We use telescopes or satellites

Mainly astronomers. But cosmologists and astrophysicists will also be interested in outer space.
Yes, pencils occupy space because they are physical objects that have mass and volume. When a pencil is placed in a certain area, it displaces the air and occupies that space.
Their eyes, ground-based telescopes, space telescopes.

to get every view
they use space probes,satellites,and of coarse,telescopes.

Mechanical pencils, like the regular kind of pencils, use graphite.
