-
Refracting telescope
A telescope that uses a lens to capture light
-
Satellite
A piece of equipment that orbits earth
-
Orbiters
A piece of equipment that orbits a planet and sends data back to earth
-
Solar Nebula Theory
A theory of how stars are formed that states a star is formed from clouds of hydrogen and dust in a nebula
-
Nebula
A cloud of dust and gas in space
-
Protostar
A new star, a disc shaped cloud of dust and gas
-
Nuclear Fusion
When it is so hot that when atoms hit each other the become other atoms
-
Photosphere
The surface of the sun
-
Sunspot
A darker, cooler area on the suns photosphere
-
Solar Wind
Wind created by the suns gravity
-
Solar Flare
A discharge of charged particles from the suns photosphere (Northern Lights)
-
Importance of the sun
The sun is what our planet revolves around
-
Luminosity
A stars brightness
-
Absolute Magnitude
A stars brightness at a distance of 32.6 light years away
-
Spectroscope
An instrument that allows you to see the spectrum given off by light, indicating what elements can be found there.
-
Spectral lines
Distinct lines that help to define what atoms and molecules are within that spectrum.
-
H-R Diagram
A way of graphing a stars spectrum type against its luminosity
-
Main Sequence
Where a star stays for most of its life before evolving and dying, either a low, intermediate or high mass star.
-
White Dwarf
The stage where a star slowly cools down and fades away
-
Supernova
When a star explodes at the end of its life
-
Neutron Star
A star created by a supernova that is so hot only protons and electrons essentially melt themselves into neutrons
-
How low mass stars evolve
Gravity compresses into white dwarfs and eventually fade away
-
Black hole
a patch of space that has mass but no volume
-
How do intermediate mass stars evolve
They become red giants that eventually explode in a super nova and remain as nebula
-
Evolution of high mass stars
High mass stars become red supergiants before either condensing into a neutron star or exploding into a black hole
