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.
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.
Stars - NASA Science
At first, most of the protostar’s energy comes from heat released by its initial collapse. After millions of years, immense pressures and temperatures in the star’s core squeeze the nuclei of hydrogen atoms together to form helium, a process called nuclear fusion.
Protostar - Las Cumbres Observatory
A protostar looks like a star but its core is not yet hot enough for fusion to take place. The luminosity comes exclusively from the heating of the protostar as it contracts.
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.
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 – Mass Formed Because of Contraction of Gas
You can think of a protostar as an immature star, starting its stellar (pertaining to stars) evolution. The development of a star begins with the nebula, a swirling cloud of interstellar (in between starts) gas and dust molecules.

40 Facts About Protostar
What is a protostar? A protostar is the earliest stage in the formation of a star. Imagine a giant cloud of gas and dust in space. Over time, gravity pulls this material together, causing it to collapse and heat up. This hot, dense core is what we call a protostar.
