GREENBELT, Md., July 2 (UPI) -- NASA has released an image from the Hubble space telescope of twin galaxies astronomers say are close enough to each other to be bound together by gravity.
The two very similar galaxies, PGC 9074 and PGC 9071, are probably only just beginning to interact gravitationally, NASA said in a release Tuesday. No gravitational disturbance can yet be seen in the image, the space agency said.
