Charles Messier was an astronomer active in the late 1700’s. His interest was comets, and he would sit in his roof-top in Paris and search the heavens at night. Of, course, light pollution was not a thing in Paris at that time. The best telescopes of the time were about as powerful as the beginner scopes are today. Thus, to Messier, the objects we now to know as galaxies, star clusters and nebulae appeared only as fuzzy patches of light. Just like the comets he was searching for. So to avoid confusion on whether he was finding a new comet, or simply finding one of these non-comet objects, he created a catalog of the objects he did not want to find again. Other astronomers of the time helped him and the list grew to 100 objects. Later 10 more objects were added, and the list now stands at 110 objects. The Messier Objects catalog is very popular with backyard astronomers because many of the objects in it are fairly bright making them easy to locate for the amateur. It’s kind of funny to think that this list of unwanted objects, is now the # 1 list for amateur astronomers. I expect to be conspiring all of these in about 6 months. Some are not visible for a while.

The Messier catalog is a popular list of astronomy targets for backyard astronomers, and I’m working my way through it. I have about 50 so far out of 110. I will be periodically updating this post as I add more images.

This is a type of rock called a banded iron formation.

It's made of alternating layers of iron oxides (magnetite and haematite) and silica (chert and chalcedony).

It's 3.2 billion years old.

And it formed before life had oxygenated Earth's seas and atmosphere. It's almost from another planet.

A map of the night sky showing the positions of Mars, Jupiter, Uranus, Neptune, Venus and Saturn, spanning the sky from East to West. From https://stellarium-web.org

#PlanetaryParade excitement is fantastic! #DoLookUp But I'm baffled by the media saying 25th Jan is a "once in a lifetime event" 🔭🧪
The awesome foursome Mars, Jupiter, Venus & Saturn have been on display for weeks + Neptune & Uranus if you have a telescope. We won't see Mercury until late Feb🤔
