VLT optics provide key to Relativity breakthrough

An effect predicted by Einstein’s Theory of General Relativity has for the first time been observed around a supermassive black hole, thanks in large part to cutting-edge optics and photonics technology.

Astronomers using the Very Large Telescope (VLT) facility at the European Southern Observatory (ESO) in Chile used adaptive optics and interferometric techniques to follow a star (known as “S2”) orbiting close to the center of our own Milky Way galaxy. The latest results are the culmination of some 26 years of observations, using increasingly advanced techniques.
