OSIRIS-APEX, the spacecraft that originally flew as OSIRIS-REx, is expected to reach the asteroid Apophis in late spring of 2029, but the team is already keeping the spacecraft busy.

A Jupiter-sized world just 7.5 light-years away is cloudy, chemically complex, and, it turns out, more like home than anyone expected.

The mission, dubbed PUFFINS, will use an ultraviolet space telescope to seek answers about dust between stars.

Contrary to conventional wisdom holding that early galaxies were composed of mostly hydrogen and helium, new observations suggest that galaxies were seeding the cosmos with heavy elements just 500 million years after the Big Bang.

The U of A ranks No. 1 in the Southwest and No. 1 in the Big 12 Conference in a new ranking that measures how central each university is in the global research-collaboration network.

Historically, computer simulations modeling collisions between protoplanetary bodies have treated them largely as fluids. A new study suggests taking into account the material strength of solid bodies drastically changes outcomes.

The launch of the Nancy Grace Roman Space Telescope takes place live Sunday morning at 7:26 am EDT/4:26 am MST on NASA Live.

Few space missions are run from university campuses. NASA's Pandora space has embarked on its mission to stare at worlds outside of our solar system and their host stars, all under the watchful eyes of a dedicated team at the U of A's own mission control center.

"Stunning" JWST images of newborn-solar systems shed light on how and when they lose gas, suggesting that planet formation is "a race against time," according to new research led by U of A graduate student Naman Bajaj.

New observations of unprecedented detail reveal that one of the most enigmatic asteroids in the solar system has a one-of-a-kind shape and is orbited by a previously unknown moon.
