definitions
solar system
the Sun, the planets + their moons
part of Milky Way galaxy
galaxy
collection of stars
Universe
made of of all the galaxies
relative distances
1. moon=closest
2. Sun
3. planets
4. stars
5. other galaxies=furthest
relative sizes
1. moon=smallest
2. Earth
3. planets
4. Sun&stars
5. galaxies
6. Universe=biggest
P1.13 Exploring the Universe
electromagnetic radiation telescopes
show things visible light can't detect
modern telescopes
improved magnification
see far away galaxies
photography
gather more data
made with greater precision
clearer images
electromagnetic telescopes
see objects that can't been seen using visible light
telescope location
in space
microwaves
infrared
UV
gamma
Xrays
some visible light
dust, water vapour, pollution can distort image
on earth
visible light
radio waves
P1.14 Alien Life?
signs of life
liquid water
oxygen
from photosynthesising plants
chemical changes
e.g. methane
methods
space probes
soil experiment by landers/rovers
SETI
Search for Extraterrestrial Intelligence
P1.15 Life Cycles of Stars
left hand path
stars similar size to our Sun
right hand path
stars bigger than Sun
massive stars
gravity
pulls a nebula together
the hydrogen gets hot as GPE converted to thermal
pulls collapsed red giant together
forming white drwarf
P1.16 Theories about the Universe
steady state
universe has always existed
it is expanding
new matter is being created
big bang
whole universe started as a tiny particle 13.5billion ys ago
universe expanding from this+is still expanding
evidence
cosmic microwave background (CMB) radiation
microwave radiation originally from big bang
red shift
object moving away has increased wavelength+decreased freq
black lines 'shifted' to red end of spectrum
P1.17 Red-Shift
stars
the more distant the star-greater the red shift
sun is closer
distant star
theories
proves universe is expanding
supports both theories
but BB is accepted due to CMB radiation
