Abstract
Although some quasistellar objects (QSOs) are known to be members of small groups of galaxies (see refs 1–3), there is no known case of a QSO in a rich cluster of galaxies4. Whether this has important implications for the nature of QSOs, or is simply a reflection of the difficulty of observing high-redshift clusters, is unclear. Here we report the discovery of a new QSO which provides perhaps the strongest evidence to date for quasar membership in a rich cluster.
