Oort Cloud — NASA Most stars form in dense stellar environments, where frequent close encounters can strongly perturb and reshape the early architecture of planetary systems. The solar system, with

New research uses laboratory experiments to demonstrate that water is naturally created during the planet formation process. By squeezing and heating planetary analog materials between the tips of two diamonds,
