Alien hunters have did not contact ET as they’ve tuned into mistaken channel
Alien hunters reckon they’ve did not make radio contact with ET as a result of they’ve been tuned into the mistaken channel.
They suppose they could have been lacking out extraterrestrial messages as a result of they’ve been scouring too excessive frequencies. Now they plan to deal with decrease radio frequencies within the hope they may lastly make contact.
Astrophysicist Owen Johnson, from Trinity College Dublin, stated earlier makes an attempt had solely used increased frequencies regardless of on a regular basis providers similar to air visitors management, marine emergency broadcasting and FM radio stations utilizing low-frequency radiation on Earth.

Researchers in two groups primarily based in Ireland and Sweden are actually scanning decrease frequencies. If each choose up the identical sign then it suggests it comes from outdoors Earth.
“I have no doubt that many wondrous things will be found,” Owen informed analysis web site The Conversation. “And if we’re lucky we may reap the biggest reward of all – some company in the cosmos.”
He stated the query “is there life beyond Earth” had turn into “one of many hardest to reply in science.”

“Despite the seemingly boundless expanse of the universe which implies there’s potential for abundant life the vast distances between stars render the search akin to locating a needle in a cosmic haystack,” he stated.
He stated the Search for Extraterrestrial Intelligence – aka Seti – was devoted to discovering aliens by trying to find uncommon indicators dubbed technosignatures. But 60 years of searches have to date come up brief.
Owen stated he hoped to vary that by investigating a beforehand unexplored vary of frequencies. Previous technosignature searches included solely the band of radio frequencies above 600 MHz leaving decrease ones “virtually unexplored.”

That is as a result of decrease radio waves have much less power making them more durable to detect. Telescopes that function at these frequencies have solely not too long ago been developed.
Owen’s staff used two of the world’s most delicate low-frequency telescopes working at 110 and 190 MHz – to check 44 planets orbiting stars than the Sun recognized by NASA’s Transiting Exoplanet Survey Satellite.
The telescopes are so delicate they may detect a cellphone name midway throughout the Solar System. That made sifting by information for ET messages tough.
So far he has discovered zero indicators he believes hail from aliens. But he added: “We have only just started – and there are likely to be an enormous number of Earth-like planets out there.”
“We’re only at the start of a long journey.”
