NGC 3718 - 21.3.2015 at 20.33 - 22.3.2015 at 02.26 Hyvinkää Observation number 36848

Visibility III / V

Timo Inkinen, Ursa (Etelä-Suomi)

The picture shows an interesting area from the constellation of the Big Bear. The brightest galaxy in this field is NGC 3718 and the adjacent NGC 3729 are interacting galaxies. The gravitational effects of these two shape the shapes of galaxies out of the ordinary. Above this pair is a similar cluster of five galaxies called Hickson 56. Also in this distant group, galaxies interact with each other.
