Huge waves are sculpted in this two-lobed nebula called the Red Spider Nebula, located some 3,000 light-years away in the constellation of Sagittarius. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion kilometers (62.4 billion miles) high. The waves are caused by supersonic shocks, formed when the local gas is compressed and heated in front of the rapidly expanding lobes. The atoms caught in the shock emit the spectacular radiation seen in this image.

You may have already seen this several times before since it has already been very well processed by others so I felt there was little for me to contribute. At this point I've done so many planetary nebulas that I feel the need to do them all just to have a complete collection.
I spent many moments simply gazing into the center and contemplating its structure. The processing is slightly deceptive in that area. The center has been considerably darkened to allow for structural details to not be blown out. I didn't think I was going to do it when I started with this but I ended up trying it just to see how I'd do and ended up keeping it. That center blob which appears slightly greenish is actually a cloud in front of a very bright star. It's exactly as if you were looking up at our own sun with a small cloud just occluding it, which is to say it won't immediately burn your retinas but it's still unbearably bright.

The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888 as a new version of John Herschel's General Catalogue of Nebulae and Clusters of Stars. The NGC contains 7,840 objects, known as the NGC objects. It is one of the largest comprehensive catalogues, as it includes all types of deep space objects and is not confined to, for example, galaxies. Dreyer also published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues, describing a further 5,386 astronomical objects.

Hubble (2001-07-24) NGC 6537, Red Spider Nebula (Hubble) - The Red Spider Nebula, surfing in Sagittarius - not for the faint-hearted!
NGC6537 ou nebulosa da aranha vermelha é uma nebulosa planetária localizada a cerca de 4.000 anos-luz da Terra na constelação de Sagitário, próximo à direção do centro galáctico e com bastante h-alpha próximo à ela. A NGC6537 é uma nebulosa planetária bipolar com uma aparência lembra um X ou uma aranha com pernas flamejantes, formada por uma estrela em seus momentos finais. Seu núcleo é uma das estrelas centrais mais quentes conhecidas em nebulosas planetárias, com temperatura superior a 500.000 K, o que contribui para a intensa iluminação do material ao redor.
NGC 6537, or the Red Spider Nebula, is a planetary nebula located about 4,000 light-years from Earth in the constellation Sagittarius, near the direction of the galactic center and surrounded by strong H-alpha emission. NGC 6537 is a bipolar planetary nebula with an appearance that resembles an "X" or a spider with flaming legs, formed by a dying star in its final stages. Its core is one of the hottest known central stars among planetary nebulae, with a temperature exceeding 500,000 K, contributing to the intense illumination of the surrounding material.
