Scientists detected a chemical shift in interstellar comet 3I/ATLAS as it neared the Sun.
Scientists observed interstellar comet 3I/ATLAS as it neared the Sun and detected a sudden shift in its chemical makeup, specifically a drop in carbon dioxide relative to water.
This change suggests the comet's interior is not uniform, with solar heating causing deeper, previously trapped layers to release different materials.
The findings provide new insights into the complex internal structure and origins of these rare interstellar visitors.
