An astronaut on board the Worldwide House Station (ISS) has snapped a surprising picture of an historic lava circulation stretching throughout the desert in New Mexico. From above, the frozen river of volcanic rock appears to be like like a darkish scar carved into the encompassing desert.Â
The basaltic lava circulation, generally known as the Carrizozo MalpaÃs, covers round 130 sq. miles (337 sq. kilometers) and is round 50 miles (80 kilometers) lengthy. It’s positioned close to Carrizozo, a metropolis within the Chihuahuan Desert in New Mexico, and is among the largest lava flows to have fashioned on Earth up to now 10,000 years, based on the U.S. Geological Survey (USGS) (opens in new tab).Â
The eruption that birthed the Carrizozo MalpaÃs started round 5,000 years in the past and lasted for between 20 to 30 years. Throughout that point, magma slowly trickled out of the bottom from a subsurface defend volcano, which has since grow to be dormant. Insulated lava tubes beneath the floor unfold the molten rock out over an unusually massive space, based on USGS.

The brand new picture is a mosaic of 4 pictures taken on June 30 by an unidentified astronaut from the Expedition 67 crew on board the International Space Station. The stitched-together shot, which is among the most detailed aerial photos of the lava circulation ever taken, was launched on-line Sept. 26 by the NASA Earth Observatory (opens in new tab).Â
A majority of the lava within the picture emerged from a small, 88-foot-tall (27 meters) vent, which locals have dubbed “little black peak,” positioned on the north finish of the lava subject (the left-hand facet of the picture). The vent sits in the course of a zone of crustal weak point, generally known as the Capitan lineament, the place magma simply rises via Earth’s crust and erupts on the floor, based on USGS.Â
The uneven, textured look of the frozen lava is the results of mild scattering off fissures, collapses and depressions within the volcanic rock, based on Earth Observatory. A predominant street and railway additionally bisect the northern finish of the lava subject.Â
The traditional lava subject could appear lifeless from above, however various desert plant species, corresponding to prickly pear cactuses (Opuntia), perennial flowers, and juniper bushes, can develop within the frozen magma, based on Earth Observatory. Â
