Why are radio telescopes so BIG?
Cause they want to be JEEZ
to collect more radio
To collect their huge wavelengths
What type of telescope can work 24 hours a day and even be used in the rain?
Refracting Telescope
Radio Telescope
Newtonian Telescope
Solar Telescope
What types of telescopes have to be placed in space? (Choose all that apply)
X-ray Telescopes

Why must Ultra-Violet observing be done in space?
The ozone blocks most of the UV rays in the surface.
It’s hard to know exactly where the ozone hole will be to find UV images
It’s hard to use UV telescopes and radio telescopes together on the surface.
So that the astronomers using it won't get a sunburn.

The Keck telescope has a 10 m diameter mirror. The SALT telescope has an 11 m diameter mirror. Which one has a greater light-gathering power?
Keck
SALT
They both gather the same amount of light.
A ground-based telescope to observe X rays would
be a powerful tool for studying abnormally cold stars or distant planets
give astronomers the chance to study the insides of stars and planets
be worthless because no astronomical objects emit X rays
be worthless because X rays cannot get through the Earth's atmosphere
