Nella piana di Cascina, vicino a Pisa è in funzione il rivelatore di onde gravitazionali VIRGO dell' INFN, un interferometro laser sensibile a deformazioni dello spazio-tempo inferiori a un miliardesimo della dimensione di un atomo. VIRGO è realizzato da una collaborazione italo-francese, il consorzio EGO.

Gravity may seem elementary. But proving Einstein's theories about it is quite hard. To do so, scientists are struggling to capture gravity's most elusive hallmark: the gravitational wave. This Astro Feature focuses on research at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Livingston, LA, where scientists have constructed a sprawling facility dedicated to the detection of minute changes in spacetime caused by gravitational waves traveling from energetic events in space.

Distant Quasars: Shedding Light on Black Holes

# data[].attributes.attachment_link.description
How can scientists study a faraway black hole that emits no light? By observing its quasar. As objects get pulled onto the accretion disk orbiting a supermassive black hole, friction creates a bright light known as a quasar. In this video, researchers use a "galaxy-sized lens" to analyze light from a distant quasar-revealing a supermassive black hole with a truly voracious appetite.

The Laser Interferometer Gravitational-Wave Observatory (LIGO) consists of two widely separated installations within the United States - one in Hanford Washington and the other in Livingston, Louisiana - operated in unison as a single observatory. LIGO is operated by the LIGO Laboratory, a consortium of the California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT).
