Good morning, Rallypoint, and welcome to the February 1, 2026 edition of Astronomy Picture of the Day (APOD).
First featured here in 1999, this image of Crater Galle (aka the Happy Face Crater) was captured by NASA's Martian Global Surveyor (MGS). Viking 1 took this first photographs in 1976. And it does resemble the smiling/winking emoji used online in lighter moments.
This impact formation is named after Johann Gottfried Galle, a German astronomer who first observed the planet Neptune on September 23, 1846. How big is Crater Galle? Over 140 miles in diameter.

Take a moment to examine the photograph above. What do you see? Take your time, be patient and focus on what's leaning against the big rock just left of center. For scale, the boulder above is roughly one meter in diameter. Take a moment to examine the photograph above. What do you see? Take you...

Yeah like that. Lava flows are crazy and hard to imagine. Yellowstone has a pretty large on.
