Can a star turn into a planet?

Yes, a star can turn into a planet, but this transformation only happens for a very particular type of star known as a brown dwarf. Some scientists do not consider brown dwarfs to be true stars because they do not have enough mass to ignite the nuclear fusion of ordinary hydrogen.

What happens when a star starts producing iron?

Stars that have earned the title of "supergiant" are so massive and so hot that they begin fusing silicon to a solid core of iron. Once the star starts fusing iron, that's it? it's doomed. Fusing silicon to iron takes more energy than it gives off. Is there a black hole in Milky Way? The supermassive black hole at the center of our Milky Way galaxy is leaking. The Milky Way's central black hole, known as Sagittarius A* (Sgr A*), has been "leaking" or emitting jet-like superheated beams for several thousand years.

Why do stars twinkle?

As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle. Why do stars explode? But as a star burns through its fuel and begins to cool, the outward forces of pressure drop. When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion we call a supernova.

Moreover, how long do stars live for?

A star like our sun lives for about 10 billion years, while a star which weighs 20 times as much lives only 10 million years, about a thousandth as long. Stars begin their lives as dense clouds of gas and dust. How hot is a yellow star? 6000 K Color and Temperature Table 1.
