Brittany Miles has been named a 51 Pegasi b Fellow in Planetary Astronomy by the Heising-Simons Foundation. Brittany’s expertise lies in mid-infrared observations of brown dwarfs—astronomical objects that share properties with both planets and stars. As a Peg b Fellow at UArizona, Brittany will continue her observations of brown dwarf atmospheres to obtain data on cloud composition and behavior. As co-principal investigator on a James Webb Space Telescope proposal, she will explore the coldest known brown dwarf to inspect possible water clouds and water vapor and infer how such features may behave on gas giant exoplanets.

Sagan Fellow Dr. Feng Long joins LPL this Fall 2022. Dr. Long seeks to better understanding the earliest phase of planet formation and to shed light on the origin of the observed diversity in exoplanet properties. Her past works have demonstrated the prevalence of gap and ring features in disks, which are the likely imprints of young planets. At LPL, she will employ observational data from cutting-edge facilities to establish the impact of these disk features on planet formation and to study the associated young planet population.

Scientists have long debated what's under the surface of Mars' south pole. A new study points to clays being more likely than a subsurface lake.

Impact craters left by space debris in the boulders on asteroid Bennu's rugged surface allowed researchers to reconstruct the history of the near-Earth object in unprecedented detail.

The gravitational push and pull by Jupiter's moons could account for more warming than the gas giant Jupiter alone.

Dr. Michael Sori and Dr. Ali Bramson, Postdoctoral Scholars in the Lunar and Planetary Laboratory (LPL), both have recently accepted positions as Assistant Professors in the Department of Earth, Atmospheric, and Planetary Sciences (EAPS) at Purdue University.

The plane of the solar system is warped in the outer reaches of the Kuiper Belt, signaling the presence of an unknown Mars-to-Earth-mass planetary object far beyond Pluto, according to new research from the UA.
