Ice Trapped in Craters on Ceres Is Surprisingly Young
The dwarf planet Ceres hosts water ice in cold, shadowed craters. New research suggests that these ice deposits are remarkably young. aasnova.org/2024/04/24/ice… Planetary Science Institute (PSI)
The Case of Shrinking Planets
astrobites's Tori Bonidie reports on whether photoevaporation or core-powered mass loss is more likely to be responsible for the exoplanet radius gap. aasnova.org/2024/04/23/the…
Devising a Test for Special Relativity
New research explores a way to probe for cracks in special relativity with a subtle measurement of gamma-ray photons. aasnova.org/2024/04/19/dev… U.S. Naval Research Laboratory
How to Tell Space Rocks from Space Junk
One person’s space junk is another’s research opportunity: scientists study an artificial object mistaken for an asteroid to understand how to identify these objects in future surveys. aasnova.org/2024/04/17/how… UArizona Lunar and Planetary Laboratory
Ultra-Faint Dwarf Galaxies: Not as Small as We Thought?
astrobites's Brandon Pries reports on how astronomers use pulsating stars to look for stellar halos around ultra-faint dwarf galaxies, some of the smallest galaxies in the universe.
Featured Image: A Suite of Exploding Stars
A new suite of supernova simulations allows researchers to find correlations between the properties of these cosmic explosions and properties of the stars they came from. aasnova.org/2024/04/15/fea… Princeton University Research Institute for Advanced Study (IAS)
Tragic Tidal Disruption Events: How Black Holes Shred Stars
astrobites's Sonja Panjkov reports on a tragic final encounter between a supermassive black hole and a stellar neighbor that came a bit too close. aasnova.org/2024/04/09/tra…
Making Computers Count Pulses
Fitting models to pulsar arrival times is typically a tricky business. A new algorithm might let computers take on some of the decision-making burdens. aasnova.org/2024/03/29/mak… WVU Physics & Astro
A New Way of Looking at the Milky Way’s Supermassive Black Hole
The Event Horizon Telescope Collaboration has analyzed data that show our home galaxy’s central black hole in a new light — polarized light, to be precise. aasnova.org/2024/03/27/a-n… Event Horizon 'Scope
Crystallization, Convection, and a Magnetic White Dwarf Mystery
When white dwarfs begin to crystallize, can the change prompt the formation of magnetic fields millions of times stronger than Earth's? aasnova.org/2024/03/25/cry… CU Boulder News & Experts
