Astronomers revealed an image of the galaxy called JO206, showing a colorful star-forming disk surrounded by a faint cloud of dust.
The NASA/ESA Hubble Space Telescope captured this image of the Jellyfish galaxy JO206, which highlights a handful of bright stars in the foreground with diffraction ripples (a diffraction or diffraction of light) intersected against an inky black background below the image.
The galaxy has been called the “Jellyfish Galaxy” because of its resemblance to the aquatic organism of the same name.
In the lower right of this image, long tendrils of bright star formation trace JO206’s disk, as do the limbs of a jellyfish behind it.
The tendrils of jellyfish galaxies are formed by the interaction between galaxies and the medium within the cluster, a weak, extremely hot plasma that pervades galaxy clusters.
As galaxies move through galaxy clusters, they collide with the inner cluster medium, which removes gas from the galaxies and draws it into the long tendrils of star formation.
Jellyfish galaxies give astronomers a unique opportunity to study star formation under extreme conditions, far from the influence of the galaxy’s main disk.
Surprisingly, Hubble revealed that there were no striking differences between star formation in the disks of jellyfish galaxies and star formation in the fringes, indicating that the environment of newly formed stars has only a slight influence on their formation. (Russia Today)
