The Kavli Foundation hosted a Q&A with three astronomers to probe the recent discovery of hard-to-produce heavy elements in a nearby dwarf galaxy. The discovery sheds light on stellar histories and galactic evolution.
Are you interested in knowing what happened a long time ago in galaxies far, far away? Cosmology is big-picture astronomy — it’s how we understand the universe on its grandest scales. From the mysteries of dark matter and dark energy to the vast cosmic web, modern cosmology probes what makes the cosmos tick.
Here you’ll find Sky & Telescope’s coverage of the latest discoveries in cosmology. Want to know more about the Big Bang? What about the ongoing controversy over the current expansion rate of the universe? What can we learn about galaxy formation at the very beginning? We bring you in-depth reports on the early universe, ancient galaxies, and the cosmic microwave background, the leftover glow of radiation released after our universe’s birth. As scientists peer further back in time and space, pushing the limits of the knowable, we’ll be your guides on the quest to reach the cosmic dawn.
