JWST unveils a cosmic jellyfish, offering clues to how galaxies evolved in the early universe

Using the James Webb Space Telescope, astronomers captured ESO 137-001, a jellyfish galaxy in the COSMOS field, showing trailing gas filaments stripped by ram pressure as it moves through a cluster. The image reveals blue, star-forming knots in the tails and places the system at about 8.5 billion years ago (roughly 5.3 billion years after the Big Bang), suggesting harsh cluster environments were already shaping galaxies earlier than thought; researchers plan further JWST studies to deepen understanding of galactic evolution.

"Hubble Captures Stunning Images of Aquarius Galaxy JO206"

The Hubble Space Telescope has captured an image of the jellyfish galaxy JO206 in the constellation Aquarius, showcasing a colorful star-forming disk surrounded by a pale, luminous cloud of dust. The tendrils of star formation trailing the galaxy are formed by the interaction between galaxies and the intra-cluster medium, providing astronomers with a unique opportunity to study star formation under extreme conditions. Surprisingly, Hubble revealed that there are no significant differences in star formation between the galaxy's main disk and its tentacles, suggesting that the environment has only a minor influence on the formation of newly formed stars.

Jellyfish Galaxies and Rare 'Facehugger' Jellyfish Captured by Hubble and ROV

The Hubble Space Telescope has released its final image in a series of jellyfish galaxies, showcasing JO206 in the Aquarius constellation. These galaxies have tendrils of star formation caused by interaction with intra-cluster medium in galaxy clusters. Hubble’s findings suggest that environmental conditions minimally affect star formation, as evident from the similarities between star formations in the galaxy’s main disc and its tendrils.
