When I was a kid，I got interested in astronomy（天文学），I often watched northern lights in my hometown in Lapland．I used to wonder how big the___ might be and what are"behind"the stars．But as I grew up and finally went to college，I hardly had any time to develop my hobby because of too much homework．It was in 2009that I rediscovered astronomy．I found an astronomy magazine in a library and immediately I got interested in astronomy again．
When I start reading astronomy books and magazines，I start finding out how many interesting things there are outside the planet．I realize that the information I am reading，hearing and watching opens a door to a huge world of interesting things．
However，I do not have much time for my hobbies．Many times I would like to observe an object in the night sky，but I am working or I have to look after my kids．So I share my hobbies with my kids．I encourage them to observe the stars together with me．I need kids'astronomy books for them and tell them about the moon，stars，the sun and many other interesting things．We all find it interesting at the same time．
I enjoy astronomy as a hobby and I hope other parents like me can read book and magazines about it．Just imagine that you and your family sit together watching the stars and talking in the yard on a summer night!How cool it will be!
