Fun fact: The Moon turns red during an eclipse because of how the Sun's light interacts with Earth's atmosphere. As it hits the atmosphere, shorter wavelengths of light such as the color blue are scattered outwards. Longer wavelengths like red, however, are bent or refracted into Earth's umbra.
When you are out on a clear night, look up and wave; something might be photographing you! What? Read on and find out why. Today's image is not my best image, but it's one of my favorites. This is the NGC 70 Group of galaxies. I love taking pictures of galaxies; the thought of billions of stars in any one galaxy, with each one of those stars most likely having solar systems like ours, blows my mind. This image, comprising only about five hours' worth of data, shows well over 50 galaxies.

Context: I have a theory, and i want to see if im right. for simplicity, its just the big three + the 'other' option. Apologies for no vanilla extract, i want actual data this time lol.
Galaxies can merge, collide, or brush past one another — each of which has a significant impact on their shapes and structures. As common as these interactions are thought to be in the Universe, it is rare to capture an image of two galaxies interacting in such a visibly dynamic way. This image, from the NASA/ESA Hubble Space Telescope, feels incredibly three-dimensional for a piece of deep-space imagery.
The subject of this image is named Arp 282, an interacting galaxy pair that is composed of the Seyfert galaxy NGC 169 (bottom) and the galaxy IC 1559 (top).
