At the center of an ideal planetary system is an orange dwarf aptly named HD 110067. There are six planets orbiting it, each wandering in harmony with its neighboring worlds.
As scientists point out, an almost perfect “chain” of orbital resonances is extremely rare in space. This suggests that the system has been stable since its formation, about a billion years ago. The system itself has become the apple of astronomers’ eyes. However, its uniqueness does not lie solely in ideal mathematical proportions.
Scientists from the SETI Institute believe that this extraordinary system has created ideal conditions for the emergence of life and its evolution.
Specialists believe that the mentioned planetary system is extremely intriguing, especially when it comes to searching for life there. Therefore, it was searched thoroughly in the hope of finding radio signals that could provide evidence of a past or present civilization.
If the Earth is used as a model in the search for techsignatures, we also need to take into account the propagation of radio signals known to us – they propagate over a distance of about 100 light years. Therefore, potential signals reaching us from an ideal system are at the limit of detection.

There are six different worlds smaller than Neptune in this system. It is believed that liquid water may exist on the surface of some of them, which is extremely important in the context of the search for life as we know it.
To explore alien worlds, SETI scientists analyzed archival data from the Green Bank Telescope looking for techsignatures. They took cues from Earth’s technology to search for appropriate wavelengths and signal patterns.
Unfortunately, the research did not find any signals indicating the existence of an advanced civilization in this system. However, astronomers do not give up and say that they will return to this system when more accurate measuring instruments appear.
– Although we did not find any signals as a result of this search, we expect to return to this system and others like it in the future with increasingly sensitive and diverse search methods. This unusual system remains an interesting target for future searches for technosignatures, the scientists write in their paper.
The research results were published in a scientific journal Research Notes of the AAS.
