Finding Structure Among Black Holes

New research has explored the populations of black holes involved in catastrophic, gravitational-wave-emitting collisions — and an interesting pattern has emerged.

Going with the Outflow

Astrobites reports on the closest look yet at the mysterious outflows from high-mass newborn stars.

A Pileup of Perpendicular Planets

A new study explores what we can learn from planets that are misaligned with their stars.

Astrobites reports on how cosmic rays can knock molecules from the ice layers on dust grains into gas, a process known as desorption.

Illustration of a pulsar and disrupted star in a binary

The largest filled-aperture radio telescope in the world has discovered a new assortment of distant, pulsating neutron stars.

In the simulated cross-section of a protoplanetary disk shown here, dust swirls around as a consequence of the recent passage of an orbiting planet.


Science with a Single Merger Event

Future gravitational-wave observatories could enable us to use a single binary neutron star merger to measure the universe’s rate of expansion.
