---|---|---|---|---|---|
Emission Nebula | Large clouds of gas and dust. Rich in hydrogen. Stars are born here
🗑
|
||||
Protostar | Large cloud of gas and dust that is contracting due to gravity. Could ignite to form a star.
🗑
|
||||
Nuclear fusion | The combining of atoms in the core of a star to create heavier atoms.
🗑
|
||||
Hydrostatic equilibrium | The balance of forces in a star. Gravity pulling in and nuclear fusion pushing out.
🗑
|
||||
Main sequence | Most stars live here for most of their life as they fuse Hydrogen atoms into helium atoms.
🗑
|
||||
Giant | Stage of stellar evolution when hydrostatic equilibrium becomes unbalanced and a main sequence star goes.
🗑
|
||||
Dwarf | Low mass,low luminosity, small star
🗑
|
||||
Supernova | Extremely massive stars explode
🗑
|
||||
Neutron star | Born from a supernova, small core (size of city) has so much gravity that protons and electron and crushed into neutrons.
🗑
|
||||
Black hole | Born from supernova. Core of a massive star collapse upon itself. Matter and light are pulled into a tiny space due to gravity.
🗑
|
||||
Planetary Nebula | Small dying stars shed their outer layers, leaving their core behind.
🗑
