"Every time we look through a window, walk on a sidewalk or step on a sandy beach, we interact with material that comes from a star explosion that was burned millions of years ago," said an international team of scientists in the study.
The medium determines that it is a material known as silica, which constitutes about 60% of the earth's crust and whose form in particular, quartz, is an important component of sand. With the help of NASA's Spitzer Space Telescope, the researchers found silica in the remaining two supernovas, which lie billions of light years from Earth.
Supernovae are produced when several types of dead stars explode, and at the "sky vortex" atoms combine to form many common elements, such as sulfur and calcium, explaining the medium.
"We have shown for the first time that the silica produced by supernovae is significant enough to contribute to dust in the entire universe, including dust that eventually unites to form our planet," said Haley Gomez, a specialist at the School of Physics. and Astronomy from Cardiff University.
