The convergence of the “humpback moon” and Mars in the sky of Saudi Arabia … and “Astronomical Jeddah” clarifies the details


The Astronomical Society in Jeddah explained that it is observed in the sky Saudi And the Arab world after sunset on Thursday and early night, the occurrence of the growing humpback moon near Mars in a phenomenon easily seen with the naked eye.

The chief astronomer of Jeddah, Eng. Majed Abu Zahra, said on the society’s Facebook page that during this month (October 2020) Mars replaced Jupiter as the fourth bright celestial body to illuminate the sky (after the sun, moon and Venus, respectively).

But with the beginning of November 2020, Jupiter will clearly regain its usual place in the celestial hierarchy, because the Earth, in its faster and smaller orbit around the sun, is now moving away from Mars; So the red planet is slowly diminishing in Earth’s sky, however, Mars will continue to shine more than a first-degree star until the end of 2020.

The chief astronomer of Jeddah added that Mars is currently brighter than Sirius (the brightest star in the sky). So it will be easy to see its red light despite the moonlight; To see the planet’s disk, the observer will need to use a telescope of 8 inches and larger. It is preferable to use color filters to improve the observation, as there is a wide range of suitable color filters; Where the green or blue filter will enhance the polar caps, the red or orange filter will improve dark details, as well as the use of a magnifying glass (Barlow) that connects to the eyepiece of the telescope to improve vision.

He explained that the southern half of Mars can be seen tilting towards the Earth, and dark and light areas are seen on the planet’s disk due to differences in light reflectance The lighter areas represent deserts while the darker areas are rocks.


In addition, the planet’s south polar dome shines brightly; But since it is in the southern summer, this dome will shrink to a fraction of its full size.

As for the Arctic Dome, it is currently behind the northern end of the planet, but there are blue clouds spread over it that can be observed, and the reason for its blue color is that it consists of ice crystals of water and carbon dioxide that scatter the short blue wavelengths of sunlight, knowing that rain does not fall on Mars Because its atmosphere is thin and the low temperatures and pressure mean that water can only exist there in the form of steam or ice.
