From One Collapsing Star, Two Black Holes Form and Fuse

Black holes—massive objects in space with gravitational forces so strong that not even light can escape them—come in a variety of sizes. On the smaller end of the scale are the stellar-mass black holes that are formed during the deaths of stars. At the larger end are supermassive black holes, which contain up to one billion times the mass of our sun. Over billions of years, small black holes can slowly grow into the supermassive variety by taking on mass from their surroundings and also by merging with other black holes.

qCraft Introduces Gaming Kids to Quantum Principles

Finding common ground between schoolchildren and quantum-mechanics researchers is no easy task. After all, understanding quantum mechanics—the physics that governs the behavior of matter and light at the atomic (and subatomic) scale—can be daunting even for some physicists. However, through a recent collaboration with Google, researchers at Caltech have created a new space for this unlikely interaction—in the world of Minecraft, a popular video game.

Caltech Nobelist Zewail Named to UN Scientific Advisory Board

Ahmed Zewail, Linus Pauling Professor of Chemistry and professor of physics, has been selected as one of 26 members of a new U.N. Scientific Advisory Board.

Reducing Coincidence with Mathematics: An Interview with Nets Katz

Raised in Grand Prairie, Texas, Nets Katz began pursuing mathematics at an early age, earning a bachelor's degree at the age of 17 and a doctorate at 20. He joined the faculty at Caltech in January 2013.

Sky Survey Captures Key Details of Cosmic Explosions

Astronomical surveys have been cataloguing the night sky since the beginning of the 20th century. The intermediate Palomar Transient Factory (iPTF)—led by Caltech—started searching the skies for certain types of stars and related phenomena in February. Two recent papers by iPTF astronomers describe first-time detections.

Let There Be Light: Finding the Earliest Galaxies

Richard S. Ellis, the Steele Family Professor of Astronomy, is on the verge of seeing as far back as it is possible to see—not quite back to the dawn of time itself but to the dawn of the first galaxies. He describes the journey at 8 p.m. on Wednesday, October 16, in Caltech's Beckman Auditorium. Admission is free.
