Protostar L1527, shown in this image James Webb Space Telescope by the NASA/ESA/CSA,is embedded in a cloud of material that fuels its growth.
Material ejected by the star has cleared out cavities above and below it, their boundaries shining orange and blue in this infrared view. The upper-central region shows bubble-like shapes caused by stellar “burps” or sporadic ejections. Webb also detects filaments made of molecular hydrogen that have been impacted by past stellar ejections.
Interestingly, the edges of the cavities at the upper-left and lower-right appear straight, while the edges on the upper-right and lower-left are curved. The region on the lower-right appears blue, since there is less dust between it and Webb than there is in the orange regions above it.
