CometsComet compositionCometary evolutionThe ISSI workshop on "Origin and evolution of comet nuclei" had the goal to put together recent scientific findings concerning the "life" of a comet from the formation of the material in a dark molecular cloud to the accretion in the early solar system,...
This disintegration was observed by many astronomers and provided valuable information about the composition of comets. The Hale-Bopp CometDiscovered in 1995 by Alan Hale and Thomas Bopp, the Hale-Bopp Comet is one of the most famous comets in recent history. It was visible to the naked eye...

Overall, the green color of comets is a result of the complex interplay between the solar radiation, the composition of the coma and tail, and the physical properties of the gas and dust in the coma. What if I miss watching C/2022 E3 (ZTF)?
“This native woodland restoration was approaching the structure (but not the species composition) of long-established woodlands within six decades,” the researchers explained in the study. Part of this reforestation was done by the...
