Protoplanetary Disk Formation - How Planets Begin to Form #115344 (License: Personal Use)

This image depicts a protoplanetary disk-a rotating circumstellar disk of dense gas and dust surrounding a newly formed star. The central bright region represents the young star, while the reddish inner ring and bluish outer halo illustrate temperature gradients and material distribution critical for planet formation. Such disks are the birthplaces of planetary systems, including our own Solar System.

Used on astronomy education pages, NASA or ESA outreach sites, and science blogs explaining star and planet formation; targets users seeking visual understanding of early solar system development.
