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.
Cosmic Rays Near and Far
How do cosmic rays move through the galaxy? Thanks to data collected by the aging Voyager 1 spacecraft, astronomers are closer to finding out.
Measuring Ages from Craters on Giant Planet Satellites
The cratered surfaces of our solar system’s moons record impacts reaching back billions of years. How do researchers measure the ages of these surfaces, and what can these ages tell us about how the moons formed?
Tragic Tidal Disruption Events: How Black Holes Shred Stars
Astrobites reports on a tragic final encounter between a supermassive black hole and a stellar neighbor that came a bit too close.

What Do Accretion Disk Models Remember?
If simulations “remember” the conditions they started with, that could complicate the modeling of magnetized accretion disks around supermassive black holes.
Evidence Says Some Blue Stars Come from Two Stars
The merger of two stars can make a blue supergiant, suggesting that many of the galaxy’s brightest stars are not born, but made.
Ghost (Particle) Hunting in Gamma-ray Bursts
Astrobites reports on a study that aims to determine whether the sources of gamma-ray bursts could also be a source of ghostly neutrinos.

A giant star-forming region in the Milky Way has a new infrared portrait, thanks to a telescope flying through the stratosphere.
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.
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.
