Venus springs ozone layer surprise (BBC)

By Jennifer Carpenter
Science reporter, BBC News

Scientists have discovered that Venus has an ozone layer.

The thin layer, which is hundred of times less dense than the Earth's, was discovered by the European Space Agency's Venus Express craft, researchers report in the journal Icarus.

Until now, ozone layers have only been detected in the atmospheres of Earth and Mars.

The find could help astronomers refine their hunt for life on other planets.

The European spacecraft spied the ozone layer when focusing on stars through Venus' atmosphere.
