The trifecta includes a total solar eclipse for part of the world, a massive meteor shower and a special gathering of planets in the morning sky.
Liberty Science Center's planetarium director Mike Shanahan is breaking down what is going on up in the sky and where to look.
The solar eclipse took place Wednesday afternoon as the moon passed between Earth and the sun, blocking the sun. A partial solar eclipse (9%) occured over the New York City area.
Millions of people crowded cloudless cities and towns in Spain on Wednesday in search of the best views of the total solar eclipse. It was the country's first total solar eclipse in more than a century.
Across a wide band of northern and central Spain, millions of people expected to have some of mainland Europe's best views of the eclipse.
Totality - when the moon completely covers the sun's light - was expected to last less than 2 1/2 minutes, reaching its maximum duration off Iceland's west coast.
Many people will remember the big solar eclipse in 2024, but the difference between a partial and total solar eclipse is the difference between night and day.
During a total eclipse, the moon entirely blocks the blazing disk of the sun, causing the land to grow dark.
"It's the most beautiful astronomy experience I guarantee you'll ever have in your life," Shanahan said.
The partial eclipse peaked at 1:54 p.m. in the Tri-State, but few may have noticed.
"One-tenth of the sun will be blocked by the moon, so a shallow one, still one worth looking at as long as you have a safe way of viewing it," Shanahan said before the event.
And during the Perseid meteor shower, Earth will pass through debris left behind by a massive comet, creating streaks of light.
Shanahan said the Perseid is the most consistently reliable meteor shower of the year. It peaks in the predawn hours of Aug. 13.
"The moon is a greatest foe of good viewing, so having a new moon is great because you can't see a new moon; it's better to be away from the city, get to a dark location," Shanahan said. "Also, it's better from midnight to dawn because then you're facing in towards the comet cloud."
And the planetary gathering means the planets will appear in the same general area of the sky at the same time.
If you're willing to get up before the sun, you have the opportunity to see a parade of six planets across the predawn sky.
According to The Planetary Society, if the weather is good and the sky dark enough (sorry, city dwellers), you should be able to see "bright Mercury, very bright Jupiter, reddish Mars, and yellowish Saturn" without any assistance.
