Additionally, Caltech is making huge advances in two avenues of research that could produce a working quantum computer in the coming years: Machines that use neutral atoms as qubits, the quantum version of a classical bit, and those that use superconducting qubits.

The Voyager 1 and Voyager 2 space probes have traveled the farthest into space of any human creation. NASA hopes that a reworking of the aging spacecraft’s power systems could extend their nearly 50-year-old exploration of interstellar space into the early 2030s.

More than two decades before NASA was created, Caltech students and researchers worked side-by-side on daring rocketry experiments in the Arroyo Seco.

Today, Caltech students continue that legacy at JPL.

Every centimeter of sea-level rise could displace 1.5 million people, and current estimates of rise range from half a meter to 2 meters by the end of the 21st century—which means that potentially hundreds of millions of people could be affected.

New research from Caltech analyzing pieces of a meteorite has found that, in the same way that snowflakes crystallize around grains of dust, ancient stardust grains leftover from long-gone suns may have been the seeds of our solar system's earliest solids.
