A large cloud of dust and gas in space from which a star can form.
Used by AQA, Edexcel and OCR
Specification 4.8.1.1, 4.8.1.2 · Paper 2
Revise: Our solar systemLike other stars, it began forming from a nebula: a cloud of dust and gas in space. The particles in this cloud had mass, so gravitational attraction acted between them.
A cloud of gas and dust in space from which a star can form.
Specification 7.16P, 7.18P · Paper 1
A large cloud of gas and dust in space from which stars can form.
Revise: Star Evolution (Solar Mass)A star begins within a nebula, a huge cloud containing gas and dust. Gravity pulls some of this material together. As more matter gathers, the central region becomes denser and hotter.
A large cloud of gas and dust from which stars can form.
Specification P8.3c · Paper 2 (Foundation), Paper 4 (Higher)
A cloud of gas and dust in space from which a star can form.
Revise: Lifecycle of a starLike other stars, it began in a cloud of gas and dust called a nebula. Gravity pulled some of this material together. As more material gathered, its gravity drew in still more, forming a dense, contracting protostar.
Paper 1, Paper 2
A cloud of gas and dust in space from which stars and planetary systems can form.
Use the word “nebula” for the original cloud of dust and gas; do not confuse it with a galaxy or solar system.
Use the exact order required by the specification: nebula → main-sequence star → red giant → white dwarf.
