Hubble’s View of the Polar Ring of Arp 230: NASA Image of the Day

By Last Updated: February 10, 2015Views: 2517

Here we have a clear and distinct image of the Star Child on his way from Europa. No, that’s silly. It’s really the cosmic cocoon of Adam Warlock obviously. Anyone can see that.

In reality it is Arp 230 a galaxy of strange shape and part of the “Atlas of Peculiar Galaxies” produced by Halton Arp. Which is a real thing.

Now who’s going to be the first person to write a comic book based on the Atlas of Peculiar Galaxies? The main character can be Lord Halton of the Polar Ring of Arp. Make it so.

All kidding aside this is a gorgeous image. The galaxy continues to amaze.

This image shows Arp 230, also known as IC 51, observed by the NASA/ESA Hubble Space Telescope.

Arp 230 is a galaxy of an uncommon or peculiar shape, and is therefore part of the Atlas of Peculiar Galaxies produced by Halton Arp. Its irregular shape is thought to be the result of a violent collision with another galaxy sometime in the past. The collision could also be held responsible for the formation of the galaxy’s polar ring.

The outer ring surrounding the galaxy consists of gas and stars and rotates over the poles of the galaxy. It is thought that the orbit of the smaller of the two galaxies that created Arp 230 was perpendicular to the disk of the second, larger galaxy when they collided. In the process of merging the smaller galaxy would have been ripped apart and may have formed the polar ring structure astronomers can observe today.

Arp 230 is quite small for a lenticular galaxy, so the two original galaxies forming it must both have been smaller than the Milky Way. A lenticular galaxy is a galaxy with a prominent central bulge and a disk, but no clear spiral arms. They are classified as intermediate between an elliptical galaxy and a spiral galaxy.
