I’ve been looking for a picture of the constellation Sagittarius since it is located in the sky at the place where the Milky Way Center is. Once you know what Sagittarius looks like, you can find it in the sky. When you’re looking at Sagittarius, you’re looking at the Galactic Center of the Milky Way.
Sagittarius is one of the cutest constellations because it can be identified by a grouping of stars that look like a teapot.
In this nighttime photograph of the the Hale 200-inch Telescope at Palomar Observatory, northeast of San Diego, California, you can see “the teapot” above and to the right of the domed telescope.
Just “join the dots” of the stars and you’ll see that they make a teapot. It is tilted upward and to the left. The “spout” is facing the left. The “handle” is on the right. The “teapot lid” looks like a triangle.

Here’s a great site on Black Holes.
Since we’ve been talking so much about the Black Hole at the Galactic Center, I thought you’d like to read up a bit on Black Holes.
This is a Hubble Space Telescope site. It has an animated Journey to a Black Hole and a Black Hole Encyclopedia.

While waiting for clouds to clear during a night of sky observing during this year’s Winter Star Party in the Florida Keys, we got into a discussion about the Milky Way’s galactic center.
Here on earth, we live in a part of the Milky Way which is not very dense with stars. We’re near the end of one of our galaxy’s spiral arms in an area of few stars and a lot of stellar dust. Therefore, our skies look mainly dark with pin-pricks of stars.
However, if we lived on a planet in the center of the Milky Way galaxy, where it is crowded with stars, our night skies would be as brilliant as our day skies.
Here’s a link to a picture of the many stars in the Milky Way Center.

Another amazing photo of the Center of the Milky Way.
This photo shows the location of the Black Hole at our galaxy’s center.
The previous post showed a close up of the Black Hole location.
This photo shows a longer view of the Black Hole location in the Milky Way’s Center.
A very dynamic picture!!!

OK, in an earlier post I said that the Black Hole at the Center of the Milky Way galaxy is just a theory, according to some astronomers.
Well, it isn’t a theory to some other astronomers. They’ve taken a picture of it. OK, you can’t really take a picture of a Black Hole since even light is swallowed by its intense gravity. That’s why it’s called a “Black” Hole.
They can only take a picture of the area the Black Hole is in. Here’s a picture of the center of the Milky Way. The arrow shows the location of the Black Hole.
The photo was taken at the La Silla Paranal Observatory in the Atacama desert in Chile, which is in South America.
This is an amazing picture!!!

Scientists are looking at the star-crowded center of our home galaxy, the Milky Way, for likely star candidates with circling planets.
Here’s an amazing Hubble space photo of our galactic center with stars that scientists believe may have planets.

Here’s another fantastic photograph of the center of our galaxy, the Milky Way.
These are nebulae that are located in the same area of the sky where the constellation Sagittarius resides.

Here’s a link to a dynamic photo of the center of our galaxy, the Milky Way.
Some believe the earth will exactly align with the galactic center on December 21, 2012, an important date in the ancient Maya’s Long Count Calendar signifying the beginning of their next 5,000 year millennium.

Here’s a link to a fantastic photograph of the Milky Way.
Sagittarius and the center of the Milky Way is about one third of the way up from the bottom of the photo.
Some people believe that the December 21, 2012 prediction has to do with the earth’s alignment with the center of the Milky Way.
This is a gorgeous photo. The Milky Way is very difficult to see except on dark moonless nights and only after your eyes have become accustomed to the darkness.
It is even more difficult to photograph because you need a very long exposure since the Milky Way is so faint. Because the earth keeps rotating during the exposure, the camera has to be on a sky tracking device that turns at a rate in sync with the apparent movement with the sky (it’s the earth that’s really moving). Here’s the photo:
