Humanity s Messag to the Cosmos

 Did you know Voyager 1 is currently 24.97 billion kilometers away from Earth? Yes, that's right! Launched in September 1977, this remarkable space probe has been traveling for over 48 years. To grasp how vast that distance is, consider this: if someone started counting one number per second, it would take them 792 years to reach 24.97 billion!






 A Golden Record for the Stars


Voyager 1 carries a "Golden Record"—a time capsule with greetings and sounds in multiple languages, including Urdu and Punjabi. This record, made with special material, is designed to survive for millions of years. Its purpose? If the spacecraft ever encounters extraterrestrial life, those beings might understand that humans exist elsewhere in the universe.




In addition to audio greetings, the record also includes a map showing Earth’s location in the Milky Way galaxy—essentially an invitation to find us.

 A Word of Caution


Renowned physicist Stephen Hawking opposed this type of contact. He warned that if the aliens who find Voyager 1 are more powerful or advanced than humans, they might try to conquer Earth instead of communicating peacefully.





 A Speed Like No Other


Voyager 1 is traveling at an astonishing speed of 62,000 kilometers per hour. That’s so fast, it covers four times the distance between Earth and the Moon in just one day.


To put it another way: if Voyager 1 were circling the Earth, it would complete a full orbit in just 40 minutes!

 The Long Journey Ahead


Voyager 1 is heading toward a group of stars in the opposite direction of Alpha Centauri, our nearest stellar neighbor. However, it will take approximately 76,000 years to get anywhere near them.


For context, Alpha Centauri is about 25 trillion miles (40 trillion kilometers) from Earth. Currently, Voyager 1 is at the outermost edge of our solar system, a region of extreme cold and pitch darkness.





 Self-Healing Technology


Weighing about 722 kilograms, Voyager 1 is equipped with an automated system that resets itself every seven days. This ingenious design helps recover from system glitches automatically—a testament to NASA engineers’ brilliance.
