What is formed from nebulae?
Stars, planets, and other celestial objects are formed from nebulae.
Stars and planetary systems are formed from nebulae.
Nebulae are vast clouds of dust and gas in space. They are often described as the birthplaces of stars and planetary systems. Within nebulae, a process called stellar formation occurs, leading to the creation of various celestial objects.
The primary objects formed from nebulae are stars. As gravitational forces cause the gas and dust to come together, they begin to collapse and form a dense core. This core continues to accumulate matter from the surrounding nebula, eventually becoming hot and dense enough to trigger nuclear fusion. At this point, a star is born, releasing energy and light.
Additionally, nebulae are also responsible for the formation of other objects like planets, asteroids, and comets. After star formation, leftover material in the nebulae, known as protoplanetary disks, clump together to form planetary systems. Over time, these clumps undergo further accretion and eventually become fully formed planets.
In summary, nebulae are the starting point for the creation of stars, planets, and other celestial bodies by the process of gravitational collapse, fusion, and accretion.
