Scientists Say the Moon Is Way Younger than We Thought – Futurism

Goodnight, Moon.

Just A Kid
According to a sophisticated new model, the Moon is far younger than scientists previously thought to the tune of some 85 million years.
Its not such a drastic shift when you consider how long the Moons been around. The research, published Friday in the journal Science Advances, adjusts the age of the Moon from 4.51 billion years old to 4.425 billion, with 25-million-year-long error bars on either side. But it does clarify some of the mysteries surrounding how it formed in the first place.
Magma Ocean
The prevailing theory is that a Mars-sized rock crashed into the Earth and the debris eventually consolidated to form the Moon. The still-forming Earth may have been covered by an ocean of magma and this new research posits that the Moon had a magma ocean over 1,000 kilometers deep as well.
The main disagreement, however, is over how long it took that ocean to cool: Existing models said the Moon solidified after 35 million years.
The results from the model show that the moons magma ocean was long-lived and took almost 200 million years to completely solidify into mantle rock, lead author Maxime Maurice, a planetary geophysicist at the German Aerospace Center, said in a press release.
Minor Adjustment
By modeling how the composition of the Moon rocks formed by that ocean changed over time, the team was able to arrive at its new age for the Moon.
The new timeline ties neatly to the Earths history as well, meaning the Moon formed at about the same time as the Earths core.

The dwarf planet Ceres — long believed to be a barren space rock — is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed Monday.
Ceres is the largest object in the asteroid belt between Mars and Jupiter and has its own gravity, enabling the NASA Dawn spacecraft to capture high-resolution images of its surface. 
Now a team of scientists from the United States and Europe have analysed images relayed from the orbiter, captured arou…

The English town of Lyme Regis is part of the Jurassic Coast World Heritage Site. It was here in the 1830s that William Buckland, better known for the discovery of the first dinosaur, Megalosaurus, collected fossils with another pioneering palaeontologist, Mary Anning.
One of their discoveries was the remains of fossilised crinoids, sometimes known as “sea lilies”. Close relatives of sea urchins and starfish, these flower-like animals consist of a series of plates connected together in branches…

WASHINGTON (Reuters) – Ceres, the largest object in the asteroid belt between Mars and Jupiter, is an “ocean world” with a big reservoir of salty water under its frigid surface, scientists said in findings that raise interest in this dwarf planet as a possible outpost for life.
Research published on Monday based on data obtained by NASA’s Dawn spacecraft, which flew as close as 22 miles (35 km) from the surface in 2018, provides a new understanding of Ceres, including evidence indicating it re…
