The Wow Signal is a 72-second radio burst that was recorded in 1977 that has defied explanation for 40 years, leading many to believe it might be proof of intelligent life.

TRANSCRIPT:

SETI, or the Search for Extraterrestrial Intelligence, has access to telescopes all around the world, constantly scanning the sky for signals of alien communication.

Processing all of this information is a gargantuan task that would require a massive supercomputer that SETI can’t quite afford. So they came up with a brilliant idea.

It’s called SETI at home. It’s a program you can install on your computer that processes tiny parts of that data in the background.

Spreading that data across thousands of computers around the world, they’re able to crank through mountains of information, without the mountainous cost of a supercomputer.

But back in the 70’s none of that existed. Signals from space had to be printed out and processed by hand.

Which is exactly what astronomer Jerry Ehman was doing on August 18th, 1977. He was going over reams of printouts when he found a massive spike in a certain frequency of radio wave.

It was a spike 30 times higher than the background noise, and it was so noteworthy, he literally wrote “Wow” on the page.

It has since become known as the wow signal, and it’s still confusing scientists 40 years later.

The Big Ear went into operation in 1963 and was initially put to use on the Ohio Sky Survey, which catalogued nearly 20,000 sources of radio waves between 1965 and 1971.

Since it was on the ground, the telescope basically used the rotation of the Earth to scan across the sky.

When it measured a radio signal, they could infer by the time of day what direction the telescope was pointing and match that with visual sky surveys to figure out what star or galaxy it came from.

In 1956 on the grounds of Ohio Wesleyan University, construction crews broke ground on a massive telescope the size of three football fields to monitor the sky for radio signals from deep space.

It was officially known as the Ohio State University Radio Observatory, because it was actually run by Ohio State, but it was more well known by its nickname. The Big Ear.

The Big Ear went into operation in 1963 and was initially put to use on the Ohio Sky Survey, which catalogued nearly 20,000 sources of radio waves between 1965 and 1971.

Since it was on the ground, the telescope basically used the rotation of the Earth to scan across the sky.

When it measured a radio signal, they could infer by the time of day what direction the telescope was pointing and match that with visual sky surveys to figure out what star or galaxy it came from.

So a popular misconception with the wow signal is that 6EQUJ5 is some kind of alien code that we received but it’s actually just a measure of signal strength.

Ehrman and others immediately started pointing telescopes at the spot where the signal originated, which is in the constellation Sagittarius, but nothing has ever shown up.

So, it’s not a star or galaxy or pulsar or black hole because we’d pick up more signals from that location. As far as we know, and we’ve looked there a lot at this point, there’s nothing there.

At least, no cosmic body that would normally produce a radio stream like that.

But the mystery actually gets deeper. Because the frequency that this signal was found on was 1420 MHz. And if you were paying attention in last week’s video about the Voyager missions, 1420 mHz is the frequency that hydrogen atoms expel photons during hyperfine transitions.

(also known as 21-centimeter line or hydrogen line)

This same frequency was used by Carl Sagan and Frank Drake when creating the Pioneer and Voyager plaques as a way to communicate with an alien species should they ever come across the spacecraft.

Astronomers Detect 15 Signals From Mysterious Object In Distant Galaxy

While looking for signs of intelligent life in the universe, astronomers have detected 15 fast radio bursts from a distant galaxy.

These poorly understood phenomena are short pulses of radio emission, just milliseconds long, believed to be coming from rapidly spinning neutron stars or black holes in distant galaxies.

A less popular theory is that they’re signs of extremely powerful spacecraft from alien civilizations.

This particular fast radio burst (FRB), called FRB 121102, is of particular interest as it is the only known one to be repeating, something that astronomers can’t yet explain.




Earlier this month, astronomers using the Green Bank Telescope in West Virginia not only found 15 more bursts, but found them at a higher radio frequency than was ever observed before, the astronomers said in their findings published in The Astronomer’s Telegram.

It’s not surprising that we’ve found 15 more from this source; we’ve been detecting many of them over the past few years,” Paul Scholz, an astronomer who studies FRBs with the Dominion Radio Astrophysical Observatory in Penticton, B.C., said.

The one thing that’s unique about these [new ones] is that they are at a higher frequency than we’ve ever seen before.

Scholz, who was not involved with the new discovery, was with McGill University when he and a team of astronomers discovered FRB 121102 to be a repeater. In 2016, a McGill team was able to locate the source of the strange FRB.

At the time the signals left its host galaxy, Earth would have been two billion years old, less than half its current age. The only living things on the planet would have been single-celled organisms.

SOLVING THE MYSTERY

As though the object wasn’t strange enough, it also behaves like no other FRB. Typically, objects that emit similar signals, such as pulsars, do so in a smooth fashion across many frequencies. But that’s not the case with FRB 121102.

So it’s kind of perplexing,” Scholz said.

Scholz said that there could be reasons such as the signal being distorted between its source galaxy and Earth.

In the coming months, a new telescope in B.C. called the Canadian Hydrogen Intensity Mapping Experiment (CHIME) is expected to begin its research into FRBs, with the possibility of discovering several a day, something that Scholz is looking forward to seeing.

It’s a mystery that needs to be solved,” Scholz said.
