Failed star creates its own spotlight in the universe
Newark DE (SPX) Jun 15, 2016
Although astronomers often refer to brown dwarfs as "failed stars," scientists at the University of Delaware have discovered that at least one of these dim celestial objects can emit powerful flashes of light. A research team led by John Gizis, professor in UD's Department of Physics and Astronomy, discovered an "ultracool" brown dwarf known as 2MASS 0335+23, with a temperature of only 4400 F that can generate flares stronger than the sun's. Gizis reported on the finding on June 13 at the annual m ... read more

Optical 'sonic boom' could help graphene convert electricity into light
Researchers have discovered a new way to create a strong and focused beam of light using graphene. The technique uses a phenomenon called an "optical boom" - named after the auditory phenomenon known as the sonic boom, which is caused by an object like an airplane traveling faster than the speed of sound. ... more
