Story summary

Astronomers have developed a detailed 3D map of stellar nurseries in the Milky Way using data from the ESA's Gaia space telescope.
This map covers 4,000 light-years, incorporating data from 44 million ordinary stars and 87 rare O-type stars.
It illustrates the connections between gas and dust clouds and the impact of massive stars on their surroundings.
Gaia's data enables precise distance measurements and assesses light extinction caused by dust.
The model corroborates previous radio and optical surveys, enhancing overall detail.
