Mangas based of space or stars

I don’t remember if it was specifically about stars or not but I remember enjoying it and a beautiful scene of the stars and it was a big part of it and a big part of seeing just how wonderful life is.

Haven’t personally read this, but it has star in the name lol. I heard it’s a masterpiece and it has a few free eps on webtoon if you want to support the author
