Protostar - Definition & Detailed Explanation - Astronomical Objects ...
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.
NASA’s Webb Catches Fiery Hourglass as New Star Forms
Shocks and turbulence inhibit the formation of new stars, which would otherwise form all throughout the cloud. As a result, the protostar dominates the space, taking much of the material for itself. Despite the chaos that L1527 causes, it’s only about 100,000 years old – a relatively young body.

L1527 and Protostar (NIRCam Image) - Science@NASA
This 3D visualization exposes the structures around the protostar L1527 IRS. Even with the best optical telescopes, the nebula L1527 appears as a dark, featureless cloud.
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.

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.
