I’ve Got Some Oceanfront Property… Around a White Dwarf
Astrobites reports on whether planets around Sun-like stars destined to become white dwarfs are able to hold on to their oceans.

Featured Image: Details of a Rare Ejecta Nebula
New images highlight the clumpy ejecta and radial streaks surrounding WR 8, a Wolf–Rayet star that may be changing from one spectral subclass to another.
Crater Cartography: Mapping the Moon’s North Pole
New high-resolution maps of the Moon’s north pole reveal interesting terrain and locations possibly preserving water ice, which will inform future lunar exploration.
Black Holes Grow Better with a Friend
Astrobites reports on observations of dwarf galaxies that show how a buddy galaxy can help trigger phases of rapid black hole growth.
Research Notes of the AAS Celebrates Its 2,000th Publication
Since 2017, the Research Notes of the American Astronomical Society (RNAAS) has provided a venue for brief research reports, student work, null results, and more. Editor Chris Lintott shares his reflections on a recent RNAAS milestone: 2,000 Notes.
Two More Double-Faced White Dwarfs Discovered
A search for white dwarfs that present different compositional “faces” as they spin has dredged up two new members of the emerging class of double-faced white dwarfs.
A Slowly Spinning Pulsar Below the Death Line
A serendipitous discovery illuminates the kinds of objects that might bridge the gap between pulsars and long-period radio transients.
Mapping Eruptions on Enceladus
Saturn’s tiny moon Enceladus was the first moon in the solar system known to spout plumes of water ice and vapor. A new study investigates the behavior of these plumes and the network of fissures from which they emerge.
Shedding Light on Candles That Burn a Bit Too Bright
Astrobites reports on how standard candles might not be quite as standard as previously thought, and how a particular type of supernova is making a name for itself.
Featured Image: Lunar Swirls
Researchers investigate the cause of bright, sinuous swirls that are associated with magnetic fields embedded within the Moon’s surface.
Spinning Up: Impacts of Stellar Collisions on Binary Black Hole Mergers
How do interactions binary black holes experience in dense star clusters impact the gravitational waves we detect on Earth? Recent simulations show that stellar collisions leave imprints on the masses and spins of these black holes.
Rapid Microlensing Classification: A Lonely SOBH Story
Astrobites reports on how we can use simulations of stellar populations to rapidly estimate the identity of the lensing object in a microlensing event.
