NASA's Alex young says that solar scientists welcome the annual lean.

美国宇航局的亚历克斯杨说，太能科学家欢迎每年的精益测量。

Probing these phenomena will help scientists understand the turbulent space weather created by the sun.

探索这些现象将有助于科学家理解太造成的荡太空天气。

In the early nineteenth century, scientists assumed that the Sun worked just like any fire on Earth, that there was a source of fuel, perhaps coal, that was slowly burning away.

在19世早期，科学家假设太就如同地球上的任何火一样，有来自象煤这样的燃料，慢慢地燃烧。

The spacecraft will have to deal with extreme heat and radiation levels as it moves closer to the surface. However, the probe is expected to make observations that will add to scientists' understanding of the Sun.

航天器更靠近太表面，就不得不应对极高的热量和辐射。但预计该探测器观测到的信息可增加科学家对太的了解。

Solar scientists say the good news is that it will be less intense than the most active cycles of past centuries.

太科学家说，好消息是，这次太的强度将低于过去几个世最跃的太周期。

When astronomers started finding planets outside our Solar System, or exoplanets, we realized that there are many worlds out there.

当天文学家在太系外发现了行星，也就是系外行星，我们意识到太系外有许多星球。

One of the main reasons some scientists support solar geoengineering is that we're currently on a pretty dire path.

一些科学家支持太能地球工程的主要原因之一是，我们目前正处于一条相当可怕的路上。

Scientists observing the Sun have a few hours, up to a few days, to see a CME coming.

观察太的科学家们有数小至几天的间才能看到一场CME的来临。

However, the probe is expected to make observations that will add to scientists' understanding of the Sun.

然而，该探测器预计将进行观测，增加科学家对太的了解。

Why do scientists believe the Sun was born from the ashes of a supernova?

为什么科学家认为太是从超新星的灰烬中诞生的呢？

And space scientists have discovered a planet just outside our solar system that might host life.

空间科学家在太系外发现了一颗宜居类地行星。

Scientists have discovered that the sun helps monarchs find the right direction to go.

科学家发现太帮助帝王蝶找到正确的方向。

Even if it turns out Planet Nine isn't there, Lawler says, it has sparked a lot of useful interest in the outer Solar System from astronomers.

Lawler 说， 即使事实证明第九行星不存在， 它也引起了天文学家对太系外层的许多有益兴趣。

But other suns, stars as the astronomers call them, are bound to have planets like our own, and as is the number of stars in the universe is so vast, this possibility becomes virtual certainty.

但是，其他的太，既天⽂学家所说的恒星，肯定会有像我们地球⼀样的⾏星。因为宇宙中恒星的数⽬极其庞⼤，所以存在着产⽣⽣命星球的这种可能性是肯定⽆疑的。

When later European astronomers wrote about sunspots, they didn't believe that the spots were actually on the Sun.

当后来的欧洲天文学家写到太黑子，他们不相信这些黑子实际上在太上。

Another astronomer named Wolf kept track of the Sun for an even longer period, 40 years actually.

另一位名叫沃尔夫的天文学家跟踪太的间更长， 实际上是 40 年。
