SHOCKING! Earth's Day Wasn't Always This Long: New...

Geo-News Radio ·

2024/09/08

A new study published in the Proceedings of the National Academy of Sciences reveals that Earth's rotation hasn't always slowed down at a steady pace. By analyzing geological data, scientists have discovered a staircase-like pattern in Earth's rotational history. There were periods of rapid deceleration followed by intervals where the rotation speed remained stable. The researchers believe this pattern is caused by tidal dissipation resonance, the gravitational interaction between

The Lithium Mystery: Challenges in Understanding the...

Geo-News Radio ·

2024/08/18

The "Lithium Problem" is a significant challenge in cosmology, arising from discrepancies between the predicted and observed abundances of lithium isotopes in the universe. According to the standard Big Bang nucleosynthesis theory, the early universe should have produced about three times more lithium-7 than is actually observed in stars and other cosmic bodies. This discrepancy is compounded by the isotope lithium-6, where observations show 1,000 times more than theoretical models

Geo-News Radio ·

2024/08/17

The origin of gold in the universe is closely linked to cosmic events such as gamma-ray bursts and the collision of neutron stars. Gamma-ray bursts, which are intense flashes of gamma radiation, can result from the explosive deaths of massive stars or the merger of neutron stars and black holes. These events are significant because they can lead to the formation of heavy elements through a process known as rapid neutron capture, or r-process nucleosynthesis. During this process, neutron-rich ...

Scientists have discovered evidence of liquid water on Mars, buried deep within the planet's mid-crust, in fractures several miles below the surface. This groundbreaking finding, led by researchers from the University of California, San Diego's Scripps Institution of Oceanography, represents the best evidence yet that Mars still harbors liquid water, in addition to the frozen water at its poles. The study, published in the Proceedings of the National Academy of Sciences, suggests that the

Understanding ColTan Mineralization: A Key to the...

Geo-News Radio ·

2024/08/13

Underground coltan mining begins with deposit development, where shafts and chutes are excavated to access the ore body. Miners then use techniques such as drilling, blasting, and manual extraction to mine the ore. Once extracted, the ore is transported to the surface for processing, where coltan is separated from other materials using gravity separation methods. This ensures that the tantalum and niobium content is concentrated for further metallurgical processing.The metallurgical process i...

2024/08/11

Iceland's recent volcanic eruptions, particularly those near the Reykjanes Peninsula, may mark the start of a prolonged period of volcanic activity. The country’s unique geological setting on the Mid-Atlantic Ridge, where tectonic plates are constantly shifting, contributes to its high level of volcanic activity. The ongoing eruptions, which began in 2021, could be part of a larger cycle that may last for decades. This suggests that Iceland might be entering a new era of volcanic unrest, with...

The Iwo Jima volcano, located on the Japanese island of Iwo Jima, has recently entered a new phase of eruptive activity, drawing significant attention from the scientific community. In mid-July 2024, the volcano began ejecting molten lava that formed unique "lava balloons" - spherical formations created when lava is rapidly cooled by seawater, resulting in a solid outer shell with a still-molten interior. These floating lava balloons have created a striking visual phenomenon in the waters sur...
