Meteor shower: how and when to see the Perseids


    Starfall: how and when to see the Perseids

    Like every year around this time, the meteor shower&nbsp ;of the Perseids, also known as Tears of Saint Lawrence due to its proximity to the maximum of themeteor showerIt illuminates the night skies at the end of July and beginning of August.

    According to the cató tradition Historically, this parallelism with the Christian tradition would seek to evoke the tears that the martyr shed. being burned alive at the stake. from there The poetic association between shooting stars and the deacon's cry.

    The Perseids, although they are not as spectacular or as showy as other meteor showers, stand out because they occur in summer, a season in which the atmospheric conditions are normally favorable  astronomical observation and, as a general rule, at a time when people have more free time to look at the stars. from there the emotion for the arrival of the tears of San Lorenzo.

    However, the December Quadrantids and the January Geminids would exceed their summer counterpart by  number of meteors per hour. At the same time, the Leonids, although more irregular, can also be as spectacular as the Perseids.

    Why? occur?

    The showers of stars, popularly known as shooting stars,They occur as a result of the entry of celestial bodies into the Earth's atmosphere. In the specific case of the Perseids, this astronomical phenomenon has its origin in the fragments of the comet 109P/Swift-Tuttle which, at a given moment of their orbit, come into contact with the Earth's atmosphere. An impact that, seen from the surface, generates the characteristic flashes of light of the tears of San Lorenzo.

    Every year, between the end of July and mid-August, Earth passes through a cloud of dust shed by the comet as it approaches the Sun. Perseid meteoroids hit our atmosphere at 210,000 kilometers per hour, producing that characteristic ;sticlight show.

    That is why it is wrong to speak of meteor shower, because the stars do not fall. so that the Perseids are nothing but fragments of dust and rock that disintegrate in the Earth's atmosphere.

    Most of the meteoroids released from Swift-Tuttle are small, sand-like fragments. When they hit the Earth's atmosphere, they increase their temperature to about 5,000 degrees Celsius in a fraction of a second, which causes them to disintegrate at a height of between 100 and 80 kilometers. That effect is what causes them to emit a flash of light. Larger particles, the size of a pea or even larger, can produce much brighter contrails, known as fireballs.

    What? When does it happen?

    This year, the peak of this phenomenon will have place the nights from August 11 to 13, when between 80 and 200 shooting stars per hour can be observed. Before and after this date, always taking into account the time range foreseen by astronomers, it will also be It will be possible to observe the meteor shower, although with less intensity.

    The show will be more intense. visible until August 24And, according to NASA, the best time to see the Perseids in the Northern Hemisphere is during the hours before sunrise, although they can also be seen at dusk, starting at 10 at night.

    < p>The Perseids, like any other meteor shower, can be seen from anywhere on the globe. However, depending on where we are, we will have more or less chances of enjoying the phenomenon in all its splendor. Since the tears of San Lorenzo appear as small flashes of light, to be able to distinguish them from the starry sky, you will have to do it. We need to find a place that is dark enough (with little light pollution) and with enough field of vision (from where we can have a wide view of the horizon). from there will do Patience is lacking, since there is no optimal time slot to observe the phenomenon.

    Strategic points

    Although it is true that any place can be good to enjoy the Perseids, for those who want to experience the phenomenon in all its splendor, it is best to go directly to an astronomical observatory. >. In these places, which already They have optimal visibility of the sky, during the days of the meteor shower talks, workshops and other activities are organized to observe the tears of San Lorenzo.

    For lovers of nature, the nature reserves are also positioned as a good place to enjoy the Perseids. By standing out as places secluded from the big metropolises, the absence of light pollution is an advantage. insured. In addition, in many cases these natural landscapes already count on their own. with spectacular views. So the tears of San Lorenzo would only manage to crown the territory.
