SCIENTISTS are hoping to receive a message from aliens on August 22 at 10pm BST (5pm ET).
Astronomers from Stanford University beamed a message into space 40 years and think tomorrow is the earliest date that they can expect a reply.

Professors Masaki Morimoto and Hisashi Hirabayashi sent out their original message on August 15, 1983.
They blasted 13 drawings in radio wave form to a star called Altair.
Altair is about 16.7 light-years away from our planet.
The hope was that any intelligent life existing on exoplanets around that star would receive the message and send one back.
Morimoto and Hirabayashi made sure the 13 drawings blasted into the cosmos briefly explained the history of life on Earth.
This included an explanation of the structure of DNA.
According to a popular Japanese newspaper, tomorrow night, a team will use the Japan Aerospace Exploration Agency’s (JAXA) antenna to search the sky for a reply.
They’ll listen out for any unusual radio signals for around an hour, hoping to spot a similar message to the one that was sent.
No response doesn’t necessarily mean that the original message has failed.
The scientists may need to wait even longer to get a reply, if one is even being sent.
Proof of alien life has never been found and whether aliens exist is a hot topic of debate among the scientific community.
Nasa astronaut Stan Love previously discussed aliens with The U.S. Sun and explained why he thinks they haven’t visited us yet.
Despite Nasa now officially investigating unexplained UFO sightings, Love doesn’t believe intelligent aliens have come to take a look at humans just yet.
He thinks there could be intelligent aliens out in space bu that they just don’t want to visit us.
Love told The U.S. Sun: “You could imagine intelligent life that just doesn’t care about technology and is just perfectly happy to stay home and doesn’t feel like they need to build starships.”
