Fade between Hubble and Chandra images of ESO 137-001

This image begins with a Hubble-only view of spiral galaxy ESO 137-001. It then fades to show the image with Chandra observations overlaid.

This second image combines NASA/ESA Hubble Space Telescope observations with data from the Chandra X-ray Observatory. As well as the electric blue ram pressure stripping streaks seen emanating from ESO 137-001, a giant gas stream can be seen extending towards the bottom of the frame, only visible in the X-ray part of the spectrum.
