ToggleAbu Dhabi Astronomers Achieve Major Milestone After Long Hunt for Faint ‘Squid Nebula’
Astronomers in Abu Dhabi have achieved a remarkable scientific milestone, successfully capturing an image of the extremely faint and elusive ‘Squid Nebula’ after an 18-month observation campaign. This accomplishment underscores the growing expertise and dedication of the UAE’s astronomy community.
The Observational Challenge
The effort was led by the Al Khatm Astronomical Observatory, located under Abu Dhabi’s dark desert skies. Imaging the Squid Nebula—a large, dim structure that emits primarily in ionized oxygen—presented a significant technical challenge. The team invested over 150 hours of observation time, taking more than 1,800 individual exposures over the course of a year and a half.
Technical Upgrades and Perseverance
Initially, the observatory’s equipment struggled with the nebula’s faintness and local light pollution. The team undertook a technical upgrade, installing a more powerful telescope and refining their imaging techniques. Each five-minute exposure was meticulously filtered and stacked to create the final composite image, which also features the brighter, reddish Flying Bat Nebula for striking contrast.
Scientific Significance and Mystery
The Squid Nebula spans over one degree of sky—more than twice the width of the full moon—yet remains poorly understood. Early theories suggested it was a planetary nebula, but current research views it as a complex gaseous outflow from a central star system. Its distinctive bluish glow comes from ionized oxygen, while the neighboring Flying Bat Nebula shines from hydrogen emissions.

A Milestone for UAE Astronomy
This success highlights the advancing capabilities of UAE-based astronomers and the region’s growing role in deep-sky astrophotography. It demonstrates that with persistence and advanced technology, even the most challenging cosmic objects can be captured from Earth’s surface, inspiring both local enthusiasts and the international scientific community.
The image of the Squid Nebula is more than a technical achievement; it is a testament to the beauty and mystery of the universe and a significant step forward in fostering a robust astronomy culture within the UAE.
