The bigger they are, the smaller their moons?
Can bigger planets form bigger moons when whacked with bigger rocks? Maybe not!
The Recipe For Star Cluster Soup
Making a star cluster from scratch is no easy task. Today’s paper addresses the big question: what does it take to get the recipe right?
Ice, Ice, Baby!
How common are icy polar caps like ours on Earth-like exoplanets? Today’s paper explores the many versions of surface ice possible on Earth-like exoplanets, even including equatorial ice belts!
Active Galactic Nuclei have a history of causing trouble
Many astronomers believe that AGN activity is responsible for suppressing star formation. However, it appears that maybe the past behaviour of AGN is what’s really to blame.
A New Recipe for Neutron Star Magnetic Fields
How do neutron stars acquire such strong magnetic fields? Why do these fields differ between pulsars and magnetars? Today’s paper suggests that *convective dynamos* may be at play.
Perpendicular planets are less peculiar than you’d think
Simulations of planet formation around binary stars compare coplanar vs perpendicular orbits.
