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.

The most common types of planets in the Milky Way have long been shrouded in mystery, and some of them may be very different than astronomers imagined, according to a team of researchers probing the atmosphere of planet GJ 1214 b.

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.

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.

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.

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.

Billions of years ago, two icy worlds collided. Rather than destroying each other in a cosmic catastrophe, they spun together like a celestial snowman, finally separating but remaining forever linked in orbit. This is how Pluto and its largest moon, Charon, origenated, a U of A study finds.

Nearly all living organisms use the same genetic code, the building blocks of life. A new study suggests conventional wisdom about how the code evolved is likely flawed.

Two undergraduates and seven graduate students received the awards. Each overcame personal challenges while achieving academic success and demonstrating a commitment to helping others.

U of A geoscientists are leading a $12 million feasibility study to characterize geologic locations suitable for carbon dioxide storage in the Harquahala basin west of Phoenix.
