Eureka Alert on Dark Stars
Stars powered with dark matter still need proving but could reveal clues about the nature of one of the universe’s great mysteries
Science News: Dark Stars article by Skyler Ware
A trio of astrophysicists, two from Colgate University and the third from the University of Texas, has found evidence of dark stars courtesy of data from the James Webb Space Telescope. In their study, reported in Proceedings of the National Academy of Sciences, Cosmin Ilie, Jillian Paulin and Katherine Freese, analyzed three galaxies spotted by […]

The first stars of the universe were very different than the stars we see today. They were made purely of hydrogen and helium, without heavier elements to help them generate energy in their core. As a result, they were likely hundreds of times more massive than the sun. But some of the first stars may […]

Princeton Alumni Weekly, Newsmakers Q&A: Physicist Katherine Freese 77 on the Dark Big Bang
Katherine Freese ’77, a physicist at the University of Texas, Austin, has proposed that dark matter wasn’t created in the Big Bang along with all other matter, but rather in a second Big Bang some weeks later. Freese, who was recently elected to the National Academy of Sciences and serves as director of the Weinberg […]

Popular Science, “Dark energy fills the Cosmos. But What is it?”
The universe has a dark side—it’s filled with dark matter and dark energy. Dark matter is the unseen mass floating around galaxies, which physicists have searched for using giant vats of ice, particle colliders, and other sophisticated techniques. But what about dark matter’s stranger sibling, dark energy?
