Hubble Space Telescope Image
Q 1) I can discover four stars from the Hubble space Telescope.
Q2) Determining the range of galaxies found in the image.
The image was quite small to enable me count number the number of galaxies, therefore I magnified it to have a clear view of the objects in the image. From the magnified image, I divided it into 4 quarters and from the bottom left quarter I was in a position to count around 372 galaxies. To get the complete galaxies in the whole image I increased 372 by four to get a whole number of 1,488 galaxies from the image.
Q3) I noted Blue as the most common color in the image. I arrived at this conclusion through subdividing the image into four quarters and counted the galaxies in the bottom left quarter. The blue galaxies had the highest number of 306 and appeared to be the furthest. The orange-red galaxies were 42 in number and appeared to be bigger than blue and white. The white galaxies had the lowest number of 24 from that quarter. These white galaxies were relatively bigger than the blue ones but smaller than the orange-red galaxies.

Q4) Assuming that the all galaxies in this image have same diameter.

Most galaxies (a total of 306 blue objects in the bottom left quarter) in this image are relatively far because they appear smaller. From my analysis on the bottom quarter of the image there were 306 blue galaxies which were very small compared to 42 orange-red galaxies which were relatively bigger in size and only 24 galaxies were of medium size.

Phase II – Does the Evidence Match a Given Conclusion?

Q5) Images of five closet galaxies found on the image using the magnifying glass.

On the generalization that nearby galaxies are equally split between circular round and elongated spiral shapes. I would differ with this concept, because although most of the galaxy images are round round and extended curved shapes there are some that are triangular shaped and others are quite irregular. .For instance the blue galaxy that I have indicated in my above diagram is not circular but more of a triangle.

Phase III – What Conclusions Can You Draw From This Evidence?

6) Evidence based conclusion.

The general distribution of the galaxies from the first green sample in the above graph, indicates that the blue white galaxies are more than the red orange galaxies. This trend goes on until the fifth green circle sample. It is therefore evident that the blue-white galaxies are more in number from any single green sample taken in the image, this is because they are smaller in size than the red-orange galaxies which are fewer in each sample and bigger in size.

The further the galaxy from the earth, the small they appear and the more they are in number, the closer a galaxy is to the earth the bigger it is in size and they tend to be few.

Phase IV – What Evidence Do You Need To Pursue?

Are there more nearby galaxies or extremely distant galaxies?

Viewing galaxy images is so amazing and satisfying, there are over two trillion observable galaxies in the region according to cosmologists. In order to understand if there are more galaxies nearby than they are at a distant location, I would observe them from a telescope image. Since they are of different colors depending on their location, I would count them based of these different colors. The most distant galaxies from the earth tend to be smaller in size and appear in blue-white color while the closest to the earth are red-orange in color.

The size of these galaxies will also be a guide in determining how if they are close or far from the earth and by how many kilometers. The red–orange galaxies tend to be bigger in size since they are closer than the blue-white ones which are far away from the earth.

7) A detailed step-by-step of the required evidence.

First step is to access the Hubble Space Telescope image that shows a clear variety of distant objects that can be counted scientifically.

Divide the image into four quarters to ease the counting of the objects and then multiply by four to get the amount of substances in the whole image.

After dividing the image to four quarters use a magnifying glass on that quarter to determine the images closet to the earth through their color and size.

You will realize the images that look close to you are red-orange in color while the furthest images are blue to white in color.

Record this information in a table to appreciate it better, as shown below

Phase V – Formulate a Question, Pursue Evidence, and Justify Your Conclusion

Research question

8) How does galaxy size change over time?

This question seek to understand if whether the galaxy sizes changes with time, if so how often and does the color change too.

9) The evidence will be collected from a lab through observing the universe through a telescope in every two years for a period of 20 years.

Each telescope image will be magnified to help count the galaxies, their sizes will be measured through a certain scale, and their colors recorded.

To be more accurate in this procedure we will only consider the big images since the small ones might pose a challenge in measurement.

11) Evidenced based conclusion statement

The identified galaxy were red-orange in color while the smaller galaxies were white-blue in color. From 2017 to 2025 the number of galaxies identified was reducing which could mean there earth and galaxies are rotating therefore the varying numbers of the galaxies observed from the earth. The closer the galaxy the bigger the size and the color is also red-orange. It is however assumed that the galaxies size cannot be determined fully because the distance between them and the earth is not constant, it is changing with time.

Phase VI – Summary

12) The galaxies are of different sizes and shapes, there are spiral and irregular galaxies. The size depends on the distance they are observed from the earth, the closer they are to the earth, the bigger they appear, the far they are from the earth, the smaller they appear. The closest galaxies are red-orange in color while the furthest are blue-white in color. The galaxies are distributed across the universe and they are millions of them.
