NASA’s Hubble Captures Light Show Around Rapidly Dying Star
NASA’s Hubble Space Telescope reveals the clearest view yet of the Egg Nebula.

This stunning image from NASA’s Hubble Space Telescope reveals a dramatic interplay of light and shadow in the Egg Nebula, sculpted by freshly ejected stardust. Located approximately 1,000 light-years away in the constellation Cygnus, the Egg Nebula features a central star obscured by a dense cloud of dust — like a “yolk” nestled within a dark, opaque “egg white.” Only Hubble’s sharpness can unveil the intricate details that hint at the processes shaping this enigmatic structure.
It is the first, youngest, and closest pre-planetary nebula ever discovered. (A pre-planetary nebula is a precursor stage of a planetary nebula, which is a structure of gas and dust formed from the ejected layers of a dying, Sun-like star. The term is a misnomer, as planetary nebulae are not related to planets.)

The Egg Nebula offers a rare opportunity to test theories of late-stage stellar evolution. At this early phase, the nebula shines by reflecting light from its central star, which escapes through a polar “eye” in the surrounding dust. This light emerges from a dusty disk expelled from the star’s surface just a few hundred years ago.
Twin beams from the dying star illuminate fast-moving polar lobes that pierce a slower, older series of concentric arcs. Their shapes and motions suggest gravitational interactions with one or more hidden companion stars, all buried deep within the thick disk of stardust.
Stars like our Sun shed their outer layers as they exhaust their hydrogen and helium fuel. The exposed core becomes so hot that it ionizes surrounding gas, creating the glowing shells seen in planetary nebulae such as the Helix, Stingray, and Butterfly nebulae. However, the compact Egg Nebula is still in a brief transitional phase — known as the pre-planetary stage — that lasts only a few thousand years. This makes it an ideal time to study the ejection process while the forensic evidence remains fresh.
The symmetrical patterns captured by Hubble are too orderly to result from a violent explosion like a supernova. Instead, the arcs, lobes, and central dust cloud likely stem from a coordinated series of poorly understood sputtering events in the carbon-enriched core of the dying star. Aged stars like these forged and released the dust that eventually seeded future star systems, such as our own solar system, which coalesced into Earth and other rocky planets 4.5 billion years ago.
Hubble has turned its gaze towards the Egg Nebula before. A first visible-light image from the telescope’s WFPC2 (Wide Field and Planetary Camera 2) was complemented in 1997 by a near-infrared NICMOS (Near Infrared Camera and Multi-Object Spectrometer) image, giving a closer look at the light given off by the nebula. In 2003, Hubble’s ACS (Advanced Camera for Surveys) yielded a new view of the Egg, showing the full extent of the ripples of dust around it. A further image from WFC3 (Wide Field Camera 3) in 2012 zoomed in on the central dust cloud and dramatic gas outflows. This new image combines the data used to create the 2012 image with additional observations from the same program to deliver the clearest look yet at this intricate cosmic egg.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.
