DR Congo ring may be giant 'impact crater'

Deforestation has revealed what could be a giant impact crater in Central Africa, scientists say.



The 36-46km-wide feature, identified in DR Congo, may be one of the largest such structures discovered in the last decade.

Italian researchers considered other origins for the ring, but say these are unlikely.

They presented their findings at the recent Lunar and Planetary Science Conference in Texas, US.
