This week’s image from the Hubble Space Telescope shows an unusual type of galaxy named for its watery, jellyfish-like appearance.
The Jellyfish Galaxy JO206 is seen in an image taken with Hubble’s Wide Field Camera 3 instrument, 700 million light-years away, in the constellation Aquarius. sea, and are formed through a process called ram pressure stripping.
And when a galaxy moves through a galaxy cluster, it is not only moving through the vastness of space, but through diffuse clouds of plasma gas called the center of the inner cluster, which is much hotter than the surrounding space outside the cluster.
As the galaxy moves through this medium, it creates clouds, which push gas out of the galaxy and cause long tails to form behind the main body of the galaxy, the tails of which are the tendrils of the jellyfish galaxy.
Hubble has previously captured a number of other jellyfish galaxies, such as JO201 and JW100. Hubble is often used to study these galaxies because of the high rates of star formation in their tails. Astronomers want to understand how star formation can vary when it occurs far from the center of a galaxy, but it turns out The process looks very similar, whether it occurs at the center of the jellyfish galaxy or at the tips of their tails.
“The Jellyfish Probes give astronomers a unique opportunity to study star formation under extreme conditions, far from the influence of the galaxy’s main disk,” the Hubble scientists said. “Surprisingly, Hubble revealed that there are no striking differences between star formation in the jellyfish disks and the formation of The stars are in their tentacles, indicating that the environment of newly forming stars has little effect on their formation.”
