ESO's VLT Working as Single Huge Telescope for First Time
ESO's Very Large Telescope can now work as a 16-metre telescope — fulfilling the original very large dream...
The ESPRESSO instrument has combined the light from all four of the VLT's 8.2-metre Unit Telescopes.
The light from each telescope is collected at an "incoherent focus"...
...making the VLT the largest ever optical telescope by collecting area.
With the four Unit Telescope working together, ESPRESSO will search for Earth-like planets and shed light on fundamental physical constants.
What astronomers once dreamed of, has finally come true!
