Unveiling black hole spins using polarized radio glasses

A cornerstone but surprising prediction arising from Einstein's theory of general relativity is the existence of black holes, which astronomers later found to be widespread throughout the universe. Key characteristics of ...

Paper explores ideal orbits for space-based interferometers

Ever since the telescope was invented in 1608, astronomers have striven for bigger and better telescopes. When it comes to instruments to observe the sky, bigger really is better whether you are observing faint galaxies or ...

The origins of the black hole information paradox

While physics tells us that information can neither be created nor destroyed (if information could be created or destroyed, then the entire raison d'etre of physics, that is to predict future events or identify the causes ...

JWST observes the Kuiper Belt: Sedna, Gonggong, and Quaoar

The Kuiper Belt, the vast region at the edge of our solar system populated by countless icy objects, is a treasure trove of scientific discoveries. The detection and characterization of Kuiper Belt Objects (KBOs), sometimes ...

Here's what it would take to see a black hole's photon ring

Supermassive black holes are elusive creatures. Massive gravitational beasts that can power immensely bright quasars, or can lurk quietly among the bright stars of a galactic core. We mostly study them indirectly through ...
