Eta Car
< >

Two University astronomers, Kris Davidson and Roberta Humphreys have discovered that a massive binary star system, Eta Car is returning to its original state: that of a hot star easily visible in the sky of the Southern Hemisphere. Davidson and Humphreys have observed Eta Car since the Hubble Space Telescope first came online in 1990. This series of observations has given them solid evidence that Eta Car-- sometimes called the poster child for very massive stars, because it is the most massive star that is close enough to Earth to be easily observed—is experiencing dramatic changes.

SPS Named Outstanding Chapter

Levi Walls at the Family Fun Fair outreach event

The School's chapter of the Society of Physics Students (SPS) was named "Outstanding Chapter" by the national organization. Chapter President Levi Walls said that "despite being confined to Shepherd Labs due to the Tate remodel, SPS was able to increase the number of opportunities for members to volunteer within the department and community at large."

Minnesota space physicists make discovery that may help improve space weather predictions

Aaron Breneman

Dr. Aaron Breneman, researcher in the School of Physics and Astronomy, was lead author on a paper which helps explain the mechanism which causes highly energetic electrons that reach the Earth’s atmosphere. Such particles can cause the auroral displays--the Northern Lights in Northern Minnesota, for example, and can damage satellites and other spacecraft. One of the goals of this research is to help predict space “weather” which can adversely affect human activity and technology. More »
