NGC 2438 is a planetary nebula, formed after the death of a Sun-like star.

The medium-sized star would have expelled its outer layers of gas into space as it died, leaving behind a white-dwarf core.

A halo of glowing gas over 4.5 light-years across surrounds the nebula’s brighter inner ring.

Many round or nearly round planetary nebulae display these halo structures, and astronomers have been investigating how they evolve.

NGC 2438 was one of the nebulae studied, and researchers found that the nebula’s halo glows due to the ionizing radiation of the central white dwarf.

The colorful planetary nebula, NGC 2438, appears to lie on the outskirts of the open star cluster, M46 (NGC 2437). The nebula is actually in the foreground between us and the star cluster.

NGC 2438 is a planetary nebula which is located at about 3,000 light-years from Earth in the constellation of Puppis.

Planetary nebulae like this one are formed when a sun-like star progresses from main-sequence, where it spends most of its stellar life in, before blooming into a red-giant, ultimately shedding its outer layer of gases off into space, forming a nebula.

Distance estimates also place NGC 2438 closer than M46 and so the nebula appears in the foreground of the young star cluster.

NGC 2438’s aurora of glowing gas extends to an astonishing distance of 4.5 light-years in across.
