Arecibo Observatory data help lead to discovery of cosmic ‘heartbeat’

An international team of researchers using data from Arecibo Observatory and the Fermi Space Telescope have discovered what they call a “gamma-ray heartbeat” coming from a cosmic gas cloud. The cloud is in the constellation Aquilla and “beats” in rhythm with a black hole 100 light years away in a microquasar system known as SS 433. The results were published today in the journal Nature Astronomy.
