The main function of a telescope spectrograph is to separate light into its component colours (or wavelengths) to reveal information about the chemical content, temperature and motion of distant ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

The RISTRETTO project, dedicated to observing Proxima b –the closest exoplanet to the Solar System — is reaching a new milestone: several key components of this high-precision spectrograph have been ...
