Our Solar System is just out there, beyond Earth's soft blue sky, doing its job, every minute of every day, every year.
We're grateful for a tiny spacecraft almost 100 million kilometers (62 million miles) away.
The European Space Agency's Mars Express mission recently saw an eclipse between Jupiter's four Galilean moons and the smaller Martian moon Deimos.
Mars was 745 million kilometers from its big neighbor, but Deimos and the Jovian system briefly appeared like one happy family.
These astronomical bodies aligned on February 14, 2022, and 80 photos were stitched together to make a movie.
The footage shows 15-kilometer-long Deimos slowly migrating from left to right. It occults Europa, Ganymede, Jupiter's disc, Io, and Callisto, Jupiter's second-largest moon.
Deimos and Phobos may have been part of a bigger body that broke apart or a passing asteroid trapped by Mars' gravity.
Phobos is slowly approaching Mars, and experts believe that within 100 million years, its gravity will shatter the moon, creating a temporary Phobos ring around the planet.
Scientists believe it will eventually escape Mars' gravitational pull and explore the Solar System.
