one is not coming until 2444!

Beyond Totality: Appreciating the Partial Eclipse

Here we are, less than one week until a total solar eclipse crosses the United States. For the past three years, my excitement has been building, and all of my eclipse-chaser friends have been saying, “You HAVE to go see totality!” The path of totality (the narrow region where the Sun will appear totally blocked) is relatively convenient for North Americans, but many people won’t be able to travel and witness the total phase of the eclipse.

Road Trip to Totality

On Monday, August 21, a total solar eclipse is sweeping the nation. All of North America will be able to see at least a partial eclipse, but 14 states across the U.S. will have the unique opportunity to see a total solar eclipse, called the path of totality. There are approximately 12.5 million people living in the path of totality—an occurrence that happens only once where you live every 375 years! On the day of the eclipse, STEM in 30, a TV show we produce at the National Air and Space Museum for middle school students, will be broadcasting live from the path of totality in Liberty, Missouri, starting at 1:30 pm EST.

Right now is an exciting time to be volunteering here thanks to the total solar eclipse that will happen this summer. As an astronomy enthusiast and an eclipse chaser, I have some great advice to share on how best to view the 2017 eclipse.

The United States will play host to an extraordinary phenomenon known as a total solar eclipse on August 21, 2017. A solar eclipse occurs when the Moon passes between the Sun and the Earth.  Eclipses have occurred throughout history, and some have fascinating stories associated with them. Take the following two tales for example.
