Current SightingsStrange, Distant Space Object Is Sending Out Ultra-Low Frequency Radio Signals Posted on March 30, 2021 by Administrator Researchers have detected ultra-low radio frequencies being emitted from a jellyfish-shaped object in a distant galaxy cluster. The mysterious object is located 340 million lightyears from Earth in the galaxy cluster Abell 2877, according to ScienceNews. The researchers behind a paper published in The Astrophysical Journal say they used the Murchison Widefield Array (MWA) radio telescope in western Australia to discover the ultra-low radio frequencies — and its distinct shape.
