A newly formed star is called a protostar. This is the early stage of a star's life cycle when it is still accumulating mass from its surrounding gas and dust. Once a protostar reaches a critical mass and temperature, nuclear fusion begins and it becomes a fully-fledged star.
A Main Sequence star.
Star matter is recycled through various processes such as supernova explosions, where heavier elements are formed and released back into space, eventually becoming part of new stars, planets, and other celestial bodies. This recycling of star matter is essential for the creation of diverse elements and the continuation of the universe's evolution.
Nebulae (gas and dust) protostar (formed by immense pressure in nebulae) ^ becomes either a Brown dwarf (basicall dead :P) or a Main sequence star which becomes: A Red giant (when MSS runs out f hydrogen ) if red giant is small it becomes a white dwarf and does nothing or a planetary nebulae if it's a big one it either becomes a Neutron star or a Black hole
after a nova star becomes bright it turns into a dwarf and explodes.

The line means: before it becomes fully daylight.
A neutron star.
Once a star explodes, it's no longer a star. The explosion itself is referred to as a "Super Nova."
a black hole
A star is created once enough dust/gas gather up (called nebulae) and the gravity from a nearby star or shockwave from a nearby supernova causes it to contract. Once a star dies, it blows and becomes a nebulae again, recreating the entire process over and over again to repeat until the end of time. (unless the star becomes a black hole.)
The elements in your body were once part of a star - billions and billions of years ago! Earth and everything on it was formed in space from bits and pieces of "star stuff."
The actual FIRST STAR is impossible to say when it existed. In the normal evolution of a star it becomes a protostar first. The life of a protostar is about 150,000 years before it becomes a main sequence star. But in the Early universe it is hard to say what was happening. They could have formed in days weeks months or even hours.
