During the modern era of space exploration, the planets of our solar system have been viewed with increasing clarity, thanks to the distant voyages of unmanned spacecraft and the development of ever-more powerful telescopes. With this digital stamp art, the U.S. Postal Service® showcases some of the more visually compelling full-disk images of the planets obtained during this era. Eight colorful stamps feature Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Some show the planet’s “true” color—what we might see with our own eyes if traveling through space. Others use colors to represent and visualize certain features of a planet based on imaging data. © 2024 United States Postal Service®. All Rights Reserved. Used with Permission
