The formation of exoplanets

...managed to form, they tend to interact with each other and with the remaining gas and planetesimals in the disc. Therefore, planets often end up in a different mass and orbital configuration than the one they had at formation. There are several ways this can happen. Interaction with remaining gas in the disc The angular momentum exchange between a planet and the remaining...

...managed to do (and failed to do) before. While other species may not have the same degree of neocortical development and executive function as humans, are they able to use tools to solve problems to some extent? There is evidence that the nearest evolutionary neighbours of humans, the other great apes (gorillas, chimpanzees, bonobos and orangutans), are able to solve...
