New lasers for a gigantic virtual telescope – a new era for interferometry

We’ve been working towards this for decades, and now the time has finally come. Last week, ESO’s Paranal Observatory was host to a show unlike any other as four lasers, one from each of the 8-metre telescopes of the Very Large Telescope (VLT), were projected into the skies. All in the name of science, of course. In this Chasing Starlight episode, we’ll explore GRAVITY+, a massive upgrade to ESO's VLT Interferometer and how new lasers are opening up the southern sky to this facility.
