Beneath the moon’s surface, magnetized lava can create ‘lunar vortices’

A dark grey high altitude view of the lunar surface, with tiny craters speckled throughout, and one large crater on the far right.

New research suggests that mysterious swirl patterns on the lunar surface may be linked to subsurface magma activity. The “lunar vortices“observed on the moon show a spiral pattern created by magnetized rocks that deflect or redirect the waves solar wind particles that constantly bombard the moon. Moon rocks that fall within the lunar vortices remain … Read more

Why do some planets have moons? A physics expert explains why Earth has only one moon, while other planets have hundreds

an illustration of an orange-and-red planet surrounded by four large moons

On Earth, you can look up at night and see the moon shining from hundreds of thousands of miles away. But if you went to Venus, that wouldn’t be the case. Not every planet has a moon – so why do some planets have multiple moons while others have none? I am a physics teacher … Read more

Graphene discovery in China’s Chang’e-5 moon samples challenges theory of moon’s origins

To understand the origins of this carbon, the Chinese research team said a study of young lunar samples – just 2 billion years old – could help them unravel “the crystalline structure of the native carbon” present on the moon. After analyzing the graphene found in the sample, the researchers concluded that the moon may … Read more

Why smaller planets are better at building big moons

a giant crescent moon hangs like a dim red bowl in a darkening re-clouded sky. A dark hilly landscape stretches beneath.

New simulations describing how moons, including Soil‘s own mohformed strongly implies that exomons are more likely to be found around rocky exoplanets. Our moon is thought to have that formed when a Mars-size planetesimal called Theia smashed into Earth, cutting a huge wound in our planet and melting its entire surface. It is believed that … Read more

Europa’s icy crust floats ‘freely’ over moon’s hidden ocean, new Juno images suggest

On September 29, 2022, NASA’s Juno spacecraft made its closest flyby of Europa, coming within 355 kilometers of the frozen surface of Jupiter’s moon. The close-up view of Europa revealed incredible details of the moon’s chaotic terrain, suggesting the icy crust is not where it once was. The images also showed a newly discovered feature … Read more
