Local Group. The Andromeda Galaxy‚ a spiral galaxy closet to our solar system‚ is now known to be the edge and rim of our Milky Way. Even though the Andromeda Galaxy is bigger than the Milky Way Galaxy‚ both of these galaxies have many similarities. Astronomers in today’s world base their scientific observations off of the Andromeda Galaxy to make assumptions about the Milky Way. Astronomers have concluded that the Andromeda Galaxy‚ or M31‚ is about 2.5 million light- years away‚ with the entire galaxy

discovery of galaxies outside of the Milky Way‚ the expanding universe‚ and overseeing the construction of the Hale Telescope. Because of his major contributions to the study of Astronomy‚ the Hubble Space Telescope was named after him in 1990. One of Hubble’s first discoveries was that there are other Galaxies outside of our Galaxy‚ the Milky Way. In the 1920s‚ the small‚ diffuse patches in the sky were termed nebulae‚ and were thought to exist within the Milky Way. While examining images of the galaxies

it can inspire our lives. Wordsworth uses images to describe the scene to the reader‚ like a painting on a canvas; that explains vividly how the poet saw it. An example of the creativity is how the daffodils presented an almost human quality in the way they resemble dancers dancing in unison as if presenting a show. At the end of every alternate line of the poem there is a rhyming word‚ giving the poem both continuity and a sense of rhythm throughout. For my conceptual analysis I chose ‘nature thrives

If an inhabitant of the host galaxy of that quasar looked at the Milky Way at the same time we looked at their galaxy‚ what kind of object might they see? Explain. How would the color of light they observe be different than the color of light emitted by the Milky Way? Explain. 2. What is Hubble’s Law and how can it tell us the distance to a galaxy?

the Great Andromeda Nebula in older texts. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy‚ but not the closest galaxy overall. It gets its name from the area of the sky in which it appears‚ the constellation of Andromeda‚ which was named after the mythological princess Andromeda. The Andromeda Galaxy is the largest galaxy of the Local Group‚ which also contains the Milky Way‚ the Triangulum Galaxy‚ and about 30 other smaller galaxies.
