Scientists Discover Previously Unidentified Mass Beneath Surface of the Moon (cbsnews.com) 139

pgmrdlm shares a report from CBS News: A previously unknown deposit of an unidentified physical substance larger than the size of Hawaii has been discovered beneath the surface of the moon. Scientists at Baylor University published a study detailing their findings of this "anomaly" beneath the moon's largest crater, at its South Pole. They believe the mass may contain metal carried over from an earlier asteroid crash. According to the study -- "Deep Structure of the Lunar South Pole-Aitken Basin" -- which was published in the journal Geophysical Research Letters in April, the large mass of material was discovered beneath the South Pole-Aitken crater, an oval-shaped crater that is 2,000 kilometers (about 1,243 miles) wide and roughly 4 billion years old. According to Baylor University, the unidentified mass was discovered "hundreds of miles" beneath the basin and is "weighing the basin floor downward by more than half a mile." The scientists discovered the mass by analyzing data taken from a spacecraft used during NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, which was a lunar gravity mapping exploration to study the moon's interior and thermal history.

According to the published study, "Plausible sources for this anomaly include metal from the core of a differentiated impactor or oxides from the last stage of magma ocean crystallization," which hypothesizes the moon's surface was once a molten liquid ocean of magma. They also believe the mass could be suspended iron-nickel core from an asteroid that previously impacted the moon's surface.

              Actually, as kama`aina, we use the `okina in the name of the island, the state, and the whole island chain. Since the US keyboard doesn't have the `okina key (and the English alphabet doesn't include the `okina) it is often omitted when writing in English.

              Partially correct... when most normal people in general talk about the island of Hawaii they usually say, 'The Island of Hawaii'. or 'Hawaii, the island'. Any other island, they will just use the name, like Oahi, or Maui.

        • Hawaii can refer to just the island of Hawaii (the Big Island), the state of Hawaii (8 main islands plus a few uninhabited ones), or the entire archipelago (over 1000 islands). I would also mention Hawaii County, but I believe that is the same thing as the island of Hawaii.

          • I like to read Hawaii News Now and journalists definitely throw in a "Hawaii County" as an alternate way of specifying the big island. But most of the time, Hawaii means the island of Hawaii, and the State is referred to as "the State." Usually when talking about the State they're actually talking about a department of the State government, and they'll say the name of the department on the first use, and then "the State" on subsequent mentions.

      • It's been demonstrated via the coastline paradox (https://en.wikipedia.org/wiki/Coastline_paradox) that Hawaii has an infinitely long perimeter so I think you can say it's 3D size is, "Pretty big, possibly larger".

          Where I live, ~110 years ago there was a bunch of bickering over the waterhole, and people died. Of typhoid fever. The engineers and the owners of the company that controlled the water hole were given a second chance: Sell the waterhole to the local People to be run as part of the government, and you'll be allowed to leave town. They agreed enthusiastically. It was decided to make its own government entity, run by an elected board.

        The TMA-1 monolith transmitted a signal toward Jupiter when it was hit by the sun. It's mentioned somewhere in the film or the book that the monolith hasn't seen the sun yet. This signal is why the Discovery One is heading to Jupiter. Haywood Floyd had instructed HAL to NOT tell Poole and Bowman about the signal and the true purpose of the mission. These instructions are what caused HAL to have his psychotic break and try to kill all the astronauts.

    If it's the largest crater and this was detected based on gravity resulting from a difference in density, what are the odds it's just simply normal moon material compacted denser because of the impact? I assume they ruled that out after comparing the displaced volume of the crater?
    • Normal lunar material would not compress to the density indicated by the anomaly.
      • I suppose it would if you could compress the electrons so that the protons would absorb them. There seem to be some of those wandering around the universe, and I do vaguely recall a science fiction story that featured very small dense masses of that sort scattered around the edges of the solar system. The plot device used such a mass at one end of a very long space ship to create a local gravitational pull sufficient to counteract the effects of high acceleration, allowing the space ship to accelerate to

    • When they talk about something hundreds of miles below the crater weighing the crater floor "down" by half a mile. That's actually, up, not down; the thing making the crater floor heavier is below it, not above it. Weighing up.

      That means it is a lot denser than the stuff above it. Rock doesn't condense in that way, it would be pulverized and also heated by the impact, and it would solidify near the normal density for the materials.

      This is like when the news talks about scientists finding the spot on Earth w

    A justification to go back to the Moon and establish a sustainable human presence (rather than going straight to Mars). The Moon has to be a lot easier destination than an asteroid to mine for materials. But if man still can't drill down for miles to reach the mass, there's no point in spending hundreds of billions to put a semi-permanent US presence there.
