A fireball over Alberta last year caught the attention of international stargazers and stargazers, who made exciting discoveries about where the meteor came from, reports RT.
Astronomers and astronomers, led by scientists from the University of Western Ontario (or University of Western Ontario) have managed to capture images and video of a stony meteorite that streaked across the sky in central Alberta like a spectacular wildfire in 2021.
Now they have shown that the fires lit at the ends of planets orbiting the sun must have been made of rock, not ice, challenging ancient beliefs about how the planets moved.
At the edge of our solar system, and midway through nearby stars, is a collection of icy objects floating in space called the Oort Cloud. tails.
Scientists have yet to find any material directly in the Oort cloud, but everything found so far that has its origin is made of ice.
In fact, understanding the origin of our solar system rests on the fact that there are only icy bodies in these outer regions and certainly nothing of rock.
And that opinion changed last year after observing a stone meteorite that flew across the sky over central Alberta in the form of a fireball, as scientists have since concluded that all signs point to the l origin of the body was central. “The Oort Cloud”.
The findings were published in the journal Nature Astronomy and Dennis Vida, a meteorite physics researcher at the University of Western Ontario, said: ‘This discovery supports an entirely different model for the formation of the solar system, and it is a model that supports the idea.Most rocks are icy bodies within the Oort cloud, and this was not the case.
And all the previous rocks came from afar from the Earth, which made this body unexpected, which traveled a long distance.
The cameras of the Fireball Global Observatory, developed in Australia and managed by the University of Alberta, have seen rocks similar to “grapes” (about 2 kg) and using the instruments of the Global Meteorite Network, scientists from the university. The Western Ontario team assumed the ball was moving in a constant circle.
As it flew, the Alberta fireball descended deeper into the atmosphere than solid objects that passed through similar paths, breaking apart like a fireball, evidence that it was made of rock.
In contrast, comets are soft snowballs mixed with dust that slowly evaporate as they get closer to the Sun, and the dust and gas inside them form a special tail that can stretch for millions of kilometers.
