The National Aeronautics and Space Administration (NASA) announced that it would organize a worldwide celebration to mark Voyager 1, the most distant human-made object, reaching a distance of one light-day from Earth.

Launched in 1977, Voyager 1 will reach a historic milestone on November 18, traveling more than 16 billion miles (25.9 billion kilometers) from Earth. Light sent from Earth will take approximately 24 hours to reach the spacecraft.

To celebrate this achievement, NASA will launch a worldwide event on November 17 in which smartphones and tablets will flash the letters "VGR," Voyager's call sign, using Morse code. Participants will be able to share photographs and videos of their light signals on social media.

Meanwhile, NASA's Jet Propulsion Laboratory will hold an event on November 19 to discuss the current status of the Voyager 1 and Voyager 2 missions, the scientific data collected by the spacecraft from interstellar space, and the technical challenges facing the missions.
