A total lunar eclipse is set to take place Thursday night into early Friday morning, causing the moon to turn a deep red color and making for some spectacular views.
Here’s everything to know about the eclipse and where to see the “blood moon” in Chicago.
What happens during a lunar eclipse?
A lunar eclipse occurs when the moon, Earth, and sun align, causing the moon to fall behind the shadow of the Earth, according to NASA.
A total lunar eclipse occurs when the moon settles within the darkest portion of the Earth’s shadow, known as the “umbra.” Total lunar eclipses cause the moon to appear deep red in hue, hence the term “blood moon.”
What causes the “blood moon” phenomenon?
The “blood moon” occurs due to the same element that makes the sky appear blue and sunsets appear red, according to NASA. Sunlight contains a whole rainbow of colors which appear differently depending on how they pass through earth’s atmosphere.
During a lunar eclipse, the Earth blocks the majority of visible sunlight. The remaining light filters through the Earth’s atmosphere before reaching the surface of the moon, giving it a hazy red color similar to what one would observe during a sunset.
How to observe the eclipse?
You don’t need any special equipment to observe the total lunar eclipse! A pair of binoculars or a telescope can enhance the viewing experience, but all you really need is your eyes to take in the phenomenon.
The eclipse will begin around 11 p.m. Thursday night in Chicago, before reaching totality around 1:30 a.m. Friday, according to NASA.
The best spots for stargazing in Chicago are areas with minimal light pollution and unobstructed views of the night sky—ideally, away from buildings, trees, or other structures blocking the horizon.
For the best view of this week’s blood moon in Chicago, we recommend heading to the lakefront, particularly near the Adler Planetarium. This area offers reduced light pollution and sweeping views of the sky over Lake Michigan.
