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

Seio is my best friend.

Please imagine the day when extraterrestrials come to Earth.

A dwarf star is a star that is smaller and less bright than the sun.

The celestial pair is beautifully coloring the night sky.

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.

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

He was observing a quasar with a telescope.
