Summary edit

Description
English: We have all looked up at the sky at night and seen the stars twinkle. It may be pretty and romantic, but it is also a big problem for astronomers, as the shimmering starlight blurs observations.

In this ESOcast we visit the Allgäu public observatory amid the picturesque landscape of southern Germany. Here, as night falls, a team of scientists and engineers prepares to field test a laser guide star unit, which will soon be on its way to ESO’s Paranal Observatory. This cutting edge technology can help astronomers cancel out the effects of the turbulence in the atmosphere and obtain much sharper views of the Universe.
