Center for Astrophysics An infrared view of NGC6334, the Cat’s Paw Nebula, a giant, star-forming molecular cloud. New submillimeter observations of the southern dark complex in this cloud have uncovered the first prestellar cores (embryos of future stars) ever found in a massive cloud, but they are very cold and cannot be seen in infrared images like this one. ESO/J. Emerson/VISTA Stars form as gravity contracts the gas and dust in an interstellar cloud until cores develop that are dense enough to coalesce into stars. A dense core in the earliest phase of this process is called a starless core, and if it has begun to collapse into a star the stage is referred to as a prestellar core. Prestellar cores can form single or multiple stars under the combined effects of gravity, magnetic fields, and turbulent motions, and understanding these and other properties of prestellar cores is critical to understanding star formation. Prestellar cores in low-mass molecular clouds ha ....
Massachusetts Institute of Technology The advance could cut production costs and reduce the size of microelectronics for sensing and communication. MIT researchers have developed a bright, efficient silicon LED, pictured, that can be integrated directly onto computer chips. The advance could reduce cost and improve performance of microelectronics that use LEDs for sensing or communication. Courtesy of the researchers Courtesy of the researchers Light-emitting diodes – LEDs – can do way more than illuminate your living room. These light sources are useful microelectronics too. Smartphones, for example, can use an LED proximity sensor to determine if you’re holding the phone next to your face (in which case the screen turns off). The LED sends a pulse of light toward your face, and a timer in the phone measures how long it takes that light to reflect back to the phone, a proxy for how close the pho ....
