At first glance you may think of this image as a digital rendering or perhaps a rip in spacetime; light from another universe flooding into the fold, alerting the rest of this universe to its presence. The reality isn’t quite that dramatic but awe inspiring nonetheless as this galaxy, NGC 5866 is being viewed edge-on from our vantage point in the Milky Way. As we look back in time 45 million light years ago we can see some interesting things about this star city. First, the incredible clarity in those dust lanes delivered to us via the Hubble Space Telescope, spans a large portion of the 60,000 light year diameter plane. The nucleus, like that of our own Milky Way, glows brightly from behind the shroud that the material created by those dust lanes. In addition, we also see the telltale sight of younger blue stars along the plane indicating that star formation is alive and well while the nucleus is filled will yellow ancient stars.
