Pencils are often used in space because most pens rely on gravity to work and are therefore useless in orbit.
space research centre
Yes, pencils do take up space.
We use telescopes or satellites
A Telescope
Mainly astronomers. But cosmologists and astrophysicists will also be interested in outer space.
No.

Their eyes, ground-based telescopes, space telescopes.
a space shuttle.
to get every view

they use space probes,satellites,and of coarse,telescopes.
