We don’t see the beautiful spiral arms of galaxy NGC 5907 in this Hubble image because we are viewing it edge-on, like looking at the rim of a plate. It is for this reason that NGC 5907 is also known as the Knife Edge galaxy. via NASA https://ift.tt/2BKHZT6

Looking deep into the universe, the Hubble Space Telescope catches a passing glimpse of the numerous arm-like structures that sweep around this barred spiral galaxy, known as NGC 2608. Appearing as a slightly stretched, smaller version of our Milky Way, the peppered blue and red spiral arms are anchored together by the prominent horizontal via NASA https://ift.tt/30zSbbl
