- 1Why can we learn more about the universe as telescopes improve?Improves magnification, so we can see further into space
Improves detail and quality
Allows photos to be taken, so you can analysis over time and see the change - 2What is the most accepted theory?The Big Bang theory
- 3Note: Scientists have detected low frequency electromagnetic radiation coming from.........turn overOf the universe.....ooooooh
- 4What does cmb radiation stand for?Cosmic microwave background radiation
- 5What are the two theory's of how the universe was created called?The steady state theory and the big bang theory
- 6What is red shift?Light from distant galaxies are moving away from us, it supports the big band theory by showing the whole universe is expanding
- 7What are the TWO pieces of evidence for the Big Bang Theory,CMB radiation, and Red-shift
- 8What is the LIFE-CYCLE of a star1) stars form from clouds of gas called NEBULAS
2) the force of gravity pulls the cloud of dust together
3) due to a temperature increase, hydrogen nuclei join together to form helium nuclei........
A lot of energy is given out- A star is born!
4) Eventually, the hydrogen in the core begins to run out, forming a RED GIANT
5) lastly, the star become unstable, it throws out a layer of dust and gas , so this leaves behind a hot, dense solid core , which cools down to form a WHITE DWARF (that's me :0 how rude) - 9What is a spectrometer?A tool used to analyse the light given out by stars and galaxies
- 10What is the smallest planet (not including Pluto)Mercury
- 11What are the problems with using telescopes?Light pollution from streets lamps, Air pollution such as dust particles reflect and absorb light
- 12What do space landers do?Collect data about conditions ie.tempurature, take photos, collect soil/rocks
- 13What do scientists look for from outer space when searching for aliens?Radio signals
- 14What does SETI stand for?Search for ExtraTerrestrial Inteligence
- 15What is a galaxy?Group of stars
- 16What is the name of our galaxyThe Milky Way.....I'm hungry now! ;)
- 17Which planet is furthest away from the sun?Neptune
- 18What is the biggest planet?Jupiter
