On June 2, 2025, the American Museum of Natural History in New York held a planetarium show called Encounters in the Milky Way. During the show’s creation in 2024, scientists found something remarkable in the Oort Cloud, a place far from Earth with many icy objects. The Oort Cloud was once thought to be round. But now, new data from comets shows a spiral shape. The shape looks like a bar with curved arms, similar to the Milky Way. This interpretation was shared in The Astrophysical Journal and has gained much attention in the scientific community.

The spiral shape was made clear using computer models. These models were made by a scientist from the Southwest Research Institute. A planetary expert explained that the discovery is significant because it may change how people understand the outer solar system. Although the spiral cannot be seen with a telescope yet, changes in how comets move may prove it is real. The museum’s work shows how science and computer tools can help discover new things in space and establish better ideas about the solar system.
