Astrophotographer Ogetay Kayali has captured a nebula resembling a jellyfish — or possibly a brain, depending on your perspective — shining 5,000 light-years from Earth near the bright star Propus, which represents one foot of a mythological twin represented in the constellation Gemini.
Kayali’s nebula view highlights the expanding structure of IC 443’s luminous shell, which is visible to the upper right of the image, glowing alongside dense filaments of interstellar dust and gas punctuated by the multicolored light of stars in the foreground and background of the nebula. “This image captures the intricate shock fronts where stellar debris collides with surrounding interstellar gas, causing hydrogen to glow in deep crimson while faint filaments trace the blast wave’s turbulent history,” Kayali told Space.com in an email.
The distinctive appearance of IC 443’s shell-like structure has led to it being nicknamed the “Jellyfish Nebula,” owing to its resemblance to the aquatic creature — though, through clever capture, processing and angling, Kayali opted to highlight the nebula’s similarity to a human brain in his composition.
ZWO ASI533MC Pro
In our opinion the ZWO ASI533MC Pro camera is the best dedicated astro camera out there. It featuresa 9MP sensor with zero amp glow, 80% quantum efficiency and a 20FPS frame rate. Check out our ZWO ASI533MC Pro review for a more in-depth look.
“Ironically, jellyfish do not have a brain!” Kayali said. “Rather than isolating the bright shell alone, I framed the wider environment to reveal how the remnant interacts with its surroundings, emphasizing the contrast between emission structures and darker molecular clouds.”
Kayali captured the nebula scene over the course of 17 hours as it glowed in the skies above Texas using his William Optics Redcat 51 III WFID telescope paired with a ZWO ASI2600MM astronomy camera and H-alpha filter.
