Last night, the weather was special. I can see Orion at night. See the constellation for the first time! What other constellations can you see in winter? I am in Nanjing.

Hehe ~? Congratulations! Will you be excited when you see the constellation for the first time? Interest in astronomy often arises in this way.

In fact, there are many constellations that can be seen in winter. It's just that there are not many bright stars above 2 in most constellations, and some even have only 1. Because of the light pollution in the night sky, only second-class stars can be seen on the best days now. So most constellations are unrecognizable. Or even if recognized, there is nothing to see. For example, Canis major directly below Orion. Although there is Sirius, the brightest star in the whole day, you must have seen it last night. But the rest is too dark to see. As a result, the whole constellation became a lone star. The same is true of Taurus to the west of Orion, where only one star can be seen in the eye. Fortunately, Orion has seven bright stars above level 2. That's why you can see the whole shape. This is very rare. I think another thing to see in winter is the Big Dipper. The constellation Ursa major. Those are seven bright stars, too. You can definitely see it when the weather is fine. They will rise from the northeast horizon at 10 in the afternoon. It rises to the highest point at 4 am, due north. The whole process can be seen around Polaris. Leo can also be seen these days. It's in the east. It looks good these days because the bright Mars moves to its right. It's easy to find. It is not difficult to find Mars first. Looking in that direction, the brightest one (obviously bright) with a little orange is Mars. The lion's head is facing it. That's it:

Because of light pollution, the starry sky is not beautiful now. If you are interested in introducing your astronomical simulation software. I will never get tired of watching it. What's your name? Stellate cells? ”。 There is a search in Baidu. There are constellations and planets. Can be immediate. You can also watch it some day. It can also simulate the magnification of a telescope. Much clearer than looking at a real telescope! Try it ~
