As you'll spot in the trailer, the moon isn't a great place to be, where "new nightmares have emerged from the shadows of our long-forgotten moon". When that happened, the asteroid drilled through layers of the moon's crust while losing mass of its own.
Researchers say it could be a huge lump of metal from the asteroid that formed the South Pole-Aitken basin.More news: Wholesale prices blip up 0.1% in May
Scientists have detected a mysterious mass of material beneath a 1,200-mile crater on the surface of the moon (circled).
The researchers have two theories: the first is that the mass is metal from an asteroid that crashed into the Moon, forming the Aitken basin. 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". James called the crater "one of the best natural laboratories for studying catastrophic events" that was influential to the evolution of rocky planets and moons.
Whatever formed the basin almost 4 billion years ago remains a mystery, but the blow was so strong that it likely punched all the way through the moon's crust and tossed part of the lunar mantle - a deeper geologic layer - onto the surface.
The basin itself is thought to have been created about 4 billion years ago, making South Pole-Aitken the largest preserved crater in the solar system.More news: Muncy's blast leads Dodgers past Bumgarner and Giants 1-0
To measure subtle changes in the strength of gravity around the Moon, researchers analyzed data from spacecrafts used for the National Aeronautics and Space Administration (NASA) Gravity Recovery and Interior Laboratory (GRAIL) mission.
Another possibility is the mass might be a concentration of dense oxides associated with the last stage of lunar magma ocean solidification. Scientists at Baylor University published a study detailing their findings of this "anomaly" beneath the moon's largest crater, at its South Pole. More importantly, a sample of that metal could reveal how the impact really occurred, and what the solar system looked like 4 billion years ago.
Additional research and missions will be needed to confirm the presence of asteroid deposits beneath the South Pole-Aitken basin.
If the mass is a metallic asteroid core, it didn't get stuck inside the moon intact; instead, computer simulations suggest it could have spread out as it struck.More news: World Health Organisation confirms Ebola case in Uganda
