Most of the massive stars in the Universe originated in huge star clusters. The so-called clusters are the blocks that form the galaxies, however, their creation from the dense molecular clouds is little known.
Recently, astronomers created an image that shows space fireworks in the star cluster G286.21 + 0.17, located in the Milky Way in the Carina region, about 8,000 light years away.
“This image shows stars at various stages of formation within this single cluster,” said scientist Yu Cheng, of the University of Virginia, USA.
Superbe image de l’amas G286.21 + 0.17 in Carène, at ~ 8000 al.
750 radio observations of ALMA et 9 images Hubble infrared montrent les mouvements de gaz turbulents tombant in l’amas, formant les noyaux denses qué créent finalement des étoiles.https://t.co/ltrb4sTaEn pic.twitter.com/6slOxwoNdW

Beautiful image of the G286.21 + 0.17 star cluster in the Carina region about 8,000 light years away.
The scientists made a mosaic, made up of multiple wavelengths, made from more than 750 individual observations from the ALMA telescope and nine infrared images from the Hubble Space Telescope.
“We see competing forces at work: gravity and turbulence of the cloud, on one side, and stellar winds and radiation pressure from young stars, on the other. This process forms the region. It is incredible to think that our Sun and planets were once part of a similar cosmic dance, “commented study co-author and principal researcher Jonathan Tan, from Chalmers University in Sweden and the University of Virginia, writes Tech Explorist portal.
The telescope observed the movements of turbulent gas falling into the cluster and forming dense nuclei from which individual stars are later born.
