This line of galaxies is a cosmic coincidence behind the interacting system Arp-Madore 2105-332, which is a pair of galaxies 200 million mild years away within the suitably small constellation of Microscopium. Gravitational tendrils from every galaxy attain out to 1 one other, pulling stars and galaxies out and unravelling each galaxies. It’s all pretty commonplace so far as interacting galaxies go, however what’s exceptional is that line of quite a few galaxies within the background. These galaxies are utterly unrelated to Arp-Madore 2105-332 – it’s simply an opportunity alignment, however it makes for a exceptional vista. A number of the distant galaxies within the line seem purple, drained of star-forming gasoline and with solely older stars left. One is a traditional blue spiral maybe like our personal galaxy. Trying across the picture, the objects with diffraction spikes are stars in our Milky Manner. Every thing else on this picture is a galaxy, principally too faint or too distant to be resolved as something however a smudge of sunshine.
