Hubble Captures Light Show Around Rapidly Dying Star
Hubble's images reveal the Egg Nebula’s dust ejection, disk gaps creating searchlight rays, and concentric rings linked to a binary companion, illuminating early post-AGB star evolution.
- At roughly 3,000 light-years, the Hubble Space Telescope recently produced the most comprehensive images of the Egg Nebula, a preplanetary nebula around a post-AGB star.
- As a rare, short-lived phase, the preplanetary nebula stage sits between the AGB and planetary nebula phases and was renamed from protoplanetary to avoid confusion; the Egg Nebula is the first, youngest, and closest known preplanetary nebula.
- Hubble resolved three components: concentric rings, dual searchlight-like rays, and an obscured central region, with ejecta speeds around 18 km/s and 100 km/s indicating different wind phases.
- The observations validated the central dust model and strengthen Hubble Space Telescope's role as an Egg Nebula laboratory to refine Sun-like star evolution models.
- Over the next centuries, V1610 Cygni, which left the AGB recently, will heat and ionize ejecta, with a post-AGB lifetime of about 1,000 years.

Hubble Space Telescope captures the stunning final breaths of a dying star
It's the final act for a star in the constellation Cygnus, some 1,000 light-years away. But it's not dying without one final show — and NASA's Hubble Space Telescope has captured it in astonishing detail.

Hubble's latest image unveils the Egg Nebula in unprecedented detail. This pre-planetary nebula, formed by a dying Sun-like star, shows dramatic light beams piercing dust to illuminate gas shells and hints at our own Sun's distant future.
Last gasps of dying Sun-like star captured by Hubble
One of the most important lessons we learn from studying the Universe is that none of the sources of light that we see — none of the stars, galaxies, stellar remnants, quasars, or heated matter — will continue to shine forever. After a finite amount of time, anything powered by nuclear fusion or infalling matter will run out of fuel. Anything that emits light because it’s hot will cool, and once it’s cooled enough, it won’t emit detectable light…
Hubble captures light show around rapidly dying star
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 …
