Secrets of the dark sky: motorized objects for caution

Secrets of the dark sky: motorized objects for caution

With Halloween approaching, the yellow night sky asks us to gaze at the cosmic depths, apparently motor-driven objects. NASA proposes to trace two celestial birthmarks: the mysterious star Algol, known as the “Demon”, and the “Witches Head” nebula, which appears in the vicinity of distant stars..

“Demon” Algol: the fiery eye of Medusa.

The names “Demon Star” and “Witch” (Ghoul) are not identical. The sage of Perseus acquired the triple dawn of the Algol system. Two of these stars wrap around one another, creating a darkening effect that forces the system to change its brightness. This process, which lasts for about three days, causes Algol to transform from a bright dawn (+2.1 bright values) to a little darkness (+3.4 bright values). According to data from the TESS (Transiting Exoplanet Survey Satellite) space telescope, this phenomenon apparently has the “quiet eye” of the mythical Gorgon Medusa, whose image is associated with these planets.

How to know Algol? It is necessary to pay attention to the susirs of Cassiopeia and Andromeda, who appear at the daily meeting after 21:00. The Mirror of Almach (Gamma Andromedae) in Andromeda may become a monstrous reference point for the identification of the “Demon Mirror”.

Witch's Head Nebula: cosmic silhouette.

Between the nodes of Eridan and Orion there is a motor-like silhouette – the knock-out nebula IC 2118, or “Witch’s Head”. This cosmic object, located approximately 900 light years from the Earth, is illuminated by the deepening light dawn of Rigel. Fragments of the knock-out nebula become visible in the glare of nearby stars, the “Witch’s Head” is quite a collapsible object for guarding with an unbroken eye, especially at such a significant distance.

However, with the help of large aperture telescopes and low magnifications, under clear dark skies, its motor circuit becomes accessible. Astrophotographs, based on various smart telescopes, can capture this primary image for many years, depending on the strength of the possession of celestial minds.

What can be added to the image of the witch, the lower broom Look for a “witch’s broom” in the outer part of the Veil Nebula, which is located in the swan of Cygnus.
