Scientists have been struggling with the mystery of powerful alien radio signals in space for over 10 years.
Foreign astronomers, using the ASKAP (Australian Square Kilometre Array Pathfinder) radio telescope, were able to accurately determine their position and measure the distance to a source of single FRB radio bursts known as “alien radio signals.”
According to Australian researcher Keith Bannister, the new data is a huge breakthrough, as this information had been highly anticipating the detection of the first such signals.
Mysterious alien radio signals
Mysterious flashes were accidentally discovered in 2007 by Bannister and his colleagues. At that time, they were observing radio pulsars with the help of the Parks telescope (Australia).
In the following years, scientists have discovered about 30 such bursts. According to the researchers, the signals were artificial. They could even serve as flashes of extraterrestrial civilizations because of the inexplicable periodicity in their structure.
All signals had high power. They were also too far from their sources. Some astronomers have suggested that bursts are born during the merger of neutron stars or other compact objects, becoming a black hole. In 2017, using Parks, researchers recorded new flashes at the same point, which contradicted this theory. “Aliens Signals” have become more mysterious.
Source of these signals
Later, astronomers localized the source of this outbreak. It was an invisible dwarf galaxy in the constellation Auriga, which is three billion light-years. In that case, it was not possible to find out the nature of the bursts.
Later, scientists sent all the ASKAP antennas to one sector of the sky in the hope of catching a new surge. As a result, in September 2018, watching one of the flares, experts realized that it comes from the large “dead” elliptical galaxy DES J2144-4054. The latter is located in the constellation Heron at a distance of 3.6 billion light years from Earth.
It was possible to clarify the position of the signal due to other telescopes: VLT and Gemini. It also emerged that the sources of repetitive and single signals may differ. For example, the first flash is on the outskirts of the galaxy, while the second one comes from the central part of the dwarf galaxy, where a lot of new stars are born.
It is still unknown what exactly gave rise to these outbreaks, the work in this area is ongoing.
