But new observations of a nearby active galaxy called NGC 3783 harnessing the power of the Very Large Telescope Interferometer (VLTI) at ESO's Paranal Observatory in Chile 2 have given a team of astronomers a surprise.
In order to investigate the central regions of NGC 3783 the astronomers needed to use the combined power of the Unit Telescopes of ESO's Very Large Telescope.
Using these units together forms an interferometer that can obtain a resolution equivalent to that of a 130-metre telescope.
