Studying the Chemistry of the Universe with ALMA

  Combining the cutting-edge capabilities of the ALMA telescope with newly-developed laboratory techniques, scientists are opening a completely new era for deciphering the chemistry of the Universe. A research team demonstrated their breakthrough using ALMA data from observations of the gas in a star-forming region in the constellation Orion. Hubble’s sharpest view of the Orion [continue reading]

Hunting Exoplanets with Laser Rulers

  Laser frequency combs can be used for the calibration of astronomical spectrographs. This will help to find extra-solar planets, i.e. planets that are orbiting a star outside our solar-system. By refining this technology it might become possible to directly measure even very small changes in the expansion velocity of the universe.   Artist’s impression [continue reading]
