Briefings

A Southwest Research Institute-led study utilized NASA's James Webb Space Telescope to analyze ice grains from interstellar comet 3I/ATLAS, identifying tiny water ice and dust aggregates smaller than a micron. This discovery marks the third interstellar object identified beyond our solar system, occurring in October 2026.

Key points

• The study identified tiny water ice and dust aggregates smaller than a micron from comet 3I/ATLAS.
• This is the third interstellar object identified beyond our solar system, occurring in October 2026.

Context

The findings provide new insights into interstellar objects and their potential origins, though the specific connection to interstellar space remains unconfirmed.

Limitations

The evidence is limited to a single study from October 2026; the specific connection to interstellar space is unconfirmed.
