The bright star at the center of NGC 3132, while prominent when viewed by NASA’s Webb Telescope in near-infrared light, plays a supporting role in sculpting the surrounding nebula. A second star, barely visible at lower left along one of the bright star’s diffraction spikes, is the nebula’s source. It has ejected at least eight layers of gas and dust over thousands of years.
But the bright central star visible here has helped “stir” the pot, changing the shape of this planetary nebula’s highly intricate rings by creating turbulence. The pair of stars are locked in a tight orbit, which leads the dimmer star to spray ejected material in a range of directions as they orbit one another, resulting in these jagged rings.
Hundreds of straight, brightly-lit lines pierce through the rings of gas and dust. These “spotlights” emanate from the bright star and stream through holes in the nebula like sunlight through gaps in a cloud.
But not all of the starlight can escape. The density of the central region, set off in teal, is reflected by how transparent or opaque it is. Areas that are a deeper teal indicate that the gas and dust are denser – and light is unable to break free.
Data from Webb’s Near-Infrared Camera (NIRCam) were used to make this extremely detailed image. It is teeming with scientific information – and research will begin following its release.
This is not only a crisp image of a planetary nebula – it also shows us objects in the vast distances of space behind it. The transparent red sections of the planetary nebula – and all the areas outside it – are filled with distant galaxies.
Look for the bright angled line at the upper left. It is not starlight – it is a faraway galaxy seen edge-on. Distant spirals, of many shapes and colors, also dot the scene. Those that are farthest away – or very dusty – are small and red.

Public domain masterpieces
The mission of this series is to promote space and science. The creators want these designs to hang on your wall, which is in line with our mission in Astrography. That is why we decided to use our competence in printing cosmos inspired graphics and photos to provide you with these projects in the highest possible quality on Fine Art (Giclée) pigments and papers.
These projects are available in the public domain. You can download them from NASA website and print them at any printing house. but we are convinced that thanks to our experience in printing space photographs we are able to provide the best quality of these posters in the world. We do not earn on copyright here. In this series, we provide specializing printing competences & technologies (dedicated in space), packaging and worldwide logistics. Let the promotion of science and art become a common fashion.
Posters will look great in your home, children’s room, or office.
