Kepler's 2nd Law deals with
the shape of the planets' orbits
the area the planet travels

Why would we put a telescope in space?
Because the Earth's atmosphere makes the pictures blurry
Because it's dangerous to keep telescopes on Earth
They have better resolution when they are closer to the stars
So that scientists from around the world can share them more easily
A spectroscope allows us to investigate which 2 things:
The elements that make up stars
The motion of objects in space
The age of objects in space
Whether life exists on other planets
(a) are used to take samples and investigate distant objects that we cannot travel to.

What is white light?
The absence of color
All colors combined
A really bright light
Artificial, has to be made by humans
Satellites use what kind of waves to communicate with Earth?
They send out mechanical waves using high pitch sound.
They code information with different wavelengths of electromagnetic waves.
They flash messages in light, using morse code
They don't, we have to take them down & read their microchips
What's the big difference between a satellite and a space probe?
Satellites can't orbit without being remote controlled, space probes can function on their own.
Satellites can go farther than space probes
Neither requires a human on board to investigate space
Satellites are generally for localized data collection, and space probes are physically sent deep into space to collect data.
