Twilight’s constant heavy references to astronomy are one of the things I miss from season one.

I would upvote your comment if I could.

Twinkle, Twinkle little Twi,  
How I wonder where you’ll fly,  
Up above the world so high,  
Like a diamond in the sky,
 
When the golden tree is gone,  
When he teaches for no more,  
Then you’ll show your shining light,  
Twinkle, Twinkle through the night.
 
Then your friends among the dark,  
Thank you for your tiny spark,  
How could they see where to go,  
If you did not twinkle so?
 
In the dark blue sky you keep,  
Often through the ponies sleep,  
For you never shut your eyes,  
Till the sun is in the sky.
 
As your bright and tiny spark,  
Lights the bronies in the dark,  
Though I know not what you are,  
Twinkle, twinkle, little star.
