Voyager: Getting to Know the Magnetic Highway

Since last August, NASA's farthest-flung robotic envoy, Voyager I, has been exploring a distant region just shy of interstellar space, some 11 billion miles (18 billion kilometers) away. Now, Voyager scientists, including Caltech's Ed Stone, are sharing what they have learned about the peculiar region known as the "magnetic highway."

Notes from the Back Row: "Quantum Entanglement and Quantum Computing"

John Preskill, the Richard P. Feynman Professor of Theoretical Physics, is hooked on quanta.

Birth of a Black Hole

According to a new analysis by astrophysicist Tony Piro at Caltech, just before a black hole forms, the dying star may generate a distinct burst of light that will allow astronomers to witness the birth of a new black hole for the first time.

Astronomers Discover Massive Star Factory in Early Universe

A team of astronomers, which includes several from Caltech, has discovered a dust-filled, massive galaxy churning out stars when the cosmos was a mere 880 million years old—making it the earliest starburst galaxy ever observed.

The Caltech Space Challenge: Mission to a Martian Moon

The mission: travel to one of Mars's two moons, explore its surface, collect some rocks, and return to Earth in one piece. Now plan it—in five days. Dozens of students from Caltech and around the world converged on campus recently to do just that.

Quantum Entanglement and Quantum Computing

John Preskill, the Richard P. Feynman Professor of Theoretical Physics, is himself deeply entangled in the quantum world. Different rules apply there, and objects that obey them are now being made in our world, as he explains at 8:00 p.m. on Wednesday, April 3, 2013, in Caltech's Beckman Auditorium. Admission is free.

Fifty Years of Quasars

In a paper published on March 16, 1963, Caltech astronomer Maarten Schmidt announced the discovery of the first quasar (he didn't call it that) and opened a new window through which we can see the very distant universe.

Two Decades of Discoveries

Although Keith Matthews was about to make history, he went about his tasks like any others. It was the night of March 16, 1993, nearly 14,000 feet above sea level on Mauna Kea in Hawaii, and he had just installed the first instrument on the brand-new 10-meter telescope at W. M. Keck Observatory. Matthews, who built the instrument—a near-infrared camera, abbreviated NIRC—was set to make the first scientific observations using the newly crowned Biggest Telescope in the World.

Bursts of Star Formation in the Early Universe

PASADENA, Calif.—Galaxies have been experiencing vigorous bursts of star formation from much earlier in cosmic history than previously thought, according to new observations by a Caltech-led team.

These so-called starburst galaxies produce stars at a prodigious rate—creating the equivalent of a thousand new suns per year. Now the astronomers have found starbursts that were churning out stars when the universe was just a billion years old. Previously, astronomers didn't know whether galaxies could form stars at such high rates so early in time.
