From the depths of outer space, earth received its first message. The Big Ear radio telescope at Ohio State University picked up a strong 72-second signal from the constellation Sagittarius, detected by astronomer Jerry R. Ehman. Circling the frequency code of the signal, 6EQUJ5, on the computer printout Ehman wrote, “WOW!” Also known as “The WOW! Signal.”
This powerful blast of radio waves had arrived from the direction of the constellation Sagittarius and bore all the hallmarks of extraterrestrial origin. The incident came to be known as the ‘Wow! Signal’ and has since been used to support the argument to search for alien civilisations. One of the reasons why this signal has been such a fixation among science enthusiasts is because the Big Ear radio telescope was built to function on a frequency aliens would communicate. The 1.42 GHz radio frequency is naturally emitted by hydrogen. And since hydrogen is the most common element in our universe, it was considered highly likely that intelligent life outside of the earth would be familiar with it.
The Wow Signal was recorded for 72 seconds, an incoming signal’s maximum duration of detection. As the earth rotated, the telescope’s antenna swept through the night sky, listening for signals coming from various directions. The antenna was pointed at the same angle for several days and then titled slightly so that it could scan the next band of sky around the earth. For an alien to contact humans, they would have to transmit their signals at frequencies they know will be heard.
In May 2015, a team of researchers using a Russian radio telescope spotted a strong radio signal coming from the vicinity of the sunlike star HD 164595, which lies 94 light-years away from Earth. The signal is consistent with something one alien civilization might have send out, the signal may also have resulted from a natural celestial event or terrestrial interference of some sort. The same team of astronomers that discovered the 2015 signal apparently studied the HD 164595 system 39 different times but only made one detection. The detection team has not yet published a study of its findings.
The Oumuamua
The space anomaly named Oumuamua Hawaiian for “a messenger from afar arriving first”. The astronomer at the University of Hawaii who first detected it, knew immediately from its speed that he was looking at something new to physics. This was no ordinary comet or asteroid, it was an interstellar visitor from a great distant, unidentified solar system – the first to have ever been found.
The object was rusty red, shaped like a cigar, and tumbling uncontrollably. Asteroids are mostly rocky because they formed closer to the sun, where the heat melted away any ice. Comets are mostly made of ice because they formed farther out, safe from the glare.
First it was a mysterious acceleration away from the Sun, which was hard to reconcile with many ideas about what it might have been made of. Than the second was its peculiar shape , some estimates it was 10 times as long as it was wide.
Astronomers used computer modeling to explore possible explanations for the mysterious acceleration, including potential effects of solar radiation, drag-like forces, and interaction with solar wind, the charged particles emitted by the sun. None of them fit.
Galactic Federation
A former head of Israel‘s military space program claims that extraterrestrials have made contact with officials in the United States and Israel over the years, but the aliens won’t come out in public because they worry people will freak out.
Humanity isn’t ready,” professor and retired Israeli general Haim Eshed said during an interview with the paper Yediot Aharonot. Allso the paper takes note of Eshed as him saying that aliens are already among us on Earth, and that several species have formed a “Galactic Federation” He also suggested that the U.S. and Israel have been collaborating with aliens on space travel for years, and that U.S. President Donald Trump was “on the verge” of revealing their existence.
Eshed told the paper that he was coming out with his claims now because academia has become more open to such ideas.
“If I had come up with what I’m saying today five years ago, I would have been hospitalized,” he said. “Today, they’re already talking differently. I have nothing to lose. I’ve received my degrees and awards. I am respected in universities abroad, where the trend is also changing.”
