Aliens: Study reveals 36 alien civilizations may be trying to contact Earth
While scientists are exploring ways on how to search for alien life, there is also that possibility that aliens may be trying to contact us as well. A study reveals that there may be more aliens trying to get in touch with Earth, but we may not be prepared for such an occurrence.
Express reports that a study conducted by researchers from the University of Nottingham found that there may be alien civilizations that are trying to reach out to Earth through the radio signals being sent all throughout the universe. The study focused on the chances of intelligent life evolving in other planets based on the evolution seen on Earth. The research found that aliens that can send radio signals evolve at an average of 17,000 light-years from each other.
This would imply that up to 36 alien civilizations not only exist in the Milky Way but are also trying to contact Earth.
However, the researchers believe that Earth is not yet prepared or equipped to receive these signals coming from those civilizations. They reasoned that we are not yet technologically advanced to be able to receive and respond to these signals. According to University of Nottingham astrophysicist Professor Christopher Conselice, “I think it is extremely important and exciting because for the first time we really have an estimate for this number of active, intelligent, communicating civilizations that we potentially could contact and find out there is other life in the universe…”
Along with the possibility of other intelligent beings in the universe, scientists were previously able to find an exoplanet and an accompanying star that looks uncannily like the Earth and the Sun. Scientists from the Max Planck Institute for Solar System Research in Germany made the discovery, formally referring to the exoplanet as KOI-456.04 and, along with its star which is referred to as Kepler-160, could be found 3,000 light-years away from Earth, which is extremely far away.
Because this exoplanet is believed to be strikingly similar to Earth, scientists are then thinking about the possibility of finding life on the said exoplanet.
However, despite the possibility of finding life, there are conditions in which life may not be able to survive. Because Kepler-160 belongs to the red dwarf classification of stars, these kinds of stars are believed to produce radiation that could melt any planet or debris that gets too close.
