Orion, the Hunter was known for killing animals and now, scientists says that The Great Orion Nebula also does the same thing to young worlds forming near it.
Based on observation gathered from the radio telescopes at the Atacam Large Millimeter/ submillimeter Array (ALMA) in northern Chile, the giant include hot, young stars embedded in the gas cloud that blast any young planets and the associated debris that surrounds nearby baby stars.
The new data reveal that these newborn stars and their forming planets, ones located within 0.1 light-years (about 600 billion miles) of one of these fast and angry-type stars are doomed to have their blanket of dust and gas blown away in just a few million years, therefore, shutting down nearby planetary formation.
Astronomers believe that it is exactly what happens when new solar star systems are born or die.
Rita Mann, an astronomer in the National Research Council of Canada, Victoria, British Columbia, and lead author on the new study published in the Astrophysical Journal said that O-type stars are monstrous in size when compared to out sun, discharge tremendous amounts of ultraviolet radiation, and this can destroy young planets.
Through the use of ALMA, scientists studied the embryonic stars with planet-forming potential and, they found out that most planets simply vanished because of the intense glow of a neighboring massive star.
Orion Nebula provides the mean to create a new star. If such stars die, they provide the necessary elements to form a new generation of stars. However, the explosion could also kill newly-formed planets near the constellation.
“Taken together, our investigations with ALMA suggest that extreme [ultraviolet] regions are not just inhospitable, but they’re downright hazardous for planet formation. With enough distance, however, it’s possible to find a much more congenial environment,” said Mann.
If you are going to look toward the southern sky on any clear evening, you will find the constellation, Orion, the Hunter shines the brightest.
There is a distinguishing row of three equally brilliant stars that represents Orion’s belt, and four stars that surrounds the belt makes the shoulders and knees of the giant.
Hanging below Orion’s belt, are a line of fainter stars that can be seen by the naked eye — a hanging sword. An interesting example is made up of two dim stars and what looks to the eye like a fuzzy spot, which shines between them. This special “gleam” in the sword is a massive star factory 1,400 light-years distant otherwise known as the Great Orion Nebula.
