In the depths of the universe: Hubble photographed the Medusa galaxy - voila! technology


Not in water, but 800 million light-years away, the galaxy JW 100 caught the eye of the space telescope for the unusual appearance of a galaxy with jellyfish-like arms - which are also an unusual way

Hubble caught a jellyfish.

Well, not quite a jellyfish from the sea, but a galaxy that looks like one.

Located 800 million light-years away in the Pegasus system, the galaxy JW 100 contains streams of gas and stardust that look like the cruising arms of water jellyfish on Earth, and it is a beautiful sight, which has also led astronomers to give it the affectionate name "Jellyfish".

The arms are formed as a result of a process of cosmic "peeling" in which galaxies encounter gas clusters, and their gravity simply "peels" pieces of the cluster under pressure, in thin strips resembling the arms of a jellyfish.

Next to JW 100 you can see in the upper left corner of the amazing image taken by the Hubble Space Telescope, two bright discs of light - this is the core of the galaxy IC 5338, the brightest cluster.

It is an elliptical galaxy with an extended halo, a type of galaxy known as cD.

These are galaxies that grow by "swallowing" smaller galaxies, so it is not uncommon to see ones with a double nucleus, because the process of merging the nuclei takes time.

The bright fringes are clusters of stars.

This observation used Hubble's Wide Field Camera 3 and its capabilities, and is part of a series of observations that follow Medusa galaxies, due to the unusual conditions they create for star formation.
