Deneb, one of the brightest stars in the night sky, is a luminous supergiant located approximately 2,600 light-years away in the constellation Cygnus. As the anchor of the Summer Triangle and the tail of the celestial Swan, Deneb shines with a magnitude of 1.25, making it visible even in light-polluted areas. Its staggering luminosity—nearly 200,000 times that of the Sun—places it among the most luminous stars known, marking it as a key point of interest for astronomers.
Captured from Annecy, France, during a brief window before a major target rose, Deneb's brilliance dominates the field, its blue-white light hinting at its surface temperature of about 8,500 K. Deneb's role as the ionizing source for the nearby North America and Pelican Nebulae adds to its allure, emphasizing its influence on the surrounding interstellar medium. Even as an impromptu target, this celestial gem reveals the grandeur of the cosmos with stunning clarity.
