Far beyond Neptune, in the frozen depths of the Kuiper Belt, many ancient objects oddly resemble giant snowmen made of ice and rock. For years, scientists wondered how these delicate two-lobed shapes ...

A computer visualization maps small bodies in the solar system that are expected to be observed by the Rubin Observatory during the 10-year Legacy Survey of Space and Time. Red indicates near-Earth ...

Add Yahoo as a preferred source to see more of our stories on Google. A view of HOPS-315, a baby star some 1,400 light-years from Earth where astronomers have observed evidence for the earliest stages ...

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

Astronomers have long sought to understand the processes that lead to the birth of planetary systems. Recently, a major breakthrough was achieved as scientists witnessed the early stages of planet ...

When scientists want to understand the earliest history of our Solar System, they’ve typically turned to ancient meteorites. These celestial objects that come to Earth are remnants of the building ...

A research team led by University of Minnesota School of Physics and Astronomy Professor Yong-Zhong Qian uses new models and evidence from meteorites to show that a low-mass supernova triggered the ...

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 ...

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

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 ...
