Previously unpublished photos of Mars' moon Phobos hint that
the mysterious satellite may actually be a trapped comet — or perhaps just a piece of one, along with its twin moon Deimos.

Mars' moon Phobos may actually be a comet — or at least part of one — that was gravitationally captured by the Red Planet long ago, a new preprint study based on previously unpublished photos suggests.For years, researchers have puzzled over the origins of Phobos and its twin, Deimos. Some have theorized that the moons are former asteroids lured in by
Mars' gravity, because their chemical composition is similar to that of certain rocks in the main asteroid belt between Mars and Jupiter. However, computer models simulating this capture process have not been able to replicate the pair's near-circular paths around Mars.
Another hypothesis suggests that a
giant impact, like that which created our
moon, gouged the duo out of the Red Planet; but Phobos has a different chemical composition from Mars, making this scenario unlikely, too.
Figuring out exactly how Phobos was born is one of the aims of the Japan Aerospace Exploration Agency's
Martian Moons eXploration (MMX) mission, slated to launch in 2026.
Sonia Fornasier, an astronomy professor at the Paris Cité University and lead author of the new study, is an instrument scientist for the MMX mission. While she and other scientists were analyzing images to fine-tune the spacecraft's planned path, Fornasier stumbled upon unpublished photos.
Comment: Chemtrails, and geoengineering, are indeed real, however, whilst these rather nefarious practices have gained significant traction in the public consciousness in just the last year or so, they seem to be distracting from another the significant changes occurring in our atmosphere - which is also evident in a variety of other strange sky phenomena, including Transient Luminous Events, iridescent clouds, low lattitude and multicoloured aurora, to name a few - and which, unlike those man-made problems, cannot be stopped, and foreshadow greater Earth Changes up ahead:
