NGC 3314 is formed by the spiral galaxy NGC 3314A and the also spiral galaxy NGC 3314B. Of course, do not think they are interacting . It is the magic of perspective , because "the two galaxies, located between 117 and 140 million light years apart in the constellation Hydra, are not actually physically related and only seem to overlap when viewed from Earth," explains Enrichetta. Iodice of the Istituto Nazionale di Astrofisica.
"This unique alignment gives astronomers the opportunity to measure many properties of galaxies, such as how dust absorbs light from stars, and thus better understand their composition and evolution."
“This image was taken as part of the VST Early-type Galaxy Survey (VEGAS), which aims to investigate very faint structures in galaxy clusters. Our study suggests that UDG 32 may have formed from filaments derived from NGC 3314A, but more observations are needed to confirm this, ”the astronomers explained.
