(Phys.org) —A combined team of researchers from Germany, Switzerland and the U.S. has found evidence of faster than thought core formation of planetesimals in our solar system. In their paper published in the journal Science, ...
The solar system as we know it formed about 4.6 billion years ago as fields of interstellar dust orbiting the sun aggregated into planets and smaller objects. Presolar dust particles no longer exist in the inner solar system, ...
How soon after the Big Bang could water have existed? Not right away, because water molecules contain oxygen and oxygen had to be formed in the first stars. Then that oxygen had to disperse and unite with hydrogen in significant ...
