Photographier, c’est dire et éprouver le plaisir d’être en vie, et de transmettre ce désir à son tour, pour celui qui regarde les photos.

This galaxy is a member of a small group of galaxies that includes M65 and NGC 3628, known as the Leo Triplet, or the M66 Group.

The ring nebula is a little jevel.
For more explanation please read this : en.wikipedia.org/wiki/Ring_Nebula
Extract of wikipedia :
"Such objects are formed when a shell of ionized gas is expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf"
On the zoomed photo, you can see the white dwarf in the center of the nebula.

Merry Christmas to all my friends on here. Our 8 year old was quite restrained this year and held off until 5:55 to drag the rest of us out of bed. Plenty of Christmas magic here, I hope it finds you as well.
As for this year's "card". A nice memory from 25 years ago. A pair of loaner SD9s had spent the holiday in L'Anse. On the 26th a crew arrived to put the outbound train together. The sun was shining in L'Anse but as is often the case up here at the top of the hill clouds and snow prevailed. Plenty of fresh snow covered the tracks since the train came in a couple days prior, not a problem for these sure-footed veterans of the iron ranges across the big lake.
