Così nasce una nuova astronomia multimessenger

US researchers say they have detected gravitational waves, which physicist Albert Einstein first described 100 years ago as 'ripples in the fabric of space-time.' Scientists from Caltech and the Massachusetts Institute of Technology (MIT) made the announcement in Washington and other locations around the world. There were immediate suggestions that the discovery could well win them the Nobel Prize in Physics. The signal detected with LIGO, an observatory with sites on both sides of the United States, was very clear and there was no room for doubt that it was direct evidence of the waves, said Bruce Allen, who is acting director at Germany's Max Planck Institute for Gravitational Physics.

Non ancora smaltita la sbornia dopo l’assegnazione del Nobel ai suoi padri fondatori, LIGO insieme al suo partner italiano Virgo, fa di nuovo notizia con una rilevazione anche questa storica che coinvolge una sorgente diversa da quelle finora osservate, limitate alla fusione di buchi neri, ovvero le stelle di neutroni.
