On Sunday night you’ll be able to get a glimpse of a blood-red moon on during the lunar eclipse.

“The lunar eclipse happens when we have three things lining up in succession; we have the sun, we have the moon, and we have the earth, but the earth is in the middle,” said Tim Yaworksi, a member of the Saskatoon centre of the Royal Astronomical Society of Canada.

“The earth is cutting the light from reflecting off the moon. So whats going to be happening is as it goes into that shadow, what were going to start to see are chunks of the moon being eaten away.”

Yaworski says the phenomenon will be visible at moonrise, but after 10 p.m. is when things will get interesting.

“The moon itself, as it goes into that shadow, is going to turn a blood red colour, sort of a rusty, rusty red colour as its fully engulfed in the earth shadow,” he said.

“Whatever light is sort of wrapping around the earths atmosphere, basically stray light thats shining onto the moon. Now the reason it’s blood red is, the earth’s atmosphere basically acts like a big prism, and all its letting through essentially is blue-spectrum lighting, which through the miracle of physics, looks red when it hits the moon.”

Yaworski says a lunar eclipse isn’t a rare occurrence.

“This year in Saskatchewan were going to have two full total lunar eclipses, you’ll be able to see one later in the fall, in November and this one here, so if you miss it youll have another chance,” he said.

No special equipment will be needed to view the lunar eclipse, and unlike a solar eclipse, you’ll be able to look directly at it.

“You dont need any eye protection, youre not going to go blind, and if you miss the first 15 minutes of it, theres more coming,” said Yaworski.

“The other nice thing about a lunar eclipse is you dont necessarily have to be in a dark sky area. Its not like most things with astronomy where you want to be out away from the city where you do not worry about light pollution.”
