NGC 672 - IC 1727

NGC 672 (a sinistra) e IC 1727 (a destra) sono due galassie interagenti nella costellazione del Triangolo: l’interazione è visibile nella banda radio dell’idrogeno neutro dove si osserva una coda mareale di materia tra le due galassie.
NGC 672 ha una massa più grande di IC1727 e questo spiega la maggiore distorsione osservabile otticamente in quest’ultima galassia.
NGC 672 dista 26.1 milioni di anni luce e la sua distanza da IC1727 è di solo 85000 anni luce.

----------

NGC 672 (on the left) and IC 1727 (on the right) are two interacting galaxies in Triangulum constellation: the interaction is visible in the neutral hydrogen radio band where a tidal bridge is observed between the galaxies.
NGC 672 appears to be the more massive of the two, and hence IC 1727 shows more distortion from the interaction. NGC 672 is 26.1 million light years away and its distance from IC 1727 is only 85000 light years.
