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.

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 »

LIGO detects gravitational waves from Neutron Star collision

An artist's rendering of the collision of two neutron stars

For the first time, physicists have detected gravitational waves from the collision of two neutron stars. The observation was made by LIGO, the Laser Interferometer Gravitational-Wave Observatory, a collaborative project with over one thousand researchers from more than twenty countries, including the University of Minnesota.
