A binary black hole merger likely produced gravitational waves equal to the energy of eight suns.

Despite the planet’s seeming standstill, graduate students continue to use LIGO to identify astrophysical events.

A colliding star may have triggered the drastic transformation.

Signal from 500 million light years away is the first periodic pattern of radio bursts detected.

MIT Haystack Observatory researchers coauthor a paper announcing the observation of a surprising structure in a distant quasar, 3C 279.

Michael Calzadilla and colleagues describe a violent black hole outburst that provides new insight into galaxy cluster evolution.

With increasingly advanced data, Michael McDonald and colleagues study a galaxy cluster bursting with new stars.

Results support Einstein’s theory and the idea that black holes have no “hair.”

With help from next-generation particle accelerators, the approach may nail down the rate of oxygen production in the universe.

“We will keep listening for these faint and remote cosmic whispers,” says the physics professor.
