Venus (金星) is close to the Earth. It is the second planet from the Sun. The Earth is the third planet from the Sun. Venus is similar (相似的) to the Earth in size and mass (质量). So people often describe it as “the Earth’s sister planet”.

Scientists have been learning about Venus for a long time. First, they looked at Venus through telescopes (望远镜). But Venus is covered with thick clouds. Scientists could not see Venus well through the clouds. So they made guesses at it.

For a long time, scientists thought that Venus had water and plants. They thought Venus might have animals too. But they didn’t know for sure.

Then scientists found a way to learn more about Venus. In the 1960s, they began sending probes (航天探测器) to Venus. The probes flew through the thick clouds. They took pictures of Venus up close. They found out many things too. The probes sent the pictures and things they found out back to the scientists.

Is there life on Mars? We don’t know.

We’re sure that people on the earth are not able to live on Mars. People need oxygen to breathe. There is almost no oxygen on Mars.

Living on Mars would be like living on a very high mountain. There would be little air.

The temperature might be 50 degrees above zero at noon and 140 degrees below zero at night. Many people think there may be plants on Mars. We know that on Mars there is carbon. This is a kind of material found in all plants and animals on the earth. Through a telescope, Mars looks red. In some places, it seems gray. At times the gray color turns gray-green, then brown, then gray again. The gray-green color may be a kind of plant life changing color with the seasons.
