Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in the Oort Cloud.

It's a new type of three-body problem for astronomers, who used the Hubble Space Telescope to determine that twin asteroids in the Kuiper Belt could be triplets.

M. Keck Observatory on Maunakea, Hawaiʻi Island, and NASA’s Hubble Space Telescope has likely discovered a stable trio of icy space rocks in the solar system’s Kuiper Belt. If confirmed ...

The Hubble finding is crucial support for a KBO formation theory, in which three small rocky bodies would not be the result of collision in a busy Kuiper Belt, but instead form as a trio directly from ...

The solar system extends beyond the Kuiper Belt and the scattered disc to the hypothesized Oort Cloud, an icy shell that might define the edge of the sun’s influence. Here, gravity weakens, and the ...

The Oort cloud can (in general) be split into an inner cloud and an outer cloud, with the inner cloud forming a rough disk shape and the outer cloud being relatively spherical. The inner and outer ...

"As the Galactic tide acts to decouple bodies from the scattered disk it creates a spiral structure in physical space that is roughly 15,000 AU in length," the study says. Which is approximately ...

MANILA, Philippines — Three weather systems are expected to bring overcast skies and scattered rainshowers across the country on Wednesday, February 26, according to PAGASA. In its 5 a.m. public ...
