Emirates Astronomy monitors the “Bull’s Helmet” nebula in the country’s sky

The Emirates Astronomy Society observed the “Thor’s Helmet” nebula in the country’s sky, as part of its efforts to spread astronomical knowledge and document celestial bodies.

The Chairman of the Board of Directors of the Society, Ibrahim Al-Jarwan, said that the “Thor’s Helmet” nebula is one of the well-known emission nebulae in our galaxy, explaining that it was formed by strong stellar winds emanating from a massive Wolf-Rayet star, whose stars are known to be very massive and move at high wind speeds that may reach thousands of kilometers per second, making them one of the most influential stars in forming the surrounding nebulae.

He pointed out that these winds push the surrounding gases and form a distinctive helmet-like structure that appears in the form of arcs and glowing gas structures that reveal active physical processes in the interstellar medium.

He explained that the nebula is located at an estimated distance of 15,000 light-years from Earth towards the constellation Canis Major, and extends over an area of ​​approximately 30 light-years, making it a clear example of the profound influence of massive stars in reshaping their cosmic environments and enriching space with heavy elements that later contribute to the formation of new generations of stars.

Al-Jarwan stressed that photographing such nebulae contributes to bringing astronomical concepts closer to the public, and at the same time reflects the development of astronomical photography tools and techniques used by amateurs and researchers in the UAE. It also constitutes an addition to scientific research and observational data, pointing out that this work comes within the Society’s efforts to serve scientific research and astronomical observation, promote astronomical culture, and disseminate space astronomy among members of society.
