‘Lunar bridge’ discovered on far side of MoonPublished On: Thu, Sep 9th, 2010 | Science | By BioNews
NASA’s Lunar Reconnaissance Orbiter (LRO) has discovered a natural lunar bridge on the far side of the Moon.
Mark Robinson, Principal Investigator of the LRO Camera team, said that the bridge was seven metres wide and 20m long and spanned a canyon between two and four stories deep, reports News.com.au.
“Natural bridges on the Earth are typically the result of wind and water erosion – not a likely scenario on the Moon,” he said.
NASA believes that the bridge formation may be a result of the collapse of a lava tube.
“Scientists believe that the astonishing formation is the result of ancient lava flows which left hollow tunnels, which in this case have fallen away and created the bridge like structure,” NASA said.
