The quasar SDSS J2318, pretending to be a quiet one with weak emission lines, concealed inside a furious wind accelerated to 0.3 the speed of light. This outflow is capable of sweeping the interstellar medium out of its host galaxy, forever halting star birth. The discovery, made through spectroscop

Astronomers have discovered that gas density in nebulae can't be described by a single number. Each measurement method only responds to the density range it is sensitive to. This resolves a long-standing contradiction and calls for recalculating masses and energies in star-forming regions.
