Collage of all cometary nuclei imaged by spacecrafts and planetary radars, all resampled to a resolution 25 meters per pixel.
It contains all imaged comets up to now.
If comet has been imaged more than once, name of the source is underlined in the caption.
Credits are in the collage.

🚨🚨New paper alert!! 🚨🚨🧪🔭
Today we published exciting new results from the Rosetta mission! These results have big implications for where the comet formed and for whether comets could have supplied water to Earth. #PlanetaryScience #Rosetta 🧵1/n

A nearly terrestrial D/H for comet 67P/Churyumov-Gerasimenko
Analysis of Rosetta measurements suggests that Jupiter family comets could have delivered much of Earth’s water.
