The OSIRIS-REx spacecraft has mapped Bennu to identify the best spots for the spacecraft to collect a sample. The final two sites – a primary and backup – will be selected in December.
The Hubble Space Telescope took this image of Abell 370, a galaxy cluster 4 billion light-years from Earth. Several hundred galaxies are tied together by gravity. The arcs of blue light are distorted images of galaxies far behind the cluster, too faint for Hubble to see directly. (Image: NASA, ESA, and J. Lotz and the HFF Team/STScI)

By creating millions of virtual universes and comparing them to observations of actual galaxies, a UA-led team present a powerful new approach for studying galaxy formation.

UA researchers have designed a telescope that is a cheaper, lighter and more powerful option than creating telescopes using ever-larger mirrors.
Astronomers think that the expansion of the universe is regulated by both the force of gravity, which acts to slow it down, and a mysterious dark energy, which pushes matter and space apart at faster and faster speeds. In this artist's conception, dark energy is represented by the purple grid above and gravity by the green grid below. Gravity emanates from all matter in the universe, even dark matter.

Two UA astronomers received Early Career Research Awards from the Department of Energy to to investigate the nature of the expanding universe and other dark mysteries.
