5,000 light-year-old nebula photographed in UAE: A first for Emirati astronomers
Crescent Nebula captured in stunning detail from UAE skies. (Tameem Al Tamimi / Emirates Astronomy Society) In a remarkable astronomical achievement, astrophotographers from the Emirates Astronomy Society (EAS) have captured breathtaking images of a distant nebula from the skies of the UAE. The phenomenon was spotted in the country's eastern mountainous regions, offering a rare and awe-inspiring view of the Crescent Nebula, an object located thousands of light-years away from Earth. What Was Seen: the Crescent Nebula The celestial object observed is the Crescent Nebula, scientifically designated as NGC 6888 and also known as Caldwell 27-Sharpless 105. This stunning emission nebula lies in the Cygnus constellation, roughly 5,000 light-years away from Earth. According to Tamim Al Tamimi, a member of the Emirates Astronomy Society and an astronomical photographer, the nebula was not only observed but also photographed in high resolution, providing a vivid glimpse into deep space from the UAE. How the Nebula Was Formed The nebula's origin is tied to a dramatic cosmic event involving a dying star. Ibrahim Al Jarwan, Chairman of the Emirates Astronomy Society, explained the formation process in a statement to WAM (Emirates News Agency). by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Memperdagangkan CFD Emas dengan salah satu spread terendah? IC Markets Mendaftar Undo He said the Crescent Nebula was created by strong stellar winds from a Wolf-Rayet star, known as WR 136, which clashed with material previously ejected by the same star during its red giant phase. The result is a massive glowing bubble of gas composed largely of ionized hydrogen and oxygen. 'This large gas bubble of ionized hydrogen and oxygen is formed and appears in fine detail when imaged using narrow-field techniques,' Al Jarwan noted. How the Image Was Captured The stunning images were the result of over 10 hours of observation, using specialized filters, H-alpha and O3, that help isolate specific wavelengths of light emitted by the nebula's chemical elements. The data was then processed using the HOO (H-alpha, OIII, OIII) scientific color mode to clearly reveal the chemical structures within the nebula. Capturing these detailed images required a combination of advanced equipment and careful planning. The setup included: Camera: Cooled ZWO ASI183MM Pro Telescope: Explore Scientific 152mm David H. Levy Comet Hunter Maksutov-Newtonian Mount: iOptron HAE43 Guidance System: ASIAir Plus Post-Processing Tools: PixInsight and Photoshop A Milestone for Emirati Astronomy The observation and photography of such a distant and intricate deep-sky object underscore the dedication and technical expertise of UAE's growing astronomy community. Al Jarwan emphasized that this achievement reflects the resilience of Emirati astrophotographers, who continue their work despite harsh environmental conditions. 'Night-time temperatures during the photographing period sometimes reach between 36 and 40 degrees Celsius in the mountainous or desert regions,' he said. This sighting not only showcases the beauty of space but also positions the UAE as an emerging center for serious astronomical observation and documentation, especially in regions not traditionally associated with deep-sky astrophotography.

Look: Jaw-dropping nebula spotted in UAE skies, 5,000 light-years away from Earth
In a stunning astronomical spectacle, a nebula was spotted in UAE skies by photographers of the Emirates Astronomy Society (EAS) in the eastern mountainous regions of the country. The Crescent Nebula (NGC 6888), also known as Caldwell 27-Sharpless 105, is located in the Cygnus constellation, approximately 5,000 light-years from Earth. The nebula was observed and photographed in high resolution, according to Tamim Al Tamimi, a member of the society and an astronomical photographer. While speaking to WAM, Ibrahim Al Jarwan, Chairman of the Emirates Astronomy Society, revealed the nebula was formed by strong winds from a Wolf-Rayet star, WR 136, which collided with the material ejected by the star during its red giant phase. This large gas bubble of ionized hydrogen and oxygen is formed and appears in fine detail when imaged using narrow-field techniques. The observations took place over 10 hours using H-alpha and O3 filters, with the image processed according to the scientific color mode HOO, which clearly shows the chemical differences within the nebula. The images were captured with a cooled ZWO ASI183MM Pro camera using the Explore Scientific 152mm David H. Levy Comet Hunter Maksutov-Newtonian telescope on an iOptron HAE43 mount, with ASIAir Plus guidance, while final processing was performed using PixInsight and Photoshop, Jarwan added. In an important feat for UAE astronomers, the sighting highlights the commitment of Emirati astrophotographers to observing and photographing deep-sky objects despite the climatic challenges in mountainous or desert regions, where night time temperatures during the photographing period sometimes reach between 36 and 40 degrees Celsius.
