"We don't know if this object is the heaviest known neutron star, or the lightest known black hole, but either way it breaks a record."

Laser labs pick up a signal emanating from the collision of two dense, dead stars.

Ever since the detection of gravitational waves, researchers have been searching for the bursts of light that may accompany the collisions that cause them.

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

After a hiatus, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is back and better than ever, ready to hunt down ripples in space-time.

Knowing how fast the universe is expanding could tell us a lot about its age and size, and soon, we may learn a lot more about the exact measurement.

Simulations of merging galaxies are giving researchers insight into how supermassive black holes get so gigantic.
