Fulldome of a famous quintet
Although there are most certainly five galaxies present here in this fulldome clip of Stephan's Quintet, one member of the group is an imposter, counted among their number only by virtue of a trick of perspective. While four of the galaxies lie 300 million light-years from Earth, the paler galaxy, namely NGC 7320, is more than seven times closer, as evidenced by Hubble being able to resolve individual stars within the galaxy.
