Quarks' galaxy

From Tardis Wiki, the free Doctor Who reference
The Quark home planet transmits signals to Earth from its galaxy. (COMIC: Martha the Mechanical Housemaid)

The Quark home planet was in a galaxy which was distant from Earth. (COMIC: Invasion of the Quarks, The Killer Wasps, Martha the Mechanical Housemaid)

Other planets in the galaxy included Gano (COMIC: The Killer Wasps) and a jungle planet. (COMIC: Jungle of Doom)

According to the Fourth Doctor, the Quarks inhabited a completely different era and region of the universe to the Krotons. Thus, to witness a conflict between the two races would not "make sense". (COMIC: The Lost Dimension)
