Observing Universe
lunar refers to...
anything released from the moon
Cool stars emit what length waves with what type of energy (high/low)
long, low energy waves
Scientist assume that extraterrestrial would need similar needs as humans to survive such as________, ________and _________.
water, organic molecules, source of energy.
What is a limit of using radio telescopes
Revise this statement. It takes billions of year for all light from outer space to reach earth
It takes billions of year for light from stars to reach earth
Hot stars emit what length waves with what type of energy (high/low)
shorter, higher energy waves
What types of wavelengths can pass through earth's atmosphere?
Visible light wavelengths, microwaves and radio waves can pass through Earth’s atmosphere where other types of electromagnetic waves do not.
Do refracting telescopes use lenses or mirrors to focus light
lenses
true of false: Is the international space station (ISS) and example of a satellite?
True
what type of energy is transferred through EM waves
radiant energy
What types of wavelengths can space-based telescopes collect
Space based telescopes can collect energy at all wavelengths including infrared light ultraviolet light, and x-rays.
True or false: reflecting telescopes use lenses to collect and focus light
false, they use mirrors
In what year did America travel to the moon; what was the name of the space mission?
1969; Apollo
Stars emit energy that radiates into space as what types of waves
EM waves (electromagnetic)
The small icy dwarf planet observed orbiting the sun is ________
Pluto
What is a space probe; and how are landers different from a flybys?
An uncrewed spacecraft sent from earth to explore objects in space that work automatically or by remote. Touch down on surface and release rovers vs orbit or land
What affect has space exploration played on Florida?
Space coast, jobs, Kennedy space center, tourism just to name a few!
What are the shortest and longest EM waves
radio & micro =longest
uv & gamma=shortest
What do scientists learn from studying wavelengths of stars
By utilizing different wavelengths, scientists assemble a full portrait of stars, learning more about their temperatures, what they are made of, activities and processes happening in them, what color they are, how much light they are emitting
Compare a satellite to an artificial satellite.
