Comet impacts could jump-start life on early Earth

Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon...

Gas on Saturn’s moon Enceladus could be ‘free lunch’ for alien life

The subsurface ocean of Saturn’s moon Enceladus probably has higher than previously known concentrations of carbon dioxide and hydrogen and a more Earthlike pH...

Scientists decipher the history of supermassive black holes in the early universe

Astrophysicists at Western University have found evidence for the direct formation of black holes that do not need to emerge from a star remnant. The...
