Japanese orbiter found a Volcano on the Moon


In the article published in the journal Geophysical Research Letters, a Japanese researcher Junichi Haruyama says that the Japanese orbiter Kaguya lunar surface found at least one crater, which is an extinct volcano.


The diameter of the crater is about 65 meters, it is located in a volcanic region of Marius Hills, on the side of the moon that faces the Earth. Japanese scientists say the crater, leaving the surface of the Moon, is a "pipe" through which previously appeared on the surface of the molten lava. Astronomers immediately attracted to this crater, as it was different from many others.

"Of course, there are lots of possible options for the origin of the holes on the surface of the moon. The most obvious — a meteorite strike, despite the fact that the moon is often bombed meteorites. However, this is an untenable version. Kaguya observed crater nine times at different angles, in different light conditions, including when the sun was shining on the crater is almost perfect. Our calculations showed that the depth of the crater at least 88 meters. The meteorite is not able to create a hole, "- says Haruyama.

Another option that came to mind scientists — the mouth of the volcano. However, near the crater until no traces of eruptions, including lava flows and volcanic dust. At present, the mouth is in an isolated position. The cause of this anomaly, Japanese scientists say is this: because of the very deep crater, volcanic eruptions could just not reach the surface. Another option would be that the lava is hidden from observation layer of lunar soil.

Japanese experts suggest that if there really was a lava then look for traces of monitors within a radius of 370 meters from the crater. In the publication, scientists note that if the lava will still be found, but in the future it will be possible to study, then people will have unique data on the internal structure of the Moon.
