Observations of the outer Solar System with the Subaru Telescope have discovered new bodies where none were expected. The new objects are likely members of a much larger population waiting to be ...

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 ...

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...

Astronomers are closing in on one of the most tantalizing possibilities in planetary science, evidence that a previously unknown world may be lurking in the outer reaches of the solar system. The ...

Astronomers have made an extraordinary discovery at the outer edge of our solar system—a strange space rock that dances in perfect rhythm with Neptune. The object, named 2020 VN40, is part of a group ...

Astronomers studying the Kuiper Belt have detected a strange distortion that could point to an unknown planet lurking far beyond Neptune.

Tiny grains from asteroid Ryugu are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago. The findings suggest the distal solar system ...

Add Yahoo as a preferred source to see more of our stories on Google. A pellet of plutonium 238, illuminated by the glow of its own radioactivity. NASA and other space agencies use this material in ...

On January 14, 2005, the Huygens probe landed on Saturn’s largest moon, Titan. Huygens remains the first and only landing in any location in the outer solar system, the furthest distance from Earth a ...

The outer reaches of our Solar System continue to reveal a complex dynamical environment where the interplay of gravitational forces shapes the orbits of a myriad of distant bodies. Research in this ...

MIT scientists analyzed one of several particles (shown in black) from the asteroid Ryugu, and found evidence that a weak magnetic field likely existed in the outer solar system where the asteroid is ...
