The Hubble Space Telescope has discovered a jellyfish galaxy in the constellation Aquarius. Attracting astronomers and space enthusiasts alike, the telescope has revealed a mesmerizing sight known as the jellyfish galaxy. Named JO206, it resembles an elegant creature of the ocean. This jellyfish galaxy’s captivating appearance is due to the graceful tendrils of gas and dust extending from its core deep into the universe.
Dr. Marco Gullieuszik, together with a team of colleagues from INAF-Osservatorio Astronomy Padova, emphasized the importance of understanding the physical conditions that lead to the formation of stars and, conversely, that make the process Their formation is stopped.
“Understanding the physical conditions that lead to the formation of new stars and conversely stop star formation is central to astrophysics.”.
In this complex cosmic ballet of galaxies, Dr. Gullieuszik and co-authors discovered a surprising number of star-forming clusters. Notably, more than 3,700 clusters were observed in disks, while 1,200 clusters materialized in extraterrestrial regions, and an additional 1,200 clusters were discovered in graceful tails extending from the last periods. this galaxy.
To their surprise, the researchers discovered that star formation in the disks of jellyfish galaxies and their fasciculate tendrils was not significantly different.
“Surprisingly, Hubble revealed that there are no notable differences between star formation in the disk of jellyfish galaxies and star formation in their tentacles, which suggests the environment of stars newly formed have only a small influence on their formation.” they said.
These photographic evidences suggest that the environment around newly formed stars plays a small role in influencing their birth. The team commented that future studies focusing on the mass, age, and star formation activity of these clusters, along with examining trends and slopes as they move away from host galaxies, will sheds light on the differences between these clusters and resident galaxies. in undisturbed galaxies. This research effort aims to elucidate the impact of ram pressure on the interstellar medium and the impact of the environment on star formation.
More information about jellyfish galaxy
The birth of jellyfish galaxies occurs when a smaller galaxy approaches the periphery of a larger galaxy. The enormous gravitational force generated by the giant host galaxy ruthlessly stripped gas and dust from its tiny partner, leaving behind a graceful, elongated tail. This process favors the formation of new stars in smaller galaxies, as stripped materials recombine to create stellar nurseries.
Jellyfish galaxies, with their trailing tails of gas and dust, represent a fascinating class of galactic entities. These extraordinary formations are relatively rare but are gradually becoming more prominent as the universe continues to develop.
Jellyfish galaxies are captivating testament to the ongoing evolution of galaxies. They give us a fascinating glimpse into the turbulent and chaotic past of these cosmic entities. Furthermore, they serve as guides, providing invaluable clues about the future, as galaxies continually merge and engage in complex interactions with each other.
