Spiral Galaxy ESO 137-001 | Hubble Space Telescope
This Hubble image shows spiral galaxy ESO 137-001, framed against a bright background as it moves through the heart of galaxy cluster Abell 3627. Distance: 220 million light years
This image not only captures the galaxy and its backdrop in stunning detail, but also something more dramatic—intense blue streaks streaming outwards from the galaxy, seen shining brightly in ultraviolet light.
These streaks are in fact hot, wispy streams of gas that are being torn away from the galaxy by its surroundings as it moves through space. This violent galactic disrobing is due to a process known as ram pressure stripping—a drag force felt by an object moving through a fluid. For this reason, ESO 137-001 is also described as a "jellyfish" galaxy.
