Books – Youssef Affifi:

In the skies of Egypt and the Arab world, this Thursday evening and the coming winter nights, the galaxy of Gemini or Orion stars, with the belt of the Milky Way behind it, is observed towards the eastern horizon in the evening. .

The Jetta Astronomical Society reports that due to the brightness of the Gemini stars, they can be seen with the naked eye from within the city, and as far as the Milky Way galaxy is concerned, it needs a darker location.

The association explained on its official Facebook page that Gemini stars are one of the three easiest constellations to be distinguished by three stars and that there are two bright stars on either side of them, one of which is the red star Petalgeus. , Another bright star, blue and white called the Gemini man.

He continued: “Since Gemini has long nights in the Northern Hemisphere in December and January, it is always associated with winter, and is a great starting point for exploring the Milky Way galaxy. The Milky Way stretches near the red star Betelgeuse to the naked eye.

When we look at this belt, we see the edge of the galaxy – the combined glow of billions of stars. Ironically, the Milky Way band appears to be bright in the evenings in August, and at that time we look forward to it. Galaxy center.

Now the globe has moved in its orbit around the sun, and the evening sky is pointing in a different direction, so when you look at the Milky Way galaxy near the Orion galaxy this month, you will see that it is much fainter than anything. Seen in August because we are now looking at the outer edge of the galaxy, with fewer stars between us and the intergalactic space.
