[EN] Noctilucent cloud catched? / [PL] Czy złapałem obłoki srebrzyste?
[EN] A few days ago I captured clouds in the northern sky that were highlighted in silver.
It turns out that (if this is indeed what they are), they are not clouds... at least not ordinary ones. These are noctilucent clouds located at an altitude of about 70 km, in the mesosphere layer.
If nothing tells you whether 70-80 km from the ground is high, then, for comparison, ordinary clouds can be found at altitudes of up to 12 km, and passenger planes and fighter jets also fly at altitudes of 10-12 km from the ground. About 20-50 km from the earth there is an ozone layer that protects us. You can see burning meteorites at an altitude of about 50 km from the earth.
And these clouds are still several dozen kilometers higher.
These are micro ice crystals illuminated by the sun hidden behind the horizon, become silver in the evening and night sky. Why they appear almost at the edge of atmosphere? And here, there is no clear answer...
One theory says that it was meteors dust, their appearance is also related to rocket flights.
[PL] Kilka dni temu na północnym niebie uchwyciłem chmury, które były podświetlone na srebrno.
Okazuje się, że (jeśli to rzeczywiście to), to nie są chmury... a przynajmniej nie takie zwykłe. To obłoki, które znajdują się na wysokości około 70km, w warstwie mezosfery.
Jeśli nic nie mówi Ci, czy 70km od ziemi to wysoko, to dla porównania zwykłe chmury są na wysokościach do 12 km, na wysokościach 10-12km od ziemii latają też samoloty pasażerskie i myśliwce. Około 20-50km od ziemi jest chroniąca nas ozonosfera. Spalające się meteoryty widzisz właśnie na wysokości około 50km od ziemi.
A te obłoki są jeszcze kilkadziesiąt kilometrów wyżej.
To mikro kryształki lodu, które podświetlone schowanym za horyzontem słońcem srebrzą się na wieczornym i nocnym niebie. A skąd się tam biorą prawie na granicy kosmosu? I tu, nie ma jednoznacznej odpowiedzi...
Jedna z teorii mówi, że to pył meteorów, ich pojawianie wiąże się też z przelotami rakiet.
