About image
NGC 5466 is a globular cluster inside Bootes constellation, with diameter 11' and apparent magnitude 9.2.
Its distance is 50000 light year and it is characterized by a very small concentration of stars.
Recent studies (2007) shows that this globular has tidal tails very extended (more than 45°) due to very slow dissolution caused by the effects of tides at perigalacticon and disc-crossing (more info in this interesting article https://academic.oup.com/mnras/article/380/2/749/1014346)
