Editor’s Note (2/5/24): On April 8, 2024, a total solar eclipse will be visible from parts of the U.S., Mexico and Canada. This will be the last opportunity to see the phenomenon in the contiguous U.S. and Canada until 2044.

Excitement about the August 21, 2017, eclipse is as hot as a star, but solar eclipses happen at least twice a year, when the orbits of the moon and Earth align with the sun. What is unusual this time is that the moon will totally block the sun, instead of doing so partially, and that the strip of darkness cast on Earth will fall on millions of people rather than plankton out at sea or polar bears or penguins at the poles. Forty-six solar eclipses of various types will occur over the next 30 years. Grab a friend and go.

Eclipses to the Year 3000

Creatures on Earth will witness 2,354 solar eclipses between 2017 and 3000. They will occur at regular intervals of slightly less than six months, which means that each year, eclipse season shifts on the calendar. Eclipses also occur in cycles; each successive eclipse in a cycle casts a similar shadow band on Earth. During a total eclipse, complete darkness at any given spot lasts less than seven minutes, so if you want to see one, plan ahead.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
