The Einstein Telescope is being built around 250 meters underground. With interferometers in the three tunnels, each ten kilometers long, it will measure collisions of black holes in the early universe.

Unlocking a New Era in Astronomy From 250 Meters Underground

The Einstein Telescope, set to begin observations in 2035, will expand our capability to detect gravitational waves, offering new insights into the universe’s most dramatic events, including neutron star collisions that form elements like gold

How the Universe Makes Gold

The summer of 2017 had an extremely exciting day for astronomers: On August 17, three gravitational wave detectors registered a new signal. Hundreds of telescopes around the world were immediately pointed at the suspected point of origin and a luminous celestial body was indeed seen there. For the first time, the collision of two neutron stars was detected both optically and as a gravitational wave.
