Jellyfish Galaxy (JO204)


Detail: This galaxy located in the Sextans constellation is not interacting with another galaxy through mutual gravitation like the Jellyfish Galaxy posted on July 4, 2024.

Intergalactic hot gas fills the spaces between galaxies in a galaxy cluster. When a galaxy moves through this intergalactic gas, it experiences intense pressure, causing the gas within the galaxy to be stripped away. The galaxy's blueish jellyfish tentacle-like structure is thought to have formed when its disk gas was stripped away in this manner. Credit: NAOJ
