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.arrow_forwardAstronomers are always seeking to build bigger, more powerful telescopes, which will allow them to study faint galaxies that are very far away. Which of the following is the main reason they're so obsessed with studying very distant galaxies? Group of answer choices Light traveled much faster during the early history of the universe, so we can study how the speed of light has changed through time. Very distant galaxies are more likely to contain planets than the Milky Way is, so we have a better chance of detecting life in those galaxies than we do in our own galaxy. Since the light from these galaxies took so long to reach us, we're seeing them as they were when the universe was very young. Strangely, distant galaxies are more like our Milky Way than the Milky Way's `neighbor' galaxies are, and astronomers would like to figure out why this is.arrow_forwardq4 1, 2, 3arrow_forward

Ignore the one about proboblilty please.arrow_forwardUsing MBH = 6.6 × 10 Mo, calculate the below. a. Find radius of the Schwarzschild sphere (Schwarzschild radius Rs). You can calculated from the appropriate formula or just use the fact that for an object of 1 solar mass Rs = 3 km. b. Express Rs in km, in AU, in parsecs. c. Using the distance to M87 and your result above, find angular radius of the SMBH (Schwarzschild radius). Express it in arcseconds (") and micro- arcseconds (pas) d.
