Scientists have long struggled to understand how common planets form. A new supercomputer simulation shows that the missing ingredient may be magnetism.
Groundbreaking results show that neutron stars of different masses may have the same size — upending astrophysical models.
Supermassive black holes emit jets of white-hot plasma that stretch thousands of light-years across the cosmos. For the first time, researchers have identified what’s creating these jets.
Ultrahigh-energy cosmic rays twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them.
A supernova-like explosion dubbed the Camel appears to be the result of a newborn black hole eating a star from the inside out.
One black hole is nice, but astrophysicists can do a lot more science with 50 of them.
A new study shows that extreme black holes could break the famous “no-hair” theorem, and in a way that we could detect.
