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.
After years of preparation and anticipation, exoplanet researchers are ecstatic about the first official scientific observation of an exoplanet by NASA's James Webb Space Telescope. The results are indicative of Webb's ability to spot key molecules like carbon dioxide in a wide variety of exoplanets.
A newly discovered impact crater below the seafloor hints at the possibility that more than one asteroid hit Earth during the time when dinosaurs went extinct. UArizona researcher Veronica Bray, who specializes in craters found throughout the solar system, is co-author of a new study about the discovery.
University of Arizona students and faculty members completed a comprehensive study to track and characterize satellites, using a ground-based sensor they developed to measure satellites' brightness, speed and paths through the sky.
Before-and-after data from the few seconds it took the OSIRIS-REx spacecraft to collect a sample from asteroid Bennu revealed a surprise: The particles of Bennu's exterior are so loosely packed, they act more like a fluid than a solid.
UArizona scientists took part in an international planetary defense exercise that used asteroid Apophis – a large, potentially hazardous asteroid – to test the planetary defense response chain.
A new decadal survey from the National Academies of Sciences, Engineering, and Medicine recommends NASA fully support NEO Surveyor, a space-based survey designed to discover and measure asteroids and comets that could pose an impact hazard to Earth. Amy Mainzer, a professor of planetary sciences, leads the effort.
Plasma is rare on Earth, but it fills the sky. To more deeply understand this state of matter that makes up 99% of the visible universe, NASA's HelioSwarm mission will deploy a "swarm" of spacecraft to gather data. UArizona assistant professor Kristopher Klein will serve as the mission's deputy principal investigator.
For weeks, UArizona students have been gathering data on a high-profile piece of space junk on a collision course with the moon. They've confirmed it's not a SpaceX Falcon 9 rocket booster as previously believed.
Moons around terrestrial planets may play important roles in shaping the conditions for life. For sizable moons to form successfully, the circumstances must be just right, a new study finds.
