Arp 92
The most spectacular anomalous galaxy association was just found by 2 Spanish astronomers at the Canary islands.
Under the name Arp 92, NGC7603 and NGC7303B, with redshifts of 0,029 and 0,057, they are apparently linked by a bridge of matter, even though they must be very far apart.
2 new objects were found with redshifts of 0,243 and 0,291, inside the filament.
How can we explain the association of 4 galaxies which are apparently very far away from each other, according to their redshift?
