Mercury is tiny, barely bigger than the Moon. Its metallic core makes up 70% of the planet’s mass, vastly exceeding Earth’s 32% and Mars ’ 25%. It’s unlikely that the core actually formed like this.

The formation of Mercury remains an unsolved mystery. The planet closest to the sun has a disproportionately large metallic core—accounting for about 70% of its mass—and a relatively small rocky ...

Higher-mass stars are more efficient in capturing interstellar objects in their discs,” said Susanne Pfalzner. “Therefore, interstellar object-seeded planet formation should be more efficient around ...

Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected.

The formation of Mercury remains an unsolved mystery. The planet closest to the Sun has a disproportionately large metallic core – accounting for ...

The main working hypothesis for the Mercury problem says that the planet is the victim of a collision with a different-sized object. The cataclysmic collision stripped much of the planet's mantle and ...

Scientists use the Frontier supercomputer to reveal how black holes and magnetic fields keep galaxy clusters stable for billions of years.

Scientists found that carbon enabled Earth’s core to solidify. Without it, the inner core may not exist. A team of scientists from the, University of Leeds, and University College London has uncovered ...

Scientists were surprised to notice that the Moon is rusting, a process that typically requires oxygen and water, both of which are scarce on the lunar body. According to Nature's report, Ziliang Jin, ...
