After a year of delays, the Array of Things urban data sensor project is back on track and prepping to collect all sorts of information on Chicago's streets by early next year. Joining us to discuss the initiative are the project’s lead scientist Charlie Catlett and author Lori Andrews.

Conservationist George Archibald has spent his life working to bring cranes back from the brink of extinction. He joins “Chicago Tonight” to talk about his groundbreaking work which has been recognized around the world.

Did you take pictures of Sunday's harvest supermoon eclipse? We'd like to see them. Use the form below to share your photos with us and we'll use them in an online gallery.

Last week NASA said it would be making a major announcement today about a discovery on Mars. While some space fans might have been hoping it was about finding life, the announcement was about something almost as significant. Adler Planetarium astronomer Lucianne Walkowicz joins us to discuss the latest on the Red Planet.

Weather permitting, the Chicago area will be treated to prime time, front-row seats for a rare astronomical phenomenon Sunday evening when a total lunar eclipse of a simultaneous harvest moon, supermoon and blood moon rises above the horizon.

Archival photos from the Field Museum depict researchers and the taxidermy they worked on – and loved posing with.

A group of local science researchers want your help on a truly wild project. Learn about Chicago Wildlife Watch, and how you can help them better understand the urban ecosystem of Chicago.

Emily Graslie may just have the coolest job in the world. She's the Chief Curiosity Correspondent for the Field Museum and the driving force behind the popular YouTube channel The Brain Scoop. Graslie joins Chicago Tonight to discuss her work popularizing science.

We conduct a postmortem on Spike, the smelly corpse flower that failed to bloom at the Chicago Botanic Garden. What happened? Paris Schutz has the story.

As the Metropolitan Water Reclamation District cuts the ribbon on it's new sewage reservoir, we revisit Jay Shefsky's visit in May to the bottom of the Thornton Quarry.

Patents recently issued to Northbrook-based insurance giant Allstate could allow the company to monitor your car for sources of distraction, collect health data on drivers, and even monitor what's going on around your vehicle. The company says any new technology will improve driver safety, but some are worried it could violate the privacy of drivers, passengers and passers-by. 

After much anticipation, the Chicago Botanic Garden on Saturday night announced that Spike is not expected to bloom. 

The Chicago Botanic Garden is on death watch. Officials there say the famed titan arum plant, more popularly known as the "corpse flower," could bloom in a matter of hours and emit its notorious foul odor. Chicago Tonight was on the scene on Wednesday. Also, watch a livestream of the famous plant called Spike.

This month in Nature, an international team of researchers released some of their key findings after a first-of-its-kind study of the genome of the California two-spot octopus. The team found a massive and unusually arranged genome, with many genes unique to the octopus that could provide clues to the unusual animals. One of the researchers, University of Chicago neurobiologist Cliff Ragsdale, joins Chicago Tonight to discuss the ongoing project.

The Chicago Botanic Garden is getting ready for the big stink. His name is Spike, and the nearly 70-inch tall titan arum has been in the spotlight for weeks. Learn more about the rare plant and watch a livestream from the CBG.

Recent reports in science journals point to a mass extinction currently underway. Field Museum senior conservation ecologist Doug Stotz joins us to discuss the phenomenon and his work in South America with the museum's Science Action Center. He'll also share specimens of extinct birds from the Field collection, including the passenger pigeon and the Carolina parakeet.
