NGC 1808, a warped Seyfert type galaxy in approx. 40 million light-years distance is a typical star-burst galaxy with violent star formation and jets of hydrogen and dust ejected from its active core. Around the very bright core a dim outer shell can be observed.
This peculiar shape is evidence that NGC 1808 may have had a close interaction with another nearby galaxy, NGC 1792 (outside of this image), an interaction could have hurled gas towards the nucleus of NGC 1808, triggering the exceptionally high rate of star birth.
