The Green Comet is making its closest pass to Earth Wednesday night and the skies are looking clear enough for Adler Planetarium to host a virtual viewing party.

Enjoy a cosmic Christmas, with all five naked-eye planets visible in the sky. The moon, Mercury and Venus will form a sparkling triangle on Christmas Eve.

Sky watchers will have their eyes peeled Wednesday night for a rare-ish celestial event: an “eclipse” of Mars.

Election Day 2022 will kick off with a pre-dawn total lunar eclipse. There won't be another like it until March 2025.

Jupiter is making its closest approach to Earth since 1963 on Monday night, and the views should be especially spectacular.

While this year's that display might be a little harder to see than in past years, Chicago Astronomer Joe Guzman says it’s still worth getting out there and looking up.

The five planets that are visible to the naked eye are now lining up in a particularly unique formation in the early morning hours, all of them appearing in the same part of the sky. Want to catch the show? We’ve got tips.

After a string of clear, sunny days, rain and clouds are expected to move in for the weekend. Depending on the extent of the cloud cover, the eclipse could still deliver an “ooh-aah” moment, or it could be a womp-womp for Chicago.

“All you need are your eyes, a comfortable chair and a blanket to enjoy,” Chicago astronomer Joe Guzman said. “Those who have telescopes set them up and share this experience with your family as we observe one celestial object get in the way of another!” (WTTW News)

A celestial show is coming to Chicago next weekend - on the evening of Sunday, May 15, a lunar eclipse will grace the night skies. Chicago astronomer Joe Guzman says it's a great reason to spend an evening moongazing.

The Sun put on a spectacular show Wednesday, emitting a “significant solar flare,” according to NASA. Now scientists are bracing to see what the resulting space weather will have in store for Earth.

Equinoxes are always extra special in Chicago, thanks to the city’s grid. The sun rises due east and sets due west on the equinox, creating a phenomenon known as “Chicagohenge“ (in reference to Stonehenge), when the sun is strikingly framed by the city’s skyscrapers. The official start of astronomical spring takes place Sunday at 10:33 a.m.

Comet Leonard, discovered in January of this year by astronomer Greg Leonard, is racing toward the sun and will make its closest pass of Earth in the coming days. The Adler Planetarium is hosting a viewing session Tuesday morning.

For once, the weather cooperated in Chicago. Astronomers at the Adler Planetarium proclaimed: “What a stellar view!”
