NGC 5679 also known as Arp 274, is a triplet of galaxies, spanning about 200 000 light-years and at some 400 million light-years from Earth in the constellation Virgo.
This image was produced by Hubble's Wide Field and Planetary Camera 2, and is a blend of blue, visible, infrared and hydrogen emissions. The central bulges house older, yellowish stars and a bright central cluster of stars.
The left and right galaxies are prolific star nurseries, shown by the bright blue centres of star formation - the young blue stars and pinkish nebulae clearly map out the spiral arms. Interstellar dust is visible in silhouette against the bright background. The two bright stars immediately above the galaxy on the right are in our own galaxy.
The name "Arp 274" derives from being included in an Atlas of Peculiar Galaxies drawn up by Halton Arp in the years from 1962 through 1967. Arp was a vocal opponent of the use of redshift to determine galactic distances.
The redshifts of the three components of this system are: left 7483kps, central 8654kps and right 7618kps. By conventional interpretation left and right are of the same order of distance, with the centre component substantially further (17 - 23 Mpc), whereas it is apparent that the left and centre components are interacting gravitationally. A similar situation holds in Stephan's Quintet.
