Washington – The formation of both stars and planets has greatly being contributed by the role of various elements contained in the cosmic dust, the likes of oxygen, carbon, and iron. This is unlike what was found in the early galaxies that were said to contain gas only since the dust came years later and whose existence has been subjected to various scientific researchers.
Scientists have since found evidence through tracking of cosmic dust that it could be the violent star explosions commonly known as supernovas.
By the use of infrared images gathered by the Faint object Infrared Camera Telescope,a remnant of a supernova was located near the Milky Way and which was said to be having some good amount of cosmic dust.
As such and according to Ryan Lau who is the lead author of the study, getting to know where this dust that forms the stars and the planets is of essence. This is with the simple mentality that dust is such a fragile material and the questions that still remain an answered include, how does it survive in this very extremely hot environment?
“Our main duty is to give reinforcement to the theory that supernova produces the dust seen in the galaxies of the earlier years”, Lau explained.
The 10,000-year-old cloud of interstellar dust was found to have retained so much dust that had been created by the Supernova. According to Researchers the dust must have been within the range of 7 to 20 percent.
From Lau’s statement, a particular cloud which was produced10,000years ago by a supernova explosion has enough dust that can make up to 7,000 Earths.
“As it is now, no space-based telescope can observe at far-infrared wavelengths”. This was said by a spokesman from the University of Cornell. However, Lau has accredited the findings to the NASA Stratospheric Observatory and SOFIA for the Infrared Astronomy whose analysis were made on an altered Boeing 747SP jumbo jettraveling at 600 mph (965 km/h) at an altitude of 45,000 feet
