Detected many strange lava columns on Mars

An American student has discovered lava flows that look like ropes near the equator of Mars. This is the first time to detect such geological characteristics in an extraterrestrial place.

This tortuous volcanic lava flow can be found on Hawaii's Big Island and the Pacific bottom. But this is the first time that Mars has detected similar characteristics.

This is the discovery of Andrew Ryan, a graduate of Arizona State University. Ryan reported this discovery on Science magazine on April 27.

But the most surprising thing is the column of lava on Mars 30.5 meters wide - wider than any lava column on earth. This is evidence that reinforces the argument that Mars volcanoes are both active - geologically for about 20 million years.

Ryan analyzed about 100 high-resolution photos from the Mars Mars Reconnaissance Orbiter since 2006. Ryan discovered 269 columns of lava from 5 to 30.5m wide.

Lava flows spiral on Mars.

Planetary research scientist David Paige at the University of California says the finding provides compelling evidence of volcanic activity on Mars.

There is no clear indication that the area is still active today. Ryan thinks that lava rolls may be available elsewhere on the red planet.

Scientists believe that lava flows flow through the valleys on Mars to a very wide basin. Spiral lava columns are formed when lava flows are cooled.

For more than a decade, scientists have always argued whether maze of Mars's equatorial valleys is affected by volcanic eruptions or volcanoes.
