Have we Received an
Alien Message from Someone on an Unknown Planet
around a Sun-Like Star in the Sagittarius Constellation?
maybe someone there
sent us a message long ago
and they are waiting for a reply.
When it comes
to exploring the cosmos,
anything is possible...
Big Ear was never the world's biggest radio telescope, nor its most sensitive.
But Big Ear
nevertheless made one of the most famous observations in the history
of astronomy, one that till this day has never been explained.
And on Aug. 15, 1977, it found one:
The team quickly ruled out a terrestrial origin or a broadcast from a satellite.
Nevertheless, the signal
was so powerful and unusual that Jerry Ehman, the astronomer
who analyzed the data print out, annotated the signal with the word
The Big Ear team
continued to observe the same part of the sky, as have others, but
the 'Wow! signal' never returned. Nor has anything like it been
observed in any other part of the sky.
To this day, the 'Wow!
signal' remains unexplained and unrepeated.
First, some background.
Gaia's new star map has significantly improved our understanding of the galaxy and the stars within it and this gave amateur astronomer Alberto Caballero an idea.
North American Astrophysical Observatory
By Sun-like, he means,
The search returned just one candidate.
This star sits in the constellation of Sagittarius at a distance of 1800 light-years.
Of course, Caballero's work does not mean that 2MASS 19281982-2640123 must have been the source... He points out that there are many stars in that region of the sky that are too dim to be included in the catalog.
One of these could be the
These match the Sun's temperature but data about their luminosity and radius is currently incomplete. So future data releases from Gaia and other mapping projects might yet reveal them as matches.
Caballero says an obvious goal would be to look for signs of exoplanets orbiting this star.
In the meantime, astronomers might amuse themselves by finding a friendlier name for 2MASS 19281982-2640123.
Perhaps during a round of
golf on the course that now sits on the site of the Big Ear radio
