Comet Tsuchinshan–ATLAS is one of the brightest in years. We've got tips on how to view this visitor from the outer solar system, even in Chicago.
The Great American Eclipse is almost here. Here’s how to make the most of the experience in Illinois and the Chicago area.
Sky watchers will have their eyes peeled Wednesday night for a rare-ish celestial event: an “eclipse” of Mars.
If the skies are clear, Chicagoans will have an excellent chance of seeing the eclipse Friday morning, with the best hours for viewing the event being approximately 1:30-4:30 a.m.
Jupiter is preparing to pass Saturn, an event known as a great conjunction. On Dec. 21, the two planets will come closer to each other than they’ve been in nearly 400 years — and it will be visible to the naked eye. 
For the first time in a decade, five planets will be visible at the same time in the pre-dawn sky – and you won't need a telescope to see them.
