As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

The collision of two neutron stars (GW170817) flung out an extraordinary fireball of material and energy that is allowing a team of astrophysicists to calculate a more precise value for the Hubble constant, the speed of the universe's expansion.

Astronomers obtained the first detailed face-on view of a gaseous disk feeding the growth of a massive baby star. They found that it shares many common features with lighter baby stars. This implies that the process of star formation is the same, regardless of the final mass of the resulting star.

Astronomers have demonstrated how a combination of gravitational-wave and radio observations, along with theoretical modeling, can turn the mergers of pairs of neutron stars into a 'cosmic ruler' capable of measuring the expansion of the Universe and resolving an outstanding question over its rate.
