2012-03-08 04:03:29

If there is life on other planets, a laser frequency comb developed at the National Institute of Standards and Technology (NIST) may help find it. Such a comb–a tool for precisely measuring frequencies, or colors, of light–has for the first time been used to calibrate measurements of starlight from stars other than the Sun. The good results suggest combs will eventually fulfill their potential to boost the search for Earth-like planets to a new level. As described in Optics...

A new way of reading light will sharpen the view of planets around other stars Thanks to the ability of astronomers to detect the presence of extrasolar planets orbiting distant stars, scientists today are able to examine hundreds of solar systems. Now researchers at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. have created an "astro-comb" to help astronomers detect lighter planets, more like Earth, around distant stars. The Harvard group will present their findings at...
