I Can See Clearly Now: A Deep Learning Method to Remove Clouds from Solar Images
Clouds getting in the way of ground-based solar images? A new machine learning method can identify and remove clouds, revealing the hidden solar features underneath.
Feeding CAMELS: An Exploration of Galactic Feedback Effects in Simulations
Astrobites reports on the complicated effects of black hole and stellar feedback in cosmological simulations.
Monthly Roundup: Preparing for a Potential Impact
Will the asteroid 2024 YR4 crash into Earth in 2032? Maybe, but probably not. Today’s Monthly Roundup looks at three studies that advance our understanding of asteroid redirection — just in case.
An Icy Disk in the Orion Nebula
The heart of the Orion Nebula, near the massive young stars of the Trapezium Cluster, is a dramatic place for a star to grow up. New research examines JWST images of an unusual protoplanetary disk in this exceptional setting.
Life Is Like a Box of Potential Biosignatures
Astrobites reports on how habitable exoplanets resembling Earth in its younger years might appear to the Habitable Worlds Observatory.
Featured Image: Evolution of a Supernova Ring
A ring of bright “hotspots” adorns the remnant of the supernova SN 1987A. Now, researchers have analyzed two decades of Hubble Space Telescope observations to track the evolution of this ring.
Interaction Reactions: How Galaxy Encounters Influence Star Formation
Across cosmic time, galaxies interact and merge with each other, causing disruptions in their behavior. Recent simulations explore the impacts interactions have on the star formation activity in interacting galaxies.
A New Groupie in Regulus’s Entourage?
What’s the status of the brown dwarf discovered 12.6 light-years from Regulus: group member or unrelated neighbor? New research provides clues.
Roasted Marshmallows Setting Fire to Our Understanding of Planet Formation?
Astrobites reports on how spectroscopic observations of an exoplanet can help us understand its composition and formation history.
Cracking Crusts Might Set a Neutron Star Speed Limit
Neutron stars seem to rotate at only half their maximum rate. Can the splitting of a neutron star’s crust explain why?
Testing a Recipe for a Star Within a Star
A Thorne–Żytkow object is a star with a neutron star at its core. New work examines whether these theoretical objects could be made, as proposed, in X-ray binary systems.
