Video Description

Virgo Gravitational Wave Detector at the European Gravitational Observatory

Type of observatory: gravitational waves


Virgo is a Michelson laser interferometer made of two 3 km long orthogonal arms. Gravitational waves, produced by coalescences of binary systems and supernovae as far as the Virgo Cluster and beyond, can be detected in the frequency range from 10 to 6,000 Hz. Virgo is located at the European Gravitational Observatory, at Cascina, near Pisa.

Location: Italy

Latitude: +43.631346

Longitude: +10.504603

Live 24-hour webcast from astronomical observatories

Organised by: ESO, the European Southern Observatory, from its HQ in Garching, Germany

Duration: 24 hours

"Around the World in 80 Telescopes" is a unique live 24-hour webcast, following night and day around the globe to some of the most advanced observatories both on and off the planet. You can watch it right here on the 100HA website, and on the 100HA channel on

Find out what's happening at a research observatory in your country, or on the other side of the planet, and discover what astronomers are doing right now! Who is observing? What are they researching? What do they hope to discover?

You'll see a snapshot of life at many different observatories where astronomers will present exclusive images and talk about their work. Some will be observing distant galaxies, searching for extrasolar planets around other stars or studying our own Solar System. Some will be studying the Universe in visible light, others in radio waves or other wavelengths. Some may be working at solar observatories or with telescopes out in space. All of them will have a different story to tell.
