… From Martian Moon Phobos.

"NASA's InSight mission provides data from the surface of Mars. Its seismometer, equipped with electronics built at ETH Zurich, not only records marsquakes, but unexpectedly reacts to solar eclipses as well. When the Martian moon, Phobos moves directly in front of the sun, the instrument tips slightly to one side. This miniscule effect could aid researchers in determining the planet's interior.

An observer standing on Mars would see the planet's moon Phobos cross the sky from west to east every five hours. Its orbit passes between the sun and any given point on Mars about once each Earth year. Each time it does so, it causes from one to seven solar eclipses within the space of three days. One place where this happens is the site of NASA's InSight lander, stationed in the Elysium Planitia region since November 2018. In other words, the phenomenon occurs much more frequently than on Earth, when our moon crosses in front of the sun. "However, the eclipses on Mars are shorter – they last just 30 seconds and are never total eclipses," explains Simon Stähler, a seismologist at ETH Zurich's Institute of Geophysics. Photos taken by NASA's two Mars rovers, Opportunity and Curiosity, also show a sharp-​edged lump against the backdrop of the sun…"

How is this a surprise? Every earthling knows that we have the best solar eclipses. We're #1, we're #1!

You want the simple


or the complicated explanation?
