In Euclid’s wide, near-infrared, and visible light view, the arcs and filaments of the nebula’s bright central region are situated within a halo of colorful fragments of gas zooming away from the star. This ring was ejected from the star at an earlier stage, before the main nebula at the center formed. Hubble captures the very core of the billowing gas with high-resolution visible-light images, adding extra detail in the center of this image. The whole nebula stands out against a backdrop teeming with distant galaxies, demonstrating how local astrophysical beauty and the farthest reaches of the cosmos can be seen together in modern astronomical surveys. Together, these missions provide a rich and complementary view of NGC 6543 — revealing the delicate interplay between stellar end-of-life processes and the vast cosmic tapestry beyond.

A brain-new image from Webb! What looks like a brain (complete with what appear as left and right hemispheres) is actually a dying star blowing off a shell of gas, and within that shell, a cloud of various gases.

NASA’s Hubble Space Telescope reveals the clearest view yet of the Egg Nebula. This structure of gas and dust was created by a dying, Sun-like star. These newest observations were taken with Hubble’s Wide Field Camera 3.

This NASA/ESA Hubble Space Telescope image of NGC 7722, a lenticular galaxy located about 187 million light-years away, features concentric rings of dust and gas that appear to swirl around its bright nucleus.

A new image from NASA’s James Webb Space Telescope of a portion of the Helix Nebula highlights comet-like knots, fierce stellar winds, and layers of gas shed off by a dying star interacting with its surrounding environment. Webb’s image also shows the stark transition between the hottest gas to the coolest gas as the shell expands out from the central white dwarf.

NASA’s James Webb Space Telescope’s 2024 NIRCam image shows protostar EC 53 circled. Researchers using new data from Webb’s MIRI proved that crystalline silicates form in the hottest part of the disk of gas and dust surrounding the star — and may be shot to the system’s edges.

NASA’s SPHEREx Observatory has mapped the entire sky in 102 infrared colors, as seen here in this image released on Dec. 18, 2025. This image features a selection of colors emitted primarily by stars (blue, green, and white), hot hydrogen gas (blue), and cosmic dust (red).

The Calabash Nebula, pictured here — which has the technical name OH 231.8+04.2 — is a spectacular example of the death of a low-mass star like the Sun. This image taken by the NASA/ESA Hubble Space Telescope shows the star going through a rapid transformation from a red giant to a planetary nebula, during which it blows its outer layers of gas and dust out into the surrounding space. The recently ejected material is spat out in opposite directions with immense speed — the gas shown in yellow is moving close to a million kilometres an hour. Astronomers rarely capture a star in this phase of its evolution because it occurs within the blink of an eye — in astronomical terms. Over the next thousand years the nebula is expected to evolve into a fully fledged planetary nebula. The nebula is also known as the Rotten Egg Nebula because it contains a lot of sulphur, an element that, when combined with other elements, smells like a rotten egg — but luckily, it resides over 5000 light-years away in the constellation of Puppis (The Poop deck).
