A new study is based on stellar nursery in the neighboring galaxy M33 and Tia the universe born from the dead helped answer the eternal question: ”Where do we come from? “.
According to Daily SciTecha team of scientists led by the National Radio Astronomy Observatory (US) used the US National Science Foundation’s Karl G. Jansky Very Large Array (VLA) telescope to find out what triggered the explosion. galaxy M33.

Cosmic winds are often considered a detrimental factor in star-forming environments because they can blow away necessary gases. However, Cosmic rays could still make a small contribution to star formationespecially in very active worlds like M33.
“We saw cosmic winds driven by cosmic rays in the Milky Way and Andromeda galaxies, galaxies with low star formation rates that have never been seen before. A galaxy like M33” – said Dr. Fatemah Tabatabaei from the Institute of Basic Scientific Research in Iran.
They discovered a special mechanism: stars much larger than our Sun accelerate throughout their lives, eventually exploding as supernovae. Deadly cosmic rays are created when shock waves from these supernovae explode, accelerating particles to near the speed of light.
If there are enough such cosmic rays, pressure can be created to drive the winds to carry the gas needed to form stars.
So, many supernova explosions and supernova remnants in giant star formation complexes created cosmic rays – although born from the dead, but play a role in the birth of new worlds.
What factors trigger star formation from gas and dust clouds remains an important and interesting question for astronomers. “Solar system” a new world, where there is a chance of giving birth to planets, including habitable planets like Earth.
The research has just been published above Monthly Notices of the Royal Astronomical Society.
