English: ARP 273 a pair of galaxies in Andromeda
Español: ARP 273
Un par de galaxias en interacción a 350 millones de años luz en Andromeda. La mayor es UGC 1810, su brazo exterior ha sido distorsionado por el encuentro para formar un anillo. Estos anillo son típicos en colisiones de galaxias cuando una pasa a traves de la otra. En este caso la más pequeña, UGC 1813, ha pasado a traves de la mayor. Cuando dos galaxias se encuentran la colisión afecta principalmente a las nubes de gas que forman gran parte de la materia (bariónica) de las galaxias, las distancias entre las estrellas son tan grandes que no se producen apenas choques y pasan de largo sin mayor interacción salvo que su movimiento se frena por la gravitación. Los gases sinembargo se comprimen dando lugar a ondas de choque que disparan el nacimiento de estrellas.
