In 1969, UA scientists were the first to detect the optical flash from a pulsar — a stellar corpse thought to pack at least one-and-a-half times the mass of our sun into a neutron star.
Our Milky Way's largest neighbor, the Andromeda Galaxy, spans about 220,000 light-years across. Two of its dwarf satellite galaxies, Messier 110 (bottom left) and Messier 32 (above Andromeda's central bulge), are visible as bright white spots in this image taken by UA astrophotographer Adam Block.

Pinning down the mass of a galaxy may seem like an esoteric undertaking, but UA scientists think it holds the key to unraveling the nature of dark matter and the fabric of our cosmos.
UA undergraduate Adriana Mitchell will travel to Japan this summer to work on Hayabusa2, an asteroid sample return mission that is a sister project to the UA-led OSIRIS-REx mission.

Space is more congested, contested and dangerous than ever, and UA researchers are using $6.65 million in new funding to make it more secure for the nation's satellites.
This image of Mercury was created using infrared, red and violet filters that capture wavelengths both visible and invisible to the human eye; the colors shown here are only slightly different from what the human eye would see.

Michael Sori, a planetary scientist at the University of Arizona, used careful mathematical calculations to determine the density of Mercury’s crust, which is thinner than anyone thought.

A manned mission to Mars can succeed only if no vital parts of the system break beyond repair — including those that are human. Technology will need to address issues before they occur, says UA professor Wolfgang Fink. With UANews video. The series Fast Forward is examining the UA's role in the convergence of the digital, physical and biological worlds.

A worldwide collaboration will work on ways of processing unprecedented amounts of data in real time, with a primary goal of assisting the effort to take the first-ever pictures of a black hole. However, applications eventually could include self-driving cars, renewable energy and national defense.
