1. Dwarf stars: These are the most common type of stars and they are relatively small and dim compared to other star types. Examples include red dwarfs (M-type stars) and brown dwarfs (not technically stars, but star-like objects that are too small to sustain nuclear fusion).
2. Giant stars: These stars are much larger and brighter than dwarf stars. They have exhausted their nuclear fuel and expanded in size. Examples include red giants, blue giants, and yellow giants.
3. Supergiants: These are even larger and more massive than giant stars. They are extremely bright and can be found in various colors, including red, yellow, and blue. Examples include red supergiants like Betelgeuse and blue supergiants like Rigel.
4. White dwarfs: These are the remnants of stars that have exhausted their nuclear fuel. They are very dense and compact, similar in size to Earth but with much greater mass. They emit a faint white glow as they cool down over billions of years.
5. Neutron stars: These are incredibly dense and compact stars that are formed from the remnants of massive stars after a supernova explosion. They are composed almost entirely of neutrons and are only a few kilometers in diameter. They have extremely strong magnetic fields and can rotate rapidly, emitting beams of radiation that create pulsar phenomena.
6. Black holes: These are the most extreme objects in the universe. They are formed from the remnants of massive stars that have undergone a supernova explosion and collapsed under their own gravity. They have an immense gravitational pull that nothing, not even light, can escape from within a certain radius called the event horizon. They are characterized by their singularity, a point of infinite density at their core.
