Galaxies IINameInstitutional AffiliationGalaxies IIQuestion 1Cepheid variables are dazzling, and those at much distance can be observed and measured. When the period of a distant Cepheid has been measured, its glow can be resolved from the known conduct of Cepheid variables. It distance can be calculated by a relationship of the apparent and the actual (absolute) magnitude with the modulus equation. Question 2NGC 1316: After Galaxies Collide Image. Hubble, the Observatory, is the first major optical telescope to be placed in space and was used in the observation. The image is “face on” and was observed FOC in high-resolution mode through several filters Question 3 Spiral galaxy. The picture shows the galaxy from a side, and therefore this is an "edge-on spiral" type of galaxy. It is recognized as edge-on spiral galaxies because bright central bulges can be observed. Approximately 77% of most perceived galaxies are spiral galaxies in the universe. Our galaxy is an example of a spiral galaxy in the Milky Way.Question 4 part 1NASA's Fermi Gamma-ray Space Telescope establish a signal in the middle of the nearby Andromeda galaxy that could identify the
