A collaboration of scientists from California and Hawaii have explained how interstellar dust left over from asteroids and comets could deliver water and organic matter to Earth and other planets. They say we are constantly “rained down” upon by these interplanetary dust particles, or IDPs. The IDPs are bombarded by solar wind, especially hydrogen ions, which disturb the order of atoms in the silicate mineral crystal. This leaves behind oxygen, which is more readily available to react with hydrogen to create water molecules. They said the same mechanism would work for exoplanets.
