Globular clusters have puzzled astronomers with the presence of different distinct populations of stars; is dark matter a possible solution to this problem?
In the latest of our #UndergradResearch series, discover how Emily Silich used observations from the HaloSat cubesat to search for X-ray signatures of dark matter.
How can the first stars tell us about the nature of dark matter?
Today we interview Dr. Scott Tremaine, who is giving the career-capping Henry Norris Russell lecture, which will feature insights into cosmic dynamics on scales ranging from comets to galaxy clusters.
We report on Day 1 of the virtual winter AAS meeting.
Thanks to the Gaia satellite and other incredible data sources, we are in for a set of unprecedented discoveries about our galaxy over the next few years. Learn more about them at Dr. Adrian Price-Whelan’s talk at #AAS237!
