The mystery of whether microbial alien life might inhabit Enceladus, one of Saturn's 83 moons, could be solved by an orbiting space probe, according to a UArizona-led study.

Black holes are surrounded by an invisible layer that swallows every bit of evidence about their past. Researchers are now using machine learning and supercomputers to reconstruct the growth histories of black holes.

Less than a year after the James Webb Space Telescope's Christmas Day launch in 2021, scientists have captured images of the most distant galaxies ever seen.

Thanks to the James Webb Space Telescope, scientists have identified a "mystery molecule" that previously stumped astronomers. They've also gained insights needed to interpret potential signs of habitability on other exoplanets.

To mark the lecture series' 100-year anniversary, an evening celebration will include a presentation on the newest science to come out of the James Webb Space Telescope, a chance to peer at the sky through telescopes, recognition of a new endowed chair and the opening of Steward Observatory's visitor center.

NASA's DART spacecraft will slam into an asteroid this month, and scientists will study how the impact affects its orbit around a larger, companion asteroid discovered by UArizona researchers in 1996.

The Large Binocular Telescope is unrivaled in the global arsenal of optical telescopes. Sporting two 27-foot mirrors made at UArizona, its unique design allows astronomers to make observations that would not otherwise be possible.
