isolated barred spiral galaxy exhibiting a very geometrical double ring structure that resembles a
Dreamcatcher. It is located 65 million light years from the Earth, in the constellation of Fornax.
The galaxy, with a diameter of 135,000 light years, is slightly larger than the Milky Way and has
over 100 billion stars.
