Weather of Arabia - Although part of July has passed, the remainder of this month is still full of various astronomical events, some of which we will be able to see with the naked eye without the need for telescopes or binoculars, and among these astronomical events:
July 12 - Conjunction of the Moon and Jupiter
The moon rises in conjunction with Jupiter (the largest planet in the solar system) on this day, as we see them with the naked eye in the sky towards the east at approximately 1:45 am, and this scene appears until it disappears from the intensity of the morning twilight as a result of sunrise.
On July 13, the moon will conjunct the Pleiades star cluster (The Pleiades), one of the brightest and most famous open star clusters in the northern sky, located 440 light-years from Earth.
This crowd consists of several hundred stars, but its brightest stars are only 7 that can be seen with the naked eye, so it is called the Seven Sisters. the sun ..
On July 14 and 15, Mercury (the closest planet to the Sun) will conjugate with the Beehive star cluster in Cancer, an open star cluster located 580 light-years from Earth, with an age of 600 million years.
This pairing can be seen when night enters at that period by using magnifying glasses or a small telescope (because it is difficult to see the beehive crowd with the naked eye). The sunset of this scene begins by approximately 9:50 pm..
On July 17, the moon will not be visible in the sky all night on that day, marking the beginning of the birth of the new moon, as the moon rises with the sun and sets with it completely, so that its luminous face is facing the sun, and therefore its dark face is facing the earth.
This night is considered the best night during the month in general, which is preferred by astronomers a lot, as faint celestial bodies such as galaxies, star clusters, and distant constellation stars are spotted.
On July 19, the moon will conjugate with the planet Mercury (the closest planet to the sun: the messenger of the gods) on that day, and this conjugation can be seen towards the west immediately after sunset until approximately 9:00 pm, when the scene begins to set.
On July 20-21, the moon is associated with Venus (the brightest planet in the solar system), Mars (the red planet), and the star Regulus (the heart of the lion), which is the brightest star in Leo. Its mass is 3.5 times the mass of the sun and it is about 79 light years away from us. .
And this wonderful quadruple conjunction can be seen towards the west after sunset and the entry of night on these two days, when the moon is between Venus and Mars on July 20, then above them in conjunction with Mars on July 21, noting that this scene begins to set at approximately 9:20 pm .. And then the moon begins to move away from this scene, starting from July 22.
On the 27th and 28th of July, Venus (the brightest planet in the solar system) is paired with Mercury (the closest planet to the sun: the messenger of the gods) and the star Regulus (Regulus the Heart of the Lion) on this day, and this triple conjunction can be seen towards the west at nightfall. Until the sunset of the scene by approximately 8:45 pm on July 27, as the planet Mercury is associated with the star Regulus, as this scene is seen at nightfall on July 28 until sunset at approximately 9:5 pm..
On this day, the moon is paired with the star Antares (the heart of the scorpion), a giant red star whose mass is ten times the mass of the sun and 600 light-years away from Earth. : 00 am of the next day.
At the end of the month, we will have a date with the Delta Aquarius meteor shower, which is a medium-intensity meteor shower, with a number of meteors reaching 20 meteors per hour. These meteors come due to the entry of the debris of the two comets (Marsden and Kracht) into the earth’s atmosphere from July 12 to 23. August and culminates in the night of the 29th and the dawn of July 30th.
This year, the moon will hinder seeing many meteors, especially the weak ones, and generally the best conditions for viewing meteor showers are from a completely dark place away from the city lights after midnight, provided that the sky is clear and free of dust, clouds and water vapor, and the meteors appear as if they were coming from a constellation Aquarius, which is the reason for its name, but it can appear anywhere else in the sky.
