Caltech scientists are actively studying how to seamlessly integrate technology—things like sensors, actuators, and microprocessors, but also novel materials—into things that we wear. And the social media and technology company Meta Platforms, Inc. (Meta), has... More »
Across the cosmos, many stars can be found in pairs, gracefully circling one another. Yet one of the most dramatic pairings occurs between two orbiting black holes, formed after their massive progenitor stars exploded in supernova blasts. If these black holes ... More »
The Atlantic meridional overturning circulation, commonly referred to as the “AMOC,” is a system of ocean currents confined to the Atlantic basin that plays a crucial role in regulating Earth’s climate by transporting heat from the Southern to the Northern Hem... More »
Jet Propulsion Laboratory will transition to full-time, in-person work by late October, marking a significant shift in the laboratory’s post-pandemic operational model. In an internal communication dated May 22, from the JPL Director’s Office, leadership addre... More »
A powerful sonic boom from SpaceX’s returning Dragon spacecraft rattled windows and shook buildings across Pasadena on Saturday evening, May 24, 2025, prompting confused residents to flood social media with reports of the mysterious sound. The sonic boom occur... More »
Manuel Endres, professor of physics at Caltech, specializes in finely controlling single atoms using devices known as optical tweezers. He and his colleagues use the tweezers, made of laser light, to manipulate individual atoms within an array of atoms to stud... More »
The Los Angeles region has some of the most polluted air in the United States, failing to meet standards set by the Environmental Protection Agency for the last decade. Now, Caltech researchers have quantified the levels of a component of smog called ammonium ... More »
Understanding Jupiter’s early evolution helps illuminate the broader story of how our solar system developed its distinct structure. Jupiter’s gravity, often called the “architect” of our solar system, played a critical role in shaping the orbital paths of oth... More »
NASA JPL’s Perseverance Mars rover is exploring a new region of interest the team is calling “Krokodillen” that may contain some of the oldest rocks on Mars. The area has been on the Perseverance science team’s wish list because it marks an important boundary ... More »
Cheyanne E. Shariat, a graduate student in astrophysics, and Laura Lewis (BS ’23), a Caltech alumna in math and computer science, have been named among 30 recipients of this year’s Department of Energy Computational Science Graduate Fellowship (DOE CSGF), an h... More »
? Small autonomous underwater vehicles, like the drones of the sea, could be very useful for studying the depths of the ocean and monitoring its changing conditions. But such nautical mini bots can be easily overpowered by turbulent ocean currents. Caltech sci... More »
Sometimes, only a 50-year-old laser will do. Nick Hutzler (BS ’07), an assistant professor of physics at Caltech, says the Coherent 599 tunable dye laser in this photograph, which was manufactured in 1977, is a surprisingly useful tool for an initial step in h... More »
