The Astronomical Society of Jeddah, Saudi Arabia, said that November is the “month of the Pleiades”, as a cluster of stars will decorate the skies of Saudi Arabia and the Arab region after the beginning of the night and until dawn the next day.
She added that the Thuraya cluster, also known as the “Seven Sisters”, will be seen not only in the Arab world, but everywhere, from the North Pole to the furthest point in South America.
This cluster of stars resembles the stars of Ursa Minor, except that it has a nebulous appearance, and it is necessary to use an optical aid (binoculars) to see this cluster from within cities due to light pollution.
The Pleiades are an open galaxy cluster containing about 500 stars. According to recent measurements, the Pleiades were born from the same cloud of gas and dust only about 100 million years ago compared to the Sun’s age of 4 and a half billion years.
And these seven sisters are flying together through space, and many of them are thousands of times brighter than the sun.
When taking pictures of this cluster, the effect of the nebula from which these stars were formed will appear, and through binoculars many other stars will be visible, and through a large telescope some nebular material can be seen around the stars.
In general, the Pleiades star cluster is visible in the northern hemisphere throughout the night, coinciding with late autumn and advancing into winter, and the chandelier can easily be imagined as a frozen spot on the dome of the night sky.
The second phenomenon is related to the planet Venus, which can be observed in the sky of the Arab world before sunrise throughout the month of November.
During this month, Venus, the brightest planet, will be at the dome of the sky, as it can be easily seen on the eastern horizon with the naked eye in its brightest resolution.
Venus will appear to the observer with the naked eye as a bright white point of light, and when seen through a standard telescope, it will notice that the size of its apparent disc has shrunk as its brightness increases, as it appears in the hump stage, which is 81% lit by sunlight today.
The planet Venus moved from the night sky to the early morning sky on June 3, 2020, in a phenomenon called internal conjunction, and this happens once every (584 days), and then it hit on July 10, 2020 its maximum brightness in the dawn sky in what is called (the greatest amount of illumination).
It is mentioned that in ancient times, Venus was called (Hesperus) when he was seen in the night sky and (Vespor) when he was seen in the night sky, and it is not known whether the ancients knew that they were a celestial body.
