Four growing seasons after the engineered spring flood of the Colorado River Delta in March 2014, the delta’s birds, plants and groundwater continue to benefit, according to an International Boundary and Water Commission report prepared by a UA-led team.

UA-led researchers mapped changes in snow from 1982 to 2016 over the contiguous U.S. and found parts of the West have had a 41 percent reduction in the yearly maximum snow mass.

Systems engineering and mathematics double major Keara Burke is helping NASA's OSIRIS-REx spacecraft find the perfect place to collect samples on the asteroid Bennu.
This mosaic image of asteroid Bennu is composed of 12 PolyCam images collected on Dec. 2 by the OSIRIS-REx spacecraft from a range of 15 miles (24 km). (Image: NASA/Goddard/University of Arizona)

Observations made by the spacecraft during its approach of Bennu reveal that the asteroid interacted with water in its early history and is an excellent specimen for the mission, which is slated to return a sample of surface material to Earth in 2023.
The Taurus Molecular Cloud, pictured here by ESA's Herschel Space Observatory, is a star-forming region about 450 light-years away. The image frame covers roughly 14 by 16 light-years and shows the glow of cosmic dust in the interstellar material that pervades the cloud, revealing an intricate pattern of filaments dotted with a few compact, bright cores — the seeds of future stars.

Since its launch on Sept. 8, 2016, OSIRIS-REx has spent two years catching up with asteroid Bennu on its orbit around the sun. The spacecraft's arrival at Bennu on Dec. 3 marks a major milestone, with the mission transitioning from flying toward the asteroid to orbiting around it.
