|
electromagnectic spectrum
|
arrangement of electromagnetic waves according to their wave length
|
|
|
refracting telescope
|
uses convex lenses, which curve out, light goes through a convex objective lense and is bent to form an image at focal point
|
|
|
reflecting telescope
|
uses a curved mirror to direct light, light from object passes trough open end, which strikes a concave mirror
|
|
|
observatory
|
where optical telescopes used by professionals are stored
|
|
|
radio telescope
|
used to study radio waves travling through space
|
|
|
rocket
|
egines that have everything they need for the burning of fuel
|
|
|
satellite
|
any object that revolves around another object
|
|
|
orbit
|
curved path followed by a satellite as it revolves around an object
|
|
|
space probe
|
is an instrument that gathers information and sends it back to earth
|
|
|
project mercury
|
first project in U.S. program to reach the moon, it was to orbit a piloted spacecraft around earth and to bring it back safely
|
|
|
project Gemini
|
second project in U.S. program to reach the moon, they had to connect with another spacecraft in orbit and investigate the effects that space travel had on the human body
|
|
|
project Apollo
|
the final stage of the U.s program to reach the moon, apollo 11 was the first to land on the moon
|
|
|
space shuttle
|
reusable spacecraft that transports astronuats,satellites, amd other materials to and from space
|
|
|
space craft
|
has living quarters, work and excerise areas, and all the equipment and support systems needed for humans to live and work in space
|
|
|
electromagnetic waves carry energy through______ and______
|
space and matter
|
|
|
if there is no matter in space that means that sound waves _______?
|
cannot be transmitted
|
|
|
what is the sequence of the electromagnetic spectrum from smallest wave length to largest wave length
|
radio waves, microwaves,infrade,radiation,visable light,ultraviolet radiation, X rays, gamma rays
|
|
|
when and why was the hubble telescope placed in space
|
april 25, 1990 so scientists could avoid looking through our atmosphere
|
|
|
what happens in our atmosphere with some of the energy we receive from space?
|
it gets absorbed and distorted
|
|
|
what is the process to adjust distortion in images that go through our solar system
|
adaptive objects uses a laser to probe for atmospheric disturbance, the information is then fed into a computer so it can compensate for atmospheric conditions as it processes images made from space
|
|
|
what is the good thing about radio telescopes
|
radio waves pass freely through earth's atmosphere so it is useful under most weather conditions and at all times of day and night
|
|
|
how big is the largest radio telescope?
|
300 meters in diameter
|
|
|
what year did the apollo 11 land on the moon
|
july 20,1969
