A new way has been discovered to make oxygen without plants.
Researchers from the University of California in Davis have found a way of converting carbon dioxide into oxygen.
The new research could help experts understand the Earth’s early atmosphere, and find out how other planets filled with carbon dioxide may form oxygen.
Even though scientists think plants produced most of the oxygen present on Earth, they now believe some oxygen may have existed before plants arose.
This means that the search for alien life may need to be altered.
Experts say the new research may prove that it's possible to make oxygen in space or on other planets without the need of plant life.
