Astronomers have discovered a structure thought to be a "protocluster" of galaxies on its way to developing into a galaxy supercluster. The discovery was made possible, in part, by the UArizona-managed Large Binocular Telescope.

By combining Hubble Space Telescope observations with theoretical models, a team of astronomers has gained insights into the chemical and physical makeup of a variety of exoplanets known as hot Jupiters.

NASA's new flagship space observatory has arrived in French Guinea, where it will be readied for launch on Dec. 18. UArizona astronomers Marcia and George Rieke played key roles in designing and building the telescope's infrared "eyes," which will peer deeper into the cosmos than ever before. 

Using data from NASA's OSIRIS-REx mission, a UArizona-led team of scientists concluded that asteroids with highly porous rocks, such as Bennu, should lack fine-grain material on their surfaces.

New research into metal-rich asteroids reveals information about the origins and compositions of these rare bodies that could one day be mined.
