What if we could contact alien species? Even if we could, how would we communicate with them?

It's our job to try and we did it too. We've sent a message for aliens, in the universal language

This is the Golden Record (image 1), sent aboard Voyager spacecraft (image 2). It is a kind of time capsule, intended to communicate a story of our world to extraterrestrials

2/

The Voyager message is carried by a phonograph record, a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth

3/

The first diagram is the top view of the disk whose circumference's measurement is shown in terms of the standard unit we've set for aliens to use which is explained in the last diagram (hydrogen, bottom-right)

4/

Hydrogen was chosen because it's the most abundant element in the universe, so there's a really high chance that Aliens might be familiar with its properties

5/

The circle-in-the-rectangle is the first thing Aliens will see if they manage to decode everything correctly

6/

The diagram with lines originating from a common point comes originally from the Pioneer spacecraft. It shows the location of our Sun (Sun being the center) with respect to Pulsars near us

7/

This is the original diagram from the Pioneer spacecraft. One more common thing is the Hydrogen reference.
Humans are also shown with spacecraft's dish to scale

Following are some of the images that Aliens will see (in order of their appearance)

1. Calibration circle

The record's cover is aluminium and electroplated upon it is an ultra-pure sample of the isotope uranium-238. Uranium-238 has a half-life of 4.468 billion years. The records also had the inscription "To the makers of music – all worlds, all times" hand-etched on its surface

14/

The following is a listing of some of the sounds electronically placed onboard the Voyager 1 and 2 spacecraft

Music of The Spheres, Volcanoes, Earthquake, Thunder, Mud Pots, Footsteps, Heartbeat, Laughter, F-111 Flyby, Saturn 5 Lift-off, Herding Sheep, Blacksmith, Sawing

15/

The record also carries music from all parts of the world. The music from India was, raga, "Jaat Kahan Ho," sung by Surshri Kesar Bai Kerkar. Plays at 3:30

16/

The Golden Record also carries greetings to the Universe in 55 Different Languages. This being the one from India

"धरती के वासियों की ओर से नमस्कार" (Hello from the people of the earth)

17/

And this was all done with the technology before the year 1977.

Such a feat of humanity to send this much data with so much innovation that too with a possibility of it to be understood by Aliens

18/

The fact that there are chances of Alien life, that too intelligent, discovering our message in the vastness of our Universe, makes me feel much more alive, and humble
