Finally Space cauliflower from meteorites Revealed
The origin of the microscopic meteorites that make up cosmic dust has been revealed for the first time in new research. …
The research shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space.
Cosmic dust particles, originally from asteroids and comets, are minute pieces of pulverized rock. They measure up to a tenth of a millimeter in size and shroud the solar system in a thin cloud. Studying them is important because their mineral content records the conditions under which asteroids and comets were formed over four and a half billion years ago and provides an insight into the earliest history of our solar system.
The study’s author, Dr Mathew Genge, from Imperial College London’s Department of Earth Science and Engineering, has trekked across the globe collecting cosmic dust. He says: “There are hundreds of billions of extraterrestrial dust particles falling though our skies. This abundant resource is important since these tiny pieces of rock allow us to study distant objects in our solar system without the multi-billion dollar price tag of expensive missions.”
The origin of the cosmic dust that lands on Earth has always been unclear. Scientists previously thought that analyzing the chemical and mineral content of individual dust particles was the key to tracing their origin. But this study suggests that a comparison of multiple particles gives better results.
