Mysteries are like Siberian craters. When one is solved, a new one opens up.
Or, in this case, 7,000 may open up. According to a new study reported in the Siberian Times, researchers have identified over 7,000 methane bubbles just beneath the permafrost surface in the areas of northern Siberia where bubbles like these have exploded or collapsed over the past few years to form huge craters, including the Batagaika Crater, which is living up to its reputation as the Doorway to the Underworld by continuing to expand and swallow up Siberia. We may soon gaze up at the Moon and think, “It looks just like Siberia.”
