M51: Cosmic Whirlpool
Credit & Copyright: Tony and Daphne Hallas
Explanation: Follow the handle of the Big Dipper away from the dipper's bowl, until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you'll likely find this stunning pair of interacting galaxies, the 51st entry in Charles Messier's famous catalog. Perhaps the original spiral nebula, the large galaxy with well defined spiral structure is also cataloged as NGC 5194. Its spiral arms and dust lanes clearly sweep in front of its companion galaxy (left), NGC 5195. The pair are about 37 million light-years distant and officially lie within the boundaries of the small constellation Canes Venatici. While M51 is visible as a faint, fuzzy patch in binoculars, this sharp color picture was made with a 14 inch telescope and combines digital camera exposures totaling 3 hours and 42 minutes.

To say say that incredible picture leaves me speechless in an understatement.
Reminds me of my favorite cephalopod, the Chambered Nautilus. Nature's wonders ... ahhhhhhhh. &;-)

This is a nice way to start the morning! Good Work.
Some would say I am easily amazed but I would have guessed Hubble and not a couple in their backyard had photographed this. For those who have not already done it, I suggest going to Tony and Daphne Hallas' Gallery link.

I read a book years ago which dealt with Fibonacci numbers and patterns in nature. I don't remember if his equations apply to the pattern in galaxies, in particular spiral galaxies?
