 This is a unique view of a galaxy tilted edge on to our line of sight. The image highlights the galaxy structure, the subtle reddish bulge surrounding a bright nucleus, a blue disc of stars running parallel to the dust lanes, and a transparent outer halo. The dust lane is slightly warped compared to the disc of stars. This warp indicates that NGC 5866 may have undergone a gravitational tidal disturbance in the distant past by close encounter with another galaxy. We'll use this galaxy, along with several others in the Virgo supercluster, to develop our final cosmic distance ladder rung, Redshift. You may recall that we covered Redshift in our segment on planetary nabula where we used the shift in hydrogen spectral lines to determine the radial velocity of a celestial object. NGC 5866's Redshift indicates that it is moving away from us at just under 1,000 kilometers per second. That's 617 miles per second.
