New research by a UArizona undergraduate finds that asteroid 16 Psyche, the target of an upcoming NASA mission, may not be as metallic or dense as predicted.
After nearly five years in space, the OSIRIS-REx spacecraft is on its way back to Earth with an abundance of rocks and dust from asteroid Bennu.
Scientists are certain dark matter exists, but after more than 50 years of searching, they're still unsure what it's made of. A UArizona optical scientist proposes repurposing existing tabletop technology to search for dark matter.
Mission scientists will compare the final shots of the asteroid Bennu with images taken before the touch-and-go maneuver, which kicked up dust and rocks.
Before departing for Earth on May 10, the OSIRIS-REx spacecraft will perform a final flyby of Bennu – capturing its last images of sample collection site Nightingale.
On May 10, the OSIRIS-REx spacecraft will depart asteroid Bennu and begin its two-year journey back to Earth, where scientists will study the dust and rocks it collected from the asteroid's surface.
Planetary scientists wondered if bands of winds or swirling storms dominated the atmospheres of brown dwarfs. UArizona-led research solved the mystery.
Mars once had oceans but is now bone-dry, leaving many to wonder how the water was lost. New research suggests that the water escaped not like a leaky faucet, but with a sudden splash.
The OSIRIS-REx spacecraft successfully collected a large sample from the asteroid Bennu. But because some large pieces of rock are keeping the sample head from fully closing, the team has decided to expedite the stowing process.
