Our solar system may have formed inside a giant space bubble

What are you thinking About Bubble?
Do you like bubbles.
Ever feel like you live in a bubble?
Some body saying we already living in the bubbles.
Is it small bubble or large bubble,I don't know. But University of Chicago know about this, It's called the "Local Bubble" or "local hot bubble" 

Scientists have proposed a new method for the formation of our Solar System 4.6 billion years ago, suggesting it was born from a giant star shedding its layers rather than a supernova.

Published in the Astrophysical Journal, a study from the University of Chicago points towards a Wolf-Rayet star as the possible progenitor of our own Sun. These are some of the most massive and brightest stars in the universe.

The general prevailing theory is that our solar system formed billions of years ago near a supernova.

But the new scenario is different from all others, instead begins with a giant type of star called a Wolf-Rayet star, which is more than 40 to 50 times the size of our own sun. They burn the hottest of all stars, producing tons of elements which are flung off the surface in an intense stellar wind. As the Wolf-Rayet star sheds its mass, the stellar wind plows through the material that was around it, forming a bubble structure with a dense shell.

"The shell of such a bubble is a good place to produce stars," because dust and gas become trapped inside where they can condense into stars, said coauthor Nicolas Dauphas, professor in the Department of Geophysical Sciences.

The mystery of the solar system's formation will likely endure for years and years, as scientists scrutinize the Wolf-Rayet star theory to see if it holds, and come up with new ones altogether. But the clues we have left written in ancient space rocks that formed at the beginning of the solar systems life can tell us a great deal about the past. Perhaps when OSIRIS-REx—a NASA spacecraft on its way out to an old asteroid that orbits nearby, named Bennu—returns a sample of that ancient material to scientists on Earth in September 2023, astronomers will answer the question of the solar system's formation more completely.

Until that time, take comfort in the fact that there is a descent probability that everything you own, everything you can see from the sun out to beyond Pluto, and even the atoms of your body were once superheated plasmas of heavy elements in a dense shell surrounding an inferno of rapid fusion and eruptions that is a Wolf-Rayet star.

Once the shell of that super-bubble collapses, this is what eventually forms a solar system. There's a good chance that the potential Wolf-Rayet star which birthed our neighborhood is long gone, having collapsed entirely into a black hole lurking somewhere in the Milky Way. This too, would produce almost no iron-60, so even that fits with this scenario.

It could be a long time until we have a concrete answer regarding who our solar system's real parents are, but this certainly does answer some unexplained questions. Just don't expect us to go visiting our Wolf-Rayet father anytime soon.
