Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected. Previous research suggests ...

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and ...

Our solar system is a smashing success. A new study suggests that from its earliest period—even before the last of its nebular gas had been consumed—Earth's solar system and its planets looked more ...

Scientists have shown that Earth’s basic chemistry solidified within just three million years of the Solar System’s formation. Initially, the planet was barren and inhospitable, missing water and ...

A new planetary system is forming around the young star HOPS-315. Scientists observed the earliest stages of planet formation around another star. The process involves the cooling and solidifying of ...

Peering through a cosmic keyhole at distant baby star, astronomers may have opened a new window on the deep past of our own solar system. Weighing in at 0.6 solar mass, HOPS-315 should someday grow to ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.

New simulations suggest that Mercury's formation could be the result of a rare collision between two celestial bodies of ...

The JWST has studied the chemical composition of a moon-forming disk circling a giant planet 625 light-years away.

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical ...
