Strange space object sending out ULF radio emissions
Torrance Hodgson, ICRAR/Curtin University
As you can imagine, studying radio frequencies from 340 million lightyears away presents its own special set of challenges. However, they’ve been able to develop a working theory of where it came from: supermassive blackholes that created “powerful jets of plasma” about two billion years ago.
“We’ve had to undertake some cosmic archeology to understand the ancient background story of the jellyfish,” said Hodgson in the press release. “This plasma faded, went quiet, and lay dormant,” Hodgson said. “Then quite recently, two things happened — the plasma started mixing at the same time as very gentle shock waves passed through the system. This has briefly reignited the plasma, lighting up the jellyfish and its tentacles for us to see.”
The Right Tool for the Job
Hopefully, we won’t have to wait long until researchers discover more about the cosmic jellyfish since construction on the new Square Kilometre Array (SKA) has begun. Researchers anticipate that the radio telescope will give us a far better look at the object.
“The SKA will be thousands of times more sensitive and have much better resolution than the MWA, so there may be many other mysterious radio jellyfish waiting to be discovered once its operation,” said professor Melanie Johnston-Hollitt, the paper’s co-author and Hodgson’s supervisor, in a press release.
The radio telescope will also give researchers a look at some of the first galaxies to have ever emerged in the universe. It’d be cool, though, if they discovered a cosmic shark or whale to join USS Jellyfish in our space aquarium.
