A team of researchers at the Max Planck Institute for Chemistry, working with a colleague from Université Paris-Saclay, has found evidence that suggests supernovae and their progenitors may have contributed more dust to ...
Before the Earth and other planets formed, the young sun was still surrounded by cosmic gas and dust. Over the millennia, rock fragments of various sizes formed from the dust. Many of these became building blocks for the ...
