Can you see a solar eclipse?
::你能看见日食吗?Of course! This photo of a partial solar eclipse was taken on May 20, 2012 in Gilbert, Arizona. The maximum was 82% at that . Further north people experienced totality. Much of the United States experienced a total solar eclipse on August 21, 2017. The next total solar eclipse in North America is April 8, 2024 and will be visible in the US from Texas to Maine. If you try to view an eclipse, be sure to use eye protection!
::当然了!这张部分日食的照片是2012年5月20日在亚利桑那州的吉尔伯特拍摄的。 最高为82%。 更远的北方人经历了全部的日食。 2017年8月21日美国大部分地区经历了全部日食。 北美的下一个总日食是2024年4月8日, 从得克萨斯州到缅因州都将在美国可见。 如果您试图查看日食, 请务必使用眼睛保护 !Solar Eclipses
::太阳日日圆When a new moon passes directly between the Earth and the , it causes a solar eclipse ( Figure ). The Moon casts a shadow on the Earth and blocks our view of the Sun. This only happens if all three are lined up and in the same plane. This plane is called the ecliptic. The ecliptic is the plane of Earth’s orbit around the Sun.
::当新月直接在地球和日蚀之间飞过时,它就会造成日蚀(图 ) 。 月球给地球投下阴影,并阻挡我们对太阳的视线。 只有在三颗卫星都排在同一平面上的情况下才会发生。 这架飞机被称为黄昏。 黄昏是绕太阳的地球轨道的平面。The Moon’s shadow has two distinct parts. The umbra is the inner, cone-shaped part of the shadow. It is the part in which all of the light has been blocked. The penumbra is the outer part of Moon’s shadow. It is where the light is only partially blocked.
::月亮的阴影有两个不同的部分。 乳房是阴影的内部、锥形部分。 它是所有光被堵塞的部分。 月光是月光的外部。 月光只是被部分堵塞的部分。During a solar eclipse, the Moon casts a shadow on the Earth. The shadow is made up of two parts: the darker umbra and the lighter penumbra.
::在日食期间,月亮给地球投下阴影,阴影由两部分组成:暗膜和较轻的薄膜。When the Moon's shadow completely blocks the Sun, it is a total solar eclipse ( Figure ). If only part of the Sun is out of view, it is a partial solar eclipse. Solar eclipses are rare events. They usually only last a few minutes. That is because the Moon’s shadow only covers a very small area on Earth, and Earth is turning very rapidly.
::当月球的阴影完全堵塞太阳时,它就是一个完全的日食(图 ) 。 如果太阳的一部分是看不见的,那它就是部分日食。日食是罕见的事件。它们通常只持续几分钟。这是因为月球的阴影只覆盖了地球上一个很小的地区,而地球正在迅速转变。Solar eclipses are amazing to experience. The light disappears so that it's like night, only strange. Birds may sing as they do at dusk. Stars become visible in the sky. It gets colder outside. Unlike at night, though, the Sun is out. So during a solar eclipse, it's easy to see the Sun's corona and solar prominences.
::日食是令人惊叹的体验。光线消失,就像夜晚,只有奇怪。鸟儿会像在黄昏时那样唱歌。星体在天空中变得可见。外面变冷了。但与夜晚不同的是,太阳不在了。因此,在日食期间,很容易看到太阳的日冕和太阳的亮点。A photo of a total solar eclipse.
