A contracting cloud of gas and dust with enough mass to form a star is called a molecular cloud or stellar nursery. Within these clouds, regions of higher density can collapse under their own gravity, leading to the formation of protostars. As the protostar accumulates mass and temperature increases, nuclear fusion eventually begins, marking the birth of a new star.
The gases and dust from which stars condense are called cosmic dust or particles.
It is sometimes called the Solar nebula.
The ash cloud of a volcano is called a volcanic plume or eruption cloud. It consists of ash, gases, and steam that are emitted during a volcanic eruption and can travel long distances depending on wind conditions.
The Nebular Hypothesis.
A nebula is a large cloud of gas and dust in space. As gravity pulls the particles in a nebula closer together, it can cause the material to condense and become concentrated enough to form a star and, eventually, planets.
A nebula
a protostar
it's a protostar
space cloud
It is usually just called a debris cloud or dust whirl.
a dust cloud
A star that begins as a large cloud of dust and gas is called a protostar. It forms as gravity causes the dust and gas to clump together and initiate the process of nuclear fusion in its core.
The gases and dust from which stars condense are called cosmic dust or particles.
A large cloud of gas and dust in space is called a nebula. These nebulae are often the birthplaces of stars and planets, with various types such as emission, reflection, and dark nebulae.
