Quasars with low-energy X-ray emission, and thus a lower temperature in the corona, show faster winds. This indicates a highly rapid growth phase that exceeds a physical limit for the accretion of ...
This quasar is 500 trillion times brighter than ... 0.06 microseconds to each day’: How Chinese dams are slowing Earth’s spin ‘$250 million’: Boeing faces additional losses on Starliner ...
The quasar's distance is described by a property called its redshift - a measurement of how much the wavelength of its light is stretched by the expansion of the Universe before reaching Earth.
The James Webb Space Telescope (JWST) captured a stunning image of a distant quasar, RX J1131-1231, through gravitational lensing. This phenomenon, caused by a nearby elliptical galaxy ...
