Stars are born from clouds of gas and dust that collapse under their own gravitational pull. When the cloud collapses, a dense, hot core forms and begins to collect dust and gas, creating an object called a “protostar”.

This Hubble infrared image captures a protostar named J1672835.29-763111.64 in the reflection nebula IC 2631, which is part of the star-forming region Chamaeleon in the southern constellation Chamaeleon. Protostars glow with the thermal energy released by the clouds contracting around them and the accumulation of material from the nearby gas and dust. Eventually enough material will collect, and the core of a protostar will become hot and dense enough for nuclear fusion to begin, and the transformation into a star will be complete. The leftover gas and dust can become planets, asteroids, comets, or remain as dust.

This image is part of a Hubble survey that targets 312 protostars in molecular clouds previously identified using the Spitzer and Herschel infrared space observatories. Protostars are mainly visible in infrared light because they give off a lot of thermal energy and their visible light is obscured by the dust around them. Hubble’s advanced infrared capabilities could better resolve the protostars and study their structure, including the accumulation of gas and dust and faint companion objects.
