In an article, published on astronomy.com called “Finding The Milky Way’s Hydrogen Halo” by Alison Klesman perfectly fits in with our 15th conceptual objective on the structure and size of the Milky Way Galaxy. To begin, the article talks about how our galaxy and many other galaxies are missing Baryonic Matter. The article explains bayonic matter is the matter that is basically everyday matter around us because it matter that is consisted of protons and neutrons. The article further explains that recent observations were made that leads to the possibility of galaxies being able to host a diffuse of gas at greater distances. In contrast, this relation would make up the missing matter that astronomers are not able to put their finger on. Next, the article talks about how exactly scientists are trying to find these hydrogen halo’s in our galaxy to find this missing baryonic matter through the different usages of sky surveys. Furthermore, the article tells us through these sky surveys they are are studying the spectra that would be able to track the qualities of light and how light would function doing through a hydrogen halo. To conclude, the article talks about how they need to host more sky surveys, more different kinds of observations, and do more comparisons toward studying the spectral with interactions to the halos to get a better feel for these hydrogen halo’s.
This article fits in with our 15th conceptual objective perfectly because inside this article it talks about the many different parts and what are galaxy is made out of. In, the article it discusses that these hydrogen halos are over thousands of light years long and they go on even to further distances. This can exactly relate to the massive size of our galaxy that simply a hydrogen halo is able to stretch that long of a distance within our galaxy. Also, the article talks about how galaxies including the Milky Way galaxy are about to host a diffusion of gasses at greater distances furthering the maintainability of how massive our galaxy is. This can be compared in our lectured-tutorial called “Milky Way Scales” in that in the lectured-tutorial it teaches us that the Milky Way is about 100,000 ly within the width and 50,000 ly from the center to the edge. This connection is able to serve an idea of big our galaxy really is. Also, the article talks about the Milky Way Galaxy consists of a bulge at the center of the galaxy, disk, and its own halo. The galaxy is also known as a spiral galaxy based on the fact the galaxy has spiral arms. Lastly, the galaxy is most comprised with dusts, stars, and cosmic gasses. The dust and gases mostly come from when stars die, star creation, and also stellar evolution.
To conclude, from the article we are able to fully grasp the size and structure of the Milky Way galaxy. In, the article it represents how massive the size of the galaxy is through the usage of describing how big hydrogen halo’s are. We are then able to compare this to our lectured-tutorial on the width of our galaxy and the size from the center towards the edge of our own galaxy. One, thing I learned from this objective even though in retrospect from us that our galaxy is absolutely massive but to retrospect with the universe its only on a speck of the scale because of the universe is filled with galaxies. Overall, from the lectured-tutorial, article, and many class discussions I now how a better understanding on how massive our galaxy is and the structure within the galaxy.
