To their surprise, they found out that this black hole contains actually 40 billion solar masses, that is 10,000 times more massive than the […]

Attempting the Impossible: Taking the First Picture of a Black Hole

ALMA joins the Global Millimeter VLBI Array (GMVA) and the Event Horizon Telescope (EHT) The Atacama Large Millimeter/submillimeter Array (ALMA) joins for the first time the Global mm-VLBI Array (GMVA) and the Event Horizon Telescope (EHT), Earth-sized virtual observatories, which are made possible by an international collaboration of radio telescopes. One of the main drivers […]

Mission impossible per l’Event Horizon Telescope

È tutto pronto per scattare la foto del secolo. Un insieme di otto osservatori simulerà un radiotelescopio delle dimensioni della Terra allo scopo di intravedere il moto del gas incandescente che circonda il buco nero supermassiccio della Via Lattea. Quali le sfide e le attese? Ne parliamo con Heino Falcke, presidente del consiglio scientifico dell’EHT, […]
