Found !: Tremendous cometary dust for the first time on Earth – Ideal Digital

A new and recent discovery that was published by scientists from various universities in the world, reveals the first discovery of comet dust on earth. A group of scientists from several universities encontrópartículas dust from comet.

Find a comet material is not easy, obvious, as might be expected. To do this, we must also send probes to these celestial bodies (such as Rosetta) or research aircraft into the stratosphere and research. But the recent discovery of comet dust in Antarctica has been amazing, the Earth itself.

A new finding at revolutionizing astronomy, since they seem to have found traces of dust from something that might be a comet. To find it has not been easy but eventually they succeeded and also surprised that these particles are able to stay because the conditions presented to them on Earth.

The Most

A team of researchers from Japan and the United States has found particles of comet dust on the surface of the Earth. This finding, which had not occurred ever, was conducted in Antarctica, where ice extracted from the area to be studied.

In an article published in Earth and Planetary Science Letters, the study’s authors have stressed that “has not been easy to find samples of a comet”. Specifically, have had to drill the ice about 17 meters in the place known as Tottuki Point, and samples of the area were taken after the lab.

Also, collected particles floating around in the atmosphere, to which a sticky sheet is used. This method traps dust in the air, but leaves oils that litter samples. Ice obtained after melt it in the lab and analyze it, has allowed scientists to find dust particles that initially believed belonged to a meteorite and finally determined to be chondritic-particles of interplanetary dust. That is, it was possible that its origin was a comet.

This is the first discovery of remains of a comet on the surface of the Earth. In fact, before the discovery, scientists believed that the tiny dust particles never survive a trip through the atmosphere, much less to the harsh conditions that were presented once on Earth.
