Read the questions slowly and answer with precise and long details about each of the questions. Answer correctly and follow my guidelines for a long and wonderful review after results. Your target/main observable galaxy is the whirlpool galaxy. Target: Whirlpool Galaxy Object Type: Galaxy Distance: 37 million light-years Constellation: Canes VenaticiDO NOT COPY AND PASTE OTHER WORK OR THINGS FROM THE INTERNET, use your own words. In 500 words, compare and contrast the specific object to at least 2 other objects in its sourceclass (eg. if it's an isolated star, to different types of isolated stars). Explain both observational andphysical differences, as well as what the comparison teaches us about the source class in general.
Astronomy Question:  Read the questions slowly and answer with precise and long details about each of the questions. Answer correctly and follow my guidelines for a long and wonderful review after results. Your target/main observable galaxy is the whirlpool galaxy. Target: Whirlpool Galaxy Object Type: Galaxy Distance: 37 million light-years Constellation: Canes VenaticiDO NOT COPY AND PASTE OTHER WORK OR THINGS FROM THE INTERNET, use your own words. Provide refernces if used In 500 words, please explain the relevance of this object to the physics course material in university andits importance to astronomy. (Some question you may seek to answer are: What beyond the objectitself is learned by studying this class of objects? What sorts of telescopes and observations would beneeded for more detailed, broader reaching studies of this source and objects of its nature?)
For the picture below what is the differences of light spectra of different galaxies. compared to a laboratory reference to uses as comparison, or control group. What is the differences between nearby stars and galaxies compared to distant stars and galaxies by using the spectral lines ?
