Description

NGC 1512 is a barred spiral galaxy with a diameter of about 70,000 light-years situated in the Dorado Group of galaxies in the far southern constellation of Horologium. It is about 30 million light-years away from us.

The galaxy displays a double ring structure, with one ring around the galactic nucleus and another further out in the main disk. Both rings are visible in these pictures.

The long spiral arms of this galaxy are very dim in visible light, but they emit a great amount of ultraviolet light as shown in this image

https://en.wikipedia.org/wiki/NGC_1512#/media/File:Ngc1512_nasajpl.jpg.

The faint arms are best seen in the inverted view, labelled as the "original" image.

These faint spiral arms consist mainly of young hot stars shining brightly at ultraviolet wavelengths.

To the lower left of NGC 1512 lies the small elliptical galaxy NGC 1510. The two galaxies are currently separated by a mere 68,000 light-years. A spiral arm from NGC 1512 appears to be wrapped around the smaller galaxy, which is evidence that NGC1512 is currently being distorted by strong gravitational interactions with NGC 1510.
