Iron in the Butterfly Nebula
The Butterfly Nebula, NGC 6302, spans over three light-years and has a central star with an estimated surface temperature exceeding 200,000 degrees Celsius. This dying star, though exceptionally hot, is hidden from direct view by a dense torus of dust. The Hubble Space Telescope captured this sharp close-up, revealing the nebula's intricate structure.
