The Illinois State University Planetarium will present The Hot and Energetic Universe running weekends February 4-26. Showtimes are 7:30 p.m. Fridays and 2 p.m. and 7:30 p.m. Saturdays.

The Hot and Energetic Universe explores our cosmos using high-energy x-rays and gamma-rays from space. This energetic light allows modern astronomers to probe hidden phenomena found throughout our often hot and violent universe. Thus, we see the heated gas in clusters of galaxies, which are the most massive objects in the universe. We also observe hot gas accreting around supermassive black holes in the centers of galaxies. Finally, high energy radiation provides important information about our own galaxy — including neutron stars, supernova remnants, and stars like our Sun which emit copious amounts of high energy radiation.

After each program, we explore the highlights found in the current evening sky. These highlights include the bright stars, constellations, and planets visible from Central Illinois.

Admission to the Illinois State University Planetarium is $5 for adults; $4 for children ages 5-12, seniors, and ISU ID holders; and $3 for children ages 3-4. Cash or checks only.
