Science 2 Flashcards
(21 cards)
Gathers and focus light
Telescopes
What is the electromagnetic spectrum
Radio waves, microwaves, infrared radiation, visible light, ultraviolet rays, X-rays and gamma rays
We can only see visible light, stars emit all wavelengths
What is the Scientific notation
Bigger the exponent, bigger the number
Distance=time
What does this mean
Light travels fast, but space is big
and 300,000 km/s
What are some examples of Earth based telescopes
Optical and radio
What causes Atmospheric distortion and interference
moisture
What is an Advantage of space telescopes
No atmospheric interference, all wavelengths
What is the Difference between: Rockets, probes and satellites
Satellites orbit space and use navigation/GPS, telecommunication, and weather/climate, while Probes gather data by exploring objects in space and have four space crafts the flyby, lander, orbiter, and the rover, last but not least the rockets are designed to send themselves into space leaving behind gas from one end.
What Exoplanets and life in the universe
Requirements –
How do we find them –
Requirements for life - water
How do we find them - see, wobble, transit/Using astrometry, exoplanets can be found by measuring tiny changes in the star’s position as it wobbles around its centre of mass
CADRE
(current)
- They are three rovers
- They will travel the moon and record every inch so when they get home they can put in 3D
- They will also make note of what part of the moon is too dangerous for the astronauts to go to

THE ROMAN CORONAGRAPH INSTRUMENT
(future)
- Built to block the glare if stars and image the planets and disks in orbits around them
- It will fly above WFIRST
- It will make stars 100 times fainter
