nice zoom in vid.

Spiral shows a nice dense disc of older stars and a few outer blue spiral arms with very few intervening stars. The galaxy appears to be practically symmetrical.

Appears to have had a dual stage history with the current being a reactivation outside of the old disc as a result of the slow accretion of more gas.

The lopsided spiral effect in the bright disc may be a dust dimming effect from dust in the disc before meeting a density wave.

Have a nice day: Ag
