Astronomers have spotted a planetary system being conceived from the swirl of gas and dust surrounding a star — giving us an unprecedented, real-time look at how our solar system would’ve formed some ...

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 ...

If you've ever wondered why we are here, then you can thank Jupiter for part of the answer. A new study from Rice University suggests that if it weren't for the gas giant, the Earth would have ...

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

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.

The Subaru Telescope has made an exciting discovery: a small body beyond Pluto, with implications for the formation, evolution, and current structure of the outer solar system. The object was found as ...

A tiny object far beyond Pluto, newly discovered by the Subaru Telescope, could reshape our understanding of the early Solar System. Named 2023 KQ14, this rare “sednoid” follows an unusual orbit that ...
