Dr. Ashraf Tadros, former head of the astronomy department, revealed at the National Institute for Astronomical and Geophysical Researchabout the most important phenomena andastronomical events During the current month of July, most notably the appearance of Delta Aquarius meteor shower.
Tadros said: Please bear in mind that all observations of astronomical phenomena and events require a clear air and that the sky is free of clouds, dust and water vapor.
He summed up “Tadis astronomical events” during a month in a number of phenomena:

The Summer Triangle of three shining stars: Altaïr (Flying Eagle) – Vega (Veagle) – Deneb (hen’s tail) continues to appear throughout July from nightfall to dawn.
The five planets (Mercury, Venus, Jupiter, Mars and Saturn) continue to appear at dawn before sunrise, but Mercury will leave the scene after the first week of July with the four planets continuing to appear at dawn until the end of the month.
July 10 – Moon and Antarius
The moon is paired with the bright star Antarius (Antares – red in color) located in Scorpio, where we see them next to each other in the sky at nightfall until it sets at 2:00 in the morning of the next day.
July 13 – Full Moon (Badr Dhu al-Hijjah)
The moon appears to us as if it were a full moon in the period from July 12 to 14, as the naked eye cannot distinguish the entire rotation of the moon’s disk during this period without devices. As for the height of the full moon, it will be on July 13, when the moon’s disk is complete and its luminosity reaches 99.5%.
This full moon is known to American tribes as the Thunder Moon, and it is the second giant moon among the three giant moons for this year. It is usual about 30%, and the time of the full moon is the best time of the month to observe the terrain, volcanic craters and meteorite craters on the moon’s surface using binoculars and small telescopes.
July 15 – Moon and Saturn conjunction
The moon is associated with Saturn on this day, as we see them next to each other in the sky at sunrise at 9:00 pm and remain in the sky until the next morning.
July 19 – Moon and Jupiter conjunction
The moon is associated with Jupiter on this day, as we see them next to each other in the sky at sunrise at 11:00 pm and remain in the sky until the next morning.
July 22-21 – conjunction of the Moon, Mars and Uranus
The moon is conjunct with Mars in these two days, as we see them next to each other in the sky when they rise within the hour 1:00 after midnight, the moon is to the right of Mars on 21, then to the left of Mars on July 22 where it is on this day also in conjunction with the planet Uranus But we cannot see it with the naked eye, as it requires a small telescope or magnifying glasses, and the scene remains visible in the sky until the next morning.
July 23 – Moon and Pleiades
The moon is associated with the star crowd Al Thuraya (the Seven Sisters or Plaids) located in the constellation of Taurus, where this scene appears at about 1:00 after midnight and remains in the sky until it disappears with the increase of the morning twilight light due to the rising sun.
July 27-26 – Moon and Venus conjunction
The moon is conjunct with Venus (the brightest planet in the solar system) in these two days, as we see them next to each other in the sky at their rising at 3:45 am, when the moon is above Venus on the 26th, then it is to the left of Venus on the 27th, and they remain in the sky until They disappear with the increase of the morning twilight light due to the rising of the sun.
July 28 – New Moon (Muharram)
The moon rises with the sun and sets with it on that day when its luminous face is facing the sun and the dark face or shadow is facing the earth, so the moon will not be visible in the sky all night on that day.
This night is considered the best night during the month, which is preferred by astronomers a lot, where faint celestial bodies such as galaxies, star clusters and stars of distant constellations are observed.
July 29-28 – Delta Aquarius meteor shower
It is a medium-intensity meteor shower, with the number of meteors reaching 20 meteors per hour. These meteors are produced due to the entry of the remnants of the debris of the two comets (Marsden and Kracht) into the Earth’s atmosphere from July 12 to August 23 and peaking on the night of 28 and dawn of 29 July.
Seeing the delta aquatic meteors this year will be very good because of the new moon, which means a completely dark sky. The best conditions for watching 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 and clouds.
Meteors appear as if they came from the constellation Aquarius, but they can appear anywhere else in the sky
July 29 – conjunction of the Moon and Mercury
The moon is associated with the planet Mercury on that day, where we see them next to each other in the sky after sunset, until it sets as well at 7:30 pm.
