News Near-Earth Asteroid Might be a Lost Fragment of the Moon Nov. 11, 2021 A research team led by LPL graduate student Ben Sharkey thinks that the near-Earth asteroid Kamo`oalewa might actually be a miniature moon. Read more Image Addy Graham/University of Arizona Plumes on Icy Worlds Hold Clues About What Lies Beneath Dec. 16, 2020 A new model shows how brine on Jupiter’s moon Europa can migrate within the icy shell to form pockets of salty water that erupt to the surface when freezing. The findings are important for the upcoming Europa Clipper mission and may explain cryovolcanic eruptions across icy bodies in the solar system.
