Two research publications by the OSIRIS-REx sample analysis team suggest that conditions for the emergence of life were widespread across the early solar system.

Some of the most common types of planets in the Milky Way may be very different than astronomers imagined, according to researchers probing the atmosphere of planet GJ 1214 b.

A paper by U of A associate professor Susan Swanberg explains how the Oscar-winning 1953 film, shot in Tucson, failed to live up to its claim as a "true-life adventure."

U of A astronomers have now produced the highest resolution direct images ever taken of a supermassive black hole in the infrared.

New observations led by a U of A astronomer suggest that even dwarf galaxies can accrete mass from other small galaxies, challenging a long-held theory about dwarf-galaxy expansion.

The exoplanet mission, which will study of at least 20 known planets orbiting distant stars, has cleared an important milestone with the completion of its spacecraft bus.

Three newly discovered dwarf galaxies in an isolated region of space show evidence of star formation being cut short by events in the early universe.

The grant from the National Institute for Occupational Safety and Health will support U of A researchers' work to improve safety and productivity in the mining industry.

Taking advantage of a cosmic "double lens," astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.
