Active SETI (METI) to begin sending messages to "Proxima b" to initiate Alien contact.

Humans are finally making an all-out effort to reach aliens with some conversation starters by sending a transmission to Proxima b, the closest exoplanet neighbour to us. The novel plan is devised by scientists at San Francisco-based Active SETI (METI - Messaging Extra Terrestrial Intelligence) who want to beam signals to communicate with aliens instead of waiting for them to call.
Accordingly, METI researchers would like to make the process operational by the end of 2018 with a first message "Hello."

Laser or radio signals will be beamed to Proxima b  that orbits Proxima Centauri, around 4.25 light-years away. The project will beam repeated and intentional messages to the same planets for months and years from Earth. However, the content of the message will be carefully crafted. The METI team will plan the messages to make sure that the alien life forms can convert them.
For the project, METI will go on a fund raising move and hopes to raise around $1 million a year for running the transmitter.

Concerns over the messaging plan were raised by Mark Buchanan in a paper published in the Nature Physics journal. He argued that broadcasting messages into space amounts to just "searching for trouble". "We have almost zero idea of whether aliens are likely to be dangerous." he added.
Stephen Hawking, the famous physicist is also against trying to communicate with alien civilizations as he feels they may be more advanced than humans and is afraid such life forms may underrate humanity as weaklings and seek to conquer.
However, the move is also appreciated by many.
