Caltech physicists, engineers, and other faculty and students across campus soon will be able to come together in a collaborative, state-of-the-art space designed specifically to inspire and enable breakthroughs in quantum science and…

NASA's Lunar Trailblazer is nearing completion now that its second and final cutting-edge science instrument has been added to the small spacecraft. Built by the University of Oxford in England and contributed by the UK Space Agency, the…

This year, social media channels were suddenly flush with artistic images generated by the Midjourney software, which builds artworks based on nothing more than a text prompt. Text-generating software such as ChatGPT, meanwhile, can write…

Billions of years ago, in the giant disk of dust, gas, and rocky material that orbited our young sun, larger and larger bodies coalesced to eventually give rise to the planets, moons, and asteroids we see today. Scientists are still…

As stars like our sun swell in size with age, they can become large enough to engulf their inner planets. In May of this year, astronomers used the Zwicky Transient Facility, or ZTF, at Caltech's Palomar Observatory to catch one such…

A new technology being pioneered at Caltech is allowing researchers to "evolve" optical devices and then print them out using a specialized type of 3D printer. These devices are made of so-called optical metamaterials that derive their…

For the fourth year in a row, Caltech hosted active-duty military and veterans who want to prepare for a transition to undergraduate study in STEM fields.Under the auspices of the Warrior-Scholar Project (WSP), founded in 2012 "to propel…

In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of hydrogen, while the other is made up of…

Caltech and Carnegie Science have formalized a partnership to advance life and environmental sciences research in Pasadena, further strengthening the city's reputation as a hub for high-impact innovation and discovery. The agreement,…

Sweat, like blood, can tell us a lot about a person's health. And conveniently, it's a lot less invasive to collect. This is the premise behind the wearable sweat sensors developed by Wei Gao, assistant professor of medical engineering,…
