Astronomers model, determine how disk galaxies evolve so smoothly

September 25, 2020

Using advanced computer simulations, scientists from UW, Iowa State and IBM are learning how galaxies get their characteristic structure — super-bright centers fading away to dark edges.

Massive halo finally explains stream of gas swirling around the Milky Way

September 9, 2020

Astronomers have solved a 50-year-old puzzle, discovering that the halo of warm gas surrounding the Magellanic Clouds likely acts as a protective cocoon.

Comet watching at Pine Bluff

July 24, 2020

Mysterious cloud ‘absorbers’ seen to drive Venusian albedo, climate

August 26, 2019

A better picture of the weather on Venus and how it is influenced by changes in the reflectivity of the clouds has emerged, thanks to new research.

Astronomer Snezana Stanimirovic named a 2019 Guggenheim Fellow

April 12, 2019

Stanimirovic uses both radio and infrared astronomy to address questions about star formation in and around the Milky Way by probing the properties of interstellar gas.
