A new discovery shows a glass made of explosion stars



PARIS – The next time you look out of the window to look for inspiration, remember that the material you are looking for has formed in the center of an ancient star; n exploded.

An international team of scientists said on Friday that they had found silica – the main component of the glass – in the remains of two million light years of supernovae light of Earth.

The NASA Spitzer Space Spy Telescope researchers used to analyze the light emitted by the collapse of the mega cluster and having silica "fingerprints" based on a specific light wavelength that it is known that the material will emit.

Supernova occurs when a big star burns through its own fuel, causing a catastrophic collapse ending in an explosion of galactic proportions. In these celestial maelstromes, individual atoms join together to form many common elements, including sulfur and calcium.

Silica forms about 60 percent of the Earth belt and one specific form, quartz, is an important ingredient of sand.

As well as glass windows and fiberglass, silica is also an important part of the recipe for industrial concrete.

"We have shown for the first time that the silica produced by the supernovae was significant enough to contribute to dust through the Universe, including the dust that came together to form our home planet," said Haley Gomez from Cardiff University School of Physics and Astronomy.

"Every time we look through a window, walk down the pavement or turn on a sandy beach, we interact with material made by explosion stars and burn millions of years ago."

In 2016, scientists said they had discovered the lithium-metal extracts used in the production of a lot of modern electronics – at the heart of a new explosion, a phenomenon that occurs when a white dwarf star absorbs hydrogen from adjoining sun.

The study was published in the Royal Astronomical Society Monthly Notices.
