Helix Nebula
Helix Nebula (NGC 7293), optical image. This is a planetary nebula, a series of shells of gas cast off by a dying star. The ejection of the stars outer layers exposes its hot core, whose radiation ionises the shells, causing them to glow. The Helix Nebula is 650 light years from Earth, in the constellation of Aquarius. This image includes filters for the light from hydrogen (H-alpha), oxygen (OIII) and sulphur (SII) ions

EDITORS COMMENTS
This print showcases the mesmerizing Helix Nebula (NGC 7293), a celestial wonder located approximately 650 light years away from Earth in the constellation of Aquarius. This planetary nebula is formed by the intricate layers of gas expelled by a dying star, revealing its scorching core that emits radiation and ionizes these shells, causing them to emit an ethereal glow. The image beautifully captures the essence of this astronomical marvel through filters designed to capture specific wavelengths of light emitted by hydrogen (H-alpha), oxygen (OIII), and sulphur (SII) ions. Each filter unveils different aspects of this cosmic spectacle, highlighting the complex interplay between elements within this stellar environment. As we gaze upon this breathtaking scene, we are reminded of our place in the vast expanse of the universe. The Helix Nebula serves as a testament to the incredible forces at work in shaping our cosmos and offers us a glimpse into stellar evolution and astrophysical phenomena. With its vibrant colors contrasting against a backdrop filled with dust particles, this image not only appeals to astronomy enthusiasts but also ignites curiosity about our place in space. It reminds us that there is still so much left to explore and understand about our universe's mysteries.
