It may not seem like it lately, but the sun does indeed still exist. And NASA is sending a spacecraft to our friendly neighborhood star to get some answers.

A moonstruck nation celebrated the 50th anniversary of Apollo 11’s “giant leap” by Neil Armstrong and Buzz Aldrin at parties, races, ball games and concerts Saturday, toasting with Tang and gobbling MoonPies.

Fifty years after Neil Armstrong and Buzz Aldrin walked on the moon, some people insist it never happened and was all a big hoax by the U.S. government. Here’s a look at some of the most common claims and how they're explained away.

In research released on Friday, Nobel winning astronomer Adam Riess calculates the cosmos is between 12.5 and 13.0 billion years old - about 1 billion years younger than previous estimates.

A groundbreaking study concludes that human health can be “mostly sustained” for a year in space, a key finding that figures to help NASA with its mission of sending humans to Mars within two decades.

An ongoing NASA study aided by Northwestern researchers sent mice into orbit with the goal of learning more about the physiological effects of living in space. 

Ultima Thule, the relatively tiny object in the outer solar system, is now the farthest cosmic body to be reached by humans. We hear from the lead scientist behind the farthest flyby ever.

Retired University of Chicago astrophysicist Eugene Parker speaks with Chicago Tonight on Tuesday, July 31, 2018.

Next week, the retired University of Chicago astrophysicist, 91, will watch as a probe named in his honor is launched from the Kennedy Space Center and catapulted to the sun’s corona.
