The Middle of our Galaxy

The Middle of our Galaxy

What does the solar system orbit?

By Sean Oh

Everybody knows that the Moon orbits the Earth and Earth orbits the Sun, but some people have other questions. They want to know what the Sun orbits. That is a good question, because in the 20th century, people wanted to know that, as new technology was made for space then. But first we must understand the concept of our own galaxies and others, too.

Our galaxy, the Milky Way, is a galaxy that looks like a cyclone-shaped hurricane, and they are right. It does look like that. The Hubble Space Telescope took amazing pictures of the galaxy from near the Earth. There are many other galaxies, too, that dazzle, sparkle, combine, throw off systems, and many other things that galaxies can do. There is also a black hole, which sucks planets, stars, galaxies, and even light itself in a typical range. Now we are ready to see what is in the middle of our galaxy.

This picture of the nearby galaxy NGC 6744 was taken with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at La Silla. The large spiral galaxy is similar to the Milky Way, making this image look like a picture postcard of our own galaxy sent from extragalactic space. The picture was created from exposures taken through four different filters that passed blue, yellow-green, red light, and the glow coming from hydrogen gas. These are shown in this picture as blue, green, orange and red, respectively.

If you guessed that a black hole was in the middle, you are correct. The black hole sucks only particles that are very close to the center. Luckily, we are in the outside of the galaxy, so we do not have to worry about being sucked in for now. Mauna Kea, the Hubble Space Telescope, (Yes, it is still in space today!) and many other satellites and telescopes helped discover this mystery.

It seems like we are the only thing out in there, but we are not… At least later we will discover more and more about our galaxy and discover even more about human life. Even more so, in space, even other solar systems seem light-years away to being discovered, but we will discover, and reopen our astronaut’s jobs.
