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 ...

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 ...

Recent observations of the outer Solar System using the Subaru Telescope have uncovered objects where none were expected, hinting at the possibility of a larger and more complex structure in our ...

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 ...

Scientists were able to see the moment when planets began to form around a star. Astronomers have witnessed the birth of a solar system beyond our own for the first time. An international team of ...

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 ...

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 ...

A surprising discovery from a tiny grain of asteroid Ryugu has rocked scientists' understanding of how our Solar System evolved. Researchers found djerfisherite—a mineral typically born in scorching, ...

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 Sun's formation caused temperature differences in the surrounding disk of gas and dust. Inner, hotter regions formed rocky planets from less volatile elements. Outer, colder regions allowed ...
