Our Best Look at the Cosmic Web
Updated: 2025-02-04 23:35:50
At first glance the large scale structure of the Universe may seem to be a swarming mass of unconnected galaxies. Yet somehow, they are! The ‘cosmic web’ is the largest scale structure of the Universe and consists of vast networks of interconnected filamentary structures that surround empty voids. A team of astronomers have used hundreds …

Quasars are the actively feeding supermassive black holes at the hearts of galaxies and can contain millions or even billions of times the mass of the Sun. It's believed they're the source of some of the highest energy cosmic rays detected. But there are also microquasars, where a star and black hole orbit one another. Material from the star accretes around the black hole, and the magnetic fields form jets that can also hurl cosmic rays with similar energies.

Any hint of a biosignature or even a faint , technosignature-like event wrests our attention away from our tumultuous daily affairs .
