SpaceTime Series 27 Episode 154
*The Moon's Age: A New Perspective
New research suggests the Moon may be much older than previously believed. Evidence indicates the Moon's crust underwent extensive remelting around 4.35 billion years ago, obscuring its true age. This study proposes the Moon could be as old as 4.53 billion years, challenging past estimates and offering a new understanding of its formation.
*Perseverance Rover's New Horizons
NASA's Perseverance rover has reached the top of Jezero Crater's rim, marking a significant milestone in its mission. With the climb complete, the rover is set to explore new geological terrains, potentially uncovering some of the oldest rocks in the solar system. This new phase promises to deepen our understanding of Mars' ancient history.
*Unveiling South Australia's Pink Sands Mystery
The discovery of deep pink sands on South Australian beaches has provided insights into the tectonic history of the region. These findings, published in Communications Earth and Environment, suggest the existence of an ancient Antarctic mountain range, offering clues about the geological past of the supercontinent Gondwana.
