Summary

Story summary

Astronomers observed the earliest stages of planet formation around the young star HOPS-315, 1,300 light years away.
They used the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array to detect minerals forming in the disc.
The study reports the first direct condensation of rocky building blocks, like silicate crystals, within about 2.2 astronomical units.
The findings bridge theory and observation and suggest consistent planet formation across young systems.
