Quasar
3 reportsQuasar is an astronomical object studied through its light, motion, composition, environment, and population context. Evidence comes from mass estimate, chemical abundance, and object classification, and competing models remain viable when observations are sparse or indirect.
Scientific coverage devoted to Quasar addresses environmental interactions, while also considering population context and mass estimate. One line of support comes from distance or orbit estimates, and a separate test comes from model comparison; together they clarify population context, but the result is bounded by the possibility that limited viewing geometry and indirect measurements can leave competing explanations.

Webb Telescope Spots Candidate Black Hole Star in Early Universe
Astronomers using the James Webb Space Telescope have identified a luminous, solar-system-sized object from 660 million years after the Big Bang, offering the strongest evidence yet for a hypothesized 'black hole star' class.
Black Hole Winds Drive Turbulence Far Beyond Host Galaxy
Observations with Japan's XRISM X-ray satellite reveal that outflows from a supermassive black hole in a distant quasar are far more powerful than previously estimated, stirring hot gas across intergalactic space
Chandra X-ray Observatory reveals hot gas from early quasar
NASA's Chandra X-ray Observatory has detected extremely hot gas surrounding a distant, radio-quiet quasar, offering new insight into the formation of galactic cluster atmospheres in the early universe
