☆ Earth's core may be coated in a layer of crystals created by water leaking from the surface: study
  + stars: | 2023-12-05 | by ( Marianne Guenot | ) www.businessinsider.com   time to read: +6 min
Water leaking into the Earth may be wrapping the core in crystals, a study has suggested. "For years, it has been believed that material exchange between Earth's core and mantle is small. We still don't know everything about our planet's insidesThe Earth's core is only about 1,800 miles under our feet, but it's more inaccessible than Mars. Dan Shim/ASUTo support their hypothesis, the scientists simulated the high-pressure conditions of the outer core in the lab. He added that his calculations show that he can explain the E-prime layer "reasonably well" with a range of water transportation scenarios.

☆ Mercury is slowly shrinking, and it's giving the planet wrinkles

AdvertisementAdvertisementMercury, the smallest planet in the solar system, is getting even — and getting more wrinkles as it does, a new study suggests. Mercury is wrinkling like an old appleLike any other planet, Mercury is losing heat. The study, published in Nature Geosciences on Monday, identified 48 definite and 244 likely grabens on pictures snapped by NASA's MESSENGER probe in 2015. AdvertisementAdvertisementMercury is likely constantly shaking with quakesThe study also suggests Mercury is constantly shaking with quakes, Rothery said. ESA/BepiColombo/MTM, CC BY-SA 3.0 IGOThe next step for Mercury, Rothery said, will be the arrival of a space probe called BepiColumbo.

☆ NASA's InSight lander captured the 'bloop' sound of a meteor falling to Mars

NASA shared the sound of a meteor falling to Mars, with photos of the impact craters, on Monday. The dwindling InSight lander has captured the acoustic and seismic noise of four meteor impacts. NASA/JPL-Caltech/University of ArizonaThe details of the four Mars meteor strikes were published in a paper in Nature Geosciences on Monday.
