Wondering about Other Moons.

Yesterday, I talked about our moon's libration.  One of my readers, Gypsy of the "On The Road Again" blog, asked about the dark side of the moon and that she had never seen a picture of it.  Of course, up until the space age, no one from Earth had ever seen the other side of the moon.  To satisfy her curiosity, I sent her this picture of the far side of the moon:


 
Looks a little different.  Has a lot more impact creators, which makes sense, since the side we see is protected by Earth.
 
There are lots of moons out there in the universe and many here in our own solar system.  As far as we know, only the two inner most planets, Mercury and Venus, don't have any moons.  Just in case anyone out in blog land is interested, here is a list of all the moons in our solar system:
 
As you all know, you can click on any inserted picture to enlarge it.
 
OK, let's change the subject.  An update to what birds have come to my new bird feeders.  Yesterday, a Blue Jay found the feeder, but he didn't stay very long and hasn't been back, that I know of.  Picked up a couple more bags of wild bird feed.  After watching what goes on out at the bird feeder, don't any of you ever take it as a compliment when someone says that you "eat like a bird"!!  Now, you all have a great day today, you hear?

  1. I appreciate you posting the 2nd picture of all the moons in our solar system. Now I wonder why we only have one moon. And this is the first I've ever heard of Asteroid Ida. DD, you are a walking encyclopedia!

    1. Gypsy, astronomy is one of my favorite hobbies. I have a few telescopes from one with a three inch mirror up to one with a sixteen inch mirror. That big mirror three inches think and weights almost a hundred pounds just by itself. I take the scope apart into three pieces so I can handle it. When set up, it is taller than I am, but you sure can see some great things.

  2. I don't remember seeing a picture of the back side of the moon, I must have, I just don't recall it. There are a lot craters....

    1. Not too many people have or, if they did, didn't take notice. The astronauts who went to the moon saw it and the life on Mars saw it (grin).

  3. Don't know what kinds of birds are in your area, but black oiler sunflower seeds are a favorite with cardinals and other seed eaters that have heavy beaks. I'm surprised that blue jay didn't squawk the news of your feeder to all his buddies....

    1. That Blue Jay was back out there just a few minutes ago and he (or she) was alone, so far. As far as the seed goes, I don't want to spoil them. They all seem to be piggish about the mixture I am giving them now.

    1. Birds eat worms, cats eat birds, dogs eat cats, coyotes eat dogs, . . . dang, it is a dog eat dog world out there, even in nature. Yep, some birds are down right mean, for sure.

  5. I''ll see you on the dark side of the moon. I'm fascinated by the moons within our solar system. I think Triton, orbiting Neptune, is intriguing.

    Take good care, sir.

    1. Yes, among other things it is the coldest object in our solar system and it's density is high. Must have a lot of rocks. It also orbits Neptune in the opposite direction that Neptune is spinning.
