Finding reveals how starlight drives surprising chemistry, offers new way to study alien atmospheres

Study led by UChicago researchers uses bending by gravity of the oldest light in the universe to map the intervening structure

UChicago scientists offer new way to read atmospheric data on a vast class of 'sub-Neptune' worlds

Detection by Askaryan Radio Array holds promise for future research into sources, nature of cosmic rays and neutrinos

On trip to Chilean telescope, UChicago undergrad class sheds new light on evolution of earliest stars

Still in its original galaxy, a rare holdout from the second generation of stars sheds new light on the origins of the elements—and how massive supernovae reshaped the cosmos

Unique UChicago-led instrument PUEO caught a ride aboard a NASA balloon in search of high-energy neutrinos

XRISM satellite allows UChicago scientists to directly detect turbulence driven by Perseus, M87 black holes

Donald G. York, an astronomer with the University of Chicago who helped revolutionize the field as a co-founder of the Sloan Digital Sky Survey and made pioneering contributions to the study of the interstellar and intergalactic mediums, died Dec. 26 at the age of 81.  

Faraway planet defies our understanding of planet formation, say UChicago scientists

A new technique gives astronomers — and the public — a different look at some of the largest objects in the universe. Developed using NASA’s Chandra X-ray Observatory data, “X-arithmetic” classifies galaxy clusters and groups by their nature rather than appearance.

UChicago astrophysicists test a new piece of the sky to probe dark matter and dark energy

Research led by UChicago’s Eliza Kempton finds some ‘mini-Neptunes’ likely have solid surfaces rather than molten interiors

Pioneering cosmologist honored for landmark measurements of the Hubble Constant

An exoplanet is what we call planets that exist outside of our own solar system. The first one was discovered in 1992, but as we get more powerful and precise telescopes and instruments, scientists have been discovering more and more of these faraway planets—about 6,000 of them so far. But scientists think there are trillions more out there in the universe.
