A groundbreaking study published in Communications Earth & Environment has called into question the long-standing assumptions about how our solar system came to be. Tiny shavings from a meteorite ...

What specific processes are responsible for planetary formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of ...

A view of HOPS-315, a baby star some 1,400 light-years from Earth where astronomers have observed evidence for the earliest stages of planet formation. Combined with data from the James Webb Space ...

Most of our knowledge about the Solar System’s formation and evolution comes from the study of extraterrestrial rock samples called chondritic meteorites. These rocks, which are fragments of asteroids ...

What can a rocky molten exoplanet with an atmosphere teach astronomers about planetary formation and evolution? This is what ...

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.

Mercury is the innermost and smallest of the eight major planets in our Solar System, orbiting closest to the Sun. Though only slightly larger than Earth’s Moon, Mercury endures some of the most ...

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 ...

Jupiter is already the biggest planet by far in our solar system, but new research suggests it was somehow once even larger than it is now. Twice as large, in fact. To put that into context, those ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the ...
