NGC 973 group 


The NGC 973 galaxy group is a part of the Perseus-Pisces Supercluster, located in the constellation Triangulum some 200 million light years from Earth. The giant spiral galaxy NGC 973 (seen edge-on, on the right) is the largest galaxy in the group with diameter of about 230.000 light years and active nucleus (type 2 Seyfert galaxy). It is accompanied with the nearby lenticular IC 1815. The galaxies on the left (here north) side are NGC 974 (Sb spiral with opened arms) and NGC 969. You can also see another larger galaxy beneath them, NGC 978, and many smaller ones in the field.
