Explanation: This kilometer high cliff occurs on the surface of a comet. It was discovered on the dark nucleus of Comet Churyumov - Gerasimenko (CG) by Rosetta, a robotic spacecraft launched by ESA, which orbited the comet from 2014 to 2016. The ragged cliff, as featured here, was imaged by Rosetta early in its mission. Although towering about one kilometer high, the low surface gravity of Comet CG would likely make a jump from the cliffs by a human survivable. At the foot of the cliffs is relatively smooth terrain dotted with boulders as large as 20 meters across. Data from Rosetta indicates that the ice in Comet CG has a significantly different deuterium fraction -- and hence likely a different origin -- than the water in Earth's oceans. The probe was named after the Rosetta Stone, a rock slab featuring the same text written in three different languages that helped humanity decipher ancient Egyptian writing.

Looks like a great place to practice my free fallin’

The novel theory that our oceans formed from comets continues to be challenged by the observational evidence. It seems that water was an abundant compound during the formation of the planets and moons.
After the Sun went through its T-Tauri phase and the Earth’s volatile primordial atmosphere was blown away, subsequent outgassing from increased volcanic activity would have injected ~100 bars (atmospheres) of water vapor into Earth’s atmosphere. Once the atmosphere cooled to saturation vapor pressure, the water vapor would have rained out to form our oceans. The oceans provided a crucial component for a habitable planet and the emergence of life.
The oceans continue to stabilize Earth’s climate to ensure that the environment does not become hostile to life. The presence of a large moon and a strong magnetic field are important too. That and the fact that the Sun emits a significant amount of light in the visible region of the electromagnetic spectrum. The oceans are most transparent to light in the visible range of the electromagnetic spectrum, an inherent property of water. We really do live on a Goldilocks planet.
But the pseudoscientists prefer to propagate their precious theory that the oceans came from comets; most likely to push their ad-hoc theory that life came from comets too (panspermia). If a theory does not agree with experiment, the theory is wrong. I don’t care who thought of it, what his name is, or how beautiful the theory is. If it does not agree with experiment, it’s wrong. In that simple statement is the key to science. [1]

It would be cool to actually STAND on that comet and view it close up!
I read your profile page-very VERY well said!🙂
I saw this on an episode of Stargate and Star Trek Enterprise.
