Man Enters the Cosmos is a cast bronze sculpture by Henry Moore located on the Lake Michigan lakefront outside the Adler Planetarium in the Museum Campus area of downtown Chicago, Illinois.

[2][3] The sundial was formerly located slightly further south at the steps of the main entry plaza to the Planetarium,[4][5] but it now sits directly on the lakefront.

The work is a later copy of a composition first created in the 1960s for the offices of The Times newspaper at Printing House Square in London, and according to the Henry Moore Foundation is titled Sundial 1965–66.

[6] The Adler Planetarium, in the Museum Campus area of downtown Chicago, Illinois,[4][2] is both a National Historic Landmark and listed on the National Register of Historic Places, and is located in the Near South Side community area of Chicago.

Many of the Ferguson fund's commissioned works, such as the Fountain of the Great Lakes, are housed in and on the grounds of the Art Institute of Chicago or elsewhere in Grant Park.

The bowstring equatorial sundial derives its name from the appearance of the shadow-casting gnomon, which resembles a bow string.

[2] Over the course of the year different sections of the rod serve as the style, which is the part of the gnomon that indicates the time by casting its shadow on the dial face.

[12] This construction was contemporaneous with the $100 million project that reconfigured of traffic around the Museum Campus and caused Lake Shore Drive to be moved during the mid-1990s.
