The brightest comet of the year, named after the UArizona researcher who discovered it, is paying one last visit to Earth's neighborhood before leaving the solar system forever.

A team led by UArizona astronomers will use NASA's James Webb Space Telescope to examine three of the most distant active supermassive black holes known, as well as their host galaxies.

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.

UArizona astronomers used massive galaxy clusters as natural magnifying glasses to discover strange galaxies that stopped making stars before their time. 

Analyzing observations of an X-ray flare and fitting the data with theoretical models, astronomers documented a fatal encounter between an unlucky star and a black hole.

UArizona is providing the software hub for the NEID spectrometer on Kitt Peak as the instrument begins its mission to discover Earth-like planets elsewhere in the Milky Way.

Researchers used detailed observations of an enormous jet of glowing gas and dust to pinpoint the supermassive black hole at the center of galaxy Centaurus A.
