Large tunnel spotted on moon
Scientists have spotted a deep hole in the lunar surface that could provide shelter for future astronauts against the harsh radiation and surface temperatures on the moon.
The tunnel goes at least 260 feet down and is believed to open into an underground tunnel more than 1,200 feet wide.
The discovery is powerful evidence for long, winding tunnels carved by lava beneath the lunar surface, New Scientist magazine said in a recent report.
Such tunnels, whose existence has long been hypothesised, could provide shelter for future astronauts or colonists against the harsh radiation and surface temperatures on the moon, scientists said.
Previous signs of such tunnels only existed as surface features called rilles, which hinted at hollow lava tubes below. Researchers only found the hole by poring through images taken by Japan’s deceased Kaguya lunar probe.
Scientists said that rubble or solidified lava may have blocked off much of the underground tube. But the Kaguya team continues to search for more openings, and NASA’s Lunar Reconnaissance Orbiter could also begin snapping new shots of the area that are 10 times sharper. — PTI
