BlackGEM Telescopes Commence Quest to Detect Gravitational-Wave Sources at ESO’s La Silla Observatory
The European Southern Observatory’s (ESO) La Silla Observatory in Chile has already made headlines by contributing to the discovery of the first exoplanet back in 1995. Now, the observatory is set to add another accolade to its list of accomplishments. BlackGEM – an international collaboration of research institutions and universities – has undertaken its mission to detect gravitational-wave sources using the La Silla Observatory. They hope to achieve their goal with an array of three 65-centimeter telescopes that forms the heart of this ambitious project.
BlackGEM Project Details and Vision
The BlackGEM project began in 2014 with the primary aim of installing a series of telescopes in the Southern Hemisphere to monitor the sky for transient phenomena such as supernovae and other optical transients. The project also involves a collaboration between universities, institutes, and industry in a bid to engage in various scientific missions that touch on the fields of astrophysics, cosmology, and gravitational wave astrophysics.
The telescopes are not only to capture these elusive transient events, but they are also expected to be sensitive to the ripples in spacetime (rarely known as gravitational waves) that may result from massive celestial events such as merging binaries of black holes or neutron stars.
The La Silla Observatory site was chosen as it has similar characteristics to its northern hemisphere counterparts such as the Low-Frequency Array (LOFAR), which the European community had built. According to BlackGEM’s lead scientist, Gijs Nelemans, the new array of BlackGEM telescopes at La Silla Observatory is expected to achieve the same level of sensitivity as the interferometric gravitational wave observatory that has been built in the US.
BlackGEM’s Place in History
The concept of BlackGEM telescopes as a gravitational wave detector array was first touted by BlackGEM founder, Paul Groot, and his colleagues. In 2017, the world saw BlackGEM’s ambition come to life with the unveiling of its first telescope poised at the La Silla Observatory in Chile. The innovative project is creating a new chapter in the rippling field of modern astrophysics.
Gijs Nelemans, the project spokesperson, explained that the BlackGEM telescopes will operate differently from the existing network of gravitational wave observatories, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and its European counterpart, the Virgo detector. While LIGO and Virgo detectors interact with the ripples in spacetime using lasers, BlackGEM will scan a significant portion of the sky and expect to see signals produced by gravitational wave events through the optical signals that emit from them.
BlackGEM’s Bright Future
BlackGEM’s telescopes are now ready for action, and the La Silla Observatory in Chile offers a unique opportunity for the project’s success. With the telescopes’ installation complete, the team at BlackGEM is now progressively combing the universe to find and study transient astronomical phenomena such as merging binary black hole and neutron star systems and supernovae events.
The BlackGEM telescope project is an innovative, groundbreaking effort that seeks to contribute to the scientific community’s knowledge and understanding of the universe. With the telescope ready to capture stunning visuals of the universe and detect ripples in spacetime, BlackGEM is one of the significant scientific endeavors of our time.

BlackGEM, an international collaboration of research institutions and universities, is on a mission to detect gravitational-wave sources using an array of three telescopes at the European Southern Observatory’s (ESO) La Silla Observatory in Chile. BlackGEM’s ambitious project aims to contribute to the scientific community’s understanding of the universe and detects ripples in spacetime that may result from massive celestial events. The BlackGEM telescopes will combine the detection of transient astronomical phenomena with the detection of ripples in spacetime to build a holistic understanding of the universe, from the macro-scale down to the micro-scale. #TECH
