那棵树上发生了什么？两个完全不同的东西。左边是仙女座星系，这是一个比人类更古老的天体，它将在未来存在数十亿年。仙女座星系（M31）在大小和形状上与我们的银河系相似。右边是一个红色的精灵，一种持续不到一秒的闪电，出现在猛烈的雷暴之上。红精灵被证实为真实的大气现象大约在35年前。中间的树是一棵树，它可以活一千年。Boab树自然生长在澳大利亚和非洲，以能够储存大量的水而闻名：高达10万升。这张特色照片是上个月在西澳大利亚的德比附近拍摄的。

What’s happening over that tree? Two very different things. On the left is the Andromeda galaxy, an object that is older than humanity and will last billions of years into the future. Andromeda (M31) is similar in size and shape to our own Milky Way Galaxy. On the right is a red sprite, a type of lightning that lasts a fraction of a second and occurs above violent thunderstorms. Red sprites were verified as real atmospheric phenomena only about 35 years ago. The tree in the center is a boab, which may live for as long as a thousand years. Boab trees grow naturally in Australia and Africa and are known for being able to store large amounts of water: up to 100,000 liters. The featured image was captured last month near Derby in Western Australia.
