APOD 3.4


Pictured above is the barred spiral galaxy NGC 5105 and NGC 5078. They are separated by about .5 degrees, or the apparent width of the full moon. Both are found within the constellation Hydra, and are only an estimated 90 million lightyears away. They are both similar in size to our own Milky Way Galaxy. The prominent stars within the foreground lie within our own galaxy as well. I chose this photo because it is an interesting illustration of the way we perceive size and brightness to indicate distance from the Earth.
