24 The Night Jupiter Surprised Me I enjoy looking at the night sky with my telescope.

24 夜木星惊叹 我喜欢用望远镜看着夜空

But I’ve found that most things you see through a telescope appear the same every time you look at them.

我仍然记得我对这个发现有多兴奋,

I saw Jupiter change again, right before my eyes, in July 1994.

1994年7月,我再次看到木星在眼前改变。

It was the last night that big chunks of a broken-up comet—called Comet Shoemaker-Levy 9—collided with the planet.

这是最后一晚,一颗被破碎的彗星——所谓的 " 鞋匠-莱维9号彗星 " 与地球相撞。

I saw several dark “bruises” on Jupiter where the chunks of the comet hit.

我在木星上看到多起暗黑的"血",

I drew pictures of these, too, as I thought about how cool it was to see them through a telescope.

Weather Report from Jupiter Have you heard the weather report from Jupiter today?

木星的天气报告 你听到木星今天的天气报告了吗?

I heard reports of average temperatures of about –236 degrees Fahrenheit (–149˚C).

我听说平均气温大约为-236华氏度(–149-C).

Seeing Jupiter from Space The Hubble Space Telescope has been used to take many sharp photographs of Jupiter and the other planets, as well as galaxies and other objects in deep space.

从太空看到木星 哈勃太空望远镜被用来拍摄木星等行星以及星系等深空物体的许多尖锐相片.

This telescope is able to take very detailed pictures because it orbits Earth high above the atmosphere.

这种望远镜能够拍摄出非常详细的照片,因为它环绕地球在大气层上方高地运行.

(The high orbit allows the telescope to avoid the blurring that the atmosphere can cause in photos taken from the ground.)

(高轨道允许望远镜避免大气层在从地上取取的照片中可能造成的模糊.

Astronauts on the space shuttle Discovery placed the Hubble Space Telescope in orbit in 1990.

1990年航天飞机"发现"号上的宇航员将哈勃太空望远镜放入轨道.

After several additional space shuttle missions to give the telescope new equipment, it was still working in 2006.

哈勃太空望远镜在轨道上截取了Ganymede Ganymede (GAN-uh-meed) 是木星最大的月球, 也是整个太阳系中最大的月球。

Its surface has many mountains, valleys, and craters, as well as ice mixed with rock.

其地表多有山地,山谷和陨石坑,也多有由岩石混合而成的冰.

Callisto Callisto is covered with many craters, which were made when comets and asteroids crashed into the moon.

Like Europa, Callisto may have an ocean of salty water under its surface.

和欧罗巴一样,卡利斯托可能在其地表下有咸水出海.

Revolutionary Discovery Galileo (1564–1642) made the first important discoveries with a tool that was new during his time— the telescope.

革命发现伽利略(1564–1642)用他时期的新工具——望远镜——进行了第一次重要发现.

Before Galileo used a telescope to discover the four largest moons of Jupiter in 1610, many people believed that the planets and the Sun revolved around Earth.

在1610年伽利略用望远镜来发现木星的四颗最大的月球之前,许多人认为这些行星和太阳围绕地球相绕.

Galileo’s discovery that there are moons revolving around Jupiter was the first evidence that not everything moves around Earth.

伽利略发现在木星周围有月球旋转,这是第一个不是一切在地上运动的证据.

This discovery helped persuade other scientists that Earth and the other planets move around the Sun.

这一发现有助于说服其他科学家,地球和其他行星围绕太阳运动.

These volcanoes shoot out hot plumes of sulfur dioxide gas and bubbling flows of melted rock (lava).

这些火山喷出热的二氧化硫气体和熔岩(拉瓦)的流出.

Different kinds of chemicals in the lava flows make different colors all over Io’s surface, including yellow, red, orange, and green.

Deep cracks run through the ice, dividing it into large chunks that are like icebergs on Earth, only Europa’s icebergs are the size of Earth’s cities!

深层裂缝会穿过冰层, 将冰块分割成大块,

Underneath the cold, cracked ice, there may be a deep, dark ocean of warm water.

在寒冷而破碎的冰下, 可能有一个深暗的海水 温暖的水。

Scientists think that if this ocean really exists, alien creatures may live in it.

科学家们认为,如果这个海洋真的存在, 外星人可能生活在其中。

The Rings of Jupiter People used to think that Saturn was the only planet with rings around it because its rings are the only ones that can be seen through a telescope on Earth.

木星人之指环曾认为土星是唯一有环绕的行星,因为它的环是地球上唯一能通过望远镜被看到.

So scientists were surprised in 1979 when cameras on the Voyager spacecraft, which was flying near Jupiter at the time, took pictures of rings around the planet.

1979年,当时飞行在木星附近的Voyager航天器上的相机拍摄了环绕行星的照片,科学家对此感到惊讶.

The pictures from Voyager showed that Jupiter has four rings that are much thinner than the rings of Saturn.

Voyager的照片显示,木星有四个环比土星的环要薄得多.

Unlike Saturn’s rings, which are made partly of large chunks of ice, Jupiter’s rings consist of tiny particles of dust.

与土星环不同,土星环由大块冰所组成,木星环由微小的尘粒组成。

Scientists think that Jupiter’s rings formed when meteoroids crashed into the planet’s moons.

科学家认为,当流星体坠入行星的月球时,木星的环会形成.

These crashes threw dust into space, and this dust collected into rings.

这些撞击把尘埃扔入了太空 尘埃被收集成环状

Do You Know?

你知道吗?

Two main kinds of telescopes are the refracting telescope and the reflecting telescope.

两种主要望远镜是折射望远镜和反射望远镜.

A refracting telescope uses a large lens to focus light rays from an object to a point inside the telescope.

折射望远镜使用一个大透镜来将光线从一个物体聚焦到望远镜内部的一个点.

A reflecting telescope focuses light rays with mirrors.

反射望远镜将光线射出镜面。

With either kind of telescope, you look at the focused point of light rays through an eyepiece to see a magnified image of the object.

用任何一种望远镜,你通过一眼镜来观察光线的聚焦点,看到物体被放大的图像.

Do You Know?

你知道吗?

Jupiter’s spin is slowing down because it is being pulled by the gravity of its moons.

木星的自旋因被它的月球引力所拉动而减慢.

The same thing is happening to Earth because of its moon!
