Signs of Collisions to Come
Neutron star mergers produce signals across the electromagnetic spectrum. But could these binaries also flare before their dramatic collisions?

The Case of the Missing CO
Protoplanetary disks contain less carbon monoxide gas than expected. How does this happen?
Build Your Own White Dwarf Photosphere
Have you ever wanted to examine the photosphere of a white dwarf up close and personal? A team of scientists has done so — by building a piece of a white dwarf in a laboratory.
Challenging a Plasma Assumption
A recent study calls into question a fundamental assumption used to model space plasmas.
Spins Point to How Black Hole Binaries Formed
A new study uses clues from black hole spins to explore how binary black holes came to be paired together in the first place.
Searching Pulsars for Planets
A new study explores whether there are any exoplanets orbiting the well-observed NANOGrav pulsars.
A Stellar Method of Catalog Creation
Getting star catalogs out of telescope images is a tricky affair. But a recent technique promises improvements on existing catalogs, and it could be widely applicable as large-scale astronomical surveys begin.
Rescuing an Overlooked Planet
Sometimes real exoplanet detections are accidentally discarded by the automated vetting pipeline. One such error was just discovered: a habitable-zone Earth-like planet candidate.
Pulsar Discovery from an Enormous Telescope
Pulsars in distant globular clusters are a challenge to detect — but it’s a job made easier by the world’s largest filled-aperture radio telescope.
Observations of Betelgeuse’s Dimming from the Stratosphere
An airplane-borne telescope is being used to learn more about why the red supergiant Betelgeuse suddenly dimmed in recent months.
