Mysterious ‘alien’ signal came from Earth-like star system, scientist says

A mysterious signal sent to Earth from space known as “Wow!” the signal apparently came from a star very similar to our own Sun according to an astronomer studying the message

NASA: Former chief scientist discusses extraterrestrial life

Humans have been searching for signs of extraterrestrial life for many years.

From signals from space to potential sightings of unidentified flying objects (UFOs) in the sky, humanity’s curiosity has sought to find an answer to the question: are we alone?

One of the strangest incidents occurred in 1977 when an unexpected radio signal was detected which some believe could have come from an alien civilization.

Known as “Wow!” signal, the minute-long burst of radio energy was received on August 15, 1977, and baffled scientists.

The signal’s name came after stunned astronomer Jerry Ehman wrote the words next to a printout of the data.

The “Wow!” the signal was 20 times stronger than the average background emissions.

It is still considered one of the best signals captured by SETI telescopes.

The meaning of the message and its exact provenance remain unknown, but researchers surveying the skies for signs of extraterrestrial life have long speculated that this may have been Earth’s first contact with another form of life.

And now, 45 years after the message was spotted, there may finally be an explanation of where it came from.

Alberto Caballero is an astronomer who believes he has found the source of the signal.

He’s isolated a star that’s about the same size as our Sun where he thinks the signal came from.

Caballero undertook the arduous task of combing through the images collected by the European Space Agency’s Gaia mission.

The mission used a billion-pixel camera to capture images of our galaxy in incredible detail.

The astronomer narrowed down the search to two areas where the signal may be coming from.






The researchers speculated whether the “Wow!” the signal was a message from a distant alien civilization

He examined every star in both areas for K-type star systems that are considered hospitable to life.

He also looked at G-type stars that are similar to our own Sun.

One of the potential sources has been identified due to its similarities to the Sun.

Listed as 2MASS 19281982-2640123, the star is close to ours in size and energy output.

The star is located 1,800 light-years from Earth and has a solar analogue that makes it the most likely candidate region for an extraterrestrial signal.

Talk to Live Science Caballero concluded that the search for the signal is also a search “for life as we know it”.

However, the time it would take for the signal to reach Earth means more research needs to be done.

It is believed that a signal sent from such a great distance would take centuries to reach us.

No planets have yet been detected orbiting the star, but the discovery could be the first step in humanity’s search for other civilizations in space.

The next step would involve a more intensive search around the star and its solar system.

Any planets that could be found could then be searched for signs of life.

This could include things like traces of industrial pollution in their atmospheres or signs of beings with advanced technology.

The results were published May 6 in the International Journal of Astrobiology.
