New Study Reveals The Moon Is Older Than Previously Believed

The Moon may be significantly older than once thought, with its age now estimated to be between 4.43 and 4.53 billion years—up to 180 million years older than earlier calculations, according to a new study published in Nature and cited by DPA.

Key Insights From The Study

  • Reevaluation of Rock Samples: The study, conducted by researchers from the US, France, and Germany, suggests that previous interpretations of Moon rock samples were flawed. The samples, primarily collected during the Apollo missions, reflect the cooling of magma on the lunar surface, not the Moon’s initial formation.
  • Early Formation Process: Shortly after Earth’s formation about 4.5 billion years ago, a celestial collision with a planet-sized object named Theia ejected molten rock and debris into space. This material eventually coalesced to form the Moon. The new analysis suggests that tidal forces exerted by Earth on the Moon’s elliptical orbit caused the Moon’s interior to superheat, pushing magma to the surface.
  • Discovery of Ancient Crystals: The presence of zircon crystals in lunar rock samples further supports the claim that the Moon’s age is older than previously believed. These crystals predate the cooling of the Moon’s surface, offering evidence that the natural satellite’s formation occurred earlier than past estimates.

Revised Age Of The Moon

The study’s authors, Francis Nimmo, Torsten Klein, and Alessandro Morbidelli, argue that the Moon’s age should be reconsidered based on these findings. Their research aligns with dynamic models of planetary formation within the Solar System, supporting the idea that the Moon’s development occurred earlier and more rapidly than previously assumed.

Historical Context

Prior to this study, the Moon’s age was estimated at around 4.35 billion years, a figure derived from the cooling ages of surface rocks collected during the Apollo missions. However, the discovery of older zircon crystals in lunar rocks challenged this timeline, prompting further analysis.

Significance of the Findings

These new insights offer a deeper understanding of the early stages of planetary formation and the complex processes that shaped the Earth-Moon system. By pushing back the timeline of the Moon’s formation, scientists can better model the development of celestial bodies in the early Solar System.

This revelation not only redefines the Moon’s place in the timeline of the cosmos but also underscores the importance of continued analysis of lunar samples as a means to unlock the secrets of our planetary origins.

TikTok Returns To US App Stores 

TikTok is once again available for download in the Apple and Google app stores in the US, following a delay in the enforcement of its ban by former President Donald Trump. The ban’s postponement until April 5 gives the administration additional time to evaluate the situation.

Key Developments

The decision to restore TikTok access came after Google and Apple received reassurances from the Trump administration that they would not face legal consequences for reinstating the Chinese-owned app. According to Bloomberg, US Attorney General Pam Bondi sent a letter outlining these guarantees.

In an executive order signed on January 20, Trump instructed the attorney general not to take enforcement action for 75 days, providing time for his administration to determine how to proceed.

Uncertain Future For TikTok In The US

While TikTok is back on the US app stores, its long-term survival remains uncertain. If no deal is reached by early April to address national security concerns, the app may face another shutdown. ByteDance, the parent company, has insisted that TikTok is not for sale.

Legislation And Pressure On ByteDance

The Protecting Americans from Foreign Enemy-Controlled Apps Act, which passed with bipartisan support in Congress, mandates a nationwide ban on TikTok unless ByteDance sells its US operations. This law was signed by President Joe Biden in April of last year.

In late January, the app was briefly removed from US stores following the ban’s activation, impacting over 170 million American users. However, TikTok was restored soon after, following Trump’s intervention in his first hours as president. During that time, he signed an executive order allowing 75 days for a deal that would safeguard national security. Trump also suggested that the US could take a 50% stake in TikTok, a move he believed would keep the app “in good hands.”
