About 10,000 Grand pianos’ price Earth dust lands on Earth every year, according to a new study Published In Earth and Planetary Science Letters.
The discovery stems from expeditions to six French national scientific research centers in Antarctica, which spanned 20 years at the highly isolated Concordia research station. Concordia made a great place to display extrinsic dust because there was very little dust on Earth and very little snow accumulation despite being in Antarctica.
You can’t see this dust because it’s a particle, about 1/50th the size of a grain of sand. However, every year, researchers say, 5,200 tons of material from various cosmic sources fall from the sky. Researchers say the dust is probably driven by asteroids or comets and is the largest source of Earth’s space material.
It feels good to see the particles under the microscope Interplanetary cotton candy forbidden bit. These were collected which can only be considered as the gold prospect version of the 21st century: The research team collected a large bucket of snow, melted it and then threw water for anything falling from space.
From They are able to discover 2,000-odd bits and bobs from space, The team then excludes the amount of micrometric mass that the earth has each year. Most of those things are not objectionable, they get lost in the mundane of earthly activities, human and otherwise. The best meteorites in chemical analysis are those found in icy lakes or deserts. They are mostly devoid of the pollutants in our lives.
The researchers also conducted a chemical analysis to determine the source of the dust in space. They found that the primary source (80%) of the matter could be attributed to the comet. But the researchers also estimated that about 15,000 tons of dust were probably orbiting around us Before entering the Earth’s atmosphere The researchers wrote that some of the dust may not move.
Whatever the case, the inclusions of this dust are obvious. Since it came from a meteorite, there is a chance that dust could fill the holes in our understanding of carbonaceous chondrite, an ancient meteorite like the solar system seen as the main candidate to bring water to Earth.
Since this 5,200-ton dust estimate is annual, so is itA new endless stream of logical meaning The weather Data can Available Antarctica frozen sprawl. Researchers just need to keep up Don’t run Ready.
