How to watch the ‘rainbow’ total lunar eclipse (foxweather.com)
The upcoming total lunar eclipse is sometimes known as a "blood moon eclipse" because of how Earth’s atmosphere reflects red light. Still, if you get the chance to watch the eclipse through a telescope, there are even more colors of the rainbow to see.
Ahead of the eclipse, astronomer Derek Demeter helped FOX Weather understand why it is called a "blood moon" and that it might be time to rebrand total lunar eclipses as "rainbow" moons.
Demeter is the director of Emil Buehler Planetarium at Seminole State College in Florida. The Emil Buehler planetarium is preparing to celebrate the eclipse by offering a public viewing with telescopes and a livestream with expert commentary.
The May 15-16 total lunar eclipse is often called a "blood moon" because Earth’s atmosphere reflects light creating a red glow on the moon.
On the East Coast, it starts on May 15 with a partial eclipse about two hours after sunset. When the moon rises for the West Coast, the eclipse will already be well underway.
The total eclipse begins at 11:29 p.m. EDT, 10:29 p.m. CDT and 8:29 p.m. PDT.
For those on eastern time, Demeter said the best part of the eclipse starts around 10 p.m. That’s when the darkest part of the shadow begins to create a noticeable change in the moon’s light.
Around 11:30 p.m. is when the main part of Earth’s shadow falls over the moon, known as totality.
"The moon is right in the middle of the Earth's shadow at that point, and then it will progress from there," Demeter said.
At 12:10 a.m. EDT (9:10 p.m. PDT), the deepest eclipse will be visible. The eclipse is over at 2:50 a.m. EDT and 11:50 a.m. PDT.
