The Event Horizon Telescope (EHT) -- a planet-scale array of eight ground-based radio telescopes forged through international collaboration -- was designed to capture images of a black hole. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.

Since its inauguration in 1969, ESO’s La Silla Observatory has been at the forefront of astronomy. Its suite of state-of-the-art instruments has allowed astronomers to make ground-breaking discoveries and paved the way for future generations of telescopes.

ESO is celebrating the twentieth anniversary of one of the VLT’s most versatile instruments, the FOcal Reducer and low dispersion Spectrograph -- FORS2.

Hidden in one of the darkest corners of the Orion constellation, this Cosmic Bat is spreading its hazy wings through interstellar space two thousand light-years away.

In this ESOcast, six astronomers tell us about the hottest topics in contemporary astronomy. Covering topics ranging from dark matter to exoplanets, these astronomers make the case for why these cutting-edge fields deserve time at ESO's telescopes.
