DESI is an unprecedented effort to map millions of galaxies and quasars to better understand the nature of dark energy – the mysterious force that has pulled the universe apart since the Big Bang.

Researchers have discovered a region just beyond Jupiter that acts as a "comet gateway," funneling icy bodies from deep space into the inner solar system.

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.

Ten students from Japan and Arizona gathered for the first official Space Camp Biosphere 2, where they designed Biosphere 3 to sustain human life on Mars.

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.
