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.

Astrobites 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.

14 different outputs from a supernova model

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.

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?

Illustration of a supermassive black hole snacking on a star

Astrobites reports on a tragic final encounter between a supermassive black hole and a stellar neighbor that came a bit too close.

phases of a total solar eclipse

Take a moment to delve into three solar physics research articles with us today to learn how researchers are studying our home star.

Illustration of a dusty accretion disk surrounding the supermassive black hole at the center of a galaxy

If simulations “remember” the conditions they started with, that could complicate the modeling of magnetized accretion disks around supermassive black holes.
