New planet imager delivers first science at Keck



Pasadena CA (JPL) Jan 31, 2017
A new device on the W.M. Keck Observatory in Hawaii has delivered its first images, showing a ring of planet-forming dust around a star, and separately, a cool, star-like body, called a brown dwarf, lying near its companion star. The device, called a vortex coronagraph, was recently installed inside NIRC2 (Near Infrared Camera 2), the workhorse infrared imaging camera at Keck. It has the potential to image planetary systems and brown dwarfs closer to their host stars than any other instrument in the wor ... read more

When energy and nutrients abound, a bacterium will repair itself while synthesizing new parts to create a twin and then split, all as quickly as conditions allow. But if resources shrink, so does growth rate. The cell responds by shunting its dwindling supplies from replication to repair, shutting down processes until it's running a skeleton crew to survive. Below a crucial level, it's all over. ... more

Research pushes concept of entropy out of kilter
Entropy, the measure of disorder in a physical system, is something that physicists understand well when systems are at equilibrium, meaning there's no external force throwing things out of kilter. But new research by Brown University physicists takes the idea of entropy out of its equilibrium comfort zone. The research, published in Physical Review Letters, describes an experiment in which the ... more
