The Large Magellanic Cloud is a small satellite galaxy that orbits the Milky Way. It is currently orbiting the Milky Way at a distance of about 160,000 light-years from the galactic center at a velocity of about 300 km/s. Use these values in the orbital velocity law to get an estimate of the Milky Wayʹs mass. (The value you obtain is a fairly rough estimate because the orbit of the Large Magellanic Cloud is elliptical, not circular.)
Different wavelengths (frequencies) of light let us see different aspects of the galaxy, which type of light is best for the followingcomponents of the Milky Way? A) Radio -> Cold gas; Visible -> Stars; X-rays -> Hot gas; Gamma-rays -> Cosmic rays B) Radio -> Stars; Visible -> Cold gas; X-rays -> Hot gas; Gamma-rays -> Cosmic Rays C) Radio -> Hot gas; Visible -> Stars; X-rays -> Cold gas; Gamma-rays -> Cosmic Rays D) Radio -> Cold gas; Visible -> Cosmic Rays; X-rays -> Hot gas; Gamma-rays -> Stars
The image below combines visual (blue) with radio (red) to show the galaxy radio astronomers call Fornax A. Explain the features of this image. Is it significant that the object is a distorted elliptical galaxy in a cluster?
