Description

Barely visible in this image (because of a relatively short exposure), there are actually two just recently (in 2015) discovered tidal streams around Whale galaxy. Here is some more decent photos and a nice small article about them (plus there is a link to a whole scientific paper on that page).

I tried to show these streams in Rev B in negative.
