SETI Institute<a href="https://mastodon.social/tags/PPOD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PPOD</a>: On Wednesday, March 19, ESA released a portion of the Euclid mission’s data to the public. This image shows about 1.5% of Euclid’s Deep Field South, one of three regions of the sky that the telescope will observe for more than 40 weeks, spotting faint and distant galaxies. One galaxy cluster near the center is almost 6 billion light-years away from Earth. Credit: ESA/Euclid/Euclid Consortium/NASA; image processing by J.-C. Cuillandre, E. Bertin, G.

The peculiar anatomy is most likely caused by the gravitational pull of the other two members of the trio.

ESA released these images from its Mars Express orbiter a few months ago. They capture Mars' potato-shaped moons, Phobos and Deimos, as Phobos crosses in front of (or occults) Deimos.

These rocks likely formed as groundwater trickled through rock in the ancient past, depositing mineral cements over time. When the rock was exposed to the atmosphere many years later, wind eroded the softer material around the cemented portions.
