A team of scientists accidentally visualized a hidden spiral in the Oort Cloud, and it might change everything we know about the solar system. Rachel Dillin Jun 11, 2025 11:26 AM EDT ...

The Oort Cloud is so far away from the Sun. (Representational) Scientists have long assumed the Oort Cloud, one of the most mysterious structures in our solar system, to be spherical.

An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

The existence of the Oort Cloud was first proposed in 1950 by Dutch astronomer Jan Oort, who imagined it as a shell of icy bodies swirling around the sun from up to 1.5 light-years away.

While the outer Oort Cloud might still be spherical, the inner part appears to twist in a spiral pattern, suggesting our solar system is more dynamically connected to the galaxy than once thought.
