Question

How did astronomers generate an image of Venus?

a) By sending a spacecraft to Venus with cameras and imaging equipment.
b) By using ground-based telescopes and observing visible light.
c) By capturing radar images of Venus's surface from Earth.
d) By analyzing data from the Hubble Space Telescope.

Answer 1

Astronomers generated an image of Venus by capturing radar images of Venus's surface from Earth using spacecraft and orbiters.

Step-by-step explanation:

Astronomers generated an image of Venus by capturing radar images of Venus's surface from Earth. The first global radar map of Venus was made by the US Pioneer Venus orbiter in the late 1970s, followed by better maps from the Soviet Venera 15 and 16 radar orbiters in the early 1980s. However, most of our information on the geology of Venus is derived from the US Magellan spacecraft, which mapped Venus with a powerful imaging radar.
