Hey, Vsauce. Michael here. But what could be

out there? The likelihood of extraterrestrial intelligence

has been the subject of an equation and the current lack

of any communication with aliens the subject

of a paradox. But here's a different question. If we were to hear

from intelligent life beyond earth, what would really

has ever officially adopted a post-detection policy.

And when asked how they would deal with a confirmed message from

the United Nations Office for Outer Space Affairs

simply said that their job does not include any issues regarding

we prepare for, and anticipate our species encountering one from beyond

earth, is important and illuminating even though

contamination is a concern that a man-made object returning from space

could carry with it undiscovered alien life forms, especially

life on earth. This was a serious concern

dealt by serious people when we first sent

Michael Collins and Buzz Aldrin returned from the lunar surface,

they didn't immediately hugged their families and join a public parade.

Instead, they were sealed up in biological isolation garments and flown

to a quarantine facility to be locked away for three weeks,

By Apollo 15 the practice was discontinued but forward contamination

been a real concern. When NASA sent the Galileo spacecraft to serve a Jupiter

but there was a problem. It had never been

sterilized. Because life, even liquid water, could exist

on these moons, NASA made the decision to avoid contaminating an

alien biosphere and the mission was over, steered Galileo

into Jupiter, where it burned up and was destroyed,

on board. So protocols and decisions have been officially made in

under the assumption that aliens might exist.

When it comes to actually hearing from aliens,

receiving a message from technologically advanced life forms,

the search for extraterrestrial intelligence, are other ones actively

are prepared. The SETI committee of the International Academy of Astronautics

created a declaration of principles concerning activities following

the detection of extraterrestrial intelligence.

No government has officially adopted any of its recommendations,

but if something were to happen, it would likely be the first place

authorities went. It's one of the only handbooks

they'd have. Seth Shostack explained the philosophy in atmosphere at SETI,

predicting that because verifying a signal is slow,

and the media are fast, you will be media blasted about a possible detection

days before the people who find it are certain it's for real.

In the midst of rampant media speculation,

elation and panic on the part of the public,

the most likely string of official events,

after the discovery of a message from extraterrestrial life,

would follow SETI recommendations. First of all,

the individual or team who discovered the message

would continue to assess the credibility of the message

and alert all parties to SETI's declaration. Next,

once they were certain the message was real, the Central

Bureau for Astronomical Telegrams would be alerted,

so as to inform observers all over the world.

They would also inform the secretary-general

of the United Nations, because article 11

of the treaty on principles governing the activities of states in the exploration

and use of outer space, including the Moon and other bodies

says they should. The first official news

we got, the public, would likely be in terms

of the Rio Scale. First presented to the International

Astronautical Congress, the Rio Scale measures

the significance of consequences of evidence of extraterrestrial life,

making it a likely tool to be used, because it neatly manages public

reaction. There's a great online calculator you can play with to see how

works. It takes into account the credibility of the message

on a scale from believed extraterrestrial origin to

what type of message it is, for instance, is it uninterpretable

or clearly for us and how far away it is.

Is it extra galactic or near enough that we could respond and hear back

within the length of a human lifetime. Seth Shostak and Ivan Almar

applied the Rio scale to fictional and historical

events. It's a great way to get a feel for how the Rio scale will affect

authorities use when reporting on an extraterrestrial

message. They considered the Moon monolith,

In the movie Independence Day, the initial unidentified signal would be
