IC is a spiral galaxy close to the intergalactic cloud Hanny's Voorwerp. IC is a former quasar, whose light lit up Hanny's Voorwerp, which is It is currently the nearest known quasar, being million light years away, and the one. Astronomers have found that Markarian , the nearest galaxy to Earth that hosts a quasar, is powered by two central black holes furiously. Guang Pu Xue Yu Guang Pu Fen Xi. Sep;31(9) [Galaxy/ quasar classification based on nearest neighbor method]. [Article in Chinese]. Li XR(1), Lu. These free-range planets rove around in a pair. This was the second quasar redshift measured. SUBSCRIBE RENEW DIGITAL EDITIONS GIVE A GIFT CUSTOMER SERVICE. Quasars are powered by a central black hole that heats the gas around it to unleash tremendous amounts of energy. It has been gravitationally lensed into four images, of roughly similar appearance. IC is a spiral galaxy  close to the intergalactic cloud Hanny's Voorwerp. Tonight's Sky — Enter coordinates. A nuclear ring of active star formation has been found in the center with a rate of formation greater than solar masses per year. This was the second quasar discovered with a redshift over 4.

Xavier; Cantalupo, Sebastiano; Arrigoni-Battaia, Fabrizio 15 May And many of these galaxies have encountered and merged with at least one other galaxy. This was the most distant object when discovered. Quasars are believed to be powered by accretion of material into supermassive black holes in the nuclei of distant galaxies, making these luminous versions of the general class of objects known as active galaxies.
