- Mars has the largest volcanoes in the solar system. (T/F)Astronomers solved this puzzle when they observed a rare transit of Venus in front of the Sun (Figure 5). What could they learn about the planet’s atmosphere from this photo?Eventually, space telescopes have shown that Venus is shrouded by a very dense atmosphere (see Figure 6). To pierce through the dense clouds and study its surface, astronomers had to use radio imaging (see Figure 7). Venus’ atmosphere is transparent to radio waves. Research and explain briefly how, through radio imaging, Venus’ surface could be reconstructed.
- If you visited a planet in another solar system and discovered that it was heavily cratered, but its small moon was nearly crater free, why would that be a surprise? Speculate about what might have happened to those objects.Saturn is even further at 1434X109m from the sun. Calculate the approximate strength of the greenhouse effect on Jupiter. The observed surface temperature is 133K, the albedo is 0.47, the solar constant is 15W/m2.(b) Show that the equilibrium temperature of Venus is right for liquid water, given that it lies = 3.85 × 1026 W) and assuming a at a distance of d = 1.09 × 108 km from the Sun (Lo mean albedo of 0.45. Explain why, in reality, Venus is too hot for liquid water.
