Large illuminous jellyfish

Myself and my husband went outside the back of our house to have a cigarette, I looked up to the sky to see the stars I noticed a bright light and thought it was an plane as we see them often, it didn't move like a plane it was stationary with red, blue, white, orange lights going from left to right along the length of it.  my husband went to get his binoculars to get a better look at the strange lights all the while it didn't move,  we both looked and were amazed to see a very large jellyfish shaped object with illuminous lights of different colours,  my husband thought he saw smaller objects going in to the largest object, but couldn't be sure,  we watched it for a good hour then went to bed
