Because there are these thick clouds that always surround Venus, so they need radars to see past the clouds.
What else can I help you with?
Why do scientist need to use radar to study Venus' surface?
Scientists use radar to study Venus' surface because its thick atmosphere makes it impossible to see the surface with visible light. Radar can penetrate through the clouds and provide detailed images of the planet's surface features, allowing researchers to study its geology, topography, and other characteristics.
How can the surface of Venus' be observed with?
The surface of Venus can be observed using radar imaging from spacecraft orbiting the planet. Radar can penetrate through the thick clouds covering Venus and provide detailed images of its surface features. This method has been used by missions like NASA's Magellan spacecraft to map the surface of Venus.
Which planet did the spacecraft Magellan enable scientists to research extensively?
Venus was the planet that the spacecraft Magellan enabled scientists to research extensively.
Why was the planet venus imaged using radar?
The planet Venus was imaged using radar because its thick atmosphere makes it difficult to observe the surface using optical telescopes. Radar can penetrate the clouds and provide detailed images of the planet's surface features. Additionally, radar can also measure the surface elevation and map the topography of Venus.
Our model of the surfaces features of venus was obtained by?
Our model of the surface features of Venus was obtained by the radar.
Why was necessary to use radar to produce an image of venus surface?
Venus has a dense cloud layer, so regular light doesn't get through. Radar could get through and give an image of the Surface.
How have we been able to construct detailed maps of surface features on Venus?
Radar has been used to map the surface of Venus
Why can surface of Venus not be seen?
The surface of Venus can not be seen in optical light due to an immensely think atmosphere. However, it can be seen by radar and because of this most of the planet has been mapped.
The planet closest to the sun to have satellite?
Venus has two artificial satellites orbiting it, radar-mapping the surface and gathering other useful information about its surface.
When did scientists discover that Venus turns the other way than most planets?
Scientists discovered that Venus rotates in the opposite direction to most planets (known as retrograde rotation) in the 1960s through observations made with radar mapping. This discovery was a significant finding in the study of Venus and planetary science.
Has Venus been observed closely by humans?
The surface of Venus is unobservable due to the thick cloud cover. Some Russian Venera spacecraft have landed there to get a glimpse of the rocky surface, and the entire planet has been mapped by radar.
How do scientists know what the surface of Venus looks like?
Scientists know that there are volcanoes on Venus because images from satellites show features like rivers. Since Venus is too hot to have water, the rivers are more likely flowing lava.
