CSE Distinguished Professor Roberta Humphreys likes them big – stars, that is. For many years her research has focused on the evolved, most massive stars and the unstable final stages before they explode as supernovae. These very massive and very large stars have relatively short lifetimes of a few million years. Near the ends of their lives, due to still poorly understood physics, they shed a lot of mass, and in many cases producing visible circumstellar nebulae as a record of their instabilities.


LIGO does it again: gravitational waves detected from second pair of colliding black holes

Vuk Mandic

On December 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves—ripples in the fabric of spacetime—for the second time. The gravitational waves were detected by both of the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. More »

Zooniverse takes on Civil War crowdsourcing project

Lucy Fortson

Associate Professor Lucy Fortson, a leader in the Zooniverse project, has helped develop a crowdsourcing technology to spark curiosity and develop critical-thinking skills among students. The latest project will be to transcribe and decipher nearly 16,000 Civil War telegrams between Abraham Lincoln, his Cabinet, and officers of the Union Army. Roughly one-third of the messages were written in code. More »
