In our solar system (太阳系), some planets have a great number of moons (卫星) while some have none. Recently scientists have discovered 12 more moons going around Jupiter (木星). That means Jupiter now has a total of 92 moons, more than any other planet in our solar system.
Scott Sheppard was a member of the team that made the latest discoveries. The new moons were found using telescopes (望远镜) in Hawaii and Chile. Sheppard said, “I hope we can take clear photos of one of these moons in the near future to better understand it.”
Jupiter’s newly discovered moons are between one and three kilometers in size. They have not yet been named, as half of them are too small—less than 1.5 kilometers—to own a name.
Sheppard has already taken part in 70 moon discoveries for Jupiter. He also discovered moons going around Saturn (土星). It had been the planet with the most moons until the most recent announcement. It now is known to have 83 moons. Saturn held the top position since 2019 when Sheppard’s team discovered 20 more moons. Before that, Jupiter was the solar system’s leader with 79 moons.
Sheppard expects to keep adding moons to both Jupiter and Saturn in the future. Uranus and Neptune also have many small moons. But they are much farther from Earth, so discovering new moons around those planets is more difficult.
This year, the European Space Agency has sent a spaceship to explore Jupiter. The spaceship, called JUICE, took off in April. The task is to make further research on Jupiter and its three large moons.

【推荐1】Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. Mars carries a name of the Roman God of War, and is often mentioned as the “Red planet” because of its reddish (微红的) look. We can see it easily from Earth with our eyes.
Many pictures taken by our telescopes (天文望远镜) or spaceships show that there might be water on the surface of Mars long ago. This finding is very exciting. Because on Earth, almost everywhere there is water, there is life. That makes people think that “something” smart, or Martians, lived on the planet. So Mars has caught a lot of our imagination.
These ideas led to more stories, books, movies, and television shows than any other planet. The most famous one was the 1938 radio drama The War of the Worlds. It sounded so real that many listeners were afraid that Martians would come to Earth and take our home one day.
Television picked up on the idea of human-like Martians with the 1966 series My Favorite Martian. Other stories that took place on Mars were turned into movies such as the 1990 Total Recall and its remake in 2012. Different from the 1990 one, the 2012 Total Recall showed Mars became a planet just like the earth but the people on it lived a hard life because it got less air.
The most successful one was the 2014 novel that became the movie in 2015 of The Martian about a scientist that is left on Mars. The movie showed a complete picture of the life on Mars and got great success.
The more we know about Mars, the more stories will follow.

【推荐2】The 2022 Winter Olympics were held successfully. Athletes across the world came to Beijing and Zhangjiakou. Winter sports need to be in cold places. So, is it possible to hold the Winter Olympics on other planets?
Mercury水星
It’s the closest planet to the Sun. In the daytime, the temperature can be 430℃. At night it cools down to -200℃. There’s one area that the Sun can never reach. There’s lots of ice there. Maybe we could go speed skating there!
Mars 火星
The temperature on Mars is between -140℃ and 30℃. At the north and south poles of Mars, there are areas covered by ice and snow. Some of the ice is made of carbon dioxide, not water. There is also a big mountain called Mount Olympus. So maybe we can ski on Mars!
Pluto 冥王星
Pluto is a dwarf planet(矮行星) far away from the Sun. It’s very cold there, about -229℃. There’s lots of ice. It’s even harder than steel(钢铁). So maybe we could go sledding(滑雪橇) on Pluto.

From the moon to Mars, scientists have been looking for water — the key to life — in the solar system for many years. Recently, they have turned to Jupiter(木星)!
Jupiter is a gas giant(巨星). It doesn’t have an Earth-like surface. We can see strips(条纹) around it. They are actually cold, windy clouds.
On April 14, the European Space Agency’s (ESA) JUICE spacecraft successfully lifted off from French Guiana in South America. JUICE, short for “Jupiter Icy Moons Explorer”, will collect data(数据) from Jupiter and its three moons, Europa, Ganymede and Callisto.
The three moons are believed to have big oceans of liquid water(液态水) under their icy shells(壳). According to ESA, he water on those moons could be six times as much as the amount in Earth’s oceans. The mission “will change our understanding of the solar system”, wrote Scientific American.
In 1998, NASA’s Galileo spacecraft found that Europa might be ejecting(喷射) water as far as 160 kilometers into space. That gave scientists the idea of studying the icy moons of Jupiter.
The oceans under these moons are likely to be tens of kilometers deep. But they are also trapped under tens of kilometers of ice, making it very difficult to study them. Although JUICE cannot land on the surface, it has lots of high-tech equipment to study the moon’s environment, including spectral imaging(光谱成像) tools and radar(雷达). They could give more data on things like the thickness of the oceans, their salt content(含量), and their distance from the icy shells above, reported Phys.org.
“The main goal is to understand whether there are habitable (可居住的) environments among those icy moons and around a giant planet like Jupiter,” JUICE team member Olivier Witasse said during a press conference (发布会) on April 6.
1. What do we know about JUICE?A.It will become one of Jupiter’s moons. | B.It will collect data from Jupiter and its moons. |
C.It got its name from how it looks. | D.It left for Jupiter from the US. |
A.be six times as much as the amount in Earth’s oceans | B.be common to see on other planets |
C.have been ejected from the planet into space | D.mainly come from the planet’s icy shells |
A.lost | B.caught | C.kept | D.taken |
A.It can land and collect samples on the ground. |
B.It can get information about the oceans by radar. |
C.It can get water samples from deep under the icy shell. |
D.It can break the ice on Jupiter’s moons. |
A.To test ways of keeping water on Europa, Ganymede and Callisto. |
B.To find out if Jupiter has living things similar to human beings. |
C.To figure out if it is possible for life to live on some moons. |
D.To move water from Earth to moons like Europa, Ganymede and Callisto. |
【推荐1】Now QQ coins are popular among young man and woman. People use real money to buy Web money. Then they buy clothes for their online characters or services for their online pets with it. And these things will cost QQ fans more in the future.

【推荐2】Does eating a good breakfast improve school study? More than 1,000 students in the city of Lawrence took part in an experiment (试验) a year ago, and the answer is YES. In the experiment, students with breakfast got high scores in their tests than those without breakfast. Among those with breakfast, fewer were late for school and much fewer missed their school. “By eating breakfast, you feel active in your morning study and keep good health,” says Amy Sampson, a famous doctor. He did the experiment for a year.
Students without breakfast may lose important nourishment (营养) in eggs, fruit, bread and so on. So try to get your kids to have breakfast so that they can feel well, keep strong and do their best in the school work.

【推荐3】Hobbies are great ways to spend your time. Some hobbies can even change the way you see the world. Let’s take painting as an example.
Think for a moment about what colour clouds are. Did you think white? Take a closer look at them next time. Clouds are mostly white, but the colours also include black, grey, yellow, pink and even blue. It depends on so many factors, like what time of day you are looking at them, the type of clouds or the angle(角度) you’re looking at them. In the sunset, you’ll see many colours in clouds but you won’t see at mid-afternoon.
Painting is also a great way to notice shapes. One of the easiest ways to paint faces or objects is to break them down into their relative shapes and combine them together. Everything in the world can be broken down into things like circles, squares and triangles. It’s like putting pieces of a puzzle together as you’re creating your painting.
If you take up painting, you’ll see more colours and shapes in the world. You’ll notice subtle influences(细微的影响) of colours on evening and will be able to break anything down into their relative shapes. So everything is more beautiful than ever.
1. What colour are the clouds are?A.White. | B.Black. | C.Grey. | D.Mostly white. |
A.One. | B.Two. | C.Three. | D.Four. |
A.Always look them as a whole thing. |
B.Always break them down into their relative shapes. |
C.First break them down into their relative shapes and then combine them together. |
D.First combine them together and then break them down into their relative shapes. |
A.in the morning | B.at mid-afternoon. |
C.in the afternoon | D.in the sunset |
