Astronomers have discovered this group located in the region of the Milky Way Galaxy, relatively close to the Solar System. This region contains a great chemical wealth and many of the supernovae that occur there have helped shape the chemical composition of the Milky Way.
Discoveries about our galaxy continue. The European Space Agency (ESA) seeks to map our galactic region as accurately as possible. Astronomers are using the Gaia telescope to scan the sky, to get better details on the meandering of the Milky Way. Recently they have been able to observe A new area in our immediate neighborhood. An area that was thought to be empty and already slated to be filled with stars is about to erupt.
Astronomers at the European Space Agency are not at the end of their surprises. This area was named Cepheus spur, or Stimulate Cepheus in French. It is located between the arm of Orion that includes our solar system and the constellation Perseus. Next door on the galactic scale, infinitely far away on a human scale. This region lies between the arms of the Milky Way, and is marked by the belt shape.
According to astronomers, It is studded with blue stars called OB stars. It can reach its mass Three times from our sun. They Six times hotter By comparison, it emits blue waves. These stars are in between Rarer, bigger, hotter, and shorter life. This is why supernovae, the explosion of stars at the end of their lives, are so frequent in this region, and so violent.
Rich blue stars, whose explosions enriched the galaxy’s chemical composition
The discovery is delighted by the European Space Agency, especially because of the rarity and influence of this type of star on the chemical diversity of galaxies. The team was able to prove this This region contains most of the chemical elements found in our galaxy. “ OB stars are rare, in a galaxy of 400 billion stars, there can be fewer than 200,000. […]It was because of such long-dead stars that the geochemistry of our planet was complex enough for biochemistry to occur.. Said Michelangelo Pantaleoni Gonzalez, co-author of the study.
This star cluster is located in An area we thought was empty. The distance of this region from our system was estimated using a detection technique called star parallax. “After months of work, we saw this beautiful card for the first time. I felt like an explorer, making the first accurate maps of our world, but at a different scale. I felt so humbled and small when I saw how vast our stellar neighborhood was,” Michelangelo Pantaloni Gonzalez concluded, moving.
