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.
Astronomy Impacts of Satellite Megaconstellations
A recent study explores how SpaceX’s Starlink satellites and other megaconstellations will impact astronomical observations in the future.
Merger Partners? Maybe.
Could the participants in binary black hole mergers be picky about who they merge with?
Jets from a Galaxy Collision
New observations confirm a long-theorized link between galaxy mergers and the launch of powerful relativistic jets.
Peering Into the Atmosphere of the Hottest Planet Known
What’s going on inside the atmosphere of KELT-9b, the hottest exoplanet known? New observations give us a look.
