WAUSAU — Is mankind alone in the universe? Or are other intelligent beings looking up into their night sky from very different worlds asking the very same kind of question?

At 10 a.m. today, Jan. 23, Wisconsin Public Radio’s “Route 51” host Shereen Siewert welcomes astronomer and astrophysicist Margaret “Maggie” Turnbull to discuss the most recent efforts to find Earthlike planets and other forms of intelligent life throughout the universe.

Turnbull, who lives in Antigo, will talk about her experience as part of the Hubble Space Telescope team and as a consultant for NASA’s New Worlds Observer, a mission that maps planetary systems and searches for habitable planets and looks for signs of life.

“Route 51” is heard Thursdays at 10 a.m. on The Ideas Network stations 101.3 & 91.9/Wausau, AM 930/Auburndale-Stevens Point, 99.1/Stevens Point, 100.9/Marshfield, 90.3/Park Falls, 89.1/Adams-Wisconsin Rapids, and 89.9/Rhinelander-Eagle River. It is re-broadcast Fridays at 7 p.m. on 90.9/Wausau. Program archives are available at wpr.org/route51.
