The Martian moon Phobos crosses in front of the Sun on March 26, 2019. Curiosity’s used its telephoto-lens camera, called Mastcam, equipped with a solar filter to capture the event which lasted only 35 seconds. It’s sped up here by a factor of 10. NASA/JPL-Caltech/MSSS
NASA’s Curiosity rover whipped out its eclipse glasses over the last few weeks to capture these amazing images of the moons Phobos and Deimos eclipsing the sun. The rover snapped pictures Phobos, the larger of the two planet’s moons at 16 miles (26 km) across, on March 26. Deimos (10 miles / 16 km) had its day in the sun on March 17.
Deimos transits the sun on March 17, 2019. The images have been sped up by a factor of 10. A typical transit last about 2 minutes. NASA/JPL-Caltech/MSSS
Phobos doesn’t completely cover the sun, so this would be considered an annular solar eclipse. Annular eclipses on Earth happen when the moon is farthest from the Earth and only covers the center of the sun, not the edges.
