Scientists these days are able to see the photosphere in fantastic detail using powerful telescopes.

科学家现在可以用先进的天文望远镜来观测光球层细微而神奇的变化。

So instead of landing on the photosphere, you're going to sink into it.

因此，你不会降落在光球上，而是会沉入其中。

But once it reaches the sun’s surface – the photosphere – it can escape.

光能一旦到达太阳表面，即太阳的光球层，就会与之脱离。

Then it travels onward to the photosphere where it emits heat, charged particles, and light.

然后它向前移动到光球层，在那里它释放热量、带电粒子和光。

And the next layer is just as perilous: The photosphere.

而下一层也同样危险：光球。

One of the biggest dangers in the photosphere comes from these enormous black spots you can see as you look around.

光球中最大的危险之一来自于四周这些巨大的黑点。

It's less than 1% as dense as the photosphere, but actually much hotter; temperatures there can reach over a million degrees!

它的密度不到光球层的1%，但实际上要热得多；那里的温度可以达到100多万度！

Above the convecting layer is a much thinner, cooler layer very near the Sun's surface called the photosphere, or literally the sphere of light.

对流层之上是一个更薄、更凉、非常靠近太阳表面的光球层，它是字面意义上的光构成的球体。

The Sun is a gas and doesn't have a solid surface, but the gas in the photosphere thins so rapidly compared to the Sun's huge size that you can think of it as the Sun's surface.

太阳是一种气态星球，没有固体表面，但与太阳的巨大体积相比，光球层的气体密度下降得非常快，与内部差异显著，以至于你可以把它看作是太阳的表层。
