One Great View of Earth for the Summer Solstice

A new satellite image beautifully highlights the Earth forming a perfect crescent as the midnight sun beams down on the far northern reaches of the globe

Join Our Community of Science Lovers!

Planning to host a party for the summer solstice tomorrow? Here’s a view that will help build some excitement, courtesy of a satellite positioned about 36,000 miles from the Earth’s surface.

Brian McNoldy, a tropical storm researcher at the University of Miami, grabbed an image of the Earth as GOES-West, a satellite operated by the National Oceanic and Atmospheric Administration, that shows the Earth at local midnight last night. It beautifully highlights the earth forming a perfect crescent as the midnight sun beams down on the far northern reaches of the globe.

While the solstice is officially at 6:51 a.m. Eastern on Saturday, McNoldy explained in an email that the image captured is a pretty close representation of what it will look like from the same vantage point. In other words, this is a solstice drill that’s as close to the real thing as possible.

McNoldy also shared another bit of trivia: you won’t see a similar view from the opposite side of the planet. GOES-West, which in satellite parlance sits in a geostationary orbit above the 135°W meridian, snaps a full Earth picture at local midnight everyday. However, GOES-East, its aptly-named partner on the other side of the planet, operates on a slightly different schedule and the closest you’ll get to this view is a photo taken at 12:45 a.m. local time. That view, while still pretty spectacular, would show a warped crescent as opposed the perfection of GOES-West's view.

Feel free to add that to your trivia game at your solstice party.

The solstice is commonly referred to as the longest day of the year, a statement that leaves most folks in the Southern Hemisphere shaking their heads. A more accurate description of the solstice is that due to the position of the Earth’s orbit around the sun, the North Pole will be angled as close to the sun as possible this year. That makes it seem like the longest day of the year in the northern hemisphere but the shortest in the southern hemisphere. After Saturday, the two hemispheres’ luck will start to reverse which each day getting shorter in the northern half of the globe and longer in the southern half.

You can put that in your trivia game, too. And in the vein of previous Friday diversions, here’s a tune (or two) to accompany your solstice thoughts.

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,
