In a study published in the journal Nature Geosciences, in the future, people will enjoy the beautiful scenery, the volcanic eruptions on the Moon as seen from Earth.
Using information collected by seismometers installed in the Apollo moon missions when deployed, it is known that about 30 percent of the core layer that surrounds the moon is made of liquid metal.
According to Renee Weber, researchers from NASA's Marshall Space Flight Center, who chaired the mapping and modeling study of the Moon, molten lava was at a depth of 1200 to 1350 kilometers below the surface of the Moon.
Then, why is there no active volcanoes in there?
Quoted from Gizmodo, February 21, 2012, the Moon's surface like a dead planet. The last volcanic eruption occurred in the Moon occurred several billion years ago.
To find out whether there will be volcanic eruptions on the moon, a group of researchers headed by Parker and Mirjam van Kan Wim van Westernen from VU University, Amsterdam trying to find the answer.
Since humans can not access the existing lava on the moon, the researchers used a sample of rock weighing 350 pounds that was taken by the Apollo of the Moon. They then put the stone in the stomach conditions similar to the Moon. Ie with more than 45,000 bar pressure and temperatures around 1,500 degrees Celsius.
After creating an artificial lava, they then analyze and create a computer simulation. Apparently, it is known that the Moon magma rich in titanium.
That is, the molten lava was too heavy to be able to flow to the surface of the Moon. In fact, so the lava can be erupted on the lunar surface, he needed more light.
"Once the magma is formed, they accumulate in the lower layers of the Moon. Something like a volcano but in reverse. Currently, the Moon is in the cooling phase, as well as the inside, "said Westrenen. "It answers the question why there are no volcanoes on the moon," he said.
But, what about the future?
In the future, cooler lava it will change its composition. Chances are, he will be less dense than the substances around them. "Magma is lighter it can easily move to the surface and form volcanoes on the moon," said Westrenen. "That would be a very beautiful," he said.
Unfortunately, none of us who live today can see the phenomenon of volcanic eruptions on the Moon. Because the process would take millions of years.
