A total lunar eclipse, promising a dramatic 'blood-red' moon, will soon grace the skies – the last such spectacle until late 2028.
The spectacle will be visible on Tuesday morning across North America, Central America, and the western part of South America. Australia and eastern Asia can catch the event on Tuesday night. Partial stages, appearing as small bites taken out of the moon, will be observable from Central Asia and much of South America, though Africa and Europe will unfortunately miss out.
Solar and lunar eclipses occur due to a precise alignment of the sun, moon, and Earth, with NASA reporting between four and seven annually. These phenomena often follow each other, and Tuesday's total lunar eclipse arrives just two weeks after a 'ring of fire' solar eclipse captivated people and penguins in Antarctica.
During a total lunar eclipse, the Earth is between the sun and full moon, casting a shadow that covers the moon. The so-called blood moon looks red because of stray bits of sunlight filtering through Earth's atmosphere.
The show unfolds over several hours, with totality lasting about an hour.
Compared to a solar eclipse, “the lunar eclipse is a little more of a relaxed pace,” said Catherine Miller at Middlebury College's Mittelman Observatory.
For those in the path, there's no need for any special equipment to observe — just a clear, cloudless view of the sky.
Use a forecasting app or any online celestial calendar to look up the exact timing for your area. Venture outside a few times to see Earth's shadow darken the moon, eventually revealing the reddish-orange orb.
“You don’t have to be out there the whole time to see the shadows moving,” said astronomer Bennett Maruca with the University of Delaware.
There's a partial lunar eclipse on the docket for August, visible across the Americas, Europe, Africa and west Asia.
