As we already know that stars die, but as they do so, they leave behind remnants, usually compact objects of some sort, like a white dwarf, neutron star or black hole. What kind of remnant it becomes depends on the initial mass of the star.

its ultraviolet radiation ionizes the inner parts of the surrounding cloud, producing a spectacular display called a Planetary Nebula. In addition, the core becomes the white dwarf shining only by the stored heat, not by nuclear reactions. This object has a white-hot surface when it first becomes visible, although it appears dim

The beautiful night sky is filled with thousands of stars that we can see and millions of which we cannot see, with about 4800 stars being born every second. These stars have a life cycle of about 40,000 years to about 10 billion years. However, all these billions of stars in the Universe are at a different point in their life cycle. In this topic, we will be discussing about how these stars are formed and how do they die.
