Hubble Telescope shows ARP 86: interacting strange galaxies

this smaller companion galaxy almost seems to be attached to NGC 7753. It is this particularity that won the title of “ARP 86” – marking that the pair of galaxies appeared in the atlas of pecuriar galaxies compiled by astronomer Halton ARP in 1966. The gravitational dispute between the two galaxies is doomed to a disastrous outcome for NGC 7752. It was eventually either thrown out of intergalactic space or completely swallowed up by its much larger neighbors

Hubble’s observation of ARP 86 is part of a larger effort to understand the link between young stars and the cold gas clouds they form. Hubble stares at star clusters and gas and dust clouds, which are distributed in various environments of nearby galaxies. Combined with measurements from Alma, a huge radio telescope is located high in the Andes of Chile. These Hubble observations provide a data repository for astronomers committed to understanding how stars are born

these observations also sow the seeds for the future research of the upcoming Space Telescope NASA / ESA James Webb Space Telescope. The telescope, which will be launched later this year, will study star formation in dusty areas, such as ARP 86 galaxy
