What a spectacle the inhabitants of Australia. Nothing more and nothing less than the drop of a meteorite I stay Recorded in video and? lit up the whole sky with flashes of green and other colors, an impressive event that went viral due to its relevance and astonishment.
The security cameras at Cairns Australia Airport were in charge of recording this phenomenon in a video that already circulates on various websites, as well as on social networks.
In this visual material you can see how the meteorite it enters the Earth and immediately gives off a green illumination that, moments later, lights up the sky, making it appear as if it were daytime, even highlighting a couple of clouds and showing a blue sky like the one you can see during the afternoon.
A few seconds later the illumination caused by the meteorite it turns white and impacting directly with the ground, which causes the light to turn orange and, finally, the sky turns dark again, without any other type of illumination generated by the fall of this great mass being perceived.
The fact that the drop of this meteorite causing a green light has to do with a possible overheating of some iron and nickel fragments at the time the large rock broke, moments before hitting the ground, also causing the flash and sound itself.
What is a meteorite?
A meteorite It is a space object of different dimensions, which can range from small clusters of dust grains to several kilometers in diameter, which penetrate into other planets outside where they were formed, surpassing the atmosphere.
It is a relatively small celestial body that, compared to asteroids, its dimensions are much smaller. The name of meteorite It comes from the Greek root “meteors”, which means “phenomenon in the sky”.
How is a meteorite formed?
Now, how is a meteorite formed? This rocky celestial body is formed thanks to the ionization of air when meteoroids are attracted by the gravity of other planets (in the case of Australia by Earth), and this makes them come into contact with the atmosphere, causing a friction that, when brushing with the air, endows them with incandescence.
The meteors They are composed of silicate minerals, which also exist abundantly in the earth’s crust. And although many of them are imperceptible to the human eye due to the sudden way in which they fall and the brief illumination, the scientific community estimates that up to 17,000 meteorites fall on Earth per year.
This is exactly what happened near Cairns airport Australiaa drop of a meteorite that lit up the whole sky and that was recorded for posterity and to be admired.
