A website that I enjoy visiting is Stellarium. It's an astronomy website, and it's a website or an application that you can use in your computer or in your cellphone. Stellarium can be used to observe the universe and to observe the things that are in it.
In this website you can observe an accurate simulation of the stars, planets, contellations and satellites in the universe. You can point to the sky with your cellphone to discover stars or planets that you can't seen with tha naked eye, even if you see something in the sky and you don't know what it is, you can point it with your cellphone and Stellarium will tell you what it's called. In the same way you can observe the constellations and you can discover their names and thir shapes.
On the other hand, you also can enlarge the image of the planets and satellites and there will be a descrption about them. Additionally, you can explore the surface of the moon and observe it's cycle.
Lastly, this website can be used at any time, even you can see what the universe was like centuries ago and how it has been modified to reach the present day.
I discovered this website this semester, because I must observe the moon for one month and in the cloudy days, when I can't observe the moon, I used Stellarium to observe it. So I visited this website frequently for a little bit more one month.
I like this website and I recommend it, because I think that is very realistic and you can see things that you normally wouldn't be able to see, because they are very far away. It's also a great source of information.
The link for the website is: https://stellarium-web.org/
I hope you like and it helps you.
