NASA's newly launched SPHEREx mission will use software developed at the Arizona Cosmology Lab to analyze data and help astronomers understand what happened in the first trillionth of a second after the Big Bang.

U of A astronomers are learning more about a galaxy that existed when the universe was just 2% of its current age. One unexpected finding: significant amounts of oxygen.

The U.S. Giant Magellan Telescope and the European Extremely Large Telescope, both under construction in Chile, could transform scientists' quest for life beyond Earth.

Researchers at the University of Arizona have discovered that planet-forming disks of gas and dust around tiny stars live much longer than previously thought. The findings provide new insights into planet formation and the habitability of planets outside our solar system.

An advanced imaging system developed at the University of Arizona boasts a shape-shifting mirror that delivers observing details typically reserved for space-based telescopes.

"Universe of Science" is an interactive exhibit that explores everything from microscopic worlds to monsoon storms to the farthest reaches of deep space.

U of A astronomers have now produced the highest resolution direct images ever taken of a supermassive black hole in the infrared.

New observations led by a U of A astronomer suggest that even dwarf galaxies can accrete mass from other small galaxies, challenging a long-held theory about dwarf-galaxy expansion.

Three newly discovered dwarf galaxies in an isolated region of space show evidence of star formation being cut short by events in the early universe.

Taking advantage of a cosmic "double lens," astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.
