The early universe is filled with monsters, a new study reveals. Researchers discovered a previously invisible galaxy, and perhaps a new galaxy population waiting to be discovered.

Astronomy Prof Peter Behroozi was awarded a Packard Fellowship to get to the bottom of a long-standing mystery: How could supermassive black holes grow so big so quickly after the Big Bang?

Volcanism has always intrigued humanity. Less than 50 years ago, scientists discovered cryovolcanism – ice volcanoes on other worlds. Now, researchers may have identified volcanoes of molten metal.

University of Arizona researchers are using the Catalina Sky Survey’s near-Earth object telescopes to locate the optical counterparts to gravitational waves triggered by massive mergers.

The OSIRIS-REx spacecraft has mapped Bennu to identify the best spots for the spacecraft to collect a sample. The final two sites – a primary and backup – will be selected in December.

By creating millions of virtual universes and comparing them to observations of actual galaxies, a UA-led team present a powerful new approach for studying galaxy formation.

UA researchers have designed a telescope that is a cheaper, lighter and more powerful option than creating telescopes using ever-larger mirrors.

Two UA astronomers received Early Career Research Awards from the Department of Energy to to investigate the nature of the expanding universe and other dark mysteries.

Humans first explored the Earth’s moon 50 years ago, an impressive feat for sure. But what would it be like to visit some of the other moons in our solar system?

UA scientists were instrumental in creating the first photographic atlases of the moon, which helped NASA successfully complete the Apollo 11 mission. Now, UA scientists are busy mapping worlds throughout our solar system.
