Looking Into Space

Question 1

what do telescopes help you do

Answer 1

see distant objects clearly`

Question 2

what is a telescope called that detects visible light

Answer 2

an optical telescope

Question 3

what do telescopes use to allow you to see distant objects

Answer 3

refraction and reflection

Question 4

what are the two ways you can increase the quality of of the image you form when using a telescope

Answer 4

• increase the aperture of the telescope

- use a higher quality objective lens

Question 5

what is the aperture of a telescope

Answer 5

• the diameter of the objective lens

- the big lens at the end of the telescope where light from distant object enters

Question 6

why does the earths atmosphere get in the way of trying to detect light from space

Answer 6

the atmosphere absorbs a lot of the light coming from space before it can reach us

Question 7

what would you have to do to observe the frequencies of radiation absorbed by the atmosphere

Answer 7

go above it and into space

Question 8

what is light pollution and what does it do

Answer 8

• it is light thrown up into the sky from street lamps

- it makes it hard to pick out dim objects

Question 9

what is air pollution and what does it do

Answer 9

• pollution in the air

- it can reflect and absorb light coming from space

Question 10

how would you get the best view possible with a telescope from earth

Answer 10

• going to a place where theres less atmosphere above it, like the top of a mountain
• and going to a dark place away from cities

Question 11

what could optical telescopes look at

Answer 11

objects close by and in other galaxies

Question 12

why are other types of electromagnetic telescopes needed to observe some things in space

Answer 12

because not all objects in space emit visible light but hey emit other wavelengths of electromagnetic radiation

Question 13

what happened from the 1940s and onwards and what has that allowed us to do

Answer 13

• telescopes were developed for all parts of the EM spectrum

- allows us to observe parts if the universe we couldnt see before and learn more about it

Question 14

what are x ray telescopes good for

Answer 14

seeing violent and high temperature events in space, like an exploding star

Question 15

what telescopes were responsible for the discovery of the cosmic microwave background radiation

Answer 15

radio telescopes

Question 16

what have bigger telescopes given us and what is that effect

Answer 16

• they have given us better resolution and gather more light

- so we can see things that were previously too faint

Question 17

what has an improved magnification allowed us to do

Answer 17

• look further into space

- so more galaxies are being discovered

Question 18

what do modern telescopes work alongside and why

Answer 18

• computers
• because they help create clearer and sharper images
• which makes it easier to capture these images to be analysed later

Question 19

what have computers being used alongside telescopes allowed for

Answer 19

• the collection and storage of huge amounts of data ll day without having to rely on humans
• they also make it easier and quicker to analyse this data
