life cycle
The life cycle of a star is very similar to the life cycle of humans, we are born, toddlers teenagers, middle aged, old aged and then we die.
The first stage of a stars life is the nebula (a cloud of dust and gas).Clumps and gas then form to be called protostars. When the core of a protostar reaches a certain temperature, nuclear fusion happens. When it starts to shine it means that the star has been born.
A star is a super-hot ball of gas with a core where hydrogen is fusing into helium. When all the hydrogen is gone, helium is then fused into carbon. To be equilibrium is the life goal of a star. To be an equilibrium means that the balance between gravity and it causing atoms to move towards to the centre, and pressure moving heat and light from the centre.

black holes
Black holes are places where gravity has become so extreme that I over takes all other forces in the universe. The strength of the gravity stops anything from escaping, even light. The Universe has so many black holes that it is impossible to count them all, however, soon the slowly return their power to the universe by evaporating. They need to have a great amount of mass in a small amount of space. This means that they don’t have to be very big just the compact has to be large. Every single black hole is exactly the same, expect for the mass, the way they spin and their electric power. If in fact there was something in the black hole it would be impossible or it to escape, therefor it would be impossible to know if there was something inside.
