Very interesting paper by @govertschilling for Sky and Telescope, on the discovery of the Big Ring by @morninglopez et al., with quotes from Jim Peebles (“I am hoping for anomalies that could prove to be empirical hints to a better theory”), Carlos Frenk, and Rien van de Weijgaert.

Photo: #Hubble's lens reveals ancient quasar 3C 273, shining from a distant #Galaxy in #Virgo constellation. After 2.5 billion years, its light finally reaches us, making it one of our closest quasars. Discovered by astronomer Allan Sandage in the '60s, it remains a celestial marvel.

#SpaceFactSunday: Did you know that quasars can outshine an entire galaxy? 🤔✨🌌

These luminous beasts unleash energy from supermassive black holes at their cores, making them the ultimate cosmic light show. It's like a celestial fireworks display on steroids!
