Magnetars are ultra-magnetic neutron stars, cosmic beasts that emit bursts of radiation so powerful they can shake entire galaxies. Learn how they form, what makes them unique, and why their mystery continues to fascinate astronomers.

If you could stare into the heart of a galaxy, past the light, past the stars, and into pure darkness, what would you actually see? When astronomers talk about the black hole shadow, they’re referring to one of the most mind-bending sights in the universe, the silhouette of the unseeable, the faint outline of where […]

If we were to rank the theories that have changed human history forever, the General Theory of Relativity would be at the top. The results it reveals are beyond human understanding. They show that the cosmos is filled with perplexing phenomena, some of which are purely hypothetical yet mathematically elegant. One such phenomenon is the […]
