Hello, I am Professor and this is my report on my observation and research of the Andromeda Galaxy. I observed the Andromeda Galaxy on February 29th from Redwood City with a meet star navigator telescope. The telescope had an aperture of 130mm and I used a 25mm eyepiece. Through this telescope the object looked like a very faint elongated band of light and I had to use my peripheral vision to see it. If we compare this to professional pictures the galaxy looks elongated because it is a near edge on spiral galaxy. It is fuzzy because it is so far away that small telescopes cannot resolve it to individual stars nor can we normally see the details of the spiral structure and dust lanes. The Andromeda Galaxy is a large galaxy that may be up to 1 trillion stars. It is the closest major galaxy to our own at a distance of 2.5 million light years. Despite it having more stars it is so to be less massive than our Milky Way galaxy, the difference being due to greater dark matter content in our galaxy. The two galaxies are on a collision course with the merger starting in about 4 billion years. The Andromeda Galaxy is significant in the history of astronomy as it was key in the great debate of the 1920s. It was subsequently that another astronomer had been Hubble accurately measured the distance to Andromeda using C-Feed variable stars and hence revealed the enormity of distances between galaxies and the scale of our universe. The spiral galaxies are some of the most common type in the universe. They are characterized by having a flat disc-like shape with a central bulge that is distinctly yellowish in color with surrounding spiral arms dominated by bright blue giant stars and thus to form new stars. Some of these galaxies even have an elongated ball like bulge. Our own Milky Way is thought to be a bar spiral galaxy as well. Thank you.
