Скачать или смотреть Voyager 1: 1 Light-Day From Earth (16.1 Billion Miles Explained)

Voyager 1 is about to hit a mind‑bending milestone: within a year, it will be 1 light‑day away from Earth — 16.1 billion miles into interstellar space.
In this video, you’ll learn:
What a light-day actually is and why it equals about 16.1 billion miles.
How long it takes light and radio signals to travel that distance.
How Voyager 1, launched in 1977, has spent decades flying past Jupiter, Saturn, and into interstellar space.
Why reaching a light-day from Earth is such an important symbolic milestone for humanity.
How far a light-year is (nearly 6 trillion miles) and how that compares to a light-day and an astronomical unit (AU).
How small our solar system is in comparison, with about 3.7 billion miles from the Sun to Pluto.
Where Voyager 1 is right now and how long it takes to send a signal there and get a response back.
How engineers fixed a critical onboard computer glitch that started in November 2023 and brought its data stream back.
Why Voyager 1 is gradually losing power as its radioisotope thermoelectric generators (RTGs) decay, and what that means for its mission past 2030.
What will happen when Voyager 1 finally goes silent but keeps traveling for billions of years into deep space.
The story of the Golden Record on board: what’s on it, how aliens could play it, and why Carl Sagan helped design this message from Earth.
Perfect for space fans, sci‑fi lovers, and anyone curious about just how far humanity has reached into the cosmos.
