A strange pattern
please talk about this galaxy
by Budgieye moderator
spiral galaxy, distance photoZ=0.055, so far enough away for the nucleus to be looking deep yellow, nucleus obvious,
barred spiral, two armed, and as says in recent "one arm star-forming, one arm diffuse... interacting with another galaxy? by appleseed 8 months ago" star-forming arm is very blue so is forming stars at a fast rate.
