Dust is everywhere, but cosmic dust is a little rarer. Cosmic dust, the material that is left behind from the creation of solar systems and galaxies has been found on the rooftops of buildings in three major European cities.
Before this, the cosmic dust had only been found deep in the oceans or in Antarctica. The dust gets to the earth’s surface by drifting through the atmosphere.
It was thought that the dust would never be found in a populated area. The dust is concealed in the pollution that all big cities emit.
Scientists usually collect cosmic dust in the frozen wastes of Antarctica. Now, for the first time, the space debris has been found hidden in city dirt.
Despite the likelihood, the cosmic dust was found on the rooftops of Paris, Oslo, and Berlin. It was found by a group of scientists from Imperial College.
COSMIC DUST PARTICLES FOUND ON ROOFTOPS
To find and identify the dust, two principal scientists at Imperial College studied and sifted through over 300 kilograms of sediment, or dirt and debris, from the gutters of the mentioned cities.
The finding of this dust is important for a few reasons. First, the dust shows what minerals and chemical compounds existed while the solar system was being created. This paints a picture of the timeline in which the solar system was created, and has given scientist in the past a glimpse into the past. Some ever refer to the specks of dust as “miniature time capsules.”
It is estimated that there is still much information scientists do not know about the creation of the solar system, and new data is expected to help them gain more information and insight.
Secondly, it was thought that it would be impossible to obtain dust from populated areas. Scientists fully expected that the only dust they would collect for a while would be the dust from Antartica. This made it harder to gain data due to living conditions and lack of collection area.
It is unclear what this discovery might bring, but it is clear that it is significant.
