NASA’s Juno mission has produced the first measurements of the temperature below the surface of Io, the most volcanically active world in the solar system, in a study whose lead author works at NASA’s Jet Propulsion Laboratory in Pasadena. The measurements rev... More »
Two new multi-institution collaborations led by Caltech scientists have been selected to receive first-round funding from the U.S. Department of Energy (DOE) as part of the Genesis Mission, a national effort to use AI to accelerate scientific discovery. The fi... More »
NASA’s newest class of suborbital Earth science missions is preparing for flight, with the first mission set to study dangerous wildfire-generated storm clouds using aircraft-mounted instruments, including infrared wildfire trackers developed by Jet Propulsion... More »
New research led by scientists at NASA’s Jet Propulsion Laboratory in Southern California has revealed the identity of a puzzling near-Earth object by precisely tracking its motion through space and using powerful observatories that image faint celestial objec... More »
Somewhere between the sunlit surface of the ocean and the dark floor thousands of feet below, a quiet snowfall is always underway. Not ice crystals, but clumps of dead algae, bacterial mucus, and organic debris — marine snow, the ocean’s slow-motion conveyor b... More »
NASA’s Perseverance rover, built and operated by Jet Propulsion Laboratory in Pasadena, has found evidence that repeated asteroid strikes helped construct a 245-foot-thick sequence of rocks on the rim of Mars’ Jezero Crater more than 3.9 billion years ago. The... More »
Two phrases now shape every serious conversation about quantum computing — when it will arrive, what it can do, how close the machines are to working. Both were coined by the same person, in the same building, on a campus a few blocks from Colorado Boulevard. ... More »
The last time NASA’s Jet Propulsion Laboratory invited the public inside, every ticket was gone before most people had finished their morning coffee. That was 2023. Three years, four rounds of layoffs, a wildfire evacuation and a 90th birthday later, JPL is do... More »
More than a year after the 2025 Los Angeles fires, Caltech labs are pressing forward with research projects to provide answers in service of public health and safety. Through investigations such as testing for heavy metal contamination, monitoring air quality,... More »
The rise of automation and AI has raised fears about job loss, but a team led by Caltech medical engineers suggests that smart tools can help train and assist workers rather than replace them. The team has developed a low-cost device that trains and assists pe... More »
Before the Omicron variant appeared in nasal swabs and PCR results, it was already flowing through the sewers — and Smruthi Karthikeyan found it there. Karthikeyan, a Caltech assistant professor whose wastewater surveillance work helped detect emerging COVID-... More »
The Nancy Grace Roman Space Telescope is at Kennedy Space Center in Florida right now, being prepped for an August 30 launch. Five weeks before liftoff, Lee Armus will try to explain what it can do — in 30 minutes, to anyone who walks through the door. Armus, ... More »
