Summary[edit]
| Description |
This mess of a diffuse single-armed barred dwarf spiral galaxy may not have the symmetry one tends to gravitate towards. However, it's certainly full of character. This galaxy may be in the same category as the Large Magellanic Cloud, but much more defined. This galaxy may seem very different given its Arp designation, but its morphology isn't that unique. This galaxy is interacting with its similar neighbour NGC 4625. The two are connected by a stream of hydrogen gas, but few stars lie in the stream, so it is incredibly faint. In true colour, those green puffs of gas would appear pinkish red. Maybe someone will feel inclined to look at this galaxy with narrowband imagery one day. One of the channels had a chip gap, which you may be able to spot running diagonally down the centre of the galaxy as an area of cyan and red stars. I removed a lot of tiny cosmic rays. Data is missing in the corners for the blue channel, so the colour there is a much smaller range. At the moment I'm pretty much just going through the Arp catalogue, which is full of interesting galaxies, and seeing if Hubble's taken a look at them. I am eternally grateful that all of this scientific data is publicly available and I fear that I'm taking it for granted. A day may come when that is no longer the case. I think it's pretty incredible that we have so much data available to us. Thank you!
