The ejecta from an exploded star (IMAGE) KTH, Royal Institute of Technology Caption The 3D distribution of ejecta from supernova SNR 0540-69.3 is shown in individual colors. Oxygen can be seen in grey, and hydrogen appears in turquoise and red. The oxygen in the innermost region has been removed, so that only the outer ring is shown. A red circle is included for reference to guide the eye. The newly discovered hydrogen blob is seen to the lower left. Credit Josefin Larsson Usage Restrictions Credit must be given to the creator.
