Thank you for reading the news about Jeddah Astronomy: It detects the brightest “stars” during the winter period, and now we begin with the details.
Dammam – Sharif Ahmed – The brilliance of the stars is observed when viewed with the naked eye on winter nights compared to the rest of the days of the year. During the months of December, January, and February, the part of the Earth on which we live faces the outer part of the spiral arm in the Milky Way galaxy, to which the sun belongs, and by directing the gaze Towards the stars where they appear clearer.
The head of the Astronomical Society in Jeddah, Engineer Majid Abu Zahra, said: “During the summer months of June, July and August, the night sky is towards the center of our galaxy, where the lights of billions and billions of stars combine, causing the sky to appear foggy and unclear. Our Milky Way galaxy has a diameter of about 100,000 light-years.” Its center is about 25,000 to 28,000 light-years away, and we cannot see that center because it is hidden behind galactic dust.”
Majid Abu Zahra pointed out that the spiral arm of the galaxy in which the Sun is located is called (Orion Arm), (Orion Arm), (Local Arm) or (Orion-Cygnus Arm), and it is a small arm with a width of about 3,500 light-years and a length of about 10,000 light-years. Our solar system is located within Orion’s arm, specifically near the inner edge and approximately half the distance of the length of the arm itself.
Abu Zahra explained that the arm of the galaxy was named “Orion” in reference to the group of stars of Orion, or as it is known to the Arabs as Gemini, which shines in the night sky during the winter season, as it is now, and these stars are also found within Orion’s arm in the Milky Way Galaxy.
