Rocky Planets May Have Formed Just 100 Million Years After the Big Bang

The universe may have been building rocky planets almost from the start

Simulations suggest rocky planet building blocks could have formed just 100 million years after the Big Bang.

Rocky planets may have formed just 100 million years after the Big Bang

Rocky planets may have been able to start forming just 100 million years after the Big Bang, thanks to enormous early supernovae that scattered planet-building elements across space. Simulations found enough solid material and water around a young star to suggest that Earth-like worlds could have appeared far earlier than previously believed.
