Is the man on the moon a plumbing system? #Procellarum #ManOnMoon

Science is great. We think we have a problem solved, all the loose ends tied up, and then up pops a new discovery. Some see this as evidence of science’s fragility. Of course those people don’t understand the scientific method. In science, nothing is sacred, nothing is sacrosanct, everything is open to new data.

The latest episode to remind us of the power of the scientific method involves the Man on the Moon – the dark region known as Procellarum that is easily visible from Earth. As one of many Lunar Maria, we automatically thought it formed the same way as the other Maria – a late giant impact broke through the surface and cause lava to flow up, which then cooled as the dark material we see. But new data obtained by NASA’s GRAIL mission reveals that the Procellarum region likely arose not from a massive asteroid strike, but from a large plume of magma deep within the moon’s interior.

Scientists have created a map of the Procellarum, and found that its border is not circular, but polygonal, composed of sharp angles. These could not have been created by a massive asteroid. Instead, it is more likely that these were produced by giant tension cracks in the moon’s crust as it cooled around an upwelling plume of hot material from the deep interior. As cracks occurred, they formed a “plumbing system” in the moon’s crust through which magma could meander to the surface.

So it turns out that we were right about the lava flow part, but at least for this Maria, we were probably wrong about how the lava came up.

  1. This article is specially interesting because the Procellarum is visible from earth. It is amazing seeing how nothing is written on stone when it comes to science. The theory that the Procellarum arose from a massive asteroid strike is not longer valid. Data reveiled that it was caused from a large plume of magma deep within the moon’s interior. Who knows if in a couple of years new data will bring a new theory behind the formation of the Procellarum.

  2. Astronomy has always interested me and amazed me with all the new discoveries that have been made. This new idea of the way The Man on the Moon was created makes more sense to me. I thought about a puddle of glue, or dried up pudding or jello. As these dry up, they tend to get cracks in them. I imagine this is what the moon was like. And since cracks formed, the lava surfaced up through the cracks, dried up and created Maria. It is interesting to learn and to think about how the moon really did form.

  3. Since we believe that the moon was apart of the earth but we didn’t know was small secrets within the moon. Its incredible to find new facts and to discover more about our moon.

  4. Its amazing how science unreveals some of the hidden secrets and definately its not scared! If we believe that the procellarum is made by the plume of lava deep under the moon´s interior, does that indicate moon has the same core as earth and there could be sign of gravitational force on the moon.

  5. It is interesting how colliding objects have had such a huge impact on how planets, moons, and small bodies turn out. Environments and characteristics of the objects are affected and even whole new bodies can be formed from the debris. It will be exciting to watch as new discoveries continue to be made.

  6. Another new discovery, this is what I like about science. We never quit learning and discovering about the world we live on and the galaxy around us! What’s next?

  7. I feel that new discoveries is what makes our universe such a great place to discover. It is constantly bringing new findings such as Pluto no longer being a planet it is no surprise that we are now discovering new things like this Procellarum on the moon, which makes you wonder about what we know so far about the moon and if it is possible for it to change.

  8. I wonder what could have caused the sudden upheaval leading to the plumbing system.. How about the other Maria? I love the new ideas and opportunities that have popped up and into view.

  9. Its pretty interesting that the moon is believed to have been covered in boiling magma in its early existence, and then hardened later one. But that the procellarum caused it to be solid and to shrink from what it is now.

  10. The discovery of how the Man on the Moon was possibly made is very interesting. So if it was made by a plume of lava underneath the surface, what does that mean the moon is really made out of? Does it have a hot core like Earth. This is a fascinating new idea.
