Blood Moon Rising: Chicago star gazers in for treat if weather holds out
Star gazers are hoping to catch a glimpse of a “Blood Moon, if the weather cooperates early Tuesday morning.
Dr. Mark SubbaRao took WGN inside Adler Planetarium’s Space Visualization Lab to explain the total lunar eclipse, which happens when the Earth, moon, and sun are lined up and Earth casts a shadow on the moon.
The eclipse starts at 1 a.m. CT Tuesday, with the blood moon appearing between 2 and 3:30 a.m.
“Because the Earth has an atmosphere, it doesn’t completely block the light on the moon. Some of the red light actually bends through the Earth’s atmosphere and lights up the moon during a total eclipse, and that’s the rusty red, blood moon,” said SubbaRao.
The last Blood Moon was in 2011. But because of the complicated combination of orbits, SubbaRao says we will be treated to four total lunar eclipses in a row, with the next one only 6 months away.
