A team of astronomers at the International Center for Radio Astronomy Research (ICRAR) detected a cosmic phenomenon that closely resembles jellyfish in space with the Murchison Widefield Array radio telescope, or MWA, which is located in Outback in Western Australia, jellyfish have been seen in a galaxy cluster known as Abell 2877.

The results of this monitoring were published in a research paper in The Astrophysical Journal, in its March 17 issue.

According to the press release issued by the International Center for Radio Astronomy Research, the lead author of the study, Dr. Torrance Hodgson, said that the team "observed the group of galaxies known as Abell 2877 for 12 hours at 5 radio frequencies between 87.5 and 215.5 MHz, then we looked at the data, and when we lowered the frequency We saw a ghostly jellyfish-like skeleton begin to appear. "

Dr. Hodgson added that the jellyfish rays are bright at regular FM radio frequencies, but at 200 MHz all emissions disappear from it, as no extra-galactic emission has been observed, so this very steep spectrum is difficult to interpret. Expression of Dr. Hodgson.

Cosmic effects and jellyfish pose

On tracking how this phenomenon was formed in cosmic space, Dr. Hodgson said, "We had to conduct some surveys and track cosmic traces to understand the story of the ancient background of space jellyfish."

"The information available to us indicates that, about two billion years ago, a handful of supermassive black holes from multiple galaxies released powerful beams of plasma, and these plasma faded, calmed down, and fell into hibernation," he added.

And recently, two things happened, the plasma started mixing at the same time as very thin shock waves passed by, and this briefly re-ignited the plasma, and the alien jellyfish and their tentacles lit so we could see them.

Although the diameter of the observed space jellyfish - which is more than a third of the diameter of the moon when observed from Earth - it can only be seen with low-frequency radio telescopes.

In this regard, the astronomer Hodgson says, "Most radio telescopes cannot achieve observations at this low level due to their design or location."

The importance of discovery

According to the statements of scientists in the statement issued by the International Center for Radio Astronomy Research, the importance of such a discovery of jellyfish opens up a way to answer basic questions about the universe, and scientists have already discovered in 2017 a galaxy similar to a jellyfish located in the clustering of galaxies Abell 267, away from the Earth by a distance Estimated at a billion years, it is the galaxy that astronomers are still researching its inception and formation.

On the other hand, the US Space Agency (NASA) broadcast, last October, pictures taken by the satellite "Juno" spacecraft highlighting colored explosions of electricity similar to lightning in the atmosphere of Jupiter, in the form of a jellyfish.

They often occur in the upper atmosphere of the Earth during thunderstorms.

Scientists predicted that other planets with lightning, such as Jupiter, would also produce these transitory luminous events.
