Dr. Ashraf Tadros, former head of the astronomy department of the National Institute for Astronomical and Geophysical Research, revealed an astronomical phenomenon that is occurring in the world’s sky tomorrow Wednesday and will continue for 18 days until November 7.
Tadros explained to “Masrawy” that the phenomenon is represented by the Jabaria meteors, which are medium showers, and their number reaches 20 meteors per hour, these meteors are produced by the grains of dust left by the comet, the famous Hali.
He added that this rain will last from October 21 to November 7, and this year it reaches its climax on the night of October 21 and morning of October 22, provided it is best viewed from a dark place away from city lights after midnight, and the meteorites appear as if they came from a constellation. Powerful, but it can appear anywhere in the sky.
Tadros said that the rate of meteor fall depends on the degree of opacity of the monitoring area, which must be completely away from city lights, and also on the absence of clouds, fog or dust in the sky at the time of the observation.
He pointed out that the reason for the fall of meteor showers in general is due to the entrance of the earth during its orbit around the sun in the path of ancient comets that leave their remnants and their residues along their paths around the sun. , when these wastes enter the Earth’s atmosphere and burn in the upper atmosphere, causing the phenomenon of meteor showers.
He continued: Meteorites are usually called by the name of the constellation or the group of stars in which they appear as if they came from them, since this group is located at the bottom of the area from where the meteors fall in the sky, which indicates that sky watchers should be aware of the shape of the group of stars from which the rains come. Shehab, noting that there is no rush to judge the dark sky while observing meteorites at night, because the human eye needs at least 10 minutes to adjust and adapt to the darkness of the sky.
Regarding the benefits and harms of the phenomenon, Tadros said that the phenomenon has absolutely no harm to humans or their daily activities on Earth, as it is interesting in its observations and is loved by astronomers and those interested in observing. the sky to follow and photograph it, since the recurrence of meteors falling in one night seems like fireworks.
