Khi nao dung Protoplanetary Disk 3D Explorer

Use this explorer when you want to see the real measured structure of a planet-forming disk, and skip it when you want a general planet-formation overview or the finished solar system.

• Showing where ALMA measured bright rings and dark gaps around HL Tau
• Explaining the leading interpretation that young planets are clearing each gap
• Comparing gap distances out to the edge of the measured disk, about 97 AU

This is an educational visualization with illustrative brightness and sped-up motion; the ring and gap distances are the real ALMA measurements.

Walk the controls in the step-by-step guide, or compare options in vs alternatives. Open the Protoplanetary Disk 3D Explorer.
