Summary

Story summary

Astronomers captured infrared images of RCW 94 and RCW 95 to study their structure and star formation.
The nebulae lie in the Norma arm of the Milky Way, a location relevant for galactic evolution.
The VISTA telescope reveals hidden stars and dust in infrared.
The VST shows glowing gas in visible light.
Together, the observations illustrate the interactions of ionized hydrogen gas with young stars and highlight ongoing star formation.

History

Historical Context

Launched in December 2009, NASA's Wide-field Infrared Survey Explorer (WISE) transformed infrared astronomy by mapping 99% of the sky and identifying over 500 million celestial objects. Its findings, including the discovery of new asteroids and star clusters, laid the groundwork for subsequent missions like NEOWISE, which continues to enhance our understanding of galactic evolution and star formation.
