Eta Carinae: 2D Images to 3D Models

Component January 25th, 2022

This visualization showcases the multiwavelength emissions and three-dimensional structures surrounding Eta Carinae, one of the most massive and eruptive star systems in our galaxy.

Two of NASA’s Great Observatories, the Hubble Space Telescope and the Chandra X-ray Observatory, have observed Eta Carinae using visible, ultraviolet, and x-ray light, as well as in the Hydrogen alpha emission line. These 2D portraits have been modeled by astronomers and artists to create a 3D visualization that brings the telescope images to life.

The sequence presents the layered model one wavelength region at a time, and builds up the complex nested structure. The viewer gets a full 360-degree view and can assemble a complete mental model that aids interpretation of the NASA observations.
