Astronomical spectroscopy with unmatched precision

In the hunt for Earth-like exoplanets – Earth analogues in distant solar systems – astronomers rely on highest precision spectrographs in order to detect the minute Doppler shift in the spectrum of their host stars. The shift is caused by the reflex motion of the star around the common center of mass in the planet-star-system … Read more Astronomical spectroscopy with unmatched precision

Spectroscopy: A fine sense for molecules

Scientists at the Laboratory for Attosecond Physics have developed a unique laser technology for the analysis of the molecular composition of biological samples. It is capable of detecting minimal variations in the chemical make up of organic systems. At the biochemical level, organisms can be thought of as complex collections of different species of molecules. … Read more Spectroscopy: A fine sense for molecules
