Explain why we see the Milky Way as a faint band of light stretching across the sky.

Expert Solution & Answer

To determine

To explain:

The reason for the Milky Way to be visible as a faint band of light across the sky.

Explanation of Solution

Milky Way is the home galaxy to the Solar system. Milky Way is a spiral shaped galaxy and contains hundred billion stars. It is about 13.5 billion years old. It is about 30 kpc in diameter.

Solar system lies in the outer regions of the Milky Way in the Orion arm of the Milky Way galaxy. The galactic center if about 8.4kpc away from the Sun.

It is named as Milky Way because of its appearance in the night sky. It appears as a hazy white band of clouds with billions of stars embedded in it. From the Earth, the other arm of the Milky Way is visible. That is why, it appears as a band of stars.

Let’s say you’re looking for extrasolar planets. You observe a star that has a spectral shift in the line that is supposed to be at at 656.28011 nm – this star shows this line at 656.28005 nm. What is the radial velocity of star (in m/s) and in what direction in relation to you? a) 27.4 m/s, towards b) 27.4 km/s, away c) -27.4 m/s, toward d) -27.4 km/s, away

1. A distant galaxy has an apparent magnitude of 10 and is 4,000 kpc away. What is its absolute magnitude? (Round your answer to at least one decimal place.) The difference in absolute magnitude between two objects viewed from the same distance is related to their fluxes by the flux-magnitude relation. FA/FB= 2.51(MB − MA) 2. How does the absolute magnitude of this galaxy compare to the Milky Way (M = −21)?

Write down the Doppler formula for light as an equation. Explain each letter's meaning. Then compute what the relative change in the wavelength of emitted light would be for a galaxy moving at a velocity 10.99 kilometers per second away from the Milky Way galaxy
