NASA’s Hubble Telescope captured this image of the “Jellyfish” galaxy. Although it looks a lot like an animal, the JW100 galaxy looks like this because of the celestial body’s gas flow, which appears to float like tentacles. From these tentacles stars are formed.
This is caused by a process called RAM (Ram Stripping Pressure), which is when galaxies encounter gas around clusters of galaxies. As they pass through the gas curtain, is They act like winds that blow dust from within the galaxy, creating these bright spots.
The filaments represent star formation under extreme conditions and could help astronomers better understand the star formation process in other parts of the universe.
Further in the same photo are two bright spots next to each other, looking like a traffic light (see below). Named IC 5338, it is the brightest galaxy in the cluster. As galaxies of this type grow, they consume smaller galaxies, causing them to have multiple nuclei.
