Space exploration is always a fascinating topic. We study celestial bodies（天体）like stars, 31 , and comets because of our curiosity. Stars, for example, are huge balls of gas that give off light and heat. They play an important role in the universe. Some stars are so 32 that we can see them even with our own eyes at night.
Planets, on the other hand, 33 around stars. Each planet has its own features. Mars, for example, is often called the “Red Planet” because of its red color. It is a hot spot（热点） of space exploration 34 scientists think there was life on it.
Comets are 35 objects in space. They are made of ice, dust, and small rocks. When a comet gets close to the Sun, it heats up and forms a long, bright tail. This makes it look very
36 other celestial bodies.

John Smith an hour ago Recently, we’ve found evidence（痕迹）of water on Mars. This discovery has increased the possibility of finding life on the planet. We are also studying the rings of Saturn more closely with other scientists. We’ve found that the rings are much more complex than we thought.
Jane Green yesterday There’s a new theory about Jupiter’s Great Red Spot（大红斑）. Some scientists think it might be shrinking（缩小）. They’re using powerful telescopes to monitor its sizes, colors and changes in its behavior.
Tom Ruskin two days ago The James Webb Space Telescope has been sending back amazing images from distant stars and galaxies. It might also help us learn more about the outer planets in our solar system, like Uranus and Neptune.

Mercury is the closest planet to the Sun. It is also the smallest planet in the solar system. Because it is so close to the Sun, it has extreme（极端的） temperatures. During the day, the temperature on Mercury can reach up to 430°C, but at night, it can drop to -180°C.
Mercury has a very thin atmosphere. It is mostly made up of helium and sodium（氦和钠）. It has a rocky surface with many craters（陨石坑）, similar to Moon. These craters were formed when asteroids（小行星） or meteoroids（流星体） hit the planet.
Mercury has a very slow rotation（自转）. It means a day on Mercury is much longer than a day on Earth. In fact, a day on Mercury is about 59 Earth days long. However, its orbit（公转） around the Sun is very fast, taking only about 88 Earth days to complete one.
Scientists sent probes（探测器） to Mercury to study it more closely. These probes helped us learn about its magnetic field（磁场）, surface composition, and other features.

Pluto is a fascinating dwarf planet（矮行星） in our solar system. It’s known for being one of the farthest objects from the Sun. It takes Pluto about 248 years to go around the Sun once and it takes the light more than 5 hours to travel from the Sun to Pluto.
Pluto is very cold, with temperatures reaching as low as -230°C. It is made of rock and ice. Its surface is covered with mountains and plains. Although it’s small in size, Pluto has five known moons.
Pluto was once the ninth planet in our solar system. However, in 2006, it was reclassified（重新归类） as a “dwarf planet” because of its small size and unusual orbit.
Scientists are still interested in Pluto. They want to learn more about its origin（起源） and how it formed. In 2015, scientists sent a space probe called New Horizons to explore Pluto and provide us with valuable information. It took many pictures of the planet and brought them back to Earth.

We can see many stars in the night sky. They come in different sizes, colors, and temperatures. The color of a star is related to its temperature. Blue and white stars are the hottest, while red stars are the coolest.
Stars are born in huge clouds of gas and dust called nebulae（星云）. Gravity causes the gas and dust to come together and form a dense core（核心）. As the core gets hotter and denser, nuclear fusion（核聚变） starts, and a star is born.
Stars have a lifespan（寿命）. When a star runs out of fuel（燃料）, it goes through different stages of death. Some stars explode in a huge supernova（超新星）, while others gradually cool down and become white dwarfs（白矮星）.

听下面一篇短文，根据你所听到的内容，在信息表中相应的横线上填入所缺信息，每空限填一词。短文读两遍。
Venus is close and similar to Earth. It is often described as the sister of Earth. Scientists have studied Venus for a long time since 1961. In the past, they thought there was water, plants and animals on Venus. But now they find that the temperature is so high that there isn’t any water or living things. There are only mountains and volcanoes. The sky on Venus is yellow and orange. It’s because of its thick clouds. Until now, scientists have sent over 40 machines into space to watch Venus and they hope to learn more about it.

My Favorite Planet—Jupiter
Jupiter is the biggest planet in our solar system. It’s much larger than all the other planets together.
There is one thing very special on Jupiter—the Great Red Spot. It’s a huge storm. This storm lasts for a long time. Jupiter has many moons. One of its moons is called Europa. Scientists think there may be liquid water on Europa. Water is very important because where there is water, there might be life.
Scientists like Jupiter a lot. They study it all the time. They want to know more about Jupiter and the universe. I like Jupiter too. It’s so interesting and there’s so much to learn about it.
