Protostar - Wikipedia
A protostar is a very young star that is still gathering mass from its parent molecular cloud. It is the earliest phase in the process of stellar evolution. [1]
Protostar – Definition & Detailed Explanation - Sentinel Mission
What is a Protostar? A protostar is a stage in the formation of a star where a dense cloud of gas and dust begins to collapse under its own gravity. This collapse triggers the process of nuclear fusion, which eventually leads to the birth of a new star.
Protostar L1527 - ESA/Webb
The protostar L1527, shown in this image from the NASA/ESA/CSA James Webb Space Telescope, is embedded within a cloud of material that is feeding its growth. Material ejected from the star has cleared out cavities above and below it, whose boundaries glow orange and blue in this infrared view.
What Is a Protostar? The Earliest Stage of a Star
A protostar is what forms before nuclear fusion ignites a star. Learn how collapsing gas clouds give rise to new stars over millions of years.

Protostars - Harvard University
The image below shows a very young protostar, still deeply embedded in its dust cloud. The star itself is the bright red spot near the base of the dark region. The bright spots above the star and strange spikes are artifacts in the image. Getting pictures of these objects is hard, because they remain covered in dust.
What is a Protostar ? - Universe Guide
A Protostar is the first stage of a star’s life after an event of some form has caused a nebula of dust and cloud to collapse. It has not yet built enough mass to fuse hydrogen to helium.
Webb reveals protostar features within the dark cloud L1527
The James Webb Space Telescope of NASA has discovered new information about the dark cloud L1527 and its protostar. Only visible in infrared light, the nebula's brilliant hues demonstrate how the protostar is actively assembling material to develop into a fully formed star.
What is a Protostar? (with pictures) - AllTheScience
What is a Protostar? A protostar is a young star which is in the early stages of formation, before it reaches the main sequence stage. This stage of star formation can last 100,000 years or more, depending on the size of the star.
Glossary term: Protostar
Description: A protostar is an early stage in the star formation process. It is a large mass of gas and dust formed as a result of the contraction of a giant molecular cloud in the interstellar medium.
