Ghostly remnants of a useless star captured in gorgeous picture

When a large star runs out of gas and involves the top of its life, it may explode in an unlimited and epic occasion referred to as a supernova, which could be as shiny as a whole galaxy. These explosions can obliterate something round them, however they aren’t merely damaging — they will additionally create gorgeous constructions referred to as supernova remnants. These remnants are shaped as shock waves from the explosion journey by close by clouds of gasoline, sculpting them into lovely shapes.

One such ghostly remnant has been captured by a ground-based instrument referred to as OmegaCAM on the European Southern Observatory’s VLT Survey Telescope.  The Vela supernova remnant is positioned 800 light-years away and was created by the dying of a star round 11,000 years in the past.

This image shows a spectacular view of the orange and pink clouds that make up what remains after the explosive death of a massive star — the Vela supernova remnant. This detailed image consists of 554 million pixels, and is a combined mosaic image of observations taken with the 268-million-pixel OmegaCAM camera at the VLT Survey Telescope, hosted at ESO’s Paranal Observatory. OmegaCAM can take images through several filters that each let the telescope see the light emitted in a distinct colour. To capture this image, four filters have been used, represented here by a combination of magenta, blue, green and red. The result is an extremely detailed and stunning view of both the gaseous filaments in the remnant and the foreground bright blue stars that add sparkle to the image.

When the large star died, it ejected its outer layers, which shaped the filament-like constructions seen within the picture. The dense core that remained grew to become a neutron star.

To seize this picture, which is a mosaic and has a complete of 554 million pixels, astronomers used the 268-million-pixel OmegaCAM with numerous filters to view totally different wavelengths of sunshine.

“OmegaCAM can take images through several filters that each let the telescope see the light emitted in a distinct color,” the European Southern Observatory explains. “To capture this image, four filters have been used, represented here by a combination of magenta, blue, green and red. The result is an extremely detailed and stunning view of both the gaseous filaments in the remnant and the foreground bright blue stars that add sparkle to the image.”
