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.

Interstellar travel is still a realm of dreams for mankind.

A meteor shower poured down in the night sky, and I was breathless at its beauty.

Hachiboshi is my best friend.

The starlight is beautifully illuminating the night sky.
