- The planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…Despite being composed primarily of gas, Jupiter and Saturn have large magnetic fields. This is primarily due to the presence of _________________ beneath its cloud tops.If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshifted and light from the other edge blueshifted. If you observed a spectral line at a wavelength of 505 nm, what difference in wavelength (in nm) should you expect between the opposite edges of the rings? (Hints: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity,
- In the Transit method for detecting exoplanets, how many dips of light from the star need to be detected for it to be a successful detection of an exoplanet?If Neptune's clouds have a temperature of 60 K, at what wavelength will they radiate the most energy?If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshift and light from the other edge blueshift. If you observed a spectral line at a wavelength of 525 nm, what difference in wavelength (in nm) should you expect between the opposite edge of the rings? (Hint: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity and the formula for the Doppler shift.) _______ nm
