IC 64 is a massive lenticular galaxy located 622 million light-years away in the Pisces constellation.[1][2][3] IC 64 has a diameter of 300,000 light-years, making it, three times bigger than the Milky Way and one of the largest galaxies observed.[4] IC 64 was discovered by French astronomer Stephane Javelle on 5 December 1893.[4] It has an active galactic nucleus,[1][5] and is an emission line galaxy.[6][7]
