The formation of new stars is closely related to supernovae and planetary nebulae, as both phenomena contribute to the recycling of stellar material. When a massive star explodes in a supernova, it disperses heavy elements and gas into space, enriching the interstellar medium and providing the raw materials for new star formation. Similarly, the outer layers of a dying star can be expelled as a planetary nebula, also contributing gas and dust to the surrounding region. These processes create regions of higher density that can collapse under gravity, leading to the birth of new stars.
The formation of new stars can be triggered by the shock waves and turbulence generated by supernovas, which compress gas and dust, leading to new star formation. Planetary nebulae are formed from the outer layers of certain types of stars when they reach the end of their life cycle. These nebulae can enrich the surrounding interstellar medium with elements necessary for forming new stars.
Solar systems are formed by nebulae. The larger pieces of dust and other materials attract the smaller ones, get bigger, and attract even more pieces of random things, and so on, until a star and sometimes planets are eventually formed.
People who study planets and other celestial bodies are called planetary scientists or astronomers. Planetary scientists often focus on the formation, composition, and processes of planets, moons, and other objects in the solar system and beyond. They may also engage in research related to astrobiology and the potential for life on other planets. Astronomers, in a broader sense, study celestial phenomena, including stars, galaxies, and the universe as a whole.

A Planetary Nebula. See related question.
Both galaxies and nebulae are large clouds of gas and dust in space. They can both contain regions of star formation and have unique shapes and structures. Additionally, they both play important roles in the formation and evolution of stars and planetary systems.

A planetary nebula forms after a main sequence star casts off its outer layers. The ejected gas and dust create a beautiful glowing shell of ionized gas that surrounds the remaining hot core of the star, known as a white dwarf.
A supernova will create the pulsar.See related question.
No. Supernovas are cataclysmic eruptions from massive stars that have come to the end of their lives. See related questions

Nebulae are large clouds of dust and gas in space where stars are born. Within a nebula, gravitational forces can cause the gas and dust to collapse and form a protostar, which eventually ignites nuclear fusion and becomes a star. Therefore, nebulae are the birthplaces of stars, and stars are formed from the material within nebulae.
The Cats's Eye Nebula is a perfect example of a planetary nebula. See related link for a pictorial.
Some examples of different nebulae include the Orion Nebula, the Crab Nebula, the Eagle Nebula, and the Helix Nebula. These nebulae vary in size, shape, and composition, but they are all vast clouds of dust, gas, and plasma in space.
Mars was created when the other planets were, around 4.6 billion years ago during the formation of our solar system in a process known as planetary accretion. Please see the related links.
