Strange radio waves from distant ‘jellyfish’ galaxy baffles scientists

Scientists are baffled by strange radio emissions coming from a distant galaxy cluster that is shaped like a giant jellyfish.

Images generated of the source of the strange sounds show it having a "head and tentacles".

Adding to the mystery is that the "cosmic jellyfish" only emits the lowest radio frequencies, and cannot be detected higher up the scale.

It is also enormous, and stretches across 1.2 million light-years. It is located in Abell 2877, a cluster of galaxies 340 million light-years from Earth.

Melanie Johnston-Hollitt, an astrophysicist at Curtin University in Perth, Australia said: “This is a source which is invisible to most of the radio telescopes that we have been using for the last 40 years."

Science News reports that Johnston-Hollitt’s colleague Torrance Hodgson discovered the "USS Jellyfish" while analysing data from the Murchison Widefield Array, a complex of radio telescopes in Australia that detect low-frequency radio.

The space boffins believe that two galaxies in the Abell 2877 cluster coincide with the brightest patches of radio waves in the USS Jellyfish’s head, and that they probably have supermassive black holes at their centers.

According to their estimations, they are at least 2 billion years old.

Earlier this week, scientists shared a new image of a supermassive black hole which conveys the true chaos of space.

The Event Horizon Telescope [EHT] team released its sharpest image yet of the cosmic wonder that shows the vortex of magnetic chaos surrounding it.

The first images of the M87 black hole which lies at the centre of the M87 galaxy some 55 million light years from Earth were released in 2019.

They displayed a bright ring-like structure with a dark central region described as the black hole's shadow.

Researchers observed images of magnetic fields at the black hole's edge, where some matter falls in.

Meanwhile, other matter is being blown into space in the form of bright, powerful jets that extend at least 5,000 light-years away, beyond the galaxy in which the black hole resides.

Using the same data as for their first image, the the EHT team and University College London (UCL) analysed polarised light around the black hole – light in which the waves are vibrating in one direction only.
