Speculations have no end when it comes to any theories related to the origin of the universe or the solar system. A new research reveals that it is quite probable that the entire solar system was formed out of bubbles that produced by a star that was long dead and with a size assumed to be about 40-50 times the sun. The theory explained in the Astrophysical Journal rejects the prevailing held theory that the solar system was formed near supernova some billions of years back.

This kind of theories only gives rise to the question that whether scientists around the world are ever going to come to an agreement regarding the origin of the solar system. The massive dead star from which the bubbles are assumed to have emerged is called a Wolf-Rayet star.

Co-author Nicolas Dauphas the one who co-authored the study at the University of Chicago went revealing that as the giant star shedded its mass, the stellar wind plows through the material around it forming a bubble-like structure but 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”.

As per the sources, researchers estimate that 1% to 16% of all sun-like stars could be formed in such stellar nurseries. Meanwhile, the study revealed that meteorites left over from the early solar system have a lot of Aluminium-60. In addition, the solar system had less of the isotope iron-60. Supernovae produce both isotopes.

“It begs the question of why one was injected into the solar system and the other was not,” said co-author Vikram Dwarkadas from the University of Chicago. Now, this brought the scientists to Wolf-Rayet stars, which release lots of aluminum-26, but no iron-60. The Wolf-Rayet star is believed to have ended like a supernovae explosion or a direct collapse of the black hole.
