The 3.8-billion-year-old lava that flowed in those basins were thus the last of Mercury’s surface lava. And indeed, the youngest lava plains are all found in the biggest impact basins.

Yet, whereas 31% of the surface of the near side is covered in maria, lava plains are found only on 1% of the farside. Planetary geologists are not sure why this is the case.

The moon may have been more volcanically active than we realized. Lunar samples that China’s Chang’e 5 spacecraft brought to Earth are revealing new clues about volcanoes and lava plains on ...

In the new study, Sood and his colleagues studied GRAIL data to search for small differences that could indicate the presence of lava tubes on the lava plains, or mare, of the moon. Get the Space ...

The lava flows seen in this image come from Arsia Mons, the southernmost volcano in the Tharsis complex, which lies around 620 miles (1,000 kilometers) to the northwest of the region featured here.

That means that lava tubes smaller than about 0.5 miles wide could easily escape detection. Large channels, known as rills, fed the large lava fields on the lunar surface.
