Scientists find new details on how exactly the Moon was formed New research suggests that we might have missed something very important in our understanding of how the Moon formed. The Independent UK · Sep 2
An extra solar system planet once orbited next to Earth — and it may be the reason we have a moon Earth may have a moon today because a nearby neighbor once crashed into us, a new analysis of Apollo samples and terrestrial rocks reveals. LiveScience · Dec 1, 2025
Long lost Moon-forming planet formed in the inner Solar System, new analysis shows Moon’s precursor planet, Theia, disappeared billions ago, leaving scientists no direct chemical evidence to support the hypothesis. Now a team of astromers in France, Germany and the United States have analysed ancient lunar and terrestrial rocks to trace where Theia came from. Euronews · Nov 23, 2025
Earth and Theia smashed to birth the moon, but did they first start out as close neighbors? "The most convincing scenario is that most of the building blocks of Earth and Theia originated in the inner solar system. Earth and Theia are likely to have been neighbors." Space · Nov 20, 2025
Scientists discover first direct evidence that slivers of 'proto-Earth' may survive today In a first, researchers have discovered fragments of Earth's precursor that contain distinctive chemical fingerprints in ancient rocks from Greenland, Canada and Hawaii. LiveScience · Oct 21, 2025
Cataclysmic crash with neighboring planet may be the reason there's life on Earth today, new studies hint Early Earth may not have had the right ingredients for life — until a nearby Mars-size planet crashed into it, two new studies hint. LiveScience · Aug 29, 2025
Earth, Mars, Venus — and a long-lost planet — may have once 'waltzed' in perfect harmony around the sun New simulations suggest that up to four of the solar system's rocky planets, including Earth and a long-lost world, once orbited in mathematical harmony around the infant sun.

How did Earth get such a strange moon? Exploring the giant impact theory The moon is unlike anything else in the solar system. So how did our planet end up with such a special moon? Space · Mar 17, 2025
OPINION - Miserable June: I don't believe it but this bleak weather has me reaching for my gilet Approximately 4.5 billion years ago, astrogeologists (that is, people who study planetary geology, not the grifters who ask for your star sign and suggest that while you might feel overwhelmed, now is a good time to address the big picture stuff in your life) hypothesise that a young Earth collided… Evening Standard · Jun 14, 2024
Is some of the body that collided with Earth to form the Moon still recognisable inside our planet? Scientists have dated the birth of the Solar System to about 4.57 billion years ago. About 60 million years later a “giant impact” collision between the infant Earth and a Mars-sized body called Theia created the Moon. The Conversation · Nov 10, 2023
Relics of huge primordial collision reside in Earth's deep interior Seismologists have recognised since the 1970s that two mysterious continent-sized blobs reside in the deepest part of Earth’s mantle, one under Africa and the other under the South Pacific region The Hindu · Nov 3, 2023
Planet’s Remains Buried In Earth’s Interior, Shaping Its Geography, Study Shows Remnants of ancient planet that formed Moon found buried deep inside Earth, reveals new study. Zenger · Nov 1, 2023
A chunk of the 'protoplanet' that made the moon may be stuck near Earth's core The newborn Earth was struck by a Mars-size rock that helped create the moon, and the impact may have left behind continent-size remnants of the rock near Earth's core, a new study finds. Space · Nov 1, 2023
Blobs near Earth’s core are remnants of collision with another planet, study says New research proposes that impact melted most of both worlds and led to the formation of the moon The Guardian - UK · Nov 1, 2023
