The Department of Physics and Astronomy

We provide students a complete and rigorous undergraduate education in physics culminating in a Bachelor of Science degree. Our curriculum provides the ideal preparation for physics or engineering graduate school, careers in scientific research, or professions as educators. We are a dedicated faculty that is passionate about teaching and we are committed to the meaningful involvement of undergraduates in research. With small class sizes and varied research opportunities, we offer a unique learning opportunity for students interested in the natural sciences.

Total Lunar Eclipse Viewing Event

A total lunar eclipse will be visible across the United States on Sunday, January 20th. This will be the last total lunar eclipse anywhere in the world until 2021 and the last one visible in Colorado until September, 2025. If you would like to view the eclipse through a telescope, you can join members of the University of Northern Colorado Physics and Astronomy department at a special eclipse viewing session at the UNC Astronomy Lab.

UNC Astronomy Outreach

Prof. Mariana Lazarova and her intrepid Astronomy 100 students held a massively successful outreach event for 100 local 4th grade students at the University Center. Students took part in fifteen activities on topics ranging from the sun, the moon, and the galaxy, to filtered light, rockets, dark matter, and climate change.

Bears Go Big

UNC Bears go out into the world to do BIG and significant work. Meet Adam Wilson, Founder of Sphero and a 2010 UNC Physics Alum.

UNC helped me prepare for my success [and] gave me the opportunity to participate in undergraduate research.

See other Bears going big.
