"Alien" a speck of dust on the baked earth of ancient exploding stars found buried in Antarctica – and could show how our solar system was born

Scientists have found a "foreign" mote that survived the birth of our solar system.

It is believed a tiny speck of material found in a meteorite in Antarctica, was created by a distant star as it was destroyed in a huge explosion.

The star died long before our Sun even existed, and experts believe the newly discovered fragment may shed light on how the solar system was born.

This is because the small grains of star dust, believed to be from & # 39 are the key building materials in the birth of new stars and planets – as well as life as we know it.

"As the actual dust from stars such presolar grains give us an idea of ​​the building blocks from which formed our solar system," said Dr. P & # 39; er Haenecour, lead author of a new study about the discovery.

"They also give us a direct image of the star in terms of the time it was formed by the grain."

    StarDust was discovered in Antarctica in chondrite meteorite, as shown in Figure

Antarctic meteorite was found and collected by NASA and then analyzed by scientists from the University of Toronto.

They use state of the most advanced microscopes to study the atoms that make up the space rock, and found a small fragment containing an odd mixture of graphite and silicate grains.

It turns out a little piece of StarDust material that scientists have named LAP-hundred forty and ninth

It is believed that formed 4.5billion years ago, after the violent death of a star, known as a supernova explosion.

Overthrown unimaginable distances through space, the grain eventually landed in a region where our solar system would later form, it will fall in the primitive meteorite.

Interstellar journey, such as they are essential for the formation of new solar systems, the scientists said.

    The dust is believed to have come from an exploding star, also known as a supernova. Pictured is the supernova Cassiopeia A

They provide the worlds originate chemical elements such as carbon and oxygen, contributing to the spread of the key building blocks for life in remote corners of the galaxy.

The study provides new insights into the conditions of a dying star.

This is also contrary to long-standing belief that these two types Stardust material rich in oxygen and rich in carbon, – which from the & # 39 are the building blocks in the formation of solar systems – can not form in the same explosion star.

Scientists hope to examine large pieces of stardust in the future to get a better idea of ​​how life began in our solar system.

"This kind of research is part of a broader debate about how life began on Earth," said University of Toronto scientist Professor Jane Howe.

"We all care about who we are and where we came from."

The study was published in Nature.

In other news space, Nasa boss Jim Bridentstine recently warned that the brunt of the asteroid on Earth can happen in our lives.

The space agency is currently preparing for the apocalypse with a five-day "end of the world» RolePlay game.
