Yusei is my best friend.

Fuyoshi-kun, have you finished today's homework yet?

Looking up at the heavenly bodies, I feel calm.

As an astronomer, he is dedicated to the study of binary stars.

He was observing a quasar with a telescope.

Every year on July 7th is the day when the star Vega (Orihime) and Altair (Hikoboshi) meet.

The Weaver Star is shining in the summer night sky.

When I look up at the summer night sky, the Altair star is shining brightly.

The starspotted smooth-hound is a fish with a beautiful pattern like the night sky.

Finding an asterism is a great joy for astronomers.
