Page 9: Research news on Earth-moon system
The Earth–Moon system as a research area encompasses the coupled dynamical, geophysical, geochemical, and space-environment interactions between Earth and its natural satellite, studied using observational, theoretical, and numerical methods. It includes investigations of orbital and rotational dynamics, tidal dissipation, angular momentum exchange, and long-term evolution of the Earth–Moon distance and obliquity. Research targets internal structure and thermal histories inferred from gravity, seismology, and magnetic data; surface and exospheric processes; impact cratering; and volatile and isotopic compositions. The field also examines Earth–Moon space weather, plasma and magnetospheric interactions, and implications for planetary system formation, comparative planetology, and future exploration architectures.
How did Jupiter's Galilean moons form? Scientists explore moon formation theories
We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon in our solar system ...

Moonbound Artemis II astronauts stay focused despite NASA uncertainty
It could be less than nine months before humanity ventures back to the moon, even if only to fly around it. The people set to make that flight were back on the Space Coast on July 30 to log time with their ride, the Orion ...

When Theia struck Earth, it helped set the stage for life to appear
How did Earth, alone among the solar system's rocky planets, become the home for life? How, among all this frigid lifelessness, did our planet become warm, hospitable, and life-sustaining? The answer to these questions is ...

Will asteroid 2024 YR4 hit the moon?
Asteroid 2024 YR4 made headlines earlier this year when its probability of impacting Earth in 2032 rose as high as 3%. While an Earth impact has now been ruled out, the asteroid's story continues.

The mother of all meteor showers could threaten satellites
Shortly after astronomers detected asteroid 2024 YR4 on December 27, 2024, they realized it posed no threat to Earth. But it could still impact the moon in 2032. The impact debris could threaten satellites and trigger an ...

Twin spacecraft mission reveals there might be a 'hot' side of the moon
The moon's nearside (that is, the side facing Earth) is dark-colored and dominated by ancient lava flows, whereas the farside is more rugged—and NASA researchers now suggest it's due to a wonky lunar interior. Using data ...

The moon is a constant source of minimoons
Earth has only one natural satellite, the moon, which is relatively large compared to its parent planet. It orbits Earth at an average distance of about 384,400 kilometers and completes one revolution approximately every ...

Asteroid impact threat estimates improved for the Earth and the moon
Asteroid 2024 YR4, first discovered in December 2024, triggered a first-ever notification from the International Asteroid Warning Network (IAWN) on January 29, 2025. The early calculations predicted an impact probability ...

Asteroid 2024 YR may not hit Earth in 2032, but it—and others—will keep coming back
In late 2024, astronomers spotted asteroid 2024 YR4 on a trajectory that could potentially threaten Earth. This observation triggered a fervid series of observations of the object—possibly as big as a football field—to determine ...
