Launched in 1977, Voyager 1 is humanity’s farthest emissary, over 15 billion miles (24.8 billion km) from Earth, racing at 38,000 mph (17 km/s). It still carries the Golden Record, a time capsule of Earth’s culture, into the uncharted depths of the cosmos.

A diagram of the Milky Way galaxy showing its spiral structure and major features, with a specific red line indicating the distance Voyager 1 is projected to travel in one million years. The title text at the top left reads: "The red line shows how far Voyager 1 will travel in 1 million years." The main graphic is a top-down view of the Milky Way. Concentric circles are marked with distances from the center in light-years (ly). The galactic center is marked. Galactic Longitude is indicated around the circumference, starting at the top, increasing counter-clockwise. Several major spiral arms are labeled, and other features shown. The red line, originating near the Sun's location, represents Voyager 1's one-million-year travel distance. It extends only a very short, almost imperceptible distance, visually emphasizing the immensity of the Milky Way compared to the probe's travel over that timeframe.

To grasp the vastness of space, Voyager 1 will pass near Gliese 445 in about 40,000 years. Yet even then, it will hardly have traveled across the galaxy. One full orbit of the Milky Way would require over 400 million years—an unimaginable timescale.

Crossing into interstellar space in 2012, Voyager 1 marked a milestone in exploration. Yet on a galactic scale, its motion is almost imperceptible. Even after drifting for a million years, it would remain within the Orion Spur, close to its origins.

Coronal Loops on the Sun

Solar loops, shaped by the Sun's magnetic field, can envelop #Earth and last days. These prominences, often near sunspots, were captured in hydrogen light by a personal #telescope in Italy. Some may break and influence Earth's space weather.
