Exploding stars have become the main ingredient in sand and glass, according to a new study – new technology, Firstpost


The next time you look out the window in search of inspiration, remember the stuff you are looking through was fake in the heart of an exploding old star.

An international team of scientists said on Friday that they identified silica – the main component of glass – in the remains of two billion supernova distant light years from Earth.

The researchers used NASA's Spitzer Space Telescope to analyze the emitted light by folding a mega-cluster and obtain the silica fingerprint based on the specific wavelength of light known to emit.

A supernova occurs when a large star burns in its fuel, causing a catastrophic collapse that ends with an explosion of galactic proportions.

It is in these celestial degrees that single atoms merge together to form many common elements, including sulfur and calcium.


Silica forms about 60% of the Earth's crust and one particular shape, quartz, is a major component of sand.

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

"We showed for the first time that the silica produced by the supernovae was significant enough to contribute to the dust throughout the universe, including dust in the end to create our planet home," said Haley Gomez, from the University of Cardiff's School of Physics and Astronomy.

"Every time we look out the window, down the sidewalk or set foot on a sand beach, we work with material created by exploding stars that were burned millions of years ago."

In 2016, scientists reported that found traces of lithium – a metal used in the manufacture of many modern electronics – in the heart of Nova explodes, a phenomenon that occurs when a white dwarf star absorbs hydrogen from the coming sun.

The study was Posted in God Monthly Notices of the Royal Astronomical Society.
